It records 8 tracks of full-quality digital audio on standard Hi8 video cassettes using a speciallydesigned transport and head mechanism. Using this medium, up to 108 minutes of continuous recording is possible on a single NTSC "120" tape Recording is carried out at either 24 or 16 bits of resolution, and digital data may be input at 16, 20 or 24 bits of resolution. Analog signals are converted to digital data using 64 times oversampling delta-sigma techniques. The DA-78HR builds on the foundations laid by the TASCAM DA-88, DA-38 and DA-98 digital multitrack recorders, and retains compatibility with them. 16-bit tapes recorded on one of the DA series can be replayed and overdubbed on any other machine in the series, or any DTRS1 machine. 24-bit tapes can only be replayed in DA-78HR recorders, · Direct digital synchronization of up to 16 DTRS recorders (128 tracks) without the use of any external synchronizer or controller · Direct digital dubbing between DTRS units · An internal digital patchbay, allowing input-totrack assignment and selection of digital, analog and off-tape sources without the use of external switching or routing equipment · Internal 8 x 2 mixer (level and pan) for stereo replay of recorded tracks and output through a standard SPDIF connector without external mixing equipment · SPDIF stereo input · Balanced +4dBu analog inputs and outputs carried on a convenient compact D-sub connector · Unbalanced ­10 dBV connectors (RCA) for connection to semi-professional equipment · 15-segment peak meters with user-selectable fall ballistics and variable hold time (including continuous peak hold) · Meters also used for display of channel and track information · Integral digital sine oscillator, providing signals at 440Hz and 1kHz for tuning and other frequencies for lineup purposes · Digital input and output on a single convenient compact D-sub connector (TDIF-1 format) · Settings carried out through a menu hierarchy · SMPTE/EBU timecode input and output · MIDI Time Code and MIDI Machine Control · Simplified source/tape monitoring functions with automatic switching · Auto punch-in and punch-out with rehearsal mode · 2-point full function autolocator with A­B repeat function. · Variable speed recording and playback (up to 6.0% in 0.1% steps) · Shuttle mode enables "rock and roll" audio positioning of key locations · Data entry mode allows use of shuttle knob to set data values 1.1 Unpacking The box contains the following. · · DA-78HR Digital Multitrack Recorder (x 1) Accessories: ­Rackmount screw kit (x 1) ­AC power cord, 2 m (6 ft.) long (x 1) ­This manual (x 1) Warranty card (x 1) · 1.2 Features Other key features of the DA-78HR include: · TASCAM-exclusive high-performance/high wear resistive rotary 4-head mechanism with TASCAM original track layout (DTRS standard) · Use of standard, low-cost media with long recording and playback times · 24-bit or 16-bit linear quantization at either 44.1 kHz or 48 kHz provides CD-quality sound or better · Fast, frame-accurate tape location and positioning; end-to-end winding for a "120" tape is around 80 seconds 1. DTRS is a trademark of TEAC Corporation 1.3 Using this manual We suggest that you take the trouble to read this manual through at least once before starting to use the DA-78HR. In this way, you will find out where to turn when you need answers. TASCAM DA-78HR 7 1 - Introduction to the DA-78HR We suggest that you make a special note of the section 1.4, "Precautions and recommendations" as these contain some information which is unique to the DA-78HR. We also suggest that you also read , as this will help you when you come to perform basic operations. When referring to a control or a connector on the DA-78HR, the name of the control or connector will be written in bold type, and may be followed by a number, as in the example below: Holding down the PLAY key C and pressing the REC D key will start the recording process. The numbers refer to the front and rear panel illustrations and description in this manual. When referring to a word or phrase which appears on the display, the word or phrase will be written as follows: MEMO. 1 ( MEMO 1). 1.4.1 Clock source in a digital studio The DA-78HR can be used in a variety of situations, and with a variety of equipment, either digital or analog. If you are working with more than one digital audio unit in your setup, you should note that all units must be driven by the same central clock source ("word clock" or "word sync"). If different word clock sources are used throughout the setup, it is actually possible to damage speakers, etc. because of mismatches. The DA-78HR can be designated as the word clock master for your studio, or can be slaved to external word clocks, using a convenient front-panel switch and standard BNC connectors. Even though AES/EBU stereo digital audio signals are self-clocking, any AES/EBU format signals converted and fed to or from the DA-78HR must be synchronized at word level with the DA-78HR. If on-screen parameters are given as part of a display example, they may sometimes be shown in the following way, where the ;; represents an unknown value: ID SEL ;; ( ID SEL xx ), where xx is the 1.4.2 HR recording and emphasis Recordings made in 24-bit (HR) mode do not use emphasis. If an attempt is made to record a digital signal that contains emphasis using either the TDIF or the SPDIF digital audio inputs, the display shows E EMP (E EMP), and the signal is muted. A digital emphasis circuit is provided, however, for compatibility with previous models of DTRS recorder. Note that if a recording using emphasis is dubbed to the DA-78HR via the analog inputs, this signal will need to be modified appropriately. machine ID NOTE Recording is an art as well as a science. A successful recording is often judged primarily on the quality of sound as art, and we obviously cannot guarantee that. A company that makes paint and brushes for artists cannot say that the paintings made with their products will be critically well-received. T ASCAM can make no guarantee that the DA-78HR by itself will assure the quality of the recordings you make. Your skill as a technician and your abilities as an artist will be significant factors in the results you achieve. 1.4.3 Environmental conditions The DA-78HR can be operated in most environments, but we suggest that you keep the environmental conditions within the following limits: · Ambient temperature between 5°C and 35°C (41°F and 95°F). · Relative humidity should be between 30% and 80% non-condensing · There should be no strong magnetic fields (speakers, etc.) near the DA-78HR. · Avoid spraying polish, insecticides, etc. near the DA-78HR. NOTE 1.4 Precautions and recommendations As with any precision piece of electronic equipment, common-sense precautions apply with the DA78HR. However, there are a few extra precautions which apply to the DA-78HR, and we suggest that you make a note of these, to prolong the useful life of the DA-78HR. If you need to clean the DA-78HR, use a soft cloth, moistened if necessary with a little detergent and 8 TASCAM DA-78HR 1 - Introduction to the DA-78HR water. Do not use abrasive cleaners or solvents such as alcohol or thinner. 1.4.6 Three-core power cord In order to maintain the best possible audio quality, the DA-78HR is supplied with a 3-core (grounded) power cord. DA-78HR should be used with a grounded power cord, connected to a suitable electrical ground, at all times. If it is not, there is a possibility that the audio quality will suffer. Avoid subjecting the DA-78HR to jolts, sudden shocks, etc. NOTE -- I M O TA T PR N If you have to return the unit for service or repair, use the original packing materials if possible. If the unit is to be transported to a recording location, etc., use a suitable transport case with sufficient shock protection. 1.4.7 Powering the DA-78HR off and on When powering the DA-78HR off and on, always wait for five seconds or more between powering the unit off and turning it on again. If the power is switched too quickly, the precision power supply may not provide the power of the proper quality required for recording. If power is inadvertently switched off an on quickly, and the power supply does not respond properly, switch the unit off again, wait for five or more seconds, and switch it on again. TASCAM does not accept responsibility for damage resulting from neglect or accident. 1.4.4 Installing the DA-78HR The DA-78HR may be installed in a standard 19" rack, occupying 3U of space. Since the DA-78HR is quite heavy (around between 7 and 8 kg ­ about 16 lb.), your rack should be strong and stable to take the weight of the DA-78HR. The DA-78HR should be mounted with the front panel vertical. 1.4.8 Condensation If you use the DA-78HR in a warm place after moving it from a cold place (for instance, recording on location), or if there has been a sudden change in temperature, condensation may occur within the tape mechanism, with a risk of possible damage to the unit. If condensation does occur, you will not be able to operate the DA-78HR controls, and you will see the following message on the display E DEW ( E DEW ). If you see the above message, leave the DA-78HR switched on for one or two hours, then switch it off and on again before starting recording. If you are going to use the DA-78HR in a location where you think condensation is likely to occur, move the DA-78HR into the warmer location about one or two hours before recording is due to start, and leave it switched on. Turn the DA-78HR off and then on again before starting recording. 1.4.5 Electrical considerations Make sure that your local power supply matches the voltage requirements marked on the rear panel of the DA-78HR. If you are in any doubt concerning the local power supply, consult an electrician. Avoid extreme voltage fluctuations. If necessary, use an input voltage regulator to smooth the power supplied to the DA-78HR. Do not open the unit to clean inside, or to perform any internal adjustments. You should not attempt any cleaning or other maintenance procedures which are not described in this manual. You may need to clean the heads occasionally. The procedure for doing this, and for checking tape error rates, etc., is given in 11.1, "Head and transport cleaning". 1.5 Recommended tapes The DA-78HR is designed for use with Hi8 video cassettes. You cannot use any other kind of tape with the DA-78HR. Always use new tapes, or tapes in the best possible condition, in order to achieve the best possible results when recording. Tapes which have been over-used will not give such good results as new tapes. TASCAM DA-78HR 9 1 - Introduction to the DA-78HR There are two basic types of Hi8 tape: MP and ME. Each has its own particular characteristics and merits: · MP tapes are manufactured using a daubed magnetic particle deposit process and exhibit a level of performance which is more than acceptable. They have a durability which allows them to be used as work tapes in studio and post-production environments. · ME tapes have their magnetic layer produced through a metal evaporation process. Generally speaking, though these tapes have a high performance level, they are not as robust as MP tapes (see above) and should be used for live recording and archival purposes, rather than as work tapes. TASCAM does not endorse any specific tape or tape manufacturer. TASCAM has licensed the use of the DTRS logo ( TM) to tape manufacturers, provided their tape meets the specifications required by DTRS tape recorders. The table below lists several such tapes, certified for use with DTRS tape recorders. However, the use of the DTRS logo on the tape packaging does not imply any endorsement of the tape by TASCAM. It is possible that the characteristics and sensitivities of tapes may be changed by the manufacturers without notice. The brands and model numbers of tapes listed below may not always meet the specifications required by DTRS systems for optimum performance. TASCAM assumes no responsibility for problems resulting from changes made by a manufacturer to the materials or specifications of its tape products. The electrical characteristics of DTRS recorders are adjusted and set using Sony Hi8 tape parameters (MP and ME) prior to shipment. this brand and model name will continue to give optimum performance. Maker MP ME Sony DARS-MP P6-HMP P6-HMPX P5-HMP P5-HMPX E6-HME E5-HME E6-HMEAD E5-HMEAD E6-HMEX E5-HMEX Quantegy DA8 MP BASF HHB Maxell Fuji DA MP DA113 DRS-113DA (P) DPD-MP The electronics of DTRS recorders are designed to operate within specific parameters. The use of a tape with sensitivity higher or lower than that of tapes for which the DTRS recorder was originally designed may cause an error in functionality or prevent the user from getting optimum performance from the tape. Always use the shortest possible tape for a given project. Do not attempt to use 150-minute or longer tapes in DTRS machines, as the machine will detect the thickness of tape and automatically eject any tape thinner than recommended. Never attempt to use a tape with the DA-78HR that has previously been used in video equipment. NOTE -- I M O TA T PR N 1.5.1 Tape brands The following brands and models of tape can be used with the DA-78HR. As mentioned above, this list does not constitute any endorsement by TASCAM of these products, nor is it a guarantee that tapes bearing You cannot cut and splice DTRS 8mm tapes for editing purposes. Using a spliced tape in the DA-78HR will invariably result in serious damage to the heads, requiring replacement. All editing must be done digitally. 10 TASCAM DA-78HR 1 - Introduction to the DA-78HR 1.5.2 Available recording and playback time Depending on whether the tape has been purchased for use with an NTSC (P6/E6) or a PAL/SECAM (P5/E5) television system, the same length of tape (as far as video length is concerned) will provide different times for audio work, as shown below, due to different frame rates between television systems. The indication P6/E6 or P5/E5 will be printed on the tape package: Time on tape label 20 30 45 60 90 120 P6/E6 (NTSC tape) 18 27 40 54 81 108 P5/E5 (P AL/ SECAM tape) 25 37 56 75 113 ­ TASCAM DA-78HR 11 2 - Front and rear panel features 12 TASCAM DA-78HR 2 - Front and rear panel features 2.1 General controls and indicators 1 Power switch Turns the power to the DA-78HR on and off. When the DA-78HR is turned off, settings will be retained in memory. Legend OFFSET Meaning Section 2 Tape loading slot and EJECT key Only use Hi8 ME or MP tapes as specified in 1.5, "Recommended tapes". The DA-78HR will automatically eject all other tapes. NOTE --I M O TA T PR N Machine or timecode offset is in 8.3.1 and operation 9.6.2 When both of these are lit, the DA-78HR is using internal word CLOCK (WORD)sync, and when neither is lit, word sync is being received through the REMOTE IN/ 3.2 SYNC IN connector. If one is lit, the word sync is being CLOCK received through the appropri(DIGITAL IN) ate connector (digital audio (COAXIAL) or word sync). TAPE TC Lights when the DA-78HR is reading timecode from the tape 9 Do not use a tape which has been used for recording video. Always use either new tapes or tapes which have been used in a DTRS recorder. 7 Tape counter The tape counter gives the current tape time in hours, minutes, seconds and frames. It is also used to display menus, sub-menus and the values of the parameters of the unit, as well as providing information on the current status of the unit. The EJECT key ejects any loaded cassette. A cassette can only be ejected when the transport is stopped. 3 FORMAT/Fs key The FORMAT/Fs key controls the formatting of tapes and allows selection of the sampling frequency used for recording (see 5.1, "Formatting a tape" for full details). The current sampling frequency is shown on the status indicators 6. 8 PB CONDITION indicator There is one more indicator: PB CONDITION , which lights if there are many errors when reading or recording the tape. It also flashes when the block error rate is being checked (11.1.2, "Checking error rates"). If this lights frequently, the block error rate can be checked and the heads cleaned (11.1, "Head and transport cleaning"). 4 HR MODE key This key allows the selection of the recording resolution (16-bit or high-resolution 24-bit). See 5.1, "Formatting a tape" for details. The appropriate indicator 6 will light if the HR mode is selected. 5 CLOCK key This is used to select the word sync source for the DA-78HR (either internal, WORD or DIGITAL IN , as shown on the indicator 6). 2.2 Tape transport keys and controls 9 REW key Rewinds the tape at high speed. If this key is pressed during recording, recording will stop and the tape will rewind. 6 Status indicators The status indicators show the current status of various DA-78HR functions. The legends of these indicators are abbreviated for reasons of space. Here is a list of their full meanings, together with the pages on which the functions are more fully described: Legend HR Fs (44.1k) Fs (48k) ABS M eaning High-resolution (24-bit) mode Either of these will light to show the current sampling frequency T ape subcode (ABS) is being used as the timing reference A F FWD key Winds the tape forward at high speed. If this key is pressed during recording, recording will stop and the tape will wind forward. NOTE Section 5.1 5.1 9.1 When either REW or F FWD is pressed for the first time after powering up, or loading a tape, the unit first configures itself for the reel hub diameter of the tape in use, during which the tape advances at low speeds. This takes several seconds. Thereafter, the 13 TASCAM DA-78HR 2 - Front and rear panel features transport momentarily goes into stop mode before the tape starts fast-winding. F SHIFT key and indicator Controls the behavior of the other keys (see 4.2, "The SHIFT key" for details). B STOP key Cancels any current tape transport mode, and stops the tape. If pressed in chase mode, cancels the mode and stops the tape. G RHSL (DELAY) key and indicator This key and indicator allow selection of the rehearsal mode in auto punch-in and out (5.6, "Punch-in and punch-out"). When the DA-78HR is in shift mode, this key allows the setting of track delays (7.3, "Track delay"). C PLAY key Starts playing the tape. If this key pressed while recording is in progress, the DA-78HR drops out of record mode. D RECORD key If the PLAY key C is pressed while the RECORD key is held down, recording will start on all "armed" tracks (5.2.1, "Preparing to record"). If the DA-78HR is in play mode, and the REC key is pressed, recording will start immediately on any "armed" tracks. The RECORD key also is used to set punch-in points during auto punch-in/out operations (5.6, "Punch-in and punch-out"). H AUTO IN/OUT (OFFSET) key and indicator This key and indicator allow automatic punch-in and punch out following rehearsal (5.6, "Punch-in and punch-out"). When the DA-78HR is in shift mode, this key allows the setting of chase offsets (8.3, "Machine offset" and 9.6.2, "Timecode offset"). I CLEAR (PRE ROLL) key This key defeats the rehearsal and auto modes during auto punch-in and out (see 5.6, "Punch-in and punchout"). It can also be used to cancel a format operation (5.1, "Formatting a tape"). When the DA-78HR is in shift mode, this is used to set pre- and post-roll times (5.6.4, "Editing the preroll and post-roll times" and 7.1.3, "Setting the location pre-roll time"). E DATA/LEVEL control When the SHUTTLE/DATA key is pressed, the indicator will light. The DATA/LEVEL control will then be active as a shuttle control. Turning the control to the right provides forward cueing and turning it to the left provides reverse cueing, similar to "rock and roll" on open-reel tape decks. For details, see 7.7, "Shuttle operations". When the SHUTTLE/DATA key is pressed in conjunction with the SHIFT key, the DATA/LEVEL control is also used as a data entry control to make various settings, including the sub-mixer settings. See 4.3.7, "Using the DATA/LEVEL knob to set values" and 7.4, "Sub-mixer" for details. J VARI SPEED / PITCH key and indicator Used to set the varispeed (pitch) amount, and to turn the function on and off (see 7.6, "Vari speed (pitch control)". K ALL INPUT (w) key and indicator This key is used to switch the monitoring mode so that the outputs mirror the inputs (see 6.1, "ALL INPUT"). 2.3 System control keys The following keys all provide access to more advanced functions of the DA-78HR. Many of them are also used in the menu system to view and set system parameters. See 4, "Menu interface, etc." for details. Many of them also serve two functions, as shown by the blue "shifted" legends below the unshifted legends (shown here in parentheses). See 4.2, "The SHIFT key" for details. L AUTO MON (v) key and indicator This key is used to change the monitoring mode to change automatically in punch operations (see 6.2, "AUTO MON"). In menu mode and when editing parameters, this acts as a key to select and change (increment) parameters. When used with the SHIFT key, it acts as a cursor key. TASCAM DA-78HR 14 2 - Front and rear panel features M REPEAT (MENU) key and indicator This key is used to provide a repeat function between the two location points (see 7.2, "Repeat function"). When the DA-78HR is shift mode, it allows selection of the top-level menus (see 4.3, "Menus and submenus"). functions. See 7.3, "Track delay", 7.4, "Sub-mixer" and 5.3, "Input selection" for details of these operations. S Peak meters These 15-segment peak meters show the input level or the recorded signal level, depending on the monitoring mode currently in operation (6, "Monitoring"). NOTE N CHASE (SUB MENU) key and indicator This key is used to set the DA-78HR to a slave chase mode, either to another DTRS unit, or to timecode (see 8.2.3, "Master/slave settings (CHASE mode)" and 9.6, "Chasing to timecode"). When the DA-78HR is in shift mode, it allows selection of the second level of menus in the menu tree (see 4.3, "Menus and sub-menus"). When using digital recording equipment, there is no headroom above the 0 dB mark and no tape saturation is possible. Any signal which causes the "OVER" segment to light will cause audible distortion. For this reason you should take care not to let recording levels exceed this level. The ballistics and peak hold times are selectable (see 7.8, "Meter modes"). They may also be used to provide a quick visual guide to the status of some of the settings (sub-mixer, patchbay, etc.). See 4.1.1, "Peak meters" for details. O LOC 1 (MEMO 1) key This key locates the tape to the position set by MEMO 1 (this key used with the SHIFT key). See 7.1, "Autolocation" for details. P LOC 2 (MEMO 2) key This key locates the tape to the position set by MEMO 2 (this key used with the SHIFT key). See 7.1, "Autolocation" for details. 2.5 Rear panel features See 3, "Connections" for full details of how to connect the DA-78HR to other units. Q MIXDOWN (LEVEL/PAN) key and indicator This key turns the 8 x 2 sub-mixer output on and off from the rear panel outputs. See 7.4, "Sub-mixer" for details. When the DA-78HR is in shift mode, this key is used to set the level and the pan position of each track in the sub-mixer image (7.4, "Sub-mixer"). T REMOTE IN/SYNC IN This connector is used to connect another "master" DTRS unit (e.g. DA-78HR, DA-98, DA-88 or DA38). See 8, "Synchronization with other DTRS units" for further details. A TASCAM remote control unit may also be connected here, but not all functions of the DA-78HR may be available from the remote control unit. U MIDI IN/OUT/THRU 2.4 Track controls R REC FUNCTION keys and indicators These eight switches and indicators allow the setting and viewing of the record status on a track-by-track basis. When one of these switches is pressed, the appropriate indicator will flash, the track is "armed", and going into record mode will start recording on that track. When recording is being carried out on a track, the track's indicator will light steadily. In addition, these keys are also used to select tracks and channels for different operations, including the input and output patchbays, the delay and sub-mixer These connectors carry MIDI Time Code (MTC) and MMC (MIDI Machine Control) commands as well as MIDI System Exclusive messages. See 10, "MIDI control" for details of how these facilities are used when synchronizing to other units. V SYNC OUT This is used to connect another DTRS unit in the "daisy-chain" or, if this DA-78HR is the last unit in the chain, to attach a termination plug. W REMOTE IN Use this to connect an optional RC-808 remote control unit. Note that not all features of the DA-78HR can be controlled using the RC-808. 15 TASCAM DA-78HR 2 - Front and rear panel features X REMOTE PUNCH IN/OUT Use this to connect an optional RC-30P footswitch to control punch operations. Y TDIF-1 (DIGITAL I/O) This connector carries the digital signals to and from the DA-78HR in TEAC Digital Interface Format (TDIF-1). c ANALOG INPUTS (unbalanced) These eight RCA connectors accept unbalanced analog audio inputs at ­10 dBV. d ANALOG INPUTS (BALANCED) This connector carries 8 balanced inputs at a nominal +4 dBu level. This allows convenient and reliable single-cable connection to the GROUP outputs of a suitably-equipped console such as the TASCAM M1600 series. Z TIME CODE (IN, OUT) These RCA connectors are used to carry SMPTE/ EBU timecode to and from the DA-78HR. For details of using the DA-78HR with timecode synchronization, see 9, "Operations related to timecode". e ANALOG OUTPUTS (unbalanced) These eight RCA connectors output unbalanced analog audio signals at a ­10 dBV level. a WORD SYNC (IN, OUT, THRU) These BNC connectors are used to carry the word clock between the DA-78HR and other types of digital audio equipment. The THRU connector is autoterminated (i.e. there is no need for a terminator when this is unconnected). f ANALOG OUTPUTS (BALANCED) This connector carries 8 balanced outputs at a nominal +4 dBu level. This allows convenient and reliable single-cable connection to the tape return inputs of a suitably-equipped console such as the TASCAM M1600 series. b DIGITAL IN, OUT (COAXIAL) These RCA connectors provide an SPDIF stereo digital audio signal containing the submix signal (OUT) or accept an SPDIF signal (IN ) for recording (see 7.4, "Sub-mixer" and 5.3.1, "Digital input selection"). g ~ IN Use the provided AC power cord to connect the DA78HR to the AC power supply through this connector. TASCAM DA-78HR 16 3 - Connections This section explains how to connect other equipment to the DA-78HR. It is not intended as a complete reference to the use of the DA-78HR. See the appropriate sections for full details of how these connectors are used. NOTE S --I PO R N M TA T The pinouts for both the ANALOG OUTPUT and INPUT connectors are as follows: When making connections between the DA-78HR and other equipment, whether audio or control, both the DA78HR and the other equipment must be turned off, otherwise damage may be caused to the DA-78HR and/or the other equipment. Only use TASCAM-supplied and TASCAM-approved cables when making connections to the DA-78HR. Though the cables and connectors may resemble computer cables, they serve different purposes, and meet a different set of specifications. The use of cables other than TASCAM cables will at best cause the equipment to work erratically, and at worst cause damage to the equipment. where G=ground, H="hot" (+) and C="cold" (­). The impedance of the inputs is 20k and that of the outputs is 10. 3.1.2 Unbalanced analog audio connections In addition to the balanced analog set of connections, there are eight RCA jacks for input signals and eight for output. These are, of course, unbalanced, and the nominal signal level is ­10 dBV. NOTE If the use of cables other than T ASCAM cables causes or results in damage, the warranty is voided. 3.1 Audio connections Other audio equipment can be connected to the DA78HR either using analog or digital interfaces. Selection for the input source (analog or digital) on a global or individual track basis is made from the menus. See 5.3, "Input selection" for details. Only connect and use one set of analog inputs at a time. There is no facility to switch between the two sets of analog input connectors. 3.1.3 Digital audio connections Multitrack digital audio input and output signals are carried on a single 25-pin D-sub connector. The signals are in TDIF-1 format. To carry signals between a DA-78HR and another unit equipped with TDIF-1 interfaces, such as the TASCAM series of digital mixing consoles or other DTRS recorders, use a PW-88D cable (1 meter long) or a PW-88DL cable (5 meters long). If you need to connect the DA-78HR to a digital audio source using a different format, we recommend the use of the following units: · TASCAM IF-88AE Interface Unit--converts between the TDIF-1 and AES/EBU formats (8 channels). It also provides SPDIF format conversion facilities. TASCAM IF-AE8--also provides sophisticated conversion facilities between the TDIF1 and AES/EBU data formats. TASCAM IF-88SD Interface Unit--converts between the TDIF-1 and SDIF-2 digital audio formats. The TASCAM IF-TAD--converts between the TDIF-1 and ADAT data formats, using a digital optical input/output for the ADAT data. 3.1.1 Balanced analog audio connections All balanced analog input and output audio connections to the DA-78HR are made through 25-pin Dsub connectors. All these audio inputs and outputs are balanced and are rated at a nominal +4dBu level. This allows convenient and tidy cabling between the DA-78HR and other units such as the TASCAM M1600 series of mixing consoles. It is not recommended that you make up your own cables--consult your TASCAM dealer for availability of suitable ready-made cables (and see 12.1.8, "Cables"). However, we recognize that every situation has its own unique features, and there are occasions when a special cable must be made. Before starting to make the cable, we suggest you contact your TASCAM dealer for full details of cable specifications, etc. · · · TASCAM DA-78HR 17 3 - Connections 3.1.4 SPDIF connectors The coaxial RCA digital audio connectors on the rear panel allow connection of an SPDIF-equipped device (e.g. a DAT recorder). This digital unit should be used as a clock source if data is to be read from it When synchronizing to the signal received at the COAXIAL DIGITAL IN, set the CLOCK key so that the DIGITAL IN indicator lights. 3.2.3 Timecode connections The DA-78HR can be synchronized to externallygenerated timecode and is also equipped with an internal timecode generator. SMPTE/EBU timecode can be received at the TIME CODE IN RCA jack, and can be transmitted from the TIME CODE OUT RCA jack. See 9, "Operations related to timecode" for details. 3.2.4 MIDI timecode connections The three MIDI connectors, IN, OUT and THRU , conform to the MIDI standards for such connectors. 3.2 Synchronization connections The DA-78HR has facilities for control and synchronization with other units. For full details of how to operate the DA-78HR with other units, see 8, "Synchronization with other DTRS units" and 9, "Operations related to timecode". 3.3 Connection to other TASCAM units By a "TASCAM unit", we mean another DA-78HR, a DA-98, DA-88 or a DA-38 unit, or an optional remote control unit, which may also be connected in a "chain" with multiple DTRS units. 3.2.1 Word clock connections This set of BNC connectors is used to synchronize the DA-78HR to other digital audio devices. The CLOCK key is used to change between clock sources, and should be set to WORD when synchronizing to an external word clock (the WORD indicator will light). The IN jack should be connected to the WORD SYNC OUT of the digital audio device from which the DA-78HR is to receive the synchronization clock. The OUT outputs word clock information provided from the DA-78HR, while the THRU, to echoes the signals received at IN . Note that if the DA-78HR is connected to other DTRS units, the WORD SYNC jacks do not need to be connected between the DTRS units. 3.3.1 REMOTE IN This jack on the rear panel can be used to connect a remote control unit such as RC-808 remote control unit. Basic control can be carried out using this unit, but more advanced operations will not be possible. 3.3.2 Footswitch A footswitch such as the optional TASCAM RC-30P footswitch can be connected to the REMOTE PUNCH IN/OUT jack on the rear panel. This footswitch allows hands-free punch-in and punch-out. When a track or track is armed, and the unit is in play mode, pressing the footswitch once will drop the unit into record mode, and pressing it again will drop it back into play mode. The footswitch, rather than the transport keys, can also be used to set punch points, as described in 5.6, "Punch-in and punch-out". 3.2.2 MIDI connectors (IN , OUT and THRU) These standard 5-pin DIN MIDI connectors are used to carry MIDI Time Code (MTC) and MIDI Machine Control (MMC) information between the DA-78HR and other suitably-equipped units (for instance, sequencers capable of being synchronized to MTC, and capable of transmitting MMC commands). The MIDI parameters are set through the menu system (see 10, "MIDI control"). Note the difference between MIDI OUT and MIDI THRU. The OUT connector outputs signals which originate from the DA-78HR. The THRU connector echoes messages received at the IN. 3.3.3 Multiple DTRS units Use a TASCAM PW-88S cable when connecting other units to the REMOTE/SYNC IN connector or to the SYNC OUT connector. This synchronization cable will carry the internal synchronization code and the transport signals, etc. There is no need to make any other connections, 18 TASCAM DA-78HR 3 - Connections apart from the audio connections (either digital or analog). If more than one DTRS unit is to be used, the first unit in the chain must have its Machine ID set to "1", ("0" in the case of DA-88s) and subsequent units must have their IDs set in order with no gaps in the numbering sequence. Note that the diagram below does not show any audio connections. Machine ID 1 (master) Machine ID 2 (slave 1) Machine ID 3 (slave 2) Machin e ID 1 (m aster, bu t CLOCK se t to WORD) 3.3.4 "Indirect" word sync As mentioned earlier, there is usually no need to use a word clock when connecting DTRS units together. There is, however, an occasion when it is necessary to carry external word sync between DTRS units. This is when a slave DTRS unit is recording digitally from another digital audio device: Dig ital SDIF-2 d evice Word clock sig nal Mach ine ID 2 (slave 1) SDIF -2 digital aud io PW-88S PW-88S Termination plug PW-88S Termin atio n TDIF -1 d igita l plu g aud io IF -88SD See 8.2, "Machine ID and master/slave settings" for details of setting the Machine ID using the menu system NOTE The last unit in the chain must be terminated (a TASCAM termination plug must be plugged into the SYNC OUT of the last machine in the chain. Once again, only use TASCAM cables for connection of equipment to and from the DA-78HR. Though the slave will receive its word clock from the master unit, the master itself must receive its word clock from the other digital audio device. In this case, the master unit will have its clock source set to WORD, and the slave will receive its clock from the master unit through the SYNC IN . TASCAM DA-78HR 19 4 - Menu interface, etc. Read this section to understand the basic principles of the menu operations. These menus are used for making settings which cannot be made directly from dedicated front panel keys. In addition, this section gives a brief description of the top-level menu groups as well as the sub-menu items and the parameters. This is not a detailed description of these menus and parameters, but may be consulted for quick reference. See the appropriate sections of the manual for detailed information regarding these menu settings. graph display to show the "fader" settings of the track levels. Typically, the higher the value of the parameter, the more segments of the meter are lit (at minimum values, no segments are lit, at maximum values, all segments are lit). Pressing and holding SHIFT and pressing any REC FUNCTION key in these editing modes will toggle the meters between data value display and the normal meter display. 4.1 The display The DA-78HR's menus and their options are displayed using the time counter. Since the display is composed of 7-segment LED counters, a special alphabet is used to show the letters of the alphabet. The characters on the DA-78HR time counter are shown as in the table below: A A L L W W 7 7 B B M M X X 8 8 C C N N Y Y 9 9 D D O O Z Z . E E P P 0 0 . F F Q Q 1 1 xa ; G G R R 2 2 H H S S 3 3 I I T T 4 4 J J U U 5 5 K K V V 6 6 4.2 The SHIFT key The SHIFT key serves two functions: first, to modify the action of another key when the SHIFT key is pressed and held while the other key is pressed, and secondly, to enter "shift mode". These two are explained below. 4.2.1 Shifted keys Some keys of the DA-78HR perform two functions, labels associated with the key. For instance, the LOC 1 (locate to memory position 1) key, has the alternative "shifted" function marked as MEMO 1 (store the current time into memory location 1). When the SHIFT key is pressed and held down, and one of these keys, as described in the relevant part of this manual, is pressed, the shifted function will be performed. The two keys can then be released in either order (either the SHIFT key or the other key can be released first). a. This is a lowercase "x", used to denote an unknown value. 4.2.2 Shift mode By contrast, pressing the SHIFT key alone and releasing it will place the unit into "shift mode". The SHIFT indicator flashes to show this. Pressing any of the two-function keys while the unit is in shift mode will automatically enter the shifted function. While the unit is in shift mode, pressing the SHIFT key once again will turn the indicator off and exit SHIFT mode. Note, however, that pressing and holding the SHIFT key and pressing another key to access the shifted function of that key will not affect the current shift mode.
