Introduction to the DA-40 The DA-40 Digital Audio Tape (DAT) deck is referred to throughout this manual as "the tape deck". Please make a note of the different sections of this manual to assist you in locating the function you need. The index should also be of use in helping you to find the correct section of the manual. · the ambient temperature should be between 5° C and 35° C (41° F to 95° F) · the relative humidity should be between 30% and 60% (non-condensing) · the tape deck should not be located near any strong magnetic fields (TV sets or monitors, speakers, etc.) The tape deck may be mounted in a standard 19 inch EIA rack using the supplied rack mounting screws. Make sure that the rack is strong enough to take the weight of the tape deck (over 8 kg-- 17 lbs.). 1.1 Features The tape deck provides the following features: · Superior quality digital-to-analog and analog-todigital conversion for maximum sonic fidelity · Extended long-play option, allowing twice the standard recording time. · AES/EBU and SPDIF digital audio input and output formats for full flexibility · Balanced (+4 dBu) and unbalanced (-10 dBV) analog inputs and outputs · Comprehensive display options, showing elapsed time, time remaining on the tape, etc. · Character entry and editing, allowing tape and program titles to be displayed as the tape is played · Optional wired remote control unit (RC-D45) for control of all major functions · Shuttle facilities, allowing precise positioning of the tape using audio cues · Location to frame accuracy to location memories · Comprehensive menu options, allowing many everyday function settings to be set up and memorized 1.2 Unpacking and inspection When you first receive the tape deck, be careful not to damage it while unpacking it. Save the carton and packing materials in case it must be transported later. In addition to the tape deck itself, the carton should contain a rack mount screw kit . If any items are missing or appear to have been damaged in transit, contact your TASCAM dealer at once. WARNING If the tape deck is mounted in a mobile installation, and it is moved from a cold location to a warm one, leave the tape deck turned on with no tape inserted to allow the internal temperature to stabilize before the tape deck is used again (about one or two hours). This will prevent any possible damage to the heads, and other parts of the internal mechanism. 1.4 About DAT cassettes If you have not used a DAT recorder before, here are a few items of information about DAT cassettes and their use with the tape deck which you may find useful: The cassette shell of a DAT cassette is designed to prevent the tape from being touched by hand. Never try to open the tape protection lid and touch the tape. Fingerprints on the tape may cause wear and damage to the tape deck heads. DAT cassettes can only be loaded and unloaded when the tape deck is switched on. Do not leave cassettes in the deck when the deck is switched off. 1.3 Installation of the tape deck The tape deck may be installed in most studio-type environments, but to maintain optimum performance and to maximize the life of the tape deck, the environment should meet the following specifications: 6 TASCAM DA-40 1 - Introduction to the DA-40 Always store DAT cassettes in their plastic cases to prevent dust damage. Keep them away from magnetic fields (TV sets and monitors, speakers, etc.) Although 180-minute DAT cassettes are available, we do not recommend their use, as the tape in these cassettes is thin, and may cause winding problems, and physical damage to the tape. DAT cassettes play in one direction only. Always load DAT cassettes with the tape window uppermost, and the arrow on top of the cassette pointing into the tape deck, as illustrated below: 1.5 Making connections NOTE Before making any audio connections to the tape deck, make sure that all equipment is turned off. 1.5.1 Making analog connections Use balanced cables to make connections between the BALANCED INPUT (female) and OUTPUT (male) XLR connectors of the tape deck, and the outputs and inputs of other audio equipment operating at the professional +4 dBu level. The wiring standards for the XLR connections are printed on the rear panel of the tape deck (1 = ground, 2 = hot, 3 = cold) Use unbalanced cables to make connections between the unbalanced input and output RCA connectors of the tape deck and the outputs and inputs of audio equipment operating at other levels. 1.5.2 Digital formats Previously, the professional and consumer digital audio formats were referred to as "AES/EBU" and "SPDIF". In this manual, they are referred to by their official names as "AES/EBU3-1992" and "IEC60958" formats respectively. Please note that there is no change to the data format--this is a name change only. NOTE Start recording on a new blank tape from the beginning of the tape. There is no need for a lead-in section, and recording from the start of the tape will record the subcode from the start, allowing accurate positioning within the tape. Also note that DAT cassettes are fitted with a sliding write-protect tab to prevent accidental recording. The cassette is write-protected when the tab is closed. 1.5.3 Making digital audio connections Use cables wired in accordance with the AES/EBU standard to connect the DIGITAL (AES/EBU) INPUT (male) and OUTPUT (female) XLR connectors of the tape deck to other digital audio equipment. Use unbalanced cables to connect the DIGITAL (COAXIAL) INPUT and OUTPUT RCA connectors of the tape deck to other digital audio equipment. 1.4.1 Head cleaning Never attempt to clean the head of a DAT deck in the same way that you clean the head of an analog tape deck. Always use a special DAT head cleaning cassette. Follow the instructions on the cleaning cassette for optimum performance. The head may need to be cleaned if you hear errors (noise) on playback or while recording. You can make a visual check of the error rates and error locations using the DISPLAY [23] key or the error display menu (3.15, "Viewing points at which block errors have occurred"). NOTE The use of analog cables is not recommended for digital audio use, and TASCAM cannot guarantee reliable performance if such cables are used for digital audio connections. 1.5.4 Making control connections The optional RC-D45 remote control unit may be connected to the REMOTE IN jack, using the 5 m (approximately 16 ft) cable of the RC-D45. TASCAM DA-40 7 1 - Introduction to the DA-40 WARNING Do not attempt to use the tape deck with any remote control unit except one designed especially for use with this tape deck. The CONTROL I/O connector is for use with suitably-equipped control units (see CONTROL I/O [34]). 1.5.5 Power connections Make sure that your AC voltage supply matches the voltage requirements of the tape deck (as printed on the rear panel). 1.6 Block Diagram TASCAM DA-40 8 Front and Rear panels Front and Rear panels 9 TASCAM DA-40 2 - Parts of the tape deck NOTES As well as providing details of the settings made with switches, etc., this section also provides the information necessary for basic operations of the tape deck. Although the operation of the transport keys, etc. will be familiar, there are some additional features of this tape deck, and the operation of these features may differ slightly from the way in which they are implemented on other units. Please consult 2.3, "Tape controls" for full details of such features and their operation. The operation of the optional RC-D45 remote control unit is explained in 5, "RC-D45 remote control unit (option)". The more commonly-used functions of the function keys (below the display) which are labeled in white above the keys are also described in this section. The less commonlyused functions, labeled in blue above the keys, are described in 4, "SHIFT functions". Above the tape counter in the display are two bargraph peak level meters which show either the level of the input signals, or the level of the signals recorded on tape, depending on the current status of the transport. Other indicators in the display provide information on the current status of the tape deck and of the tape (e.g. sampling frequency, repeat status, and the various IDs encountered when a tape is being replayed). NOTE In this manual, we use the term "program" to describe part of a recording between two START IDs. This is equivalent to the term "track" on a CD or MD. Since the term "track" is already established with another meaning in analog tape recording technology, the term "program" is used here instead. 2.2 Recording mode and source switches, etc. The following controls affect the recording mode, and the selection of the signal source when making recordings. 2.1 Power and display [1] POWER switch Push once to turn the power on, and again to turn the power off. [4] RECORD MODE switch Use the switch to select between LP (long play) and SP (standard play). In standard play mode, the sampling frequency is as selected with the FS switch below. In long play mode, the sampling frequency is fixed at 32 kHz. In the long play mode, the tape speed is halved, meaning that a tape labeled as a 90minute tape will therefore provide 180 minutes of recording time. [2] Cassette tray and OPEN/CLOSE button Always load DAT cassettes in the way illustrated on page 7. Press the open/close button to open the tray. If a cassette is already loaded, it will be unthreaded, and the words Tray Open! will flash on the display. After the tray is fully open, these words will be shown (not flashing). When the tray is open, and the open/close button is pressed, the words Tray Close will flash on the display. If a tape is correctly inserted in the tray when it is closed, the display will show a counter value. NOTES If you are using a tape that has already been recorded in one mode, and you are making a recording using another mode, we suggest that you record the whole tape in the new mode, with no input signal, before making the audio recording. Recording in long play mode is only possible from analog sources, or if the digital source has already been recorded at 32 kHz. No setting is necessary to select the mode for playback-- the tape deck recognizes the mode in which the tape was recorded, and adjusts itself accordingly. [3] Display window The different modes available for display are described more fully below (COUNTER MODE [20] and DISPLAY [23]). 10 TASCAM DA-40 2 - Parts of the tape deck [5] Fs switch Use this switch to select the sampling frequency (44.1 or 48 kHz) when making analog recordings. When making digital recordings, the sampling frequency is automatically detected. When playing back tapes that have already been recorded, this switch has no effect. The sampling frequency of a recorded tape is fixed, and cannot be changed. +4 dBu or the ­10 dBV level as a nominal level. The input level controls are not used in this case. NOTE If this switch is set to the CAL position, make sure that no parts of the program material will cause clipping. [9] INPUT level controls When recording from analog sources with the ANALOG INPUT switch [8] set to UNCAL, these controls adjust the level of the input signal to the left and right tape tracks. They have no effect when the switch is set to the CAL position, or when recording from a digital audio source. NOTE When making long play recordings, settings made with this switch have no effect. The sampling frequency is fixed at 32 kHz. [6] INPUT selector switch The left (UNBAL) and center (BAL) positions of this switch allow the selection between the unbalanced RCA jacks or the balanced XLR jacks respectively. The right (DIGITAL) position allows the selection of the digital input jacks. [10] PHONES control and jack Any standard pair of stereo headphones may be plugged into this 1/4-inch jack, and the level adjusted with the rotary control. 2.3 Tape controls The following keys provide control of the tape transport, recording modes, etc. Please read this section carefully if you are not sure of transport operations using the tape deck. [7] DIGITAL INPUT selector switch When the INPUT switch [6] is set to the DIGITAL position, this switch is used to choose between the RCA COAXIAL and the XLR AES/EBU digital audio input sources. [11] SKIP keys NOTE Despite the name of the switch setting and the connectors (AES/EBU), the XLR connectors are capable of receiving SPDIF format input, and the RCA COAXIAL connectors are capable of receiving AES/EBU format. The tape deck will automatically detect the input format and adjust itself accordingly. These keys are used to move the tape forward or backward by a certain number of programs. NOTE A "program" on a DAT cassette starts with a START ID marker. The audio portion of the data recorded on a DAT cassette is not used to determine the division into tracks. Repeated presses of these keys will move the tape forwards or backwards by the appropriate number of programs (pressing the skip forward key once will move the tape to the beginning of the next program, etc.). While the tape is locating, the display will show (flashing on the right) the number of programs which must still be passed, and (on the left) the current program number: PNO ABS [8] ANALOG INPUT selector switch When the INPUT switch [6] is set to ANALOG, this switch is used to select between UNCAL and CAL. UNCAL means that the analog signal source works at an uncalibrated nominal level which is neither +4 dBu nor ­10 dV, requiring the use of the input level controls to adjust the recording level. The CAL position is for use with analog sources which are calibrated to use either the standard 0 0H 1 2M 4 6S 0 8 + 0 2 TASCAM DA-40 11 2 - Parts of the tape deck In the above example, the tape is currently on program 8, and must move two programs forward before the correct program (i.e. program 10) is reached. The flashing number on the right of the display should be used as the definitive indication of how many programs will be skipped (if the SKIP keys are pressed too quickly, it is possible that some of the key presses will not be recognized). When the start of the desired program is reached, the tape deck will enter the play mode if the tape was playing before the skip operation, otherwise it will enter pause mode. If the REC indicator is lit together with the PLAY indicator, the unit is recording. If the tape is locating as the result of a command to search for the beginning of a program (skip or program play), and the unit was in play mode before this search operation started, the PLAY indicator will flash, showing that the unit is in "auto play" mode, and playback will restart when the location is reached. [15] PAUSE key Use this key to put the tape deck into pause mode, as explained below. If the tape is stopped or playing, pressing the PAUSE key will put the tape deck into paused play mode (the PLAY and PAUSE indicators will both light). If the tape deck is in "input monitor" mode (see [16] below), pressing and holding down the RECORD key and pressing the PAUSE key will put the tape deck into record ready mode (the PAUSE and RECORD indicators will both light). From the record ready mode, pressing the PLAY key will start recording (the PLAY and RECORD indicators will both light). If the tape deck is left in pause mode for some time (three minutes or so), it will drop back into stop mode. [12] REW and F FWD keys Use these keys to wind backwards or forwards fast through the tape. If the tape is stopped or paused, and one of these keys is pressed, << or >> will be shown on the right of the display to indicate the direction of the tape movement, if the margin is being displayed (see DISPLAY [23]). If normal mode has been selected (3.12, "Fast forward mode"), pressing either of these keys when the tape is playing will start fast forward or rewind. If the tape is playing when one of these keys is pressed, and cue mode has been selected (3.12, "Fast forward mode"), the tape enters a "cue" or "review" mode, in which the tape is played forward or backward at twice or four times normal speed . The cue/ review speed can be changed by pressing the REW or F FWD key again, and is shown on the display as >>2/>>4 (cue), <<2/<<4 (review). [16] RECORD key Use this key for recording, as described here. Press this key once to enter the "input monitor" mode. In this mode, the display gives information about the current status of the tape deck and the connections, ensuring that clock signals, digital audio connections, etc. are properly made before recording starts. If all clock connections are in order, the display will show ANALOG in, AES/EBU or COAXIAL. The peak level meters will show the signal levels received through the selected inputs. In the case of the latter two digital options, the sampling frequency (either 32, 44 or 48) will be shown. If a digital input source is selected, and the sampling frequency of the received signal is outside the allowable range (± 0.1%) the display will show the signal source (AES/EBU or COAXIAL), followed by a question mark. Input monitoring is possible, but recording is not possible. [13] STOP key Use this key to stop the transport from whatever mode is currently selected. This includes the "input monitor" mode (see [16] below). [14] PLAY key Use this key to start playing when the tape is stopped or paused, or to start recording when the tape is in record pause mode (see below). The indicator above the key will light when the tape is playing back. In this case, the indicator will be the only transport indicator lit. The indicator may also be lit in combination with the PAUSE indicator, showing that the unit will enter playback mode almost instantly when the PLAY key is pressed. 12 TASCAM DA-40 2 - Parts of the tape deck If the selected digital input is interrupted or is incorrect for any reason, the words DIGITAL IN, shown on the bottom right of the display will blink to alert you of the fact. From the input monitor mode, pressing and holding the RECORD key and pressing the PLAY key will start recording (the RECORD and PLAY indicators will both light). From the input monitor mode, pressing and holding the RECORD key and pressing the PAUSE key will put the tape deck into record ready mode (the RECORD and PAUSE indicators will both light). [17] REC MUTE key Use this key to record a period of silence on the tape. If the tape deck is recording, and this key is pressed, the RECORD indicator will flash, and all input to the tape will be muted. After a number of seconds (defined in the menu RecMut function--see 3.4, "Record mute time"), the tape deck will enter the record ready mode (the record and pause indicators will both be lit). Pressing and holding the key for a few seconds will mute the input, and will put the tape deck into record ready mode as soon as the key is released. [18] SHUTTLE wheel NOTES If the tape deck is left in record ready mode for three minutes or longer, it will automatically enter the input monitor mode (the head drum will stop spinning). It is possible to enter input monitor mode with a write-protected cassette inserted, or with no cassette inserted. It is also possible to enter the record mode directly from the stop mode by pressing and holding the RECORD key and pr\essing the PLAY key. It is also possible to enter the record ready mode directly from the stop mode (RECORD key and PAUSE key). When the tape deck is in record ready mode, when recording on a tape which has previously been recorded or "formatted" by recording silence, turning the DATA dial [19] allows the selection of a program number other than 01, meaning that this recording will start at the selected number, and subsequent programs will be written with numbers automatically incremented from this selected value. Turn this wheel to move the tape backwards (counterclockwise) or forwards (clockwise). Turning the wheel further from the center will make the tape move faster in the appropriate direction. The tape may be shuttled both forwards and backwards, from normal speed to twelve times normal speed . When entering characters for program titles, and editing memory locations, etc., this control acts as a cursor control (counterclockwise to move the cursor to the left, and clockwise to move it to the right). [19] DATA dial This dial is used for two major functions. One is to change the value of data in menus and parameter settings. It can also be used, however, to select an absolute program number at which playback should start (compare this with the SKIP keys, which are used to select a program number relative to the current number). While the tape is stopped or paused, and a menu or edit function is not displayed, turn the data dial. PNO ABS NOTE Valid program numbers are from 01 to 99. If the above procedure is used to select a program number at the high end of the range, and the automatic increment procedure takes the number above 99, the number will "wrap" to 00. The number 00 can cause problems when searching and locating, and this should be remembered when setting program numbers. 0 0H 0 3M 0 8S 0 2 > 0 4 The program number following the > sign flashes. Program numbers can be from 01 through 99, and turning the DATA dial past the limit will start at the other end of the list. Press the PLAY key within five seconds of turning the DATA dial to locate to the start of the program and start playing. Press the PAUSE key within five seconds of turning the DATA dial to locate to the start of the program and put the tape deck into pause mode. TASCAM DA-40 13 2 - Parts of the tape deck NOTE If the DATA dial is turned by mistake, either leave the tape deck alone for five seconds to cancel the operation, or press the STOP key. minutes. Bear this in mind when you are using the LP mode. · Tape Counter mode-- no indication is given on the display of the mode, and a 4-digit number is used to show the tape position. This value is relative to a user-definable reference "zero" point (see MARGIN RESET [22]). PNO MARG 2.4 Command keys These command keys have two modes: the primary mode, labeled in white above the key, is the most common use for the key. The secondary, or shifted, mode is labeled in blue above the key, and is only operative when the SHIFT indicator [31] is lit (see 4, "SHIFT functions" for details of these secondary modes). 01 26 0 8 6. 3 dB [21] CHAR If characters have been recorded on the tape as a tape or program title, pressing this key will allow the tape deck to display these characters, scrolling across the display, as the START ID containing the title is played back. They will be replaced by successive title contents as they are read from tape. If characters are read from a START ID, the CHAR indicator will light in the display to indicate this. If no characters have been recorded on the tape, pressing this key will have no effect. [20] COUNTER MODE Use this key to cycle through the different tape counter modes available: · ABS time-- the absolute time as recorded on the subcode of the tape. This is expressed in hours, minutes and seconds. If the tape is at an unrecorded location, the tape counter will show all dashes. PNO ABS MARG [22] MARGIN RESET Pressing this key resets the margin (available headroom) to its lowest level of 40dB. Note that in some display modes, there is no visible effect when this key is pressed. The margin is measured in 1 dB increments between 40 dB and 20 dB and in 0.1 dB increments between 19.9 dB and 0 dB. If the time display is in the 4-digit tape counter mode, pressing this key will reset the tape counter. 0 0H 2 6M 3 5S 0 9 6. 3 dB · PGM time-- the elapsed time since the last START ID which has been read from tape (the beginning of the program). If, when the display is in this mode, the tape is located to a point outside a START ID and playback restarts, the tape deck will be unable to determine the time since the start of the program and the display will show all dashes instead of a time value. PNO PGM MARG [23] DISPLAY Regardless of the current counter mode set by [20], this key is used to display other information. The options available, which are accessed by repeated presses of this key, are: · Program number and Margin mode-- where the current program number and margin in decibels are displayed: PNO ABS MARG 0 3M 1 7S 0 9 6. 3 dB · REMAIN time-- the time remaining on the currently-loaded cassette; to minute accuracy. Cassettes from different manufacturers may vary slightly in length, resulting in different values being shown for tapes which are nominally the same length. PNO REMAIN0 MARG 0 0 3M 0 9 6. 3 0 0H 2 3M 0 8S 0 7 6. 3 dB dB NOTE In LP mode, the counter shows one second of tape time for every second of real time in the ABS, PGM and REMAIN counter modes. For example, after one hour's playback or recording in LP mode, the counter will only show 30 · Frames mode-- where frames are displayed as well as hours, minutes, and seconds. The frames used are "digital audio" frames, i.e. there are 100 frames in every three seconds; 33 in the first second, 33 in the next, and 34 in the third. The pattern then repeats itself.

When playback starts, the error rate for either the A or B track is displayed. The A or B track is selected using the MENU key while the error rate display mode is active. ABS [26] ENTER This key is used to confirm entries made in the menu and EDIT settings. It is also used, when in EDIT mode (see 4, "SHIFT functions"), to enter the EDIT functions). When recording subcode (START, SKIP, END IDs and CHAR title information), it is used to start the writing of this information to tape. 0 0H 2 3M 0 8S A 0 0 1 7 · If titles have been recorded on the tape (see 4.8, "Character editing (titling)"), CHAR is shown on the display, and the characters comprising the title are shown on the display (here, the word "TASCAM" is used as the title): ABS [27] MENU Repeated presses of this key (when the display is not in Block Error mode) cycle through the different options available in the menu. These options are explained in detail in 3, "Menu functions". 0 0H 2 3M 0 8S T A S C A. M [24] SKIP PLAY When skip mode is active, SKIP PLAY is shown on the display. Skip mode means at that when a SKIP ID is encountered on tape, the tape will fast forward until the next START ID is encountered. [28] LOC 1 Pressing this key will locate the tape to the first memory location (set with this key in shifted mode). If the tape is playing when this key is pressed, the tape will resume playing when the location is reached, otherwise it will stop. When the key is pressed, the value stored in the first location memory will flash on the right side of the display (frames, program numbers and margin will disappear while the tape is locating, and be restored once location is complete). If a pre-roll time has been set in the menu, pressing this key will locate to the memory location minus the pre-roll time. When search or locate is entered from the tape stopped or in play pause mode, and the PLAY key is pressed while the search or locate operation is taking place, deferred playback will occur when the location point is reached. However, if the PLAY key is pressed when the tape is close to its final operation, you should note that there may be a problem with the deferred playback. [25] AUTO ID When AUTO ID mode is active, AUTO ID is shown on the display (see 4.4, "ID markers (START, SKIP, END, CHAR and renumbering)" if you are unsure about ID marker types). This means that when recording, a START ID will automatically be written when a "trigger level" signal is detected after a period of silence. The number of the new START ID is one greater than the last ID successfully read from tape. However, the automatic numbering of IDs will be out of sequence if a START ID is added between existing IDs, or if an ID is written before a valid previously-recorded START ID has been read from tape. Use the renumber function to restore the sequence. See 4.4, "ID markers (START, SKIP, END, CHAR and renumbering)". The level which will trigger the automatic writing of a START ID, and the length of the silence to precede it may be set from the menu items (see 3.2, "Auto ID level" and 3.3, "Auto ID time"). When you use the AUTO ID key to turn on the auto ID mode, these values (the level and time) will be shown for one second on the display. For example, the display may show AT-ID 48/2.0, meaning that the trigger level is set to ­48 dB and the length of the preceding silence is set to 2.0 seconds. [29] LOC 2 This key functions in exactly the same way asLOC 1 [28] above, except that the second location memory is used rather than the first. [30] SINGLE PLAY The single play mode, when active, will play only one program , i.e. when the next START ID is encountered, playback will stop. When single play mode is active, the display will show SINGLE PLAY. TASCAM DA-40 15 2 - Parts of the tape deck Direction [31] SHIFT This key is a latching key. When active, the indicator beside and above the key lights, and the command keys take on their shifted functions, as indicated by the blue captions above them.

The nominal impedance of these connectors is less than 10 k. The trimmer beside each connector can be used to reduce the output level to match the level expected by the equipment connected to the tape deck. The "standard" setting (and the condition in which the unit is shipped from the factory) is with these trimmers set to maximum (fully clockwise). TASCAM DA-40 17 3 - Menu functions The menu facilities on the tape deck allow common settings to be made. Repeated presses of MENU [27] will cycle through the different menu items listed here in the order presented here. Repeated presses of the DISPLAY [23] key when the tape deck is in menu mode will display the different menu items in the opposite order to the one in which they are presented here. The options available are: -48dB, -54dB, -57dB -60dBand dd. The dd setting detects the digital start of a track. When the dd setting is made, and if a DAT deck is connected to the tape deck through the COAXIAL interface, the START IDs and SKIP IDs on the source deck are transferred over the coaxial connection and recorded on the tape deck. If a CD player is connected with dd set, when the start of a track is read, a START ID is written on the tape deck. Note that if an analog connection is made between the tape deck and a CD or DAT recorder, and recording is carried out through the analog connections, if dd has been selected, the Auto ID level is automatically set to -54dB. This is also the case if a digital device other than a DAT recorder or a CD player is attached to the tape deck. NOTE When attempting to access the menus with the MENU key, the display mode should not be the Block Error rate display mode. In this display mode, pressing the MENU key changes between the A and B tracks. When setting values from a menu, turn the DATA dial [19] to change the displayed value. The new value will be shown flashing on the display. Press ENTER [26] to confirm the value. If the DATA dial is turned, but no changes are to be made to the displayed value, press the MENU key again to return the display to the previous value. To exit the menu mode, press either the COUNTER MODE [20] or the MARGIN RESET [22] key. NOTES CD tracks of less than 18 seconds may not have their corresponding START IDs recorded properly. In order to ensure accurate program searching, a gap of at least 9 seconds should be left between the end of one START ID and the beginning of the next. The default value for this menu is -48dB. 3.1 Drum time (head time) Drum-T 0 0 1 0 H 3.3 Auto ID time AtID-T2 . 0 s e c Reports the time (in hours) that the head drum has been in use. Use this information to help schedule head cleaning, following the interval between cleanings as recommended by the cleaning cassette. 3.2 Auto ID level AtID-L 4 8 d B When the AUTO ID function is enabled (AUTO ID [25]), signals which exceed the level set in 3.2, "Auto ID level" will automatically start the recording of a START ID, if the signal has remained below the level for the period set in this parameter immediately before exceeding the trigger level. Since the tape deck does not read track numbers, etc., from digital audio sources, this function should be used to divide CD tracks and assign new program numbers at the start of each track. Set the "gap time" as appropriate for the program material. The times available are: 2.0, 2.5, 3.0, 0.5, 1.0 and 1.5 seconds. The default value is 2.0 seconds. When the AUTO ID function is enabled (AUTO ID [25]), signals which exceed this level, after a period of relative silence (as set in 3.3, "Auto ID time") will automatically start the recording of a START ID at the point where the signal exceeds this level. 18 TASCAM DA-40 3 - Menu functions 3.4 Record mute time RecMut 2 s e c (one generation only of digital copying is possible from tapes produced when this setting is made), and Prohbt (no digital copying at all is possible). The second option is equivalent to the SCMS system implemented on consumer DAT recorders. The default value here is Free. Sets the length of the silent period when the REC MUTE key [17] is pressed, the input signal to the tape is muted, and a period of silence is recorded. The values available are: 4, 5, 6, 7, 2 and 3 seconds. The default value is 4 seconds. 3.7 End ID End-ID N o W R NOTE The time set here is real time, rather than the time shown on the tape counter, which in LP mode is half that of real time. Accordingly, in LP mode, if the time is set to 4 seconds, this will be the record mute time, even though only 2 seconds show on the tape counter. Sets whether an END ID is automatically written whenever recording stops. The two options available are: No WR (no END ID is written when recording stops) and AutoWR (an END ID is automatically written when recording stops). When an END ID is written, the display shows WR-EE. When playing back and an END ID is encountered, EE is shown on the display, and playback stops. The 3.5 Digital output format Format A E S E BU tape then either stops or rewinds, depending on the setting made in 3.11, "Auto rewind". The default value is No WR. Sets the format of the digital audio data output from both digital audio outputs (the AES/EBU XLR connector and the COAXIAL RCA connector). The options available are AESEBU (AES/EBU31992) format) and Consmr (IEC60958 format). 3.8 Repeat mode Repeat 1 0 T M S This menu item controls the number of times that the playback will repeat when the repeat mode is set (see 4.1, "REPEAT"). The options available are: 10TMS (the playback will repeat 10 times) and UnLimt (the playback will repeat indefinitely until stopped). The default value is 10TMS. NOTE Regardless of this setting, in input monitor mode, record pause or record mode, the tape deck will output in the same format as the digital audio signal received at the input. The default is AESEBU. 3.9 Pre-roll time PreRol 0 s e c 3.6 Copy prohibit Sets the level of copy protection for tapes recorded using this tape deck. CopyID F r e e The menu items control the writing of the copy protection bit in the subcode of the recorded material.

The setting made here has no effect on locating to the START IDs of programs using the SKIP keys [11] or the DATA dial [19]. The values available are: 0, 1, 2, 3, 4 and 5 seconds. TASCAM DA-40 19 3 - Menu functions NOTE The time set here is real time, rather than the time shown on the tape counter, which in LP mode is half that of real time. Accordingly, in LP mode, if the time is set to 4 seconds, this will be the pre-roll time, even though only 2 seconds show on the tape counter. The default value is 0 seconds. (the unit will enter cue/review mode when the fast wind keys are pressed). The setting made here also applies to fast wind commands made through the CONTROL I/O [34] connector, and using the optional RC-D45 remote control unit. The default value is Normal. 3.13Parameter save P-Mode - 3.10End tally signal EndTLY T E n d Controls the timing of the tape end tally signal transmitted through the CONTROL I/O [34] port. The signal can either be transmitted at the end of the tape, or at a fixed interval before the tape end. The values available are: T-End (the tally signal will be transmitted at the end of the tape), 1min, 2min and 3min (the tally signal will be transmitted before the end of the tape is reached). The default value is T-End. Saves the following parameters so that they become the default parameters when the tape deck is next powered up: · Single Play · Skip Play · Repeat Mode When this menu item is first displayed, the right side of the display shows: ----. To save the current settings, turn the DATA dial [19], so that the display shows Save, and press ENTER [26]. 3.14Initializing settings *Data* - 3.11Auto rewind At-Rew o f f This menu item determines whether the tape will be automatically rewound when the end of the tape or an END ID is reached in play mode.
