All major surround formats are supported, from LCRS to 7.1. Providing flexible switching and routing facilities between a digital recording console such as the TASCAM DM-24 and digital multitrack (tracking) recorders as well as the multitrack recorder being used to master the surround mix (the stem recorder), the DS-M7.1 can be used for monitoring of the mix as it comes off the console, as well as the recorded mix from the mastering recorder, with the push of one front panel key. Surround Monitoring System DS-M7.1 Output Router Out Insert Device (e.g. Surround Encoder/Decoder) In Input Summing Router In Tracking Recorder TRK Recorder I/O BUS/ RTN Master Recorder I/O Out Mastering Recorder In Out Console I/O Note that mastered tracks (with or without Insert) are monitored as RTN. Inputs from the console are monitored as BUS Recorder Returns Buss Outputs Digital Mixing Console The signals are switched and routed in the digital domain, allowing the highest possible quality to be maintained throughout the system. Monitoring signals are output in both digital and analog format, and either can be selected as best suits the needs of the facility in which the DS-M7.1 is installed. Downmixing is an important part of the surround mix process, and the DS-M7.1 allows the operator to select from a very wide range of downmix options and settings. Bass management for monitoring comparisons with consumer-oriented systems which lack a dicrete LFE channel is well supported, with user-selectable crossover and level settings, etc. Connections are made using industry-standard cables, and the slots for up to three optional TASCAM expansion cards provide great flexibility, TASCAM DS-M7.1 5 1 ­ About the unit allowing almost every common industry format to be supported by the DS-M7.1. Full calibration facilities are provided, with a built-in pink noise generator, to allow for quick, easy and accurate setup of the unit. Channel delay is provided to compensate for acoustic delay when surround speakers are used in a large space. An analog or digital insert can be placed in the monitoring path, in order to hear the surround mix through a surround encoder. This is useful for hearing the effect of the encoding process. Muting and soloing of individual channels, with flexible soloing options, allows checking of any desired combination of surround channels. SPL indication and control is available from the front panel, allowing the surround monitoring to be carried out accurately, according to the different guidelines and standards within the industry. A dedicated pair of analog stereo inputs can be fed from the console's main control room outputs, allowing the same speaker/amplifier system to be used for the L and R channels in both surround and stereo operation modes. The last pair of the surround speakers (channels 7 and 8) can also be dedicated as smallalternative stereo speakers when the primary surround application is 5.1 or LCRS. For flexibility, the front panel controls can be removed and connected to the main unit in the machine room, allowing full control to be maintained from the listening position. The unit itself is simple and easy to use, taking advantage of a menu-driven 20x4 alphanumeric display and rotary encoder system, with important mode keys illuminated for quick verification of their status. This manual accompanies the unit, together with a Setup Guide, which should be used when you are first setting up and calibrating the unit. For best results we recommend that you follow these procedures regarding level and delay adjustment whenever you make a substantial change to your monitoring environment. Installing the DS-M7.1 When you unpack the DS-M7.1, you should find, in addition to this manual: · A rack-mounting kit · A standard power cable whose plug should match the one for your region. · A Setup Guide · Warranty information, etc. If any of these is missing, contact your TASCAM distributor. The DS-M7.1 is designed to fit into 3U of standard 19" rack space. Remove the feet before installing it in a rack. We suggest that you leave at least 1U of space above the unit to allow for cooling. Always check that the power requirements printed on the rear panel of the unit match those available in your working environment. If they do not, or if you are in any doubt, consult a qualified electrician. Do not install the unit in an enclosed space (bookcase, etc.). Temperature considerations The ambient operating temperature should be between 5°C and 40°C (41°F and 104°F). Connections All connections to and from the DSM7.1 should be made and broken with the power turned OFF. 6 TASCAM DS-M7.1 1 ­ About the unit Using the front panel as a remote control unit When you use the front panel as a remote control unit, you have the choice of using either the front or rear 9-pin D-sub connector. If the DS-M7.1 is to be installed in a machine room some distance from the mixing location, we suggest using the rear connector, where the cable may be routed more conveniently. Follow the instructions given here ("Making up a remote control cable" on page 38) when making up a cable for use with the remote control. If you do not follow these instructions, there is a risk of incorrect operation, or even damage to the unit. TASCAM DS-M7.1 7 2 ­ Parts of the DS-M7.1 Front panel The part of the front panel of the unit which houses the display and controls can be removed and connected via an appropriate cable, up to 20m (60ft.) in length by turning the captive thumbscrews at the top of the panel counterclockwise. Retaining lug on main unit front panel Retaining hole in removable front panel Note that the front panel is retained by the thumbscrews, and when it is removed from or replaced on the main unit, care must be taken to match the retaining hole on the front panel with the retaining lug on the main unit, as shown here: When removed in this way, the front panel can be used as a remote control unit, with the main unit located in the machine room of the studio facility, together with the multitrack and mixdown recorders.

See "Word clock errors" on page 15. 8 TASCAM DS-M7.1 2 ­ Parts of the DS-M7.1 Function keys These keys all have two functions: the unshifted function, as shown by the label above the keys, and the color-coded (to match the SHIFT key) shifted function, as shown by the lower label. The shifted function is enabled when the SHIFT indicator is lit. A VALUE Use this rotary encoder to set the values shown on the display. B CURSOR keys Use these keys to navigate between the parameters shown on the display. 4 STATUS/INPUT The STATUS key brings up the Status screen, where the settings relating to the master status of the system can be viewed (but not changed). As the INPUT key, it is used to route and assign the inputs. C MUTE CONTROL keys and indicators These correspond to the channels of the different surround formats supported by the DSM7.1. When a surround format is selected, the indicators of those channels which are valid for the format are lit. For example, if 5.1 is selected, the L, C, R, LS, RS and LFE indicators are lit. The keys act as monitor mute keys or solo keys (depending on the status of the SOLO/MUTE key, and are also used for selecting channels when setting up the relative levels of the channels (see the Setup Guide for details). 5 SYSTEM/OUTPUT As the SYSTEM key, system settings are made on the screen brought up by pressing this key. As the OUTPUT key, it enables assignment of the monitor outputs to the channels of the selected surround format. D ALT SPK Pressing this key selects speakers connected to the LC and RC channels. When in surround mode, pressing this key automatically performs an LR downmix to the LC and RC channels. 6 INSERT/DELAY The DS-M7.1 allows either an analog or digital insert loop in the monitoring path. Use the INSERT key to control this insert. In shifted mode, the DELAY key is used to compensate for speaker placement. See the Setup Guide for details. E SPL REFERENCE indicator and LEVEL control Use these to set and view the SPL level output by the DS-M7.1 when it is properly calibrated. See the Setup Guide for full details of its operation and its relationship to the software SPL setting. NOTE 7 DOWNMIX/TRIM Downmixing refers to the practice of monitoring a surround mix "folded down" to a format with fewer channels, in order to check mix compatibility. The DS-M7.1 allows you, for example, to hear how a 5.1 mix will sound when played through a 2-speaker stereo system. Use this to set up the downmix parameters. As the shifted TRIM key, this key is used to set up the relative levels of the surround channels. See the Setup Guide for details. If the output level is adjusted with this control so that it exceeds the level set in the LCD menu (see the Setup Guide), there is a risk of clipping and degradation of sound quality. F SOLO/MUTE Switches the function of the MUTE CONTROL keys between muting and soloing 8 BASS MGT/TEST Used to select the type of Bass Management used, and to set up the subwoofer crossover frequency, relative level, etc. for when bass management is enabled (see "Bass management" on page 21). As the shifted TEST key, it is used to set up the pink noise parameters for level testing. See the Setup Guide for details. (the type of solo mode, exclusive or mix, is userselectable). G SRND/ST Switches easily between the selected surround format from the CONSOLE or MASTER I/O connectors and stereo (input from the dedicated CR stereo inputs on the rear panel). H BUS/RTN Switches monitoring between the bus inputs (from the mixing console--the indicator is unlit) and the return inputs (from the mixdown recorder--the indicator is lit). The default as shipped from the factory is bus (the indicator is unlit). 9 SHIFT key and indicator This latching shift key alters the behavior of the function keys listed above. It also is used with the DOWN MIX key for mono downmixing. TASCAM DS-M7.1 9 2 ­ Parts of the DS-M7.1 I TEST Used in setup to turn the internal pink noise generator on and off. See the Setup Guide for details. K BASS MGT Turns the bass management function on and off (settings are made with the BASS MGT function key) L MUTE ALL Cuts all the monitor signals simultaneously. J DOWN MIX/MONO Switches between the selected surround format and the currently-selected downmix mode (the downmix mode is selected using the SYSTEM function key). When pressed together with the SHIFT key, this key downmixes directly to mono from any surround format. M DIM Reduces the monitor output by a softwareselectable amount. The default value, as shipped from the factory, is an attenuation of ­20dB. 10 TASCAM DS-M7.1 2 ­ Parts of the DS-M7.1 Rear panel See the section on Connections for details of how to make connections to and from the DS-M7.1. 1 2 347 8 9 AB C 5 6 NOTE 1 Expansion slots The DS-M7.1 is fitted with three expansion slots, which can take different types of I/O card. Consult your TASCAM dealer for details concerning the availability and the fitting of these cards. When a card is fitted, it can be used as an alternative to one of the three connectors immediately to the right of the slots, as described below. NOTE When making connections to the DS-M7.1 using the AES/EBU connectors, note that channels 1 and 2 must always contain some signal. If there is no signal in these two channels, no other AES/EBU channels can be received. Also note that if the preamble is not correctly received on a pair of AES/EBU input channels, those channels will be muted. Although an analog IF-AN/DM card may be fitted in any slot, only one such card may be fitted at a time. 5 MONITOR OUTPUTS There are two sets of monitor outputs, which work in parallel, providing up to eight channels of surround monitor outputs apiece. Both are output from 25-pin D-sub connectors and require appropriate "breakout" cables (consult your dealer for details). The ANALOG connectors work as balanced +4dBu outputs, while the AES/EBU connector provides digital audio in AES/EBU format. 2 SLOT 1/CONSOLE I/O (TDIF) This 25pin D-sub connector sends and receives up to eight channels of digital audio in TDIF format to and from a suitably-equipped digital mixing console such as the TASCAM DM-24. If a card is fitted in slot 1, it may be used as an alternative to this connector. 3 SLOT 2/TRK RECORDER I/O (TDIF) This 25-pin D-sub connector sends and receives up to eight channels of digital audio in TDIF format to and from a suitably-equipped multitrack recorder, such as the TASCAM DTRS series, or MX-2424 recorders. If a card is fitted in slot 2, it may be used as an alternative to this connector. 6 STEREO CR INPUT These balanced +4dBu inputs allow the stereo CR outputs from a mixing console to be fed into the DS-M7.1, allowing the same amplifier/speaker monitoring system to be used for surround and stereo monitoring, without repatching. NOTE 4 SLOT 3/INSERT I/O (AES/EBU) This 25-pin D-sub connector sends and receives eight channels of digital audio in AES/EBU format. It can be used for inserting a surround encoder/decoder in the monitoring path. If a card is fitted in slot 3, it may be used as an alternative to this connector. Note the relationship between analog and digital signal levels on the DS-M7.1. The maximum analog level is +24dBu, equivalent to 0 dBFS digital. The nominal level is +4dBU, corresponding to a digital level of ­20dBFS. 7 WORD IN Use this BNC connector to receive an external word clock signal. The 75 switch allows termination to be set ON or OFF (usually ON). TASCAM DS-M7.1 11 2 ­ Parts of the DS-M7.1 8 MASTER RECORDER I/O There are three sets of connectors for connecting the master recorder: TDIF-1 (combined input and output), ADAT (separate input and output "lightpipe" connectors) and AES/EBU (combined input and output). nect tip to sleeve for the mute control, and ring to sleeve for the dimmer. Switches used in this way are active when closed, and should be non-latching. See "Dimmer and mute control connections" on page 18. C ~ IN (power input) Use the supplied power cord to connect the DS-M7.1 to the power supply. Ensure that the power supply is the correct voltage (as marked on the rear panel of the unit).

Con- Always connect and disconnect the power with the power switch on the front panel of the DS-M7.1 turned OFF. If the power cord is connected or disconnected with this switch on, there is a risk of damage to the unit. 12 TASCAM DS-M7.1 3 ­ Connections This section describes not only the connections you make between other equipment and the DS-M7.1, but also the software steps necessary to make that other equipment recognizable by and usable with the unit. Read this section carefully, especially the section on word clock, as it is essential to the proper operation of your system, and may even result in damage to your equipment if the appropriate steps are not carried out. NOTE Also note that while the TDIF and AES/EBU connectors on this unit are physically identical, the wiring and signals passed through them are very different. Take care to connect only TDIF equipment to TDIF connectors, and AES/EBU equipment to AES/EBU connectors, otherwise damage may occur to your equipment. If the use of cables other than TASCAM cables causes or results in damage, the warranty is voided. It is assumed that all necessary optional cards have been fitted to the DS-M7.1. See the diagram on page 5 as well as the block diagram ("Block diagram" on page 39) if you are unsure of signal flow within the DS-M7.1. Consult your TASCAM dealer for details of suitable approved cables that may be used when using your DS-M7.1 with other equipment. If you need an extension to the front panel cable to allow the front panel to be used as a remote control unit, see "Making up a remote control cable" on page 38. When making connections between the DS-M7.1 and other equipment, whether audio or control, both the DS-M7.1 and the other equipment must be turned off, otherwise damage may be caused to the DS-M7.1 and/ or the other equipment. Only use TASCAM-supplied and TASCAM-approved cables when making TDIF connections to the DS-M7.1. 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. Connecting the console The console can be connected to the built-in CONSOLE I/O connector, or to an optional card fitted in slot 1.

When this is done, the inputs and outputs must be routed appropriately, as described later. A note on the word clock Note that the DS-M7.1 cannot act as the word clock master in a digital system. It must therefore receive its word clock from a master clock elsewhere in the system, and this must be the only clock in the system. Use of more than one master clock in the system can lead to serious sound degradation, and possible damage to speakers and equipment. The word clock can be taken from either the dedicated WORD IN BNC connector, the console input (or the equivalent slot) or the master recorder (any of the three possible inputs). If the dedicated WORD IN connector is used, be sure to set the termination switch as determined by the needs of the rest of your system. 3 Since the word clock is important to correct operation, not only of the DS-M7.1, but of the whole audio system, an explanation of how to set up the word clock is given here. 1 If the word clock setting in memory does not correspond to the actual word clock connection physically present, the display will flash.

They may not be supported by other equipment, and you should check carefully in the documentation of all the components of your system to ensure that this is a valid option.

In this case, you may need to invert the polarity of the clock so that it syncs accurately with the other devices in the setup. 1 Press the SYSTEM key, and use the cursor keys until a screen similar to the following appears: [SYSTEM] LFEGain Solo WordIN +10dB Exlusiv e Normal <> 2 Normal Switch the WordIN parameter between and Reverse.

Check and correct settings on the clock master. Inserts Either analog or digital insert units can be connected to operate after the BUS/RTN switch. These are selectable pre- or post- the Input Summing Router. These inserts can be pre- or post- the input summing router (placed between the inputs and the RTN/BUS selector switch) and always pre- the RTN/BUS switch. See the block diagram at the end of this manual for details. Either AES/EBU digital devices, or analog (standard +4dBu balanced) may be used here. Note that when making connections to an analog insert unit, because of the nature of the connectors used, two connections need to be made, one for input and one for output. After the connection has been made, you should set up the insert as follows: 4 1 Press the INSERT key so that the screen shows something like: [INSERT] State Mode Return DISABLED POST SUM ANALOG 2 There are three parameters. Use the cursor keys to select them. First, select whether the insert loop is enabled (ENABLED) or disabled (DISABLED). Next, select the position of the insert loop, as described above: either PRE SUM or POST SUM (i.e. before or after the input summing router). Finally, set the Return type: ANALOG (analog) or DIGITAL (digital). 3 Monitor connections There are two sets of monitor connections, analog and digital. The analog connections are standard balanced +4dBu connections, and the digital outputs are in AES/EBU format. NOTE TIP The AES/EBU monitoring signals can be used in parallel with the analog monitoring signals to drive a suitablyequipped meter bridge. The sampling frequency output from the digital monitor outputs is the input frequency. If you are mixing a high sampling frequency project, you must therefore make sure that your digital monitoring setup can handle these frequencies, or use the DS-M7.1's analog monitoring ports. However, there is one setting that can be made for the AES/EBU digital ports; the "pick-off" point for the monitoring. This can be set so that all the downmix, bass management and delay settings, together with all muting and soloing and level settings described in "Other monitoring settings" on page 17, are ignored, or so that these settings take effect through the digital port. This affects the digital outputs only--the analog outputs will always reflect these settings. The analog and digital signals are output in parallel, and there is no switching between them. 16 TASCAM DS-M7.1 3 ­ Connections 1 Press the SYSTEM key, and use the cursor keys until a screen similar to the following appears: [SYSTEM] MonOut POST < 2 Use the VALUE control to select between POST (the digital signals mirror the analog signals) and PRE (the parameters described above are ignored). Other monitoring settings There are other system settings related to the monitor system, which affect the analog outputs and the digital outputs in "post" mode. These are the SPL Reference Level, the Dimmer level, the Surround level and the LFE Gain. Surround level This sets the amount by which the surround (rear speaker) level is attenuated. 1 Press the SYSTEM key, and use the cursor keys until a screen similar to the following appears: [SYSTEM] Dimmer SPLRefLevel SurroundLvl -60dB 82dB -10dB <> SPL Reference Level sets the reference value of the SPL which will be used in the monitoring environment. See the Setup Guide for details of how this works. It is accessed and set in the screen described here, however. 2 SurroundLvl Dimmer level This sets the amount by which the monitor signal is dimmed (or attenuated) when the DIM key is active. 1 Press the SYSTEM key, and use the cursor keys until a screen similar to the following appears: [SYSTEM] Dimmer SPLRefLevel SurroundLvl -60dB 82dB -10dB <> Use the VALUE control to set the parameter value to between 0dB and ­10dB in 1dB steps. LFE gain This refers to the amount of relative gain added to the LFE channel. 1 Press the SYSTEM key, and use the cursor keys until a screen similar to the following appears: [SYSTEM] LFEGain Solo WordIN +10dB Exclusive Normal <> 2 Use the VALUE control to set the Dimmer parameter value between ­60dB and ­10dB in 5dB steps. 2 Use the VALUE control to set the LFEGain parameter value to any of the following values: 0, +6, +7, +8, +9 or +10 (dB). Control room stereo inputs These balanced +4dB inputs are used for a direct feed of the master CR analog outputs (your console may give these a different name, but they are the stereo outputs used for monitoring in the control room) to the DS-M7.1. These outputs can be monitored directly from the DS-M7.1 using the SRND/ST key. Note that the stereo inputs are subject to the same downmix, delay, processing etc. as the surround inputs. See the block diagram for details. TASCAM DS-M7.1 17 3 ­ Connections Dimmer and mute control connections A remote box for mute (MUTE ALL) and dimmer control may be made up and used so that the control of these functions can be carried out from a location in the listening environment other than the main mixing location. Use non-latching push-to-make switches wired to a common sleeve ground with the dimmer wired to ring, and the mute to the tip of a standard 3.5mm stereo plug. The detection of the change in level, rather than the open/closed status of the switch triggers the change in the unit's status. A remote box fitted with these switches can operated alongside the appropriate front panel switches (it does not replace them).

Since project needs and applications vary, the DSM7.1 provides flexibility in the way in which incoming signals are received and monitored. Choosing the surround format First, you must decide in what format the incoming signals are to be processed. The available options are: 7.1, 6.1, 5.1, LCRS (LS, RS), LCRS (CS) and LR. These may be graphically represented in the following way (LR (stereo) is not shown, as it is assumed the reader is familiar with this format!): L LC C LFE RC R L C LFE R LS RS LS CS RS 7.1 format 6.1 format L C LFE R L C R LS RS LS CS RS 5.1 format L C R LCRS (LS,RS) format CS LCRS (CS) format Consult one of the standard reference works on the subject if you are unsure under which circumstances each format is used (a note on the two LCRS formats is given below). Note how the placement of the speakers relative to the listener is mirrored by that of the MUTE CONTROL keys of the DS-M7.1 (except in the 7.1 mode). To set the surround format and the routing of the inputs through the input summing router (you may want to consult the block diagram at this stage): TASCAM DS-M7.1 19 4 ­ Routing and patching 1 With the SHIFT indicator lit, press the STATUS/INPUT key so that the screen displays the following: [INPUT Format Input Output 1 SUM ROUTER] 12345678 *------LCRS(LS,RS) 2 Use the cursor keys to navigate to the set the value (VALUE control) to one of those listed above. Input parameter, and As you select the surround pattern, note how the green indicators under each MUTE CONTROL key light and go out, reflecting the surround pattern you have selected. A note on LCRS The DS-M7.1 supports two variants of the LCRS format to support a control room set up for 5.1 or 6.1 operation without the need to repatch the speakers. nal by 3dB and then assigning it to the LS and RS speakers. LCRS (LS, RS) In the first of these format, a "phantom" speaker is created by attenuating the LS(S) sig- LCRS (CS) This format assigns the LS(S) signal to the LC(CS) speaker. You should choose the appropriate LCRS format depending on your control room setup. Configuring the Input Summing Router You should now configure the Input Summing Router. This does not affect the physical output assignments made by the Output Router but will affect what goes to the insert in post mode. Since you may have more channels in the surround format you are mixing to than you do offboard insert equipment, you may need to combine more than one input with the Input Summing Router before sending the signals to an inserted device. The DS-M7.1 allows you to do this, in the following way. 1 On the bottom line of the screen above, move the cursor to the Output field, and use the to pick the desired Input Summing Router output. 2 Move the cursor to the bottom right of the screen, representing the eight inputs of the Input Summing Router, and use the cursor and VALUE control to assign (*) or release (-) an input to and from an output. When this is done, repeat the first step for the next Input Summing Router output. Note that this way of working allows an input channel to be assigned to more than one monitor output, and a monitor output to be fed by more than one input. Value control Matching output channels to surround channels The next stage is to match the numbered output of the Input Summing Router (as routed and summed earlier) to the named surround output channels of the surround pattern you have set up earlier. You may not need to do this if your setup matches standard settings. 1 With the SHIFT indicator lit, press the SYSTEM/OUTPUT key so that the screen displays something like the following: [OUTPUT] L LC LS 1 7 5 C LFE 3 4 R RC RS 2 8 6 The screen above shows a 7.1 surround pattern. If you have picked another pattern, you will see only those channels which are relevant to your pattern. 2 Use the cursor keys and VALUE control to navigate to the surround channels and assign the outputs to them. NOTE The output router is always active. It cannot be bypassed. 20 TASCAM DS-M7.1
