1 – About the unit The TASCAM DS-M7.1 is designed to help you manage the monitoring of mixes of surround sound projects. CAM 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. All major surround formats are supported, from LCRS to 7.1.
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.

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). 9 REMOTE IN 1 Use this as an alternative to the front panel REMOTE IN 2 connector when using the front panel as a remote control. See “Making up a remote control cable” on page 38 for details. A RS-232C Reserved for future software upgrades.
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 When making connections between the DS-M7.
3 – Connections the console outputs, and may not be monitored directly from the DS-M7.1. 1 Outputs to the tracking recorder These connect to the recorder inputs. These may be monitored as BUS signals from the DS-M7.1. When this connection, together with all other connections, have been made, you should set up the DSM7.1 to recognize the appropriate tracking recorder source (TDIF or slot), as described here.
3 – Connections Console and MasterRec (mastering recorder). The second and third lines of the screen will be automatically filled in depending on both the source and the settings made elsewhere in the system as described in “Routing and patching” on page 19. Possible values are: Source Possible sources High-speed connections cannot be made using the TASCAM DM-24 digital mixing console.
3 – Connections Error Meaning number Appropriate action to take 7 Frequency error The master clock is not a recognized frequency (e.g. 32 kHz). Check the master settings and correct, if necessary. 8 AES/EBU preamble error (normal) At normal sampling frequencies, the preamble of the AES/EBU signal acting as the clock source cannot be read by the DS-M7.1. Check and correct settings on the clock master. 9 AES/EBU preamble error (high-speed) At high sampling frequencies (88.
3 – Connections 1 Press the SYSTEM key, and use the cursor keys until a screen similar to the following appears: [SYSTEM] MonOut 2 < Use the VALUE control to select between POST (the digital signals mirror the analog signals) and PRE (the parameters described above are ignored). POST 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.
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. than the open/closed status of the switch triggers the change in the unit’s status. 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.
4 – Routing and patching When the physical external connections have been made, it is time to set up the internal connections within the DS-M7.1 as described here. 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.
4 – Routing and patching 1 With the SHIFT indicator lit, press the STATUS/INPUT key so that the screen displays the following: [INPUT SUM ROUTER] Format LCRS(LS,RS) Input Output 12345678 1 *------- 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.
5 – Using the DS-M7.1 Once you have set up the connections, assigned the inputs and outputs, and followed the procedures in the Setup Guide, you can start using your DS-M7.1. Dimming the output Press the DIM key to dim the output by the amount set in “SPL Reference Level” on page 17. The DIM key lights when active.
5 – Using the DS-M7.1 The parameter to the left on the second line allows you to choose between the two types: TYPE1 and TYPE2. 80/100/120 Hz 48dB/oct Type 1 L HPF L C HPF C R HPF R LS HPF LS HPF RS RS -15 / 0 dB (-15dB default) LFE SW LPF -5/ +10 dB (-5dB default) LC LC RC RC Type 2 80/100/120 Hz 48dB/oct -12.0 dB L L -1.5 dB C C HPF -12.0 dB R R -1.5 dB LS RS HPF LS HPF RS -15 dB SUB LFE LPF -5 dB SW LPF (default OFF) LC LC RC RC 22 TASCAM DS-M7.

This is set together with the MCH>LFE parameter described above.
6 – Note on DS-M7.1 usage Many pre-mixes for film are made that are greater than 8 tracks. The DS-M7.1 can still be useful in these conditions, as explained here. If a large format (24 or more output busses) console is used, a number (8 or 16) of the busses can be used to feed the stem recorder. Stem recorder tracks return via faders The returns from the stem recorder can then be fed back through the console inputs and routed to a different set of eight busses, which are then used to feed the DS-M7.
7 – Downmixing Downmixing, as explained earlier, is the process of folding a surround mix into a format using fewer channels. This is done for the purpose of checking compatibility. Downmixing is enabled and disabled on the DSM7.1 using the DOWN MIX/MONO key under the SPL readout and control. When downmixing is active, the key is lit (it flashes in mono downmix mode, see below). Available downmix targets Source pattern 6.1 5.1 LR MONO 5.1 LCRS 4.
