User manual TASCAM DS-M71

[. . . ] D00671100A Professional Digital Surround Monitor Controller OWNER'S MANUAL Ü ÿ Y This appliance has a serial number located on the rear panel. Please record the model number and serial number and retain them for your records. Model number Serial number CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] 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 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). If you are in any doubt, consult a qualified electrician. NOTE 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. B MUTE/DIMMER This 3. 5 mm stereo mini jack socket is used to connect switches which can be used for remote MUTE ALL/DIM operation. 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 connection, together with all other connections, have been made, you should set up the DSM7. 1 to recognize the appropriate the console source (TDIF or slot), as described here. 1 Press the SYSTEM key and press the cursor keys until the cursor highlights the ConsSel parameter: [SYSTEM] MasterSel ConsSel TrkRecSel TDIF TDIF TDIF > Inputs from the console Typically, the console's busses are connected to the DS-M7. 1 inputs. [. . . ] The first is the LCRS (LS, RS) configuration, This allows a control room set up for 5. 1 or 6. 1 to use an LCRS configuraiton without repatching the speakers. This is possible, since the Ls and Rs speakers are assigned the same signal, thereby creating a "phantom" Cs speaker. The second is the LCRS (CS) configuration, where the LS(S) signal is assigned to the CS speaker of a 6. 1 configuration. Both configurations use the same downmix settings, as shown here.
