Tascam DS-M7.1 owner manual Routing and patching, Choosing the surround format

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 DS- M7.1 provides flexibility in the way in which incom- ing 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 follow- ing way (LR (stereo) is not shown, as it is assumed the reader is familiar with this format!):

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):
