Before you start using the TASCAM DS-M7.1 to help you with the monitoring of your surround mix, there are a

few operations to be carried out which will help you use the unit most effectively.

These are: trimming each channel so that each channel is correctly balanced relative to the others for your listen-

ing position, adjusting the delay for the channels to avoid phase delays, etc., and setting up the overall SPL (loud-

ness) of the unit.

First, you should set up the DS-M7.1 so that your system is something like the one pictured here. For full details,

see the Reference Manual, paying particular attention to the notes regarding word sync. Also note that this illus-

tration shows a 5.1 system with no insert loop attached to the DS-M7.1. Your setup may differ from this, but the

principles will be the same (the connections between the monitoring amp system and the monitor speakers are

omitted for reasons of clarity.

Note that the connections between the master recorder and the tracking recorder are bidirectional, as are the con-

nections between the console and the DS-M7.1.

For full details, see the Reference Manual, paying particular attention to the notes regarding word sync. Also note that this illus- tration shows a 5.1 system with no insert loop attached to the DS-M7.1.
Page 2 The DS-M7.1 provides you with a pink noise generator to allow you to set up and calibrate your monitoring sys- tem for optimal results. You will also need an SPL (sound pressure level) meter. Absolute accuracy in this case is not of prime importance—relative levels are what are being set up here.
Page 3 Set the SPL REFERENCE LEVEL control so that the display shows the reference level you want to use. Play a nominal level signal (pink noise) through your mixing console into the DS-M7.1. Take the reading of the SPL meter, and adjust your amplification system until the SPL meter shows the desired level. You may now use the SPL REFERENCE LEVEL control to reduce the monitoring level, but only increase it if the material permits.
Page 4 The DS-M7.1 contains delay circuits to allow the monitoring to be adjusted. For this process you will need some kind of tape measure or ruler to measure the distance between the listening position and the speakers.
