The Mix Mode drop-down control provides the following four approaches for working with the
channels:
Mix Mode Mixer Behavior
1. Normal Working with mixer channels independently is the default or “Normal’
mix mode.
2. Paired If you want two channels to be paired so that altering the gain of one
will automatically alter the gain of the other, choose Paired from the Mix
Mode drop-down control for one of the channels you want to pair; for
example, channel 9 and 10 will be paired with each other if you select
Paired for one of those channels.
3. Surround Sound 5.1 For surround sound 5.1, which uses 6 channels, specify for each channel
one of these 6 selections from the Mix Mode drop-down control.
For example:
Input Ch 1 = Multi Left
Input Ch 2 = Multi Right
Input Ch 3 = Multi Center
Input Ch 4 = Multi L Surr
Input Ch 5 = Multi R Surr
Input Ch 6 = Multi Bass
4. Surround Sound 7.1 For surround sound 7.1, which uses 8 channels, specify for each channel
one of the above 6 selections plus two additional Mix Mode selections.
For example:
Input Ch 7 = Multi L Rear
Input Ch 8 = Multi R Rear
Once you have established a pairing or surround sound grouping, changing the gain on one channel
affects all of the associated channels. Also, AGC processing (if enabled) will take into account any
channel pairs or surroud sound groupings.
Any 8 channels may take the input from the Dolby E decoder, leaving 8 remaining input channels to
assign.
Out Bus Assignments
The mixer has 16 input channels and 16 output busses. Initially, each channel is assigned a separate
output bus. For example, by default, mixer input channel 1 is assigned to mixer output bus 1, indicated
by the green button in the Input Ch 1 control. However, you can assign multiple input channels to go
to the same output bus. Or you can have each input channel going to multiple output busses (from 0
to 16).
Each mixer channel has a level control on its input. There is not a separate output gain level control.
