9.10.4 5.1 Downmix
Open the "System -> Definition -> Parameter = Surround Downmix (dB)" branch of the 'Tree Definition' to define
the downmix which is used when a surround source is routed to a stereo summing bus.
You may set up 5 sets of downmix parameters so that the operator may change the downmix according to
their requirements. Once selected, the downmix parameters are applied globally to all surround to stereo
assignments.
If a surround source is assigned to a mono bus, then the stereo downmix is converted to mono by subtracting
3dB from, and then summing, the L and R channels.
