Input Parameters for 5.1 (surround) Channels

If a channel contains the input balance function, a balance control will be
available in the pan page. This balance control is actually set before the mono
switch in the signal path, within the input section of the channel. Hence it is
possible to use the input balance function to correct the levels of two channels
feeding a stereo input channel, and then add them together to become a mono
sum. A practical example is the feed of a stereo channel from a VTR, one
channel containing ambient signals and the other one being the commenta-
tor. In this case the 2-channel mode is set to 'mono', and the input balance
function is used to correct the mix between ambient and speech signals.
Compared with mono or stereo channels, the global input control section of a
surround input channel is slightly different: There is no phase control switch,
and the 2 Ch Mode selector has been replaced by 5.1 oRdeR.
As it is the case with mono or stereo channels, the digital gain stage acts as
a trim after the A/D converter. Input gain can be set in 1 dB steps in a range
of ±24 dB. The default value is 0 dB. In a 5.1 channel, all six surround input
legs are treated simultaneously.
Like the 2 Ch Mode function in a stereo channel, this functionality provides
a kind of patching within the 5.1 channel. The bus order in Vista consoles with
SW V4.0 has been changed according to the ITU standard (L, R, C, LFE, Ls,
Rs). The 5.1 oRdeR selector allows converting different surround formats
to the ITU order.
