Just realized that there are no Balance Control on the Stereo Bus Masters. I think they should be added because that is a basic Function.
I know some People think there is no need for that, but there are definitely situations where it is at least helpful.
For example, think of a very low budget Setup - let’s say on a school campus - with a “Frontline” consisting of two “big” active 15"/2" Speakers hanging at the Front traverse. No Controllers or Speaker Management System, no Amp, no way to reach the speaker Controls during the Show.
Room is often a Problem on such place, so it may easily happen that the Audience is seated in an angle and somewhere slightly off-Axis from Stage (may also happen if there is additional space needed in front of the Audience but not on Stage, for example to place a Jury, a Speaker, some Gifts or whatever else).
Although Conditions are not ideal, the “Audio Man” will wnt to deliver good Stereo Sound anyway. A Balance Pot on Main Bus would help him to do this without having to adjust up to 48 Balance Pots of several Inputs or waste a Matrix Bus for that.
Another Usage could be multiple Audio Zones some of which do not allow a symmetric speaker placement - that can happen easily on Sports Events. As well, it would be better to have a Master Balance Knob here instead of having to adjust 48 Channel Balance Sends (and maybe each of them for 13 Stereo Busses)!
The Balance/Pan rotary Control is already there. So why not simply give it a function when selecting a Stereo Bus Master?
