It is really nice to have the FBA on the Outputs, but it would be AMAZING to have them on the inputs. Like… the RTA would find the offending frequency and cut it on the source, so we could use the GEQ on the Outputs, or just another instance of FBA there, as well. It would be a huge upgrade to this great mixer line.
The reason they are on the output is so that the system doesn’t “chop up” the input’s sound unnecessarily. The input might be going to several different destinations and most outputs wouldn’t need an FBA.
Even if you wanted an FBA on several outputs, they would all need different setting (ie each output would likely need to cut different frequencies with different gain reduction) to avoid feedback, so putting the FBA on the input would actually cause more problems than it solved.
I assume that’s not the reason.
Because one could also argue this way: In the case of a single microphone is causing feedback in the PA system, why its entire the most important PA frequency response needs to be corrected, instead just that of the problematic microphone?
I would rather assume that the main reason for the outputs is that a more comprehensive EQ section already exists there.
The 20 filters of the GEQs are already located there, which can alternatively be used as 4 PEQs + 16 FBAs.
So you only need all of this 8 times for the CQ outputs, instead of up to 16 times additional (!) for the inputs, which would require significantly more processing power.
Those are all fair points!
This would certainly make my life a lot easier.
