What's going on with the VMS4 output?
I've just been running in analog mode to check both my mic channels and all four line inputs for distortion, and noticed something.
Having set my channel gain and master output level to read 0dB max, I turned up the EQs.
Now what should happen is that the master output reading on the VU should increase as each EQ band is turned up.
There is +6dB of boost on each band, so with all three up there should be a significant increase showing on the VU.
But there is NO INCREASE WHATSOEVER. Instead all that happens is that the audio becomes compressed and distorted.
Perhaps this is why so many are complaining about distortion. They are boosting EQ and part of the VMS4 internal circuitry is saturating.
So I'm wondering now, exactly what is going on internally?
(later) I've also just noticed that there is a lot of bleed into the main output from the cue signal, when the cues are pressed with a signal playing.
This is audible even when the master output is at zero.
Finally, my channel two input bleeds through to the output even with the fader at zero and no cue pressed.
