The simple answer if any mix
console audio is actually flowing through a
Crestron device -- no, the
system is not connected properly.
Correct physical signal flow is
Console >
DSP (
Crestron Controlled) > Amps > Speakers.
If the signal flow is actually
Console >
Crestron Audio In/Out >
DSP > Amps > Speakers, something's kooky. It's not unusable in this configuration, but it's bad form to insert
Crestron audio processing into the signal flow when you have the BSS for that. Also,
Crestron audio processing blows chow.
What
@FMEng pointed is out is on the right
track though. This sounds like a
gain structure issue. Somewhere along the
line a
gain is turned way up/down at one signal flow
stage and way the opposite in the next
stage. By any chance was the
console not originally intended to
plug into this
stage jack when the
Crestron/BSS was installed?
Most systems don't actually use stereo. It's good form to take L/R inputs from the
console and do an L/R sum within the
DSP whether the
speaker system is actually designed for stereo or not because some day it might be, but if the
system isn't designed for stereo coverage there's no
point for someone trying to cook up a stereo mix except for sound effects (i.e. a train passing left to right -- even if you aren't in the direct coverage of the Left speakers, you can get a spatial sense from the indirect coverage that a train is gradually passing Left to Right).
For installed venues,
console directly into amps/speakers is both dangerous and user-hostile. With exception to pro venues that will occasionally bypass the
house EQ for a
road guy to do his own thing, the
DSP serves a critical purpose of providing a flattened, peak-limited, balanced, delay aligned, cross-overed, resonant-frequency-notched tuning. Even in pro venues, this is how the
house DSP's are set up by default and somewhere a password can be entered for the
house engineer to allow the
road guy to bypass the
house EQ without giving the
road guy enough rope to blow out all the drivers with.
