I am inquiring how robust A&H input circuits are. Other mixers are able to sustain this. A Behringer X32 is for FOH/Monitors. GLD80 will be for TV broadcast audio. I have a need to parallel these mixers by making a number of XLR Y cords. Will my input circuits be harmed if I connect into a X32 preamp presently providing +48 volts phantom power?
Please note I am not asking if it is proper or advised. I am not going to spend the coin on transformers for the two events that need this done. Nor do I plan on renting microphone splitters. I am aware of ground loops too.
I would not take that risk.
People used to and have ground lifters (back in the old days ).
If you were close you could borrow one of my 40 channel splitters.
You said “I’ll make some”?
How many channels?
Surely they cant be that expensive to hire?
I definately wouldnt make any with transformers now we are in the digital era.
There is no harm in applying external PP +48V to the preamps on GLD, AR2412, AR84 or AB168. Most mixers are built with protection on input circuits to facilitate analogue Y split for FoH/Mon applications etc.
I would just make sure the channel is muted when you are patching things up.
