I'm going to upgrade my battery driven soundsystem.
I use sla batteries.
It is the first time i implement dual supply amps (IRS2092).
I attached a sketch that shows a possible scenario:
There are 3 amps and a preamp that use different power supplies.
Amp1 and the preamp are connected to a single 32V supply.
This is basicly the setup i was using all the time (sometimes with more amps on the same supply).
Would it be better/safer to put filters or diodes in front of each amplifiers power inputs?
Amp1 has BTL outputs.
The preamp is working with a 'virtual ground' as bias voltage.
Signal GND was no problem here.
Now Amp2 and amp3 will be connected to an dual 50V supply.
The amp modules have power GND (center tap of the batteries), signal GND and Out- connected together on board.
What is the right way to wire this system?
