Hi;
Its been some time since I made the pyro boxs with the help of the great guys on this forum.
I was woundering If anyone has seen any problums with switching amps putting out higher than audible noise that may interfear with other equpment. Like RS232 or RS485 Serial communication.

Higher in power or higher in frequency? I assume you mean the latter. A switching amp should have a filter to stop RF getting out (harmonics of the switching frequency). On the other hand, RS232 comms should use decent cable and receivers to stop RF getting in.higher than audible noise

You can't just generalize it by topology like that.
Of course it's capable of causing interference, but whether it does or not comes down to circuit design, pcb layout, and final implementation.
