Hello

During the process of installing an Intercom, there come together many signals. sometimes there is a mono signal that needs to into a stereo input or vise versa.

How do I handle this? Do I only connect the R when I come from Stereo to Mono?

Thanks for any input!

Regards, Dominik
 
Stereo to mono: both input signals wired to the single mono input. Otherwise you will only hear one channel.

Mono to stereo: wire the signal input to both stereo input. That way the signal gets passed to both sides. If you don't, you only hear the signal in one channel but wiring to both also has the benefit of if you lose a stereo channel you still get the mono signal through the other channel.

You better isolate these channels with a some resistors or you risk damaging the output amps.
