How happy are you with the mixer? I’m worried about the mono part of it considering my intercom is a stereo one. Also, have you installed an external switch to, for example, mute a nav radio?

Thanks!
 
It works great for me. It's low cost, but you give up stereo through the mixer. If you have an extra audio input directly into your intercom, you could input stereo this way. I have not installed an external switch, but you could.
