This is excellent.

The pass through goes to the CD input of another Yamaha receiver that he had. It powers four speakers in the kitchen/ dining area next to his main room with the 5.1 system.
Well, 4.1 perhaps? Or, if no sub, just a 4.0?
I included an all zone mute so he can quickly kill the music everywhere to answer the door or whatever.
The people who don't have this soon learn that they want it. It's easier to build in than to retrofit, so kudos!
No noise or ground loops thankfully.
For reference you should check to see if there's infinite resistance between all conductors on the input of the baluns and all conductors on the output. That means the balun is a ground isolator, which is the most straightforward way to have no noise from ground loops.
His processor for his DJ/computer music set up has a line level audio out so that we ran into the receiver. It works fine. He has been warned that at some point someone could quite possibly damage his system with this set up connected to it. I advised him to do some research on the best practice for using a compressor or something. But that it’s a work around and that he is inviting disaster.
This will always be subject to instant ruination by someone who turns things up too loudly, so a compressor would be a good idea. But then you have to be sure that the guy who would turn things up too far cannot get to the compression control.
A good unit would be the Behringer Q802USB Xenyx 8-Input 2-Bus Mixer with USB/Audio. It's got two channels of compression. Most available compressors are rack mount units, which could be a problem. This, though, is a small version of a PA board, so it's also not built to fit into an A/V system. But it would work for him!
If you decide to add that unit, be careful to get that exact model. Behringer uses the same panel layout for at least one other product, which doesn't have the compression.
