Phono level is different than line level. Thu both use RCA jacks. Phonographs have no amplification so there is a bias signal coming out of any phono level input. Line level (everything except for an actual phonograph) inputs are expecting an already amplified signal.

Ah, my mistake!  God, I know I'm gonna make that mistake again.  I've been making it for many years!

"Phono" is still used interchangeably with "RCA" by many engineers to identify cables and adapters (XLR, instrument, TRS, etc).  If you start talking about jacks/inputs or anything other than line level signals, it's best to avoid the word "phono" unless you're talking about an actual turntable input.

Ah, the memories. I used to daisy chain two of those Retocon switchboxes together back in the day. It was a very good unit, available pretty cheap as I recall. I used to use one of those Madcatz ones too, it wasn't quite as good as the Retocon IIRC, but still fine for composite.

These days, I use a combination of my Onkyo receiver (it has 3 component inputs) with one of these switchboxes:





The reciever's signals are perfect, I just wish it had more ports. The Pelican works better than just about any switchbox I've seen, but there is still a slight bit of interference if you are looking very closely.
