This has been bugging me for a while. The line in inputs on my (new) Amp is coloured red and white. There’s no indication of L and R but to my knowledge in all audio equipment Right is red and Left is white. Most,if not all, are marked that way.

When i connect a CDP for example using Line in inputs (red to red and white to white) and play a audio test CD what should be coming out of the left speaker comes out the right. I have learned just to live with this by crossing the connections to my CDP. Has anyone else experienced this ?

What speakers do you have connected to the Amp? Are they wired to the Amp correctly?


Here is an image from the user-manual showing the L/R speaker connections, looking at the Amp from the rear connector panel, if that assists?


Found the problem ! Along side my Sonos Amp I also run a old school tube system to Altec speakers. i use a speaker/volume control switch to join both and that’s where the problem was. I made some modifications a while back and i crossed the connections from the Amp to the switch. Rookie mistake! (Even though I had traced all the wires and connections I still missed it) All is good now. Thanks
