My Echo (2nd Gen) is paired with a Bluetooth receiver which, in turn, feeds that signal to a 70 volt Mono amp that services the entire house, one speaker per room. Listening to the music, it sounds very much like I am getting only the Left or Right channel of a stereo signal rather both channels in a mono signal.

I see no control in the App to configure this sound output. I assume Mono is the default setting. Is it possible that I am getting one channel or the other? If so, how do I correct this?

  • Looks like your Bluetooth receiver cannot give both channels to your AMP. This can happen due to audio jack type. Because you need to have a Stereo to Mono convert for this to resolve. Bluetooth receiver giving both channels to Mono AMP, but amp can only take one part fro stereo jack. – LahiruTM Sep 28 '18 at 4:50
  • Lahiru, I'm running a "stereo to mono" cable from the Bluetooth to the amp, but given your analysis, I will replace it with a new one and see if that resolves the issue. – DJGray Sep 29 '18 at 16:40
  • Confirmed. Bad cable. Thanks Lahiru for knocking on my head a bit. I should have figured that out. – DJGray Sep 30 '18 at 16:42
