Distorted sound-Sonos Port

  • June 2, 2022

I'm using my Sonos Port basically as a pre-amp, powered by an Acurus A150 2 channel amplifier, and an Adcom GCD-750 CD player.  I'm getting really distorted sound.

I've tried taking the Source Level down to 1. I've played around with the EQ. Nothing is working. When I remove the Port and connect it to my volume controller, it sounds perfect.

Any suggestions?

I'm running analog cables out of the Port, into the amplifier.

I think the Port should only be connected to the CD player, not to the amplifier. Connect from the Port’s Digital Out to the CD player’s digital input using a digital audio coaxial cable.

If I don't connect the Port to the Amplifier, how will sound get to my in wall speakers?  Also, I tried the digital out to digital in and then the Line Out option disappeared from the Music/Browse options.

Ok, I see what you are doing now…

Connect from the Port’s analog audio OUT to the left and right inputs on the amplifier. Then connect the CD player from the left and right audio outputs to the Port’s analog audio IN. If you are still getting distortion, try different audio cables. Also try the different Line Out Levels settings for the Port in the Sonos app.

    Is your Port set to Fixed or Variable output? The A150 has quite a low input voltage spec and the Port could potentially overload it. 

    Are you able to test the Port into any other device to verify its outputs are working correctly?

      Why? Do you think they can offer better advice for this specific problem?

      First time here. Saw it on a few threads done the way. Didn't mean to offend.

      Thank you for this perspective. I have it on Variable. There's no volume control on the Acurus so I'm not sure how Fixed would work. Would limit the volume to something low versus 100/full?

      Now that you mention it, I do have an Onkyo AV receiver that powers 4 in ceiling speakers that I could test it on.
