Is There A Single or Multiple Fixed Output Levels for Sonos Connect (S1)?

I had been using the line-out RCA jacks of my S1 Sonos Connect (using fixed output setting) to drive into Tape 1 input jacks of a Luxman receiver, and all worked well. After a long hiatus (since last Christmas), I tried to send Christmas music from Sonos to the Luxman, and can barely hear the music - its coming across at a very low level, so much that turning the receiver volume up to 9 I can hear that the source is playing but I can’t hear it to listen to it.

I’m wondering if there is someplace where I’ve accidentally specified “low level” when I need to get medium or high level signal out of the Sonos Connect? BTW, to test, I switched from the Tape 1 input on the receiver to the Tuner and the volume level was MUCH HIGHER.

Anyone have any ideas on what I should do to get a higher level signal over to the receiver?

Thanks, and Happy Holidays!

Hi ​@bclarkeva, welcome to the Sonos Community!

I’m sorry to hear that the music is very quiet when playing to your Connect.

I don’t think it would be something you’ve accidentally pressed but I’m not sure why it would have changed if it was fine before. If you go into your system, you can adjust the Line-In settings, specifically Source Level is what you’d want to adjust if the audio is quiet. You can do this by following these steps on the Sonos app:

Sonos App:

  1. Go to the Settings menu and select the appropriate Room.
  2. Various Line-in settings can be found under Line-In.

Sonos S1 Controller

  1. From the Settings tab, select System.
  2. Under Products, choose your product that has a Line-in connection.
  3. Adjust your settings under the Line-in section.

Our support article for adjusting Line-In settings also has these steps and explains what each setting does.

I hope this information helps!
