Port Line-Out very low volume.

I have a Port connected to an Audiolab 6000A amp in a rack in my garage, connected to speakers in the house.

The amp always starts at a default volume level of 0db. At this level, the Port’s output is very low and I either have run the Sonos App at near full volume or go out to the garage and turn the amp up manually every-time it’s turned on. I’ve set up the 12v trigger so I can turn it on via Sonos in the house and don’t think I should have to trudge out to the garage to manually turn the volume up every time…

Am I missing a trick?

What’s the difference between Variable and Pass-Though output on the Port? I thought Pass Through was more for AV set ups (mine is just for music) but would this work better? Would the Amp be compatible?

Sue Denim,

Have you perhaps tried setting the Port’s line-in Source Level to 8, 9 or level 10 in the App “Settings/System/[Port Room Name]” and set the Line-Out to ‘Fixed’ which is equivalent to full volume and then controlling the volume using the audiolab Amp?

If you prefer to control the volume with the Sonos App, then set a desired volume level on your amp and change the Line-Out on the Port to ‘Variable’.

This is the section from the documentation relating to Fixed / Vriable / Pass through https://www.sonos.com/support/en-us/sonos-user-guide/index.html#t=sonos-user-guide%2Fport%2Fport.htm%23TOC_Line_outbc-6&rhtocid=_0_2_9_5

Pass through will only work if the amplifier supports it - but this would be the answer if it does.

Once everything is on does the port provide a suffiient level to drive your amp to the volume level that you would expect by adjusting the the amps volume control? If so your real problem is the amp starting up with a default level. Sonos cannot do anything to change this.

There is nothing specifically wrong with running the port at high volume if this solves the problem

My question relates to a Sonos Port. It is connected to my receiver using the analog outputs into anolog inputs on a receiver. When i use a different source to stream music such as cable box, XM, or other source the normal listening level is -20. When I stream music thru the port I need to increase the volume on the receiver to +10 and crank up the volume on the Sonos app to be at a similar level. I’ve looked around the app but cant find any adjustments. I suspect there is a hardware setting that can be modified. Just wondering if its something a consumer can get access to.

I have the same issue - I watch my TV connected through my Sony amp. When I switch over to the input for my Sonos port (I have a digital cable connected to my amp) the volume is super low. I can then crank my Sonos port volume all the way up, but it really should be putting out volume at a lower setting.

it’s like the TV output volume to the amp is normal, and the Sonos is super low.

Frankly I’m also confused by the difference between “Variable” and “Pass-through” volume control on the Port. Seems like they can do the same thing.

Hi @marcsanrafael.

Welcome to the Sonos community and thanks for reaching out to us.

Choosing variable from “Settings/System/[Port Room Name]” and set the Line-Out” allows you to control the volume of the Sonos Port output through the Sonos app.

Choosing Pass-through would not allow you to change the volume of the Sonos Port on the Sonos app as it only projects the Volume coming from the receiver.

Here is a link to better understand variable and pass-through option on the Sonos app.

I hope this helps.

Hi @mvmauro.

Welcome to the Sonos community and thanks for reaching out to us. we apologize for the long wait.

Choosing variable from “Settings/System/[Port Room Name]” and set the Line-Out” allows you to control the volume of the Sonos Port output through the Sonos app.

Choosing Pass-through would not allow you to change the volume of the Sonos Port on the Sonos app as it only projects the Volume coming from the receiver.

Here is a link to better understand variable and pass-through option on the Sonos app.

variable = dual volume control (both the Sonos app and the receiver.)

Pass-through = single volume control (receiver only). Sonos app is able to adjust the Volume on the Sonos Port.

I hope this helps.

Thank you Paul - however the original question is that Port seems to use a lower base level volume than other audio. That is the original question.
