EQ not working with Sonos Home Theatre or Pro-Ject Debut Carbon EVO Turntable

.: Greetings, all. Last year in 2024 I purchased a Pro-Ject Debut Carbon EVO turntable. With help from many on this forum, I was able to buy a Sonos Port pre-amp, and all was well with the new product. I could easily switch between the LG tv and the Pro-Ject turntable.

A couple of days ago, I decided I wanted to change some of the EQ settings for the sound for the turntable. I discovered that changing the Bass, Treble, and Balance Control Settings does not make any difference, nor does the Loudness option.

I have no idea how to correct this function. The rest of my Sonos speakers (Arc SL, two One SL’s) are working fine. 

If anyone has any advise on how to correct the currently non-functional EQ controls on my Sonos App, please let me know. Thank you in advance for your assistant and guidance.

If you are listening to the turntable through the ARC, adjust the ARC’s tone controls.

May I ask why you didn't go with the Victoria Carbon instead??

Are you changing the tone controls on the Port or the speakers you want to listen to? 
If it’s the Port than those EQ changes effect the output RCA’s of the Port. I made this mistake early on.

Of course. It was recommended to me by the manager of my city’s high end audio business. I wanted a simple, uncomplicated turntable, and the Debut Carbon fit the bill. I’m not an audiophile, I just wanted to listen to some of my albums that have been gathering dust for too long.

Hello, tnprime. I’m not sure I know what you mean. I am using the Sonos App, which is up-to-date. Then I go to Settings (in the upper-right corner), I click on “Pro-Ject Turntable.” and then click on EQ. On the screen below, no matter where I slide the settings for Bass, Treble, or Balance, nothing changes. Setting to “Loudness” also makes no difference.

I don’t think I’m doing anything with the Sonos Port. When I expand “Port” in the app, it shows me the Network Status and Serial Number only.

Please advise, thank you.

Maybe see if setting the line-out level in the Sonos App to ‘fixed’ just temporarily …and then switching it back to ‘variable’ will go onto resolve the EQ issue for you🤔?

See attached screenshot, just as an example.

.: Hello, Ken, and thank you for your suggestion. I was unable to locate the “Line-Out Level” screen on my Sonos app. My Pro-Ject turntable is connected to the Inputs on the Pro-Ject Phono Box MM Pre-Amp. The Output cables go to the Inputs on the Sonos Port. From there, the Sonos Port connects to the Arc and One SL speakers via Bluetooth. So I’m not sure what to do from this point forward. If you can, please advise further. Thank you kindly.

In the Sonos App goto ‘Settings’ (gear icon top right of screen) and scroll the page until you see the Sonos Port room - select that and scroll page to the ‘Line Out’ category and select the ‘Line Out Level’ to access the settings and page shown in the screenshot I posted earlier - then try changing the settings mentioned.

The line-out EQ settings will become available in the ‘Settings/Port’ ‘room’ area too when the line-out level is set to ‘variable’. See attached.

Hello, buzz. Thank you for responding. Can you tell me how to to do that? I can’t find any reference to “tone control” for the Arc Unit in the online manual. Thank you.
