The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.
The player processes the audio signal using two different reference frequencies. The "R"... -
I have a Steinberg UR44 audio interface that I had in storage for a few years, and now that I want to use it doesn't power on. I want to take this opportunity to learn electronics repair so I am trying to repair it for learning experience.

Hi all,
If anyone has these files, please upload and share them.
I ruined my laptop with coffee and now I need to fix this guy, but I can't find the schematics anywhere.
I will be really grateful to the person who posts these files.
