GAS Thoebe preamp: Stereo push buttons?

I just picked up this preamp.
It has 2 stereo push buttons marked stereo A and stereo B

The preamp refers to the left and right channel as A and B.

I am at a loss as to what these buttons do. When both are
pressed it sounds like the system is in mono mode.

anyone out there have a manual ?

thanks

It has been several years since I replaced my Thoebe preamp, but I recall that it had the same phenomenon with the mute button when the volume control was set at minimum: signal level at the preamp outputs would be louder with the mute engaged than with it disengaged.
