ASR X-pro schematics

this will be rare to find any info on but I need the schematics to try to fix my ASR-X pro. left channel is 30 dbs lower than right channel, and one of my selection pots is being flaky.

I suspect a cold solder joint to the former and a bad encoder in the later. the encoder is easier to fix but the left channel will be an issue. any info will be helpful

thanks in advance

See if Ensonic will sell you a service manual, or a copy of the schematic
