See EQ Mode on page 59 of the owners manual to set the bass and treble for the front speakers, presumably for 2 channel mode. For multi-channel mode there are several pre-programmed audio modes listed starting on page 43 and music mode starting on page 44.

The problem is in the audio output semiconductors, they have shorted causing the fuses to blow and it is in auto protect mode to prevent further damage. I recommend a professional to assess.

If you have checked the speakers and wiring, the right channel has a audio driver or output problem, which explains the low volume, static, and distortion. A service technician will be required to fix the receiver so it will balance the left side.

Yes! it can be repaired, the technician will need to replace the audio output ic and maybe some drivers.

try to check balance adjustment if working.

Repair time ...circuit board to front channel has a fuse prob or capacitor

Sounds like damaged channel in output circuitry. Take to pro/tech

Most likely it's due to bad solder for the Blue Relays.It can be fixed by re-soldering.

Hi, Happened across this forum looking for some remote info. Had a similar problem with my 945...main speaker outputs started to click off & on, no rhyme or reason. Found that the solder joints on the speaker output relays were cold (poor soldering). Actually happend twice, two different relays. Took me a while to find it, reflowed the solder, that solved the problem, over two years ago now. Are you able to dig into the receiver? Do you have a (good) soldering iron and some solder? If not take it to elec. shop and tell them to look for cold joints on the relays.
