Treble and bass function

RC-607M
Part # 24140607

check whether any loose connection in the board of the unit.

The tone controls are only on the remote, Part number RC-174S. I can create a PDF of the manual if you still need it, just post here.

might have spare onkyo parts

I ran into the same issue and was stumped at first. Then I noticed somehow I had changed the sound processing to "Direct" which meant the signal coming from the source was bypassing all of the control in the receiver. All I had to do is select another option (press stereo for example on the remote) and kick it out of the direct mode.

Turned out to be a level problem.

I suspect that the speaker levels need to be set. You connected everything right - many people would not have connected the sats via the bass section (which has their high pass crossover and overload protection). But I am betting the HSU is turned up a bit on the high side.

Try this. Set all speakers to small, set all levels to 0. Play the receiver in stereo all mode. If the bass is strong, you need to turn the HSU down closer to a natural sound. Then use the speaker setup tone and adjust as needed.

poop!!!
