Need Help with my Receiver

This reciver has 110w per chan.
I would recomed you recheck your speaker hook up.
Try un-hooking one speaker at a time. Look for shorted wires.
The sub woffer has built in power amp, so an audio cable from the reciver the sub is used, it sould have a volume control on it. John

There is no problem with your receiver. Although it is rated at 110 watts x 7, that is actually @ 6 ohms, @ 1KHz, with 0.8 THD, one channel driven. With all channels driven from 20-20,000 Hz at 8 ohms with less than .1% THD which is more a normal rating it probably puts out about 40-50 watts per channel and about 70-80 watts with one channel. That is more than plenty to drive those JBL and most speakers very loudly (don't worry here, many receivers in the under $500 class tend to exagerate the power ratings a little, 50 watts per channel is plenty for most speakers).

The JBL speakers you have should be able to handle the power OK. If they are being driven too loudly then you will hear it in the form of audible distortion from the speakers. The powered sub makes driving the 7 speakers an easy job.

Troubleshooting: Try unhooking the 6th and 7th speakers. Same problem?

I would think that #2 is probably the most likely problem. I repeat the advice to check carefully all your speakers connection and make sure none of the wires are touching. Check all speaker wire for cracks or breaks.

It is either shutting down because the amp is overloaded becasue of low impedence, usually not a problem in that class of speaker....or there is a short somewhere that is shutting it down. Many more expensive speakers will shut themselves down they are overdriven. Make sure the speakers are hooked up to the correct speakers connections (all "A" speakers) and that the sub is hooked up to the sub RCA output jack labeled "sub" under pre-outs or subwoofer out.

I bought the same unit yesterday and had the same problem. I would double check all of the speaker connections to ensure there is no contact with the chassis or between speaker wires. ALSO, check the integrity of the wires. That turned out to be the problem with my unit. Now it's fine. Hope this helps!
