Onkyo 876 Speaker Settings

[admin_exported]

I am currently awaiting my rear speakers, but until then I am just trying to run 3.1. I can't seem the get the Onk to pick up the Centre Speaker as hard I have tried. Also the Onkyo is not outputing anything to the Subwoofer either but the the Left and Right Speakers are working fine. All my connections are spot on. I am baffled to why the centre and subwoofer isn't working. Any help, please?

Just noticed the subby doesn't come on sometimes with the Onkyo switched on, yet when I turn the Onkyo off, the subwoofer turns itself on.

When you run the auto set-up, does the test tone come from the centre and the sub? If not, I'd double check the wiring. If the wiring is good, are you certain the centre speaker is good?

I'm not familiar with your sub, but when I left my sub on 'Auto' mode, it would only click into action when it detected a signal. If the scene you're listening to has a lot of chat, it may well not be bassy enough to activate the sub.

Sub turning itself on when you turn the amp off is a strange one, unless it's sending a 'pop' signal when turned off that brings the sub out of 'auto'. (does it turn off again?)

When I ran the auto set-up, the test tone only came from the front left and front right. Checked the wiring again and everything is fine, the centre still isn't registering. The subwoofer is working perfectly fine now, I stupidly had it in the Multichannel option

The centre is really annoying me though, I know everything is correct, wiring and connections but there is nothing at all, when the Onkyo runs the auto set-up it goes from the front left and skips the centre and straight on to the front right. Maybe there is something wrong with centre.

Does it do this when it does the initial channel check before doing the calibration run?

If so, it may be a fault in the receiver. If not - in that there's a pause during the channel check -, it's not finding the centre, which may be down to a fault in the centre speaker or the receiver.

Andrew, it does not do this with the initial channel check. I meant to say, the receiver actually sent a test tone through the centre last night. I thought brilliant, problem sorted. So I ran the auto setup again, unfortunately, second time around, it didn't work, not test tone. The calibration went from the front left and missed out the centre going straight over to the front right. I suspect that centre could very well be the problem, as a friend brought down a B&W centre and there wasn't a problem at all.

Yup, sounds like a speaker problem to me...
