RX-V757 Not Recognizing All Speakers...?

[SilverJS]

Hi all,

Just completed my DIY full HT system, and I've run into a bit of a problem with my 757...

Setup :

757 -> front preouts to Behringer mixer (for my keyboards) -> Behringer Ultracurve DEQ2496 - > Behringer CX-3400 active crossover -> Yamaha PC4800N for mains, behringer EP2500 for subs. I prefer having more control over subs this way, because I enjoy crossing them over higher (I have two, at the front).

So - I had setup everything and adjusted my levels. I got a bit suspicious, as I needed to raise the center and satellite levels to the max, and the mains to almost nothing. (This doesn't surprise me for the center, as it's a 4-ohm and I know the 757 is not rated to power it - I plan on getting a separate amp for it - but for the satellites...?)

The problem was, only the L and R lights were lit up in the receiver's display. It didn't seem to recognize the center or satellites. I don't expect it to recognize the sub (I have it setup to send LFE info to the fronts), but it should see satellites, at least...?

I then thought it might need the auto setup, and I ran it, and it gave me roughly the same results (huge level imbalance, L and R only). When I play a movie, there is some sound coming out of the center and satellites, but I can't help but to feel something's amiss, esp. with the satellites...

BTW, said lights in the display do light up in the auto test.

Any bright ideas? If it matters, I use an LG DVD player connected via Toslink.

Thanks!

Just go into the menu and make certain that you "say" yes to what ever speakers you are running and then calibrate them all level with a SPL.

One more thought. Does that EQ have gain control on it? Perhaps it is set too high, the ext amp has a different gain than the 757. All could be affecting that huge imbalance on the trims.

Try checking your DVD players menu as well. Sometimes even though optical is turned on, 5.1 is not.

Not sure if this helps, but I think the channel indicator lights in the front panel display only show what channels the receiver is getting, rather then what channels it’s using.
