I have a RX-V675 connected to a SVS cylinder sub via the sub1 preout. YPAO was run with gain at 0 and sub volume at 50% as suggested in the manual. The results of YPAO were -
- all distances were accurate
- all my speakers were set to small, which is correct.
- the LCR and surround speakers were set to either 0dB or a small value like +/- 2dB, sub was set to -4.5dB. I tried increasing the sub gain to no effect
- I set bass crossover to 80Hz
From the setup page, test tones to all speakers are fine, but the sub is not audible. If I turn the sub to nearly 100% then I can hear a faint output but that's obviously not right. With my previous Pioneer receiver, I barely had to set the SVS to 1/4th volume to get enough bass for my apartment. With Yamaha, even without YPAO I should be able to hear bass, right?
Forgot to add - the Sub is set to Normal, and Phase is Neutral. I have heard the test tone but it is really faint and only when I turn the sub all the way up. And YPAO did detect that a sub was present.
But your sub is working, right?
Yes, the sub is working. Look it, I'm no pro at these things so I'd like to think that YPAO got it right or at least in the ballpark! My only suggestion to you is to let your ears be the judge. Pick a familiar movie and listen to the bass. If it's too weak, kick up the sub volume in the manual set-up, not the sub itself. Too strong...turn it down a notch or two. Good luck!
The cable should say 75 ohm. Ypao does output a subwoofer test signal.
I used the same connection in an identical receiver upstairs and the sub plays fine. This was an RCA cable from subwoofer out to sub. That connection didn't play on one 765, but did play on another. By the way, the 'troubled' receiver ran a good test tone to the sub. I just don't get it.
Any help would be appreciated.
