Hi there! <<NOTE: already solved before completing this post! Will post anyway to help other users>>
I'm attempting to set up a Yamaha RX-V673 AV receiver and thus far everything has been great. Speakers sound great, lovely. But I can't seem to get the subwoofer to run.
I can get a test tone out of it on the subwoofer channel, but in practical use I'm fairly sure it's not working. If I bring up the system info the subwoofer channel is greyed out but each of the other five I have connected is highlighted and active.
Does anyone with experience with this AV receiver know what the problem is? I've tried all permutations of surround decode modes and straight/other mixing settings.
I must point out that it might be that it is
working but, being properly tuned through YPAO, the cone simply isn't moving at the volume levels I'm using. It's not like I'm not getting low frequencies out of the other speakers either - quite the opposite in fact. Perhaps I should crank things a bit...
... OK, even as I write this, PROBLEM SOLVED. Stopped to read another thread, apparently YPAO sets all speakers to "large" more often than not. They are
large but this also disables the sub. Soon as I set the fronts to "small" the sub channel opened up. thread in question here
