Turn off unused channels?

Not knowing the Yamaha in particular it is usually not possible to turn off unused channels / power amps completely within an AVR / amp because of technical reasons.
They will stay powered on.

even if you could (which you can't), it wouldn't accomplish anything... there is no load on the unused amplifiers, so they are only using a TINY amount of power to idle... and i'm not sure what you think you would accomplish by disabling the sub out....

Not sure what you mean, but you can turn off the individual channels and subwoofer output in the AVR's menu.

The individual channel power amplifiers of the unused channels will still have power applied to them with no input signal, but that will use up almost no power when there is no signal being input into the channel.

How do you connect the subwoofer to your system?

Your question only makes sense if you don't have the user's manual. If the manual somehow mystified you, you would have logically refereed to it in your question.

You can download the Yamaha owner's manual here:

The answer to your question has a number of possibilities, which are covered starting on page 111.

You might also run YPAO so that it can help you with this question (page 41).

Good point.

I think the key to the proper answer to this question related to his presumably emotionally-based belief that the receiver is "under powered".

Wanna bet money that an audiophile friend with a more expensive system or a dealer is behind all this? ;-)

yup arny, you caught my inference to his "underpowered" line... i would wager that 99.99% of all posters who "feel" they are underpowered are likely already well "overpowered" for their actual usage...

that would be a safe bet... might as well add in "reading audiophile magazines/blogs/postings without engaging the editorial bs subroutine in the brain", and complete the troika of the usual suspects...
