How do I get maximum, quality, output for my Onkyo nr-tx807

SOURCE: Onkyo TX-SR500 Dolby Digital problem

I just read over the problem you were having with your Onkyo TX-SR500 receiver. It sound like the unit needs to be setup for all five channels.Sence your symptom says the diplay shows Dolby D3/2.1. According to the owners manual with the remote control look for speaker setup whin the button is pressed the current speaker setup will be shown in the display. Press the preset/adjustment<> to change the current setting to five speakers. the listening mode will automatically change according to the number of channels you selected. Hope this helps.

If you have any of its sound outputs connected to a TV or tape deck do they get the signal? If so, then we know there is sound processing somewhere inside the unit but not emerging to anyplace that requires amplification.

A quick basic check would be to tune an FM station, run an RCA cable pair from the audio output for a tape deck (see the picture at the link) to an analog audio input on your TV. Select that input on the TV and you shouls hear the FM station, or anything the receiver is configured to play. If it's silent then there is no audio signal circulating in the receiver to get out to the amplifiers.

Check to make sure Multi-Channel input is not selected unless that is what you're listening to as it bypasses all other sources analog and digital EXCEPT the tape; and check any Mute or Zone Controls, too.

If you hear the program on the TV but not through any attached speakers, then the amplifiers are all disabled for some reason. The click I asked about before... when you turn it on does it get a click about 5 seconds later. That would be the protection circuitry turning OFF to allow the amplifiers to function.

I notice it has a Tape function. Make sure it isn't selected as it assumes a tape deck or processor is attached and will only play back what would be coming FROM the tape deck or processor. On my Pioneer receiver it also disables any digital signal processing.

Sometimes when I'm watching TV with the remote on the seat someone moves and something bad happens. It's always some unfamiliar button that gets touched unintentionally. Look over the remote for things like MUTE, Multi-CH, Tape.

Nice write-up.

On page 6 of the manual it states you should use a powered subwoofer and the unit provides a sub output on the rear panel for it. The message from the amp kicking out is that you're not going to get away with your workaround.

I would advise you to purchase a nice amplifier (2-channel bridgeable or single channel) for the subwoofer. That way you'd be sending only LFE signals and your receiver has provisions for adjusting its volume relative to the rest of the channels. I use a nice 5-channel Carver for my 3 subs and both Rear Surrounds.

On eBay I see what I would get if I were you - a Carver M-200T (120W x2; 300W bridged). I have one.

Yes, there are relay type switches associated with those outputs. Your RX-V1 is not dying.
Just plug a pin plug in and out of the dead channel to bump the switch. You will hear the speaker
come on. If it doesn't come on,do the plug jack in an out of the pre out again. It will come on.
You can use the test tone to check all channels and rebalance volume levels. You are making the
pre out connect to its power amp. It seems the problem got better when activating those switches. Most likely a cleaning issue. You can also jump the mains and center, and there is also
a modification to jump all channels. I bought my RX-V1 very cheap because of this and love it.
Of course outboard power amp would solve all, but getting this reciever to connect to it's own
power amp has been thrilling as far as bang for the buck. I do use the front effects also, and like
them. It may seem like a pain, but it is worth it to get those channels going.

SOURCE: can I mix 6 and 8 ohm speakers?

Most Yamaha HTR's are high current receivers so setting the receiver to 8 ohms and running the 6 ohm speakers shouldn't be a huge problem. I wouldn't crank the volume though if i were you but at a decent level you should be fine.
