Subwoofer heard when only B speakers selected

I have my B speakers hooked up in my basement to listen to music (L/R stereo only) but when I have only the B speakers selected and put the stereo mode on, sound still comes out of the subwoofer (which is upstairs). Can anyone tell me how I can have ONLY my L/R B speakers active without having to unplug my subwoofer?

Re: Subwoofer heard when only B speakers selected

This is really weird. Normally, the subwoofer must be turned off when you turn on B speakers. But, hold on.. I have recently tried to do the same thing as you do, and the result is the same as yours. The problem is that you have to turn off A speakers completely when you activate Bs. If you have an A/B Speakers switch, first push the A to turn them off, after that press "B" to listen to music downstairs. I hope it works.

Plays only mono when listening to music

I lot could depend on how the music source has been connected to the receiver. If you are using a stereo CD player then you may need to check if it is configured to send audio in stereo mode and not mono. The input source selection for the audio is given in page 26 of the manual.
You can go to the setting menu in Receiver and configure the speakers settings according to which ones you have installed.
Also refer page 25 in the manual to over ride speaker configuration if it is not showing correct.

All the speaker outlets seem to work fine, except the fronts, all will work, but if i plug the fronts in, all the sound then tends to just fade away, and then i have nothing, no sound. i can't figure...

I would:
1- First make sure you are properly testing using a reliable source, such as a CD Player or itunes. 2- Make sure the Listening Preset is not on Dolby Pro Logic. Make sure it is on Stereo mode and see if the problem persists.
What usually happens is that when listening to 2ch (Left and Right) Audio such as Television or Music and Dolby Pro Logic is on as a preset, Dolby Pro Logic analyzes both Stereo tracks, tries to detect the voices (center channel), ambient sounds (surround and fronts) and processes the signals into a 5.1 or 6.1 System. You tend to get a fading effect when Dolby Pro Logic is selected and listening to an old VHS, DVD or even music.
To remove a preset, make sure you select the Stereo button at the bottom left of the remote to pan through the options.
Hope this helps

I have an ONKYO TX-SR606 receiver and I am trying to listen to FM radio using more than just the center channels. I have gone through the setup screens for the tuner and only Analog choices are available....

In reality the correct way to listen to radio or any music source for that matter is in 2 channel stereo. What this means is that the front left and right will play and also the subwoofer. If you absolutely want all your speakers to play while listening to fm, than press the Multi channel button and set it to direct, or any other sound field that you may desire.
Good Luck

Rear speakers are dead, never got them to work. Changed front to back and rears work so speakers and wireing are good. Is it possible that because I did not hook up a center speaker this is the problem?

if its a 5.1 channels it means 2 front speakers,2 rear speakers or either the center speaker or the subwoofer.try to hook up either center speaker or subwoofer.

No Subwoofer sound with pro logic on TXSR503

When you are playing cd,s set your amp to stereo and the sub should work,prologic should never be used for playing music as this destorys the sound stage,if you are useing small speakers make sure you have set the size in the setup menu and the cross over to about 80hertz.

Hope this helps.

No sound from back speakers

Remember the rear speakers are called surround... Did you select surround on the unit? if it says stereo then you will only get fronts, select surround to get the rest.

Hi Linda,

It is showing two because the source of the sound that you are listening is probably stereo only thus only two sound comes out. You could try to change the mode to 5 channel stereo or prologic or dts-6channel mode in the surround mode to hear your sound in all 5 speakers. best thing to do is watch a dvd which would use all 5.

Regarding a/b yes if your receiver supports it which i think it does there should be place for it in the back of the receiver.

good luck
