Try spraying switch cleaner into the body of the volume control. Sometimes works but if the resist is worn then the only solution is to replace the component.

Check all of your speaker wire connections at both ends for looseness, strand wire fraying/breakage, correct polarity and corrosion. If all are ok, reduce your setting for the amount of bass it outputs.

I have the following setup: AV Receiver: Pioneer


Very common problem with today's receivers. Receivers made today don't have a true preamp section in the amplifier and do not amplify the sound to the extent of an older receiver. I have large 15" front speakers on my system, and have stuck with my 15 year old receiver just because I know that a new receiver will not have the power to drive them well. Many of the newer receivers need to be turned up to 50-60% before you can even hear anything from the speakers.

My sony STR-DE475 has no bass. The bass just went out after running it for 6 hours.


Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.

Hi there. I am trying to get my subwoofer to work with my denon 791 receiver. I have played around with a lot of the settings and cranked up the subwoofer volume on the actual sub but nothing is coming...


It's not THAT easy. First, turn the volume down. We don't troubleshoot with maximum volume.

The receiver has to know about the sub and be configured to send some, if not all, bass t o it, then the levels have to be adjusted.

The manual for the avr791 is here:

http://www.retrevo.com/support/Denon-AVR-791-Receivers-manual/id/23693ag505/t/2/

You're going to need to be very familiar with it.

Starting at page 6 the manual talks about the automatic setup.

When they talk about defining the other speakers as Large vs Small later on, what they mean is not the literal Size, but if the speaker can reproduce bass or not.

I don't know what your sub is so maybe you could refere to ITS manual or find it at retrevo.com

What does the sw level setting do?


hello.. the sw level is short for your subwoofers volume setting .when you use a subwoofer thats powered and connect it to your recievers sub out,this is than a way to adjust the subs volume from your seating position rather than only adjusting it from the back of the sub.. i recommend putting your subs volume(on the back of the sub itself) to midpoint and playing a bass heavy song or movie and adjusting the sub level on the reciever to how you like it.. enjoy

Very low ouput from subwoofer preout


The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
