Question about Onkyo TX-SR502 Receiver

Open Question

No apparent sound from subwoofer preout

Here is what I have done to troubleshoot.
I made sure that "A" speakers were selected (sub does not work on B). I made sure that the subwoofer setting in the speaker config was set to yes. I checked the decibel level setting. I connected the subwoofer to an older receiver I have and it worked. I connected an older subwoofer in working order to the current receiver and still no sound. I reset the receiver settings to factory defaults and started over again. I made sure that "A" speakers were selected (sub does not work on B).
If this is in fact a problem with the pre-out, are there any "simple" solutions. This product is no longer covered by factory warrenty and I was given a $150 estimate from a local repair shop. For that price I would just put it toward a new one and open this one up and tinker around if you have any suggestions. Much appreciated!

SOURCE: very low ouput from subwoofer preout

Onkyo to Onkyo, sub/receiver, problem fixed by inceasing volume on receiver. Seems the sub audio input does not pick up LF's below a certain output level from the receiver. So, guess I have to live with that. I only hope my nieghbor in the apartment below me can too!

Where should I plug in my sub woffer

There should be two jacks on the back that say SUBWOOFER in the "preout" section of the back panel that is directly above the speaker jacks. Either of these jacks should work for your sub hook-up. Also make sure that you set your front speakers to small in the speaker setup menu, otherwise there will be output to the subwoofer jacks.

Cant get bass, fuse is fine

You don't say if you've configured the Receiver to know you have a subwoofer (under Multicontrol - SUBW YES). Unless it knows about the Sub it won't send anything out that single "preout". You can get an RCA splitter to run that single output to both inputs in the Sub.

Just as an experiment, temporarily run one a pair of cables from the REC OUT to the Sub's inputs and tune an FM station to prove the Sub amplifier is alive. If it's still silent, it's dead. If there is sound (muffled) you need to go back to the Receiver to figure out why the Sub Preout is signal-starved.

No sound from Sub Pre-out on Onkyo TX-SR606

Also, it could possibly the preout terminal itself that is not working. One way to prove that is by transferring the subwoofer cable from the preout and temporarily transfer it to the tape out section. If it ouputs sound from there, then that means the speaker and the cables are working fine and it's just the preout terminal itself that is not picking up anything. ^_^

Have he KEF 2005.2 Speakers and I cannecting to the DENON AVR 2802 Amp. All Satellite speakers sound OK but there isn't ny sound from Subwoofer. I don't get he System Setup display on the Amp screen...

Run a phono cable from the monitor out on the back of your amp to the tv then go to that input on the tv and then go to the setup menu on your amp ,also make sure you have the sub cable pluged into the sub preout and not the 6channel input.

Hope this helps.

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.

Onkyo 805 sub hook up problem

Talked to tech support at Onkyo and there seems to be two (2) places you can hook your sub up to. I placed mine in the wrong slot. So please double check where you placed the sub connection.
