Question about Onkyo TX-SR502 Receiver

1 Answer

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.

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. ^_^

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.

Rampage BA-100 200W amplified subwoofer

Actually. I don't think you have to wire a remote switch from the radio to the amp on this product. This powered subwoofer supposedly has automatic signal sensing turn-on circuitry. I have the same problem. So I think I'll try to just hook up the power (to the battery), ground and the + / - speaker wires to one of the back speakers in the car and see if that works.

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.
