SOURCE: Subwoofer not working

you have to reset the receiver, i had the same problem, works now, it's great, should be in the instruction booklet. I think it was, hold the power button while you disconnect it from the wall, not too clear but check the booklet in resetting system

SOURCE: Subwoofer Connection: Speaker wire to Mono RCA

The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.

  1. Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
  2. connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
  3. make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
  4. leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.

You can even now turn off your subwoofer / adjust the volume easily now!

SOURCE: Yamaha RX-V1200 subwoofer connection to Mirage BPS-150i subwoofer

just connect your subwoofer mono RCA to your amp sub single out rca connector. you do not need to megre all those 4terminals into one. in fact internal circuit of those 4rca are merging inside to one since the sub uses only a single amp. 4inputs was meant for sources with multiple sub out

SOURCE: 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. ^_^

SOURCE: My Onkyo tx sr502 quit producing sound?

I have the same problem.It's definitely the pre-amplifier board (board with speaker terminals).I did not quite nail the exact component yet but I replaced with a working one and got back sound output.

Why is my deck not controlling my subwoofer level?


If your Sony receiver has a separate sub output, it probably has a fixed level for application to a powered sub. Your mono amp can only boost the fixed signal level it receives from your receiver. The receiver can't drive that mono amp harder

Do i need subwoofer with power or without power and how to make subwoofer sound on ??? just send me simple setup please ? cheers


Depends on your source and its amplifer complement. Some can drive a subwoofer directly while others just produce a Line Level subwoofedr output for use by a separate amp feeding a subwoofer or self-amplified sub.

The setting up of the source to produce a subwoofer output is totally dependent on its design. Generally, you have to 1) tell it you have a sub, 2) define how bass will be routed or shared among your various speakers accordingto their bass-handling capacities, 3) using test tones, set the relative ludness and crossover settings so you have a uniform sound field.

Name the electronics and get a better answer. Or refer to its manual.

Why aren't you looking at the sub for the reason? It may have the crossover set too high.

If the sub is loud enough during level setting, look at receiver settings, otherwise it's the sub amp.

Overloads with volume a third od the way up,i have 2 12 inch cerwin vegas hooked to it


fan_of_tony,
There is not much info in your question to properly answer it but here are a few things.

1) The VSX-D307 is a home receiver that is rated for no less than a 4 ohm load. If you have two 12" 4 ohm CV subs on the same channel and they are in parallel, that would create a 1.7 ohm load which would easily cause the problem.

2) If you have one on each channel connected along with speakers that are for you mids and highs, the way they are connected could be reducing the resistance load the amp will see which would easily cause the problem.

3) If you have one on each channel and no other speakers the problem would be simply that your speakers can use more power than the amp can produce. Thus you are able to raise the volume of the amp passed it's maximum output which would cause the amp to clip and the amp will go into overload protection.

4) Your receiver has an 8 ohm rated amp. Which means it can run at 4 ohms but the amp will produce more power at lower volumes on the knob setting and will max out at lower levels than if you were using a 8 ohm speakers.

In short, CV's can use a lot of power and your receiver, regardless of advertised power levels, cannot give the speakers what you are looking for in sound levels. Buy a larger dedicated amp for the CV's as the clipping from your Pioneer receiver is doing damage to your CV's. Your speaker's can hear the clipping before your ears can so damage will start to occur before your ears can hear the clipping.

Subwoofer doesnt work


New sub (never worked) or sudden failure (after it used to work)?

Type of sub? Has to be self-amplified (active).

Have you read the manual? You can find it on Retrevo.com. Just register and download it.

Did you define the Sub properly (SWFR or BOTH) in the SET Menu (page 42)?

Did it produce the test tone (Page 21)?

If all of these are done and the sub still doesn't work, maybe the sub is defective. Connect a CD player analog output to it to prove it can produce sounds.

Have 1 subwoffer need to hook it up to a 2 channel input


I must assume that you have a "Sub" output from the receiver that you are using. If this is a dedicated Subwoofer that doesn't have it's own power, you are set, all you need to do is use an RCA cable from the Receiver to the Sub. If this is a dedicated Sub without power you will need an appropriate power amplifier to amplify the signal to the Sub. If this is only one Sub you may search for a Mono Amplifier to save money in your search. The connection from the Receiver to the Amp is the same and from the Amp to the Sub is with a wire that is usually 18 Gauge "Zip cord" unless the Sub has it's own cabling. Place the sub in a corner to maximize the power output and move it away from the corner to smooth the output until you like the way the sound works with the main speakers. If it is too loud or too soft most A/V Receivers provide a way to adjust the volume of the Sub. Enjoy the sound when you get it setup the way you like it but don't blow out the neighbors.

Only Direct sound works good, and only two speakers


Some sound fields have reverberant effects that need adjusting so the levels become audible, such as in "stadium" mode. While playing one of these sound fields, navigate through the speaker setup menu and make adjustments to the "effects" percentage, and levels. Be aware however, that only in 4 channel stereo mode will your surround speakers produce sound 100% of the time. Also, in any form of Dolby Pro Logic mode you will hear more sound from the surround speakers originating from stereo source material than from monoaural material...example, a television station broadcast in stereo versus mono.
