I am getting no sound from sub. The turns on, but so sound. I have connected to two different receivers to verify it isn't the receiver sub output.

Could be a number of things try each and test!

1. Make sure the MUTE function has not been activated.
2. Try turning up the volume level.
3. Check that there are no headphones connected.
4. Try setting the Audio/Video (A/V) receiver to a different Surround Sound mode. IMPORTANT: Verify that the source you are playing is encoded with Surround Sound audio. If not, the audio will be very difficult to hear using a Surround Sound setting. Set Surround Sound to OFF when playing a source that is not encoded with a Surround Sound signal.
   
5. Check each speaker to make sure they are properly connected to the A/V receiver.
6. Perform a Test Tone function to verify if the speakers are working correctly.
7. Verify all external audio sources are securely connected to the appropriate inputs on the A/V receiver. NOTE: If the audio is being sent from a television to the A/V receiver, then it may be necessary to disable the internal speakers of the TV or set the audio output of the TV to FIXED or VARIABLE. If the audio output of the TV is set to VARIABLE, then you will need to increase the volume level of the TV.
   
8. Make sure the correct audio input is selected on the A/V receiver.
9. Confirm what type of HDMI devices are connected to the A/V receiver and then check the following:
   
   
   1. Test each one of the HDMI inputs on the A/V receiver to confirm that all of the inputs for the A/V receiver are working.
   2. Try a couple of different HDMI cables to verify there is not a bad set of cables.
   3. Unplug the video source from the A/V receiver and connect the source directly to the television. If there is still a problem with the audio, continue to the next step. If connecting the source to the TV corrects the sound issue, service will be needed on the A/V receiver.
10. Verify the DEMO (demonstration) mode is not active.
11. Change the ATT (attenuate) setting. NOTE: The procedure to change the ATT feature varies by model.
    
12. Reset the A/V receiver back to factory specifications.

Try turning up the sub out-put, in the Receiver settings

Hissing? How loud? A sub isn't even capable of making high frequency sounds at normal volumes.

The Pioneer manual would tell you how to enable and test the subwoofer output.
Page 17 and the MACCV procedures on Page 33 (auto) or 43 (manual)

Have you looked at the manuals?

If the unspecified sub isn't self-amplified it won't work with this receiver.

If it IS self-amplified you still needt o set up the receiver to run a sub.

grady66,
We will start with the easy one, Phase. The phase selector is a setting that can be adjusted by sound; which one sounds better? Either one will work fine. It's mainly for situations where the sub enclosure is located at a distance or behind the listening area. The 'in and out' crossover selector and the input from the receiver goes together. The 'in and out' crossover selector is asking if you want to use the internal crossover to block the bass from getting to the satellite speakers. Most home surround sound receivers only have the one sub out and most subs have both left and right inputs. When there is a single signal being fed to the sub you use the subs left input or buy a splitter and send the signal into both left and right, but either way will work equally the same.

There is two ways to connect the speakers to the receiver.

1) Cross-over 'In': you connect the output speaker wires from the receiver to the speaker inputs on the sub and the speaker outputs on the sub to the satellite speakers; the sub will get its sound from the input speaker wires.

2) Cross-over 'Out': you connect the sub to the receiver using the receiver's single sub out, then connect the satellite speakers directly to the receiver's speakers outputs; in this configuration the satellite speakers are given a full range of signal including the bass.

I have used #2 with the same system and had great results.

Hello Fixya customer,

Thank you for your question.

Please check that the sub woofer and RCA cable are working by removing the RCA wire from the Sub woofer output of the Onkyou and touching the center terminal of the RCA plug. You should here a hum when it is touched.

If you get the hum, then the next step is to "Clear" the Onkyo by holding down the "VCR and Stby" button until you see "Clear" on the display. Warning, this will clear any settings special that you have made to the receiver, but will get you back to the Factory settings.

Lastly, check various sound fields, and the Sub woofer volume setting, if you still do not get sound, please have a Onlyo service center verify the output.

Thank you using Fixya.

NOOOOOOOOOOOOOOOOOOOOOOO! Never connect speaker outputs to anything that looks different, like RCA connections. Can you say crispy critter?

Your receiver sounds like it won't send specific Subwoofer of Low Frequency Effects information to the Sub so we're cheating by adding a sub. If you named the model of each we may have a better shot at naming the output you need to use.

I'm curious. How did you have the old passive sub working?

Basically what you may have to do is feed (probable) full range audio to the Sub using an RCA splitter to combine the L and R outputs found, oh, at any Tape Output that you're not using. The Sub will only reproduce what it can. The presence of higher frequencies won't bother it. If it has its own volume control you'll be able to balance its volume with the rest of your speakers.

Follow the steps below to troubleshoot why there is no sound:

IMPORTANT: If model-specific information is required to complete any of the steps in this solution, refer to the operating instructions supplied with the product. Manuals are available online in the Manuals/Specs/Warranty section of the Sony® eSupport Web site.
NOTE: Because each of these steps represents a possible solution to this issue, check the sound after completing each step.

1. Verify that the Audio/Video (A/V) receiver is set to the correct function or input mode.
2. Verify that the A/V receiver is not in the demonstration mode.
3. Check all speaker connections to verify proper connection.
4. Depending on your model unit, select the main speaker output (A or B) that corresponds to where the main speakers are connected. IMPORTANT: If the main speakers are connected to speakers A on the A/V receiver, the speaker output must be set to A for sound to be reproduced.
   
5. Run a test tone operation to test the speakers if your A/V receiver has this feature.
6. Verify the cables from the source component are connected properly to the A//V receiver.
7. Connect the component to a different input on the A/V receiver.
8. Tune the A/V receiver to the new component input.
9. If the issue is still not resolved, replace the A/V cable between the component and the A/V receiver. NOTE: If all speakers operate using the different input, then the first input on the A/V receiver is not functioning correctly.
   
10. Connect a working speaker to the speaker output on the A/V receiver that is not working.

If the issue is still unresolved, service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer.

Subwoofer needs to be enabled through menu on Yamaha. LINE OUT might be turned off or Subwoofer volume set to low or off... (-db level) kinda thing...speaker wires are usually always live etc...

if the subwoofer is on in the reciecer settings then maybe the amp is not getting the signal or the amp is not amplifying
try unplugging the output of the sub then turn off the reciever for a min. then turn it on wait , then plug the sub in
if that don't work then test the sub output with a stereo that has a audio input
also test the subwoofer with a audio output to it( only a positive and a negitive wire for sub)
