Is it wireless or do you use cables to connect the speakers? If using cables, i suggest buy better quality cables. I had the same problem. Usually if the cables are old they won't hold the charge. Good luck

My Pioneer XV-DV282AP home theatre has no Audio output. Every time I put the volume up/down, it keeps on saying HDMI/TV Audio. It only works with an HDMI cable using the speaker from the Television.


The system is set up to output sound through HDMI to the TV. You can change the setting so the sound is sent to the speakers. The process for changing the HDMI output setting is in page 41 of the manual. You want to choose the AMPsetting. I have included a link to the manual and copied the text below.

1. Press SHIFT+SETUP.

2. Use ?/? to select HDMI SET then press
ENTER.

3. Use ?/? to choose HDMI MODE then
press ENTER.

4. Use ?/? to choose the setting you want
then press ENTER.
• AMP - Output Audio sound of the DVD/CD
and USB function signal from this system
• TV - Output Audio sound of the DVD/CD
and USB function signal from a TV or flat
screen TV.

My HT-X20 keeps on going into protection mode after 1 hour then every 5 minutes. What should i do?


Suspect heat.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Hi, I have JVC CA FSY! and it has static noise on speakers but its ok on headphone. How can I solve this problem?


http://books.jvc.com/booklist.asp?Model=fsy1

Choose your submodel.

So the good news is that the amp isn't implicated but an electrical conductor somewhere in the path may be flaky.

Headphone insertion mechanically disconnects output to the speakers. Hence, headphone removal relies on spring-loaded contacts to restore the output to the speakers. Perhaps there is oxidation on the normally-closed contacs. Repeated headphone insertion/removal MAY help wear it off.

Also try swapping the speakers (wire and all) to see if the static follows or stays with the amp channel.

I have this mixwer for domestic use only, swithced it on last night and power is there, but no sound at all, from any channel.Could you please advise,


Make sure your audio source is playing.

Make sure your channel is not muted.

Make sure your channel is assigned to "main mix" (bottom button to right of main volume slider).

Make sure your main output slider has volume applied.

Make sure the cable you're plugging into your "main output" is being plugged into the 1/4" or xlr output receptacle that corresponds with the slider you provided volume to.

You should then put the outgoing cable into either an eq or an amp.

If you're going to an amp first, place the cable carrying the signal from the board into an "incoming" slot on the amp. Run a cable from the output of that channel of the amp to a speaker. Turn on the amp and fade the volume knobs up. That should give you power - provided your board, cables, amp and speaker are working properly.

If you're going to an EQ first, place the cable carrying the signal fromt he board into an "incoming" slot on the eq. Then run a cable from the output of the same channel on the eq to an incoming slot on your amp. Then run an outgoing cable from the same channel on the amp to a speaker. Flip your eq on, flip your amp on, fade up the volume on the amp, and make sure you don't have a gate closed on the eq (also make sure if you have a gain knob on the eq, that it's at least partially providing power). If your board, cables, eq, amp and speaker are working properly, you will have sound.

What provide the picture to your TV? (cable or Sat).
If you use either of these then on the back of the boxes are outputs, Video (yellow) and Audio (red / White). if you put the audio output to your amp you will get sound thru your speaker but will need to select (what ever input choice where you plugged in red / white) the input on the amp when viewing TV.

A better solution would be to place a splitter (RCA so that the audio can still go to TV and the Amp) from each color. So when you don';t want the amp on you still have audio on your TV.

Surround sound help


A few questions... What components are involved? How are they connected? Can you hear sound from the speakers for any other input device i.e. radio, cd, vhs, etc.? I suspect that there is an issue with the way the system is connected. I have the Surround sound output from my DVD player connected to the digital surround sound input on my reciever. I'm using digital coax cable (looks like a "normal" RCA cable), not the optical fiber connection. I had to buy a special cable for the digital surround sound. A normal RCA cable would not work. I don't know why. If you're using a similar connection, that could be your issue. make sure that the output and inputs you're using are compatible. A digital surround sound connection (in or out) can't be connected to an analog connector (in or out). Remember, Digital to Digital with a Digital capable cable; Analog to Analog with an Analog capable cable. If this is not your issue, post back here with more info and we'll see what we can figure out.
