Question about JVC RX-770V Receiver

1 Answer

No speaker sound

I have recently moved. I am now attempting to set up my stereo and can hear sound out of the center channel fine but can't hear anything out of the left or right speakers. I have checked to make sure the speakers do work, but they won't make any sound when hooked up to the receiver even in test. What am I doing wrong???

Re: No speaker sound

Check the 2 buttons under the source selector knob they are labeled A and B check to make sure both are not pressed in just the one you have your front speakers hooked up to

No sound out of the pioneer vsx-1121-k

Try removing all the speaker and the HDMI connections; then use a headphone to listen to music from the tuner or a CD in stereo mode. Better in direct mode. If you hear your music correctly the receiver could be working correctly. If no music is heard, you may need to have it repaired professionally.
If you can hear music, connect the main FL & FR speakers and verify you can hear music that way, without the headphone connected.
If you can hear music that way, connect the center and rears. Try a mode that uses all channels to verify all sound channels are working.
Then, and only then start adding your HDMI connections.
Good luck

Some DVD's sound fine whilst others have background sounds but no voices. I do have an old model TV that has mono sound.Would that cause it?

" Some DVD\'s sound fine whilst others have background sounds but no voices. I do have an old model TV that has mono sound.Would that cause it? "
I wrote a short article for someone who had a similar problem a few days ago.
I will edit it for you so that it fits. Here it is.
Your DVD player should have output connectors in the back of it to plug your amplifier or receiver into. If you have a Stereo system (no surround sound speakers, or front center speaker) connect the DVD Audio Cables on the back of the DVD player to the STEREO (or MIXED ) Output Jacks. If it is connected to the Left Front and Right Front jacks of the "Surround Sound" output jacks instead of Stereo(or MIXED) then the dialog will be sent to the CENTER channel output. If you have no center channel speaker you will not hear it. Thus no dialog.
NOTE: In your case for the TV that is mono, here is the solution.
1 Connect a stereo pair of RCA cables (red and white "male" connectors at each end) to the Mixed or Stereo Output of the DVD player (NOT ANY SURROUND OUTPUTS).
2 Purchase an RCA type "Y" connector that has 2 female to a single male connectors on it. Walmart about 3 dollars.
3 Plug the single male plug of the Y connector into the back of the TV set's single mono audio input.
4 Connect the stereo RCA pair from the MIXED output of the DVD player into the Y connector that is now on the back of yourTV.
5 Run your yellow Video output from the DVD into the Back of the Set's yellow input.
That should do it. The sound should be clear and correct with dialog, effects and music.
Hope this helps,

Yamaha RX-V365 Receiver when I hook up my center channel it is not audible at all. The R and L speakers work fine when they were located in the FRONT A and FRONT B terminals, but when I moved everything to...

With what signal did you try? Maybe your signal source (DVD/TV or radio) didn't contain any sounds for the center channel.
Go to the Setup menu, Speaker setup / Manual setup and find there item called "Test tone". It will output a test tone to each speaker individually (you will see on LCD which speaker is being tested at each moment). If you will hear a sound from the center now, there is no issue and center is working fine, just your source didn't contain any sound for the center.

If it doesn't work, then either you have faulty cable, faulty speaker or faulty center output of the receiver.
- Try connecting the center speaker to different output of receiver (this will test if speaker is OK).
- Try connecting working LEFT speaker to left output with CENTER cable (this will test if cable is OK).
- Try connecting working LEFT speaker with working cable to the CENTER output (this will test the output of receiver if OK - but use the Test Tone from Setup).

No sound of voice, only surround sound

If you do not have a center channel speaker connected, then in the reciever setup menu for speakers, there should be a selection for center channel that says something like either yes or no. I'm guessing it says yes. Then you need to select "no" so that the circuitry will direct sound specified for the center channel to be reproduced through your front speakers.

One channel not working (no output) when useing various modes


I had a similar problem, now to be honest there is quite a couple of things that could be faulty. I dont know which cable you are using between the source and the amp, but i am using RCA to mini jack.

I had the same problem that my tuner on amp played through all channels dvd as well, but as soon as i hook up the amp to my computer only some of the chanels played.

I found out that there is actually mono and stereo versions of of that cable thus, if you use a external source and channel it trough the amp with a mono cable, only some channels will be playing.
If you use a stereo cable both channels will work.

The other problem could just be a simple setting on the amp itself.
Usually you can set the number of channels you want the amp to be set on. It is very simple, locate this function an try every setting untill you hear that all channels are working.

It could also be an "ic" on the heatsink of the amp which overheated, if you open up the amp you will be able to see it instantly. This will explain the slight sound you manage to hear.

My advice is to try the first and second sollution and as a last resort send it to a repair shop or if you still have warrenty send it back. I doubt that it is a hardware problem on the amp itself.

Please rate this.

Best regards

I have Bose 901 speakers attached to a Denon receiver, but the sound is muffled with poor dynamics. The speakers has a box which is supposed to be in the signal processing loop. The reciever is supposed...

I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.

There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what you want to do and it works great!

A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.

Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Write off the Tape Out as an input if you use it to extract the Front L&R channels. DO NOT monitor it or you'll chop the 901's out of the signal path AND kill any digital source audio in the receiver.

Center speaker still not working :(

all your speaker channels are working so your problem lies with a setup fault. when you watch tv you are only feeding a stereo signal into the amp. you need to select the internal surround sound generator. you need to select either the movie or surround function. the unit will convert the stereo signal to 5.1 channel surround.

Back speaker sound

Why would you only hook up one speaker for the rear channel? in 7 channel stereo, all speakers have 100% signal sent to them as "stereo" in Dolby digital, rear speakers are for "effects" not dialog. like a plane flying past you or a car driving by, that's when you hear a rear speaker. It also needs to be placed behind you, not next to you or in front of you. Unless you are using zone 2 & 3 the receiver's surround back will work. if you only have left,right,center,sub & rear; the rear speakers should go to surround speakers not surround back. If you still have questions, post a comment and I can explain further. Hope this helps

Center Channel Audio

There are probably several sound settings on the receiver :
Dolby surround , stereo, theater, SACD etc.
Try another setting other than the one you have
