JVC AX-33 Stereo Integrated Amplifier - very little sound!

My amplifier is having some problems!

I can turn it up to full volume and it is still very quiet, i have tried the speakers on both channels and i have the same problem. I know the speakers are ok because i have tried them on another system.

Any suggestions would be appreciated.

    I have a AX66 hooked to a RM20 and have the same problem, I can hear a very faint sound and have a checked all the routing which seems in order but no loud sound. BTW I'm a AV engineer with Barco 12K and 18K, Sony Anycast and Folsom weekly hookups for AV shows. I do know my way around and this thing did work and now it doesn't after I moved it to another room. What is the button pattern?

Hi xaser

Check that someone has not turned on the tape monitor or mute. Both of these may cause the problem. Is there alot of noise with the sound you are getting when you turn it up?

Hi all, A possible solution for some situations.

A friend gave me his old stereo amplifier (kenwwod kr595). All worked, except that even with Volume full, there was very little sound when any source was connected to any of the rear rca jacks (ie. CD in, Tape in, etc.).
However one pair of the rear jacks played the sound back perfectly (ie. with Volume dial at normal setting). This pair was labelled "Adaptor in".
I googled for a manual, and found that for the sound to play back properly through the other jacks, the "Adaptor in" pair, had to be connected to the "Adaptor out" pair (next to it). This had been made that way, to allow that an Equaliser could be connected in and out of the chain.
The manual said that if not using an equaliser, these need to be connected another way, which I quickly achieved with another short regular rca to rca lead (same type used for connecting everything else).
After this anything that was connected to the other "in jacks" played a proper sound level.
I did notice though, that the sound quality was not quite as clear and strong, as when I connected a source directly to the "Adaptor in" jacks, but would still be fine for most folks.

I have a A-X2 JVC stereo integrated amplifier and want to know where I could get a copy of the user manual

Look to the JVC website. Hopefully they will still have it, as JVC has been out of the home audio business for a decade or two.

I have a JVC ax 220 amplifier and there is no sound coming out at all.

Is the receiver even turning on? If it is, listening carefully to the top cover, with the room quiet. Do you hear 1 click, or two?

If you're interested in having your JVC repaired, please visit my website at You may contact me there. Thank you.

My su-g95 technics Stereo integrated amplifier wont play any noise. and when i adjust the volume it makes a popping/crackling noise. i am 100% sure all the speakers were hooked up correctly.

Well it sounds like your amplifier IC's are working correctly since you are hearing that pop. I have the same amplifier and every 10db increment it pops. Have you tried every input? Possibly try starting at a low volume, plug an RCA plug into CD or any other input, and touch the center prong of the other end of the cable. You should get a 60hz hum if your in the USA, otherwise it will be 50-55hz. Regardless it should make noise.

Hello i was wanting to know if i could hook up my AX-596 amplifier to my Yamaha HTR-5860 reciver

I assume you want to slave it to the receiver and drive some more speakers with it.

Connect some RCA cables from whichever channel pre-outs you want on the HTR-5860 to any input on the AX-596.

Set the AX volume to something sufficiently high, run through the HTR's speaker level setup and match the AX volume to match the channels on the receiver. Then leave the AX's volume alone.

If you just want the AX to have access to program sources of the HTR, run the RCA cables to it from one of the VCR1 or 2 Out (but DO NOT select whichever one you use via the front panel). These are not affected by the HTR's volume controls.

JVC AX-66 Integrated Amplifier seems to be muted?

You need to have a jumper between the 4 standalone jacks on the right side of the column of stereo connectors. A stereo RCA cable would work for this.

The volume will not turn down

Do the volume controls on the stereo itself (not the remote) work? Try using a universal remote to lower the volume.

My JVC AX-33 is giving almos tno sound

My experience tells me that after an amplifier had been used for quite a while (more than 5 years), the contacts (on any button) wear out and become loose. If you try to press to engage, you will notice that the sound will come back on. The most frequently touched/used buttons are the one that wear out easily. These contacts should be replaced with original one. Substitute parts won't last long.

Amplifier will only put out "faint" music, etc, even when the volume is turned all the way up

This may sound silly, but please check to be sure that the tape monitor switch in not engaged. Update this if that is not the problem.
