Question about JVC Audio & Video Receivers

I have a model UX-G70 JVC micro system. There is a constant rumbling sound coming from the woofers. When I took it to be serviced they hooked it up and the noise was gone. I have tried changing wall outlets but nothing seems to work. any ideas? Thanks

    RE:JVC UX-G70 micro system

    The noise began before I took it to be serviced. I've tried it in different rooms and same problem.

    Thanks for the info. I'll try the noise filter
    and removing the wireless phone.

Hi,

The "rumbling sound" is coming from an external source (as you suspected since you tried changing outlets). A way to determine is to switch off/remove any other electrical devices that may be attached/connected to the JVC UX-G70 micro system. These may include: alarm clocks, electronic lights (small fluorescent lamps), other audio equipment such as players/recorders, monitor, microphone and others of the sort. You may also want to check your speaker wires are not near or in contact with other electronic noise sources.

Additionally, you can try using a power line filter and see if that will eliminate if not reduce the "rumbling sound". Rumbling would refer to low frequency as against humming which is predominantly AC power lines spillage.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Allow me to expound, the external devices need not be electrically connected but those that are physically near the JVC.

    Hi again,

    Even wireless phones or mobiles can cause interference that can be heard at the speakers.

Subwoofer not working.... JVC surround sound system 778V Subwoofer Part Number SP-PW37-SUB I hear a hum coming from unit so there's power going to it. I hear weak bass thumps with volume turned all the way...


A connectivity check could provide the solution, notice any wrong wire connections on device or any other devices requiring interconnection. The woofer would perform properly when the connections that provide current for woofing are approapiate

important notes
1. Trace the connection from Recorder or sound output to the woofer device
2. The wiring connections should be sound and video ouput into sound and video output into woofer.
3. The connections if any problems would be located at the stereo recorder or device producing the spund and video. Check the connections of wires on the recorder device ensuring rewiriing
4. finally, adjust the equalisers if any the buttoms could have been disbled by master switch hindering full blaster boost sound.

My JVC RX6000VBK does not get the signal from or to my subwoofer.


i had the same problem a few times, they are pretty picky receivers.
first take a look in your settings and make sure none of your speakers are set on large, if they are they automatically shut off the woofer,
2, try the adjust option and crank the bass and throw on the bass boost
3. manually turn the woofer on through the receiver itself
4. try and turn up the woofer itself if is powered
5. try hooking the woofer up to the secondary speaker jacks by bridging it, (positive on left and negative on right for even power)

if none of these options work then the woofer itself may be defective even though it lights up

SA-AX720 no subwoofer signal?


THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.

Sub


Most amplified sub woofers need to be grounded to the output source.If you plug the sub woofer in to the receiver you would use a ground wire from the receiver to the sub woofer there should be a ground terminal on the sub woofer and receiver.

Go to the following website www.servicemanuals.net where you can get the service manual for $17.00, unbelieveable, don't you think? The service manual should help you sort out your hookup problems. Good luck.
