Maybe one of the audio leads does not have a complete earth shield and until the second lead is connected, the lack of a suitable earth shield produces the 50Hz 'hum'.

If you should connect either of the two the centre conductors to your body, YOU will introduce a similar hum due to your body acting as an 'earth' to that signal carrier.

These are frequently common effects and it may be a good idea to turn the volume level down on the amplifier or even turn it and the VCR OFF whilst you make or break these connections.

Good Luck!

    • 2
      Attach the cable to the RF IN jack on a surge protector and tighten the coupler clockwise.

      Connect a second coaxial cable from the RF OUT jack on the surge protector to the input on the cable box or satellite receiver. If this stops the hum, congratulations: You're done.

      Unplug the subwoofer's electrical cord from the power strip or wall outlet if it is connected to the same circuit as the AV receiver. The amp in the AV receiver and the amp in the subwoofer are in conflict over the grounding of the electrical circuit.

    • 5
      Plug the subwoofer into its own surge protector and connect the surge protector to a different wall outlet than the AV receiver uses.

    • 6
      Disconnect the subwoofer cable from the back of the sub and the AV receiver if all other measures fail to stop the humming. Reverse the plug connections so the plug that had been connected to the receiver is now connected to the subwoofer. Turning the cable around may solve a problem known as ground-loop hum by reversing the shielding wire inside the cable.

here is your answere.... if you have your tv or vcr, or dvd...etc to close it can cause a hum with a "indoor antenna "..... now we can fix this .... move your antena far away as possable from the tv...etc make sure wires are not "tangled" in it, make sure that your source inputs are not grounded, ex 3 prong plug on vcr on tv...etc. invest in a good surge supressor that will " clean your power " ex ... monster cable etc... now you can " ground the system " by using a alagator clip to your "cooling fins" and connect a wire with a loop ring to your outlet that is grounded or loop all devices together and then to ground. if you still have any isues consult a licenced electrician to check your ground from pannel box to meter and make sure the ground is "bonded" to the neutral bar... this should solve your issues....

There are a couple of different ways you can do this but this is the easiest.

Items needed - One set of RCA audio cables (Red/White)

1) On the back of your TV there should be RCA plugs marked as "Audio Out". Connect the RCA cable to these connections Red cable to Red connector and White cable to White connector.

2) Locate on the back of the surround sound system the connections marked "Audio in (VCR)". Connect the other end of the RCA cable to this connection Red cable to Red Connector and White cable to White connector.

Now to get the sound to play press the "VCR" button on the surround remote and you should get the cable box sound on the surround system.

Good Luck.....

How do you hook it up to a vcr ?


there are a few ways , depending on the model and depending on what you want to hook it up to. basic rule is.... output to input. find the audio and video out on the gadget you wish to hook up. then find audio and video in on tv or whatever you hook it up to.... some devices have a few different kinds of jacks on them. rca jacks are the red, white, yellow ended cables.... or you can just use a coax cable.... thats the thicker cable with a little metal wire sticking out the end that screws onto the only thing that it'll screw onto. or theres s-video.... which is also pretty unique because you can only plug it into one thing, but you'll also need to run the rca audio cables ( the red and white ended things) if you use that. so... to clarify... output to input... all ya gotta do is read the back of your gadget and you should be able to figure it out. hope that helped.

Vcr hooked up, no audio


From the VCR to the tv if you have RCA cables its kind of hit and miss where the audio cord goes. Only one of the jacks are for sound but it has to be plugged in to the right input. Audio is usually the white one. Just keep touching it to inputs until you hear sound start to come out of the speakers. Hope it helps.

Connecting an Ipod to JVC TH-M45 System


you can hook up ipod 2 different ways. the one i will use will be with a 3.5 to 3.5 mini plug connection(on both sides of cable it has i.e. head phone jack connection) and then set unit to aux in and that will give you sound from ipod. another way is with red and white audio cables to 3.5 mini plug connection. connect red and white to audio in on back of unit,and then set unit to that source.

Connect tv vcr and dvd player to digital converter box


Yes you can first connect the converter box to the antenna first. Next hook the tv out on converter box to vcr in on vcr. Next hook the vcr out to the tv in and watch vcr and converter box on channel 3 sometimes channel 4.on the actual tv and of course change channels with converter box remote. For dvd player hook it straight to tv with red,white,and yellow cables that come with your dvd player. Then to watch dvd player if it's hooked up that way you have to put your tv on a input like video 1 or input 1. This can be done by using the tv remote and looking for a button that says tv/video or input or source button. This is some common names for that button on tv remotes.

Set up


The red and white plugs are audio - they should go to one of the receiver's inputs.

The yellow plug is composite video - if your receiver has a yellow jack, plug it into the receiver (this will let you switch inputs from the receiver), if not, plug it into your TV.

Same goes for your tape deck, though it won't have a video output.
