Question about JVC MX-K30 CD Shelf System

1 Answer

AUX. Problem: sound cuts. and weird effects.

When i plug my mp3 player or anything in the auxiliary RCA ports, the sound skips like, i have to move the wires to make it ok, then after a bit, it only one speaker works... I also have putted tape on the connecting wires reom my mp3 to the ports, and it doesnt work... And, sometimes, the system volume goes up by ITSELF or down by ITSELF. once, it was during night, it got to MAX. all my family and neighboors were waked up because of it.

    I have a very similar problem with a different JVC system. What's the best way of minimizing the chances of getting electrocuted (aside from unplugging everything first obviously)?

Disassembly Required Ok for whatever reason breaks on the printed circuit board have occured. Expose the contact points of the rca ports. resoldering these spots on the pc board will do the trick. 'HINT' resolder all contacts, there should be 3 or 4. As for the volume check for dirty residue below the surface of the switch face(s) and or increase tension spring found below switch face.

How do I use my mp3 player with my stereo player? I plugged the adapter cord into the earphone hole,no sound came out of the player


Hello

When you plug the adapter cord into your earphone hole make sure that your stereo player is set to auxiliary mode( AUX mode).If you do not set it to auxiliary mode you will not hear any sound,also make sure that the other end of the adapter cord is plugged in properly to the AV input (not output of the stereo player).

Hi, see page 205 of the manual:

Just plug your player into the RCA inputs and press "DISC MS" until "AUX" appears in the display.

Jensen cd 2610 aux input has little volume


first of all the rca jacks in the back of your radio are for plugging in an amp, not your mp3 player. there should be an auxiliary jack(looks like a headphones jack) in the front of the head unit. if there is no auxiliary jack in the front then you will have to go buy a new head unit with an auxiliary jack.

Aux input for sony car stereo (cdx c 5000r)


For Sony Stereos, you will need to get what is called a Bus Converter. The RCA ports you are trying to use are for a CD changer or alternate device like satellite or HD radio, and those have to have some sort of frequency signal to even be selected. You can find a Bus Converter that will allow you to use this as an Auxiliary input. The device you are looking for is called a Sony XA 300, and it will allow you Two extra Aux Inputs, I believe.

MP3 player over my car speakers?


Try from both ports on your Insignia and make sure you've turned the volume on it all the way up. On the car stereo, make sure the source is set it auxiliary (usually AUX-IN). Also double check your cord isn't damaged and plugged in all the way on both sides.
