    Hi PLEASE Help!!!!!

    I am using various Yamada dvd players on a karaoke set up going out to pubs and clubs, I have tried several players, and they all work well initially but after a few weeks the audio sockets on the rear of the players start to fail.

    I go out of the red and white audio phono sockets on the rear of the dvd players to a sound desk and then the signal is amplified and goes out to our Speaker system.

    Basically after a short time of use the sound deteriorates to such a level that it is only coming out of one side and also there are loads of crackles and interference and you can get virtually no volume.

    I have tried changing the audio cables, the channel on the sound desk, using the scart out instead but to no avail. All the other audio devices work fine through the desk including laptop and mini disc players.

    After seeking some advice locally we were advised to move the players out of the stack of other equipment as it may not be shielded enough to sit with loads of other electrical equipment, but again this worked for about 60 seconds and then slowly deterioated to as bad as before. This week we purchased another new player and set it to the side of the rest of the equipment, but although initially looking ok, this had also gone dodgy by the end ofthe night.

    Please can someone help, we just cant figure out why this is happening.

    Many thanks

    I dont think ill help uch, just two points id like to make, which you are probably aware of.

    1). Stacking of components is not recommend for numerous reasons, not least the chance of disruption and/or over-heating.

    2). Connecting, removing, re-connecting, removing etc phone cables from any source is not recommended. I know that is difficult for what you are trying to do, but the connecting and removing can actually damage the sockets of the phono inputs/outputs. I hope someone here has a solution for you, just giving my input ;-)

    That's bizarre eh? I have a lot of Monster interconnects and you almost need pliers to get them on & off... you think you've damaged the outputs on the DVDs? Hmmmm - well, it doesn't seem cable-related.
    You might have some kind of grounding problem, Satan's own ground loop or something like that. You better re-engineer your rig, with an eye on clean power supply and distribution, careful grounding, heat production and dissipation, impedance matching, EMR, RFI, what else? Dunno.
    There's something funny going on there.
    Good luck; let us know.
