HI please help, I am new to all this, I have a double cd player, a four channel mixer and mini disk player all in a flight case. My amp is in a different flight case
(not sure that this has any relavance to my problem) The cd and mini disk sound good through the system.

When I conneect my karaoke player up the sound is very poor ( some interferance, even when the cd and mini disk players are not on) the sound is poor and the bass is high even when turned off !

I have tried to connect it to different channels with no improvement, I have also moved th TV.

Any ideas or do I need a new Karaoke player ?

Firstly Geoffers, to DJs United.

Feel free to add your own views, thoughts and experiences to any of the existing posts here on DJU, or indeed, start your own posts as you have done here.

You may have tried this already but, try swapping the leads which run from the Karaoke Player, into the mixer. A faulty audio lead can sound distorted in the way that you describe.

Looking at less obvious things to check...some video players have 3 phono/RCA sockets all bunched up next to each other, typically a red, a white and a yellow. If you accidentally get the Red and the White leads mixed up, it doesnt matter too much as these are just the Left and the Right audio outputs of the stereo signal, and no-ones going to be particularly fussed, or even notice. However, if you've accidently connected the yellow connector on the video player into your mixer audio in, this could cause some fun...the yellow is usually a video out signal...

Also check any International settings on the video player - eg: everythings on PAL, rather than NTSC (some units can auto-detect PAL or NTSC formatted media, yet can be forced to play either format into your chosen output eg: "Play this PAL disc, but send it out as NTSC" (or vice versa).

Also...try the video media in another video player if you've got a spare one.

Do you get any interference audible though your mixer when the video player is idle? eg: not playing - just "ready"? or do you get interference all the time?

Also check for localised interference - I know you mentioned that you've already moved the TV, but try things like (in this weather) any electric fans (the motors can cause interference), multi-way sockets (nice collection of 240volt wiring) etc.

Other than the above, and you own investigative steps that you've tried already, I'm going to have to suggest the strip-down approach...no, no, dont start unbuttoning anything....here goes...

Unplug everything in the room. Even extention leads out of sockets.

Plug the video player straight into a wall socket - all to itself. Unplug all mics or other inputs to the video player.

If the video player has a headphone socket, plug in a pair of headphones and listen for the noise, both before playing a track, and during. anything audible?

Try pluging the video player into a TV (with sound) eg: via a scart or coax lead? any sound problems?

Then try adding the mics back onto the video player (if its got Mic inputs on it)...any nasty noises?

If alls going well up to this point, try pluging the player into your mixer, adding a CD-deck, etc,etc,etc slowly building up to the "normal" system again - noting when (if) the noise appears.

First, have a can of Red Bull, you'll need it after ready all that lot.

Good luck and keep us all informed about how you get on eg: "The noise starts when I...." or "I found out that the humming noise was a trapped wasp.... "....


once again.... Welcome to DJU.

hello and welcome......


try putting an audio CD in your karaoke machine and connecting it to the mixer as if it was one of your CD player or mini disc using a lead that you already know is working.....


this will give you a good starting point and help you work out where the problems are....

Also has the Karaoke machine got its own headphone socket, if so listen to a disc without connecting it to anything, it may be the machine at fault, although I would tend to agree with the others first.

Hi

Try the above and let us know what happens!

youngster.

Has this been resolved?

Hi,

Thanks for everyones help and advice. sorry i have not got back sooner but have been working some long hours.

I have not tried it on my full system, just with my head phones it seems that the problem was a multi socket in the flight case, close to where all the conections go in to the mixer and also the transformer from my lap top !

Thanks again for all the help.
