Technical questions for the MPC2000xl and the MPC2000

Unfortunately I am still having problems with the electrical noise... I was going throught the manual and found the following:

WARNING
THIS APPARATUS MUST BE EARTHED
IMPORTANT
This equipment is fitted with an approved non-rewireable UK mains plug.
To change the fuse in this type of plug proceed as follows:
1) Remove the fuse cover and old fuse.
2) Fit a new fuse which should be a BS1362 5 Amp A.S.T.A or BSI approved type.
3) Refit the fuse cover.
If the AC mains plug fitted to the lead supplied with this equipment is not suitable for your type of AC outlet sockets, it should be changed to an AC mains lead, complete with moulded plug, to the appropriate type. If this is not possible, the plug should be cut off and a correct one fitted to suit the AC outlet. This should be fused at 5 Amps. If a plug without a fuse is used, the fuse at the distribution board should NOT BE GREATER than 5 Amp.
PLEASE NOTE: THE SEVERED PLUG MUST BE DESTROYED TO AVOID A POSSIBLE SHOCK HAZARD SHOULD IT BE INSERTED INTO A 13 AMP SOCKET ELSEWHERE. The wires in this mains lead are coloured in accordance with the following code:
GREEN and YELLOW —EARTH
BLUE —NEUTRAL
BROWN —LIVE
As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug, please proceed as follows:
The wire which is coloured GREEN and YELLOW must be connected to the terminal which is marked with the letter E or with the safety earth symbol or coloured GREEN or coloured GREEN and YELLOW.
The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK.
The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED.


Has anybody done this?? Is this my problem?? Is this mandatory?? Please let me know!! Thanks again for your help!!

THAT THIRD PRONG ON YOUR POWER CORD WHICH GOES INTO THE WALL SOCKET IS ALREADY GROUNDING YOUR MPC. WHEN YOU SAY DISTORTION IS IT FLARING UP WHENEVER YOU TURN THE VOLUME KNOB? IF SO IT 'S DEFINATELY WHAT I TOLD YOU THE OTHER DAY.

BETTER YET WHAT DO YOU HAVE PLUGGED /HOOKED UP INTO YOUR MPC? AND IS HAPPENING ONLY WHILE YOU'RE SAMPLING ?

I'm currently not sampling at the moment.. It starts happening as soon as I turn the MPC on and raise the volume on my mixer.. The only connections on the MPC right now are the MIDI cables and a SCSI cable for the Zip drive.. Thanks!!

un hook yor mpc from the mixer. just unplug the main outs and plug in some headphones. if you still have the static you know it's the mpc if not its the mixer or your cables aren't up to par. either way we can narrow this down.

Yo kingofmelody, i' m having the same problem but the only differance with me is when i plug my rca jacks into my mpc i get a radio station !!
thats right a radio station.i know its not the cables cuz they are new hosa
cables, and the mpc was brand new when i bought it so i dunno whats going on there ,but i feel you anger . akai pz

By kingofmelody Tue Sep 23, 2003 3:29 pm
Akai, do you at least know what's causing your problem.. I think I would feel much better If I knew exactly what's wrong with my scenario, but I have no idea.. I thought about taking my MPC to an authorized repair shop, but I do not want to go all the way to New York, NY and pay who know how much for something that I do not know what's wrong.. If you have any ideas please let me know.. Thanks!!

By the way, how do you go around it when recording?? I tried recording a track and that electrical noise comes out in the recording too.. It's just annoying!!

this is a ground issue. THe radio station comes from a cable that handles current touching a poorly shielded cable for audio, thus turning the audio cable into a big long antenna, kinda like those kits you could buy at radio shack to make your own radios. The longer the cable the more you pick up. Remember them things from off of TV you can plug into your power outlet to "turn your whole house into a TV antenna"? this is the same principle.


If the power cord touching it were grounded correctly this would not happen, unwind the cables and use twistties to keep them from touching and the problem will go away, also invest in better shielded cables, I find that moster makes some nice ones.

also, HOSA does make some messed up cables, I had a lot of problems with them until I switched to monster. I think its just that moster is much more consistent in thier manufactuing oversight then other compaines are.

I am even more confused now.. I unplugged the outputs and plugged in some headphones and I do not get the electrical noise through my headphones... I know for sure that my VS-1680(Mixer is nto the problem because I have other devices connected and I'm only getting the hum from the MPC.. Ahh!! I dunno what's going on.. Do you guys that the MPC outputs might be messed up? I'll keep fighting with this until I'll get it fixed.. Hopefully you guys give me your support and continue to add your 2 cents.. Thank you again for all of your help.. Keep suggesting, I'm all ears right now!!

SEEING THAT YOU'VE GONE THRU AND DONE A SYSTEM CHECK I'M ALMOST CERTAIN IT'S THE CABLES. AND JUST AS DR. FOO STATED MONSTER CABLES ARE THE ISH!! ONLY THEY COST LIKE 20 BUCKS A CORD. AND THEY ARE WELL WORTH THE INVESTMENT. AFTER NARROWING THINGS DOWN TO THE CONNECTION IT APPEARS TO BE YOUR PROBLEM. BUT BEFORE YOU APPLY THIS ADVICE MAKE SURE YOUR CABLES AREN'T CROSSING OVER POWER CORDS THAT ALSO CAUSES THE SAME RESULTS FROM TIME TO TIME. AIGHT, GOOD LUCK HOPE YOUR BACK IN BUISNESS!

yes,
cabling is almost certainly the issue. sounds like you have a bad connection in the cable or your cables are not shielded very well. invest in a pair of good cables. even if it turns out that that is not the problem, you will end up using those cables somewhere down the line anyway. but i am pretty sure it is the cables.
