Nasty hum

I have a whole day to play with my mpc. I 've been sampling some records, but i keep getting a nasty hum or buzz. Do i just need to ground the turntable to the mixer or just get one of those black boxes that will take the buzz out or both?

If you haven't grounded your turntable DEFINITLY DO THAT! You shoulda did that first. Also move your equipment away from each other. Especially your monitors and your turntable. You'll get alot feedback if your turntable is sitting right next to your speaker.

ive always had my turntable right next to my monitors and i get no hum?..

so i don't need one of the boxes that blocks the hum for 50 bucks?

your monitors might already be shielded and/or your turntables might already be grounded..

sometimes it's just the vibration from the monitors that cause feedback..

Thats funny. If I put mine within a couple inches of each I a whole bunch of hum.

Grounding the mixer to the turntable did the trick, thanks to all

I have the same prob. I have it grounded on the turntable because i dont have a grounding nut on my mixer (its not a dj mixer just a soundcraft compact 10 with riaa equalizers) is there any cheap solution to this prob, i would perfare not to but a dj mixer. Sorry for jacking the thread btw.

also, when sampling IN to the MPC, turn your volume control down as low as possible, just enough so that you can still hear what you're doing...

to stop vibrations from the speakers?

You said you have the turntable grounded to itself. That mod usually works so I’m not sure whats wrong...

no, because it just creates extra white unnecessary noise....turn your speakers on your monitors up, go in your sampling screen and then turn up and down your volume knob...when it is up all the way, you will notice the extra noise...

Oh okay, yeah I know what you mean. You’re talking about the Gain control on the MPC, not the Master volume. A better way (I think) of saying that is to keep the Gain on the MPC as low as possible at all times. And when necessary, increase the signal strength as close as possible to the source. ‘Cause when you sample from your mixer, you’re already getting some unwanted noise (in my experience it’s usually not too noticeable though), so if you make sure the signal going into the MPC is hot enough to start with, you won’t have to use the Gain on the MPC… Because by doing so, you are also increasing the volume of the white noise from the mixer etc. …Same thing with increasing the level of a sample from the TRIM -> PARAMS screen post sampling.

I'm talking about master volume.....

So you must be talking about the Master out on the mixer/sample source?
