Technical questions for the MPC2000xl and the MPC2000

When I open up the sample window I notice a very slight hum that progressively gets louder as I turn the gain control up. Now, I can still sample and get a good quality sound but just the fact that I hear this slight hum bothers me because it is not 100% clean sound. Also, this happens when there is nothing plugged into the line in. I did a search and got mixed answers so I'd like to clear it up within my own post.

So my question is, when you guys are in sample mode, is it completely silent or is that slight barely noticeable hum inevitable?

Tried this, same result. Someone in a post wrote that you're always going to get a little noise when sampling on an MP. The noise I get is more like white noise. It is very noticeable when I turn the gain all the way up. I don't sample with the gain all the way up though. I'm just trying to get my samples extra clean. But I feel like I have to live with what I got. For all I know this shit could be normal and I could be trippin.

you shoulnt need to turn the gain up at all, try using a preamp.

please provide details. We can not offer any valuable answers without valuable details.

What are you sampling? what hardware do you have and how do you have it hooked up?

What about your other Equipment? What are you using for sampling into the MPC.
For a high signal to noise, always gain your stuff from the source first (for example, channel gain/trim on the DJ Mixer for the turntable till it peaks to 0dB or +3dB, then turn up the DJ Mixers Main to ca 80 percent and if it goes straight to the MPC it should be loud enough to gain the MPC at ca 10:00 and get loud results with no noise.

Where do you connect your MPC for playback??

I told you all that this happens without anything in the inputs. It's not noisy just something only someone anal about their sound could notice. I got that OCD.

I get clean samples when I record.

I just wanted to know, if it was normal to hear white noise if the gain is all the way up. Of course I'm not going to record with the gain all the way up. I don't even need to. I was just testing my shit.

I would just appreciate it if any of you ran a quick test for me by turning your 2000xl, go to sample mode and turn your gain all the way up and tell me what you hear without anything being inputed.

Volume and Gain all up = noise
When I turn down the Rec Gain just a little bit ( ca 2 mm ) the noise abrupt gets relaive quiet.
Oh and I had my Master Output (in the Setup Menu) at 0dB and not at 12.

this is not normal. you should not have any hum with the inputs not conected. it could be a ground issue. it could be that at some point a power spike hit your unit and did minor damage to the input stage of your mpc. and just because it did the same thing in a different plug in your house doesnt mean thats been completely ruled out. alot of plugs are on a single leg in the circuit panel. try it at a homies house too. just to be sure. if its your house woring then you need a power conditioner.

i will usually get a slight buzz or hiss if the rec gain is turned up too high. its normal far as i know.

you should have the device your getting your sample from turned up to max volume or close to, so you dont need to turn up your gain to the point the hiss becomes noticeable.

Mine does a "similiar" thing. However I only hear it with the REC gain at nearly full. And the output gain past 3 o'clock.

To me it sounds like the signal floor, we are dealing with analog cables that have a higher signal to noise ratio than digital.


As long as the noise isn't overbearing, it should be fine.
