Hi everybody! I'm new to the forum and the MPC itself and I could use some help. Sorry for bad english, I hope it's readable.
What I have is an MPC 1000 with JJOS2XL 3.57 and 128MB. I bought it a while ago and so far I'm loving it.
To the problem. When sampling in stereo, it's all good. Everything is as should be. But when sampling in mono, regardless how high or low the rec gain, there is a lot of cracling and popping. It sounds as I was tuning an old radio when listening to the sound. It doesn't matter whether mono L, mono R or mono L+R, the problem is still there.
I have tried sampling from a cell phones 3.5mm socket using:
3.5mm TRS to 2x RCA cable, with two RCA to 6.35mm TS adapters. Listening with headphones using a 3.5mm to 6.35mm TRS adapter.
I have also tried sampling from vinyl in the following way with my cheapo vinyl listening equipment:
Non-removable 2x RCA cable from turntable (Dual CS-503-2) to an integrated amplifiers (Akai AM-U55) phono sockets, earth wire in place of course. 2x RCA to 2x RCA from amplifier to MPCs record in socket with two RCA to 6.35mm TS adapters. Again listening with headphones using a 3.5mm to 6.35mm TRS adaptor.
Source of sampling does not seem to affect the problem in any way. Also, if this is of any help, I did some maintenance on the machine. I swapped all the tact switches, a few leds, button kit, pads, knobs etc. I also cleaned inside and out. The problem was there before the operation and it still persists.
I've been searching online for info for the past week or so. I couldn't get any answers from either the MPCs quick start manual or the user manual. Also searched from this forum quite a bit. I found this other thread here which seems to discuss pretty much the same issue but problem was with stereo, so the other way round. RAM seemed to be faulty there. Do you think this could be the case with mine?
If someone has any tips what am I doing wrong or what might cause this problem, your help is greatly appreciated. Thanks in advance!
