ANALOGUE SAMPLING ISSUE

HELLO PLEASE HELP!!!

I'M TRYING TO SAMPLE SOME VINYL STRAIGHT INTO MY NEW MPC 2500 SE USING RCA TO 1/4 INCH ADAPTER PLUGS BUT AM HAVING A FEW ISSUES.
I'VE SUSSED OUT SAMPLING IN DIGITAL FORMAT WITH MY CD PLAYER AND AM HAVING NO PROBLEMS WITH THAT BUT WHEN TRYING TO SAMPLE AUDIO IN ANALOGUE FROM MY TECHNICS 1210 UNIT, I CANNOT RAISE MY LEVEL METER BARS ENOUGH TO WARRANT RECORDING. I CAN TURN LEVELS RIGHT UP BUT NOT WITHOUT SEVERE RESONANCE (HUMMING SOUND) I'VE MADE SURE MY REC GAIN IS UP, ALONG WITH SUFFICIENT VOLUME AND AM IN STEREO MODE WITH THRESHOLD REDUCED TO ZERO BUT STILL NO JOY. OH BY THE WAY THERE ARE NO FOREIGN CABLES INTERFERING WITH THE AUDIO CABLES.

ANY IDEAS GUYS???

absolutely.. I got a good idea I am 90% sure is causing the issue..

you dont have a phono preamp, you are running the record player right directly in to the mpc..

I will mention a few options to fix it if you get rid of the caps lock.

you need a phono preamp.

sometimes you can find one built into an old receiver that has a turntable input, or you can just buy a standalone one.

phono preamp.

ok caps lock gone lol!!!

do most use a preamp when sampling from vinyl?

forgot to mention that i've run through my quad 306 amplifier with no significant improvement.

yeah man, you can get a cheap DJ mixer with phono inputs (most have those, all that were designed to use record players) the korg kaoss pad 2 has one built in.. this is nice because at the same time you can use the effects and filters to change the sound, also you can get a cheapo one for like 20-30 bucks that is a standalone unit.. i think behringer makes a cheap budget phono preamp.

the mpc has its own mixer so why will i have to do this? shouldn't it manage the audio it's self?

will an external mixer have a preamp of sorts in it then?

as much as i love this thing they really have cut all costs at the manufacturing stage haven't they?

my metronome appears to have stopped working now as well with all settings correct it just makes a muffled sound instead of clicking. it worked before!!! any ideas?

oh and also what would be the largest size ide drive to install into my 2500 or is there no limit?

yeah it has an internal mixer for controlling the levels and panning of the internal sounds etc...

the DJ mixer is not for doing any of that... it is simply to use it's PHONO input.

here is the problem, while record players such as the 1200/1210 ... it has the RCA output cables right? but they dont give out a line level signal (which is needed for the line input of your mpc) .. it gives out a PHONO level signal... which contains less amplification than the line level signal. Therefore, a device like a phono preamp, a dj mixer that contains a phono input, or a device like I mentioned such as the korg kaoss pad 2 has that component built in...

some samplers come with a phono preamp (phono input) (such as the mpc5000 and the roland mv8000/mv8800) which is an added bonus on those machines but hardly needed to get the job done since you could always do as I suggested above..

now again, the dj mixer (not a regular mixer, but I am talking specifically about DJ mixers here) is not to adjust the levels and panning of the finished song... it is simply used as a sort of converter for the record player to the mpc.

Much more important than the amplification IMO is the correction of the frequency curve.
A phono preamp include the amplification AND an EQ with a fixed and standardized curve called the RIAA curve. This is because of the physical specification of a vinyl recording. It's not possible to simply press a vinyl with the actual signal that comes from the master. Therefore the signal runs thru an EQ (with the inverted EQ curve of phono preamps) before pressing.

im wondering: does this twice EQ-ing have any effects on the phase of the cut and boosted frequencies?

Right - a phono pre-amp is not just for boosting the overall level!

http://en.wikipedia.org/wiki/RIAA_equalization

Without the RIAA EQ in a phono pre-amp the record will sound wrong, it won't just be too quiet

AntonPD: I don't think so, but if there is a phase change it will affect every frequency, the adjustment is a curve, not just a high-pass filter and low-pass filter to cut/boost the highs and lows.

And earth that turntable to, there should be a wire hanging out the back that needs to be attach to the pre-amp. That will stop one source of hum and noise.
