I did so because I felt like akai where holding information back on this subject, while acting as if they like to have you involved in some development community. Which is ofcourse marketing strategy.

Anyway, the akai dude on youtube literally said they copied the exact 3000 circuit from the dacs to the jacks. So I went through the 3000 service manual to look up this piece of circuit, and found just what I thought.

The only thing thats in between the dacs and the jacks of a 3000 is an anti aliasing filter. Basically a two pole low pass filter without any resonance, and with its -3dB point at 26 KHz.

Nothing special, nothing to add any coloration. Just a lowpass filter outside of the audio region.

Dont believe the hype. Ever.

Yup. It was pretty clear from the beginning it was marketing BS.

So that is only half the picture then.

No, the Ren just has a typical 24bit/96khz AD/DA converters you find everywhere else.

That schematic you posted doesn't show an DAC or output jacks just some OP amps with associated components with feedback resistors and filter capacitors, this doesn't show the DAC or output so how are we to know how they are connected to it.

So what is that schematic actually showing?

It looks like a circuit made in Multisim rather than copied out of a service manual.

Sorry this is just coming from someone who wants a clearer explanation, I've spent a lot of time studying audio schematics while repairing music equipment as my job so thats all... I don't see anything here proving what you say (I'm not saying you are wrong but this could be completely random) and why should I believe you any more than I should believe AKAI?

Thats all..... no offense intended, glad you've look into it :smoker:

i seriously concur.


these marketing conspirators seem to think everyone is a foolish noob...

im a fool, and a noob, but even i aint that gullible... :oops: 8) :P


"vintage mode"...


PAY THE FUKN MAN ALREADY!!!!!!!!! :fku:

This discovery makes me reflect on the early Youtube videos that AKAI released announcing the new MPC-line (REN/STUDIO/FLY). These videos profiled well-respected producers as bouncing buffoons happy about making beats on the new MPCs.

Perhaps AKAI thought that their target audience for the REN/STUDIO/FLY would be easy to fool with simple marketing ploys. Just a thought, my friends.

What does that anti-aliasing...two pole low pass filter without resonance do exactly?

Have you done a hands-on comparison of the MPC 3000 and the MPC Ren sound?

Look up "Nyquist frequency". it's basically just a filter put where aliaising will occur on the incoming audio. It made more sense to me when I read about how it works on images...

No **** Sherlock, that's the software vintage mode..... :-D
