AKAI MPC X Mod

We are offering the following modification for the MPC X:

XB Mod

Analog

• – New high-grade op-amps on the line inputs, mic inputs, line outputs, main outputs, and headphone outputs (this improves INST 1, INST 2, and the phono/line RCA inputs as well)
• – New, high-grade signal path capacitors on the line inputs, mic inputs, line outputs, main outputs, and headphone outputs (this improves INST 1, INST 2, and the phono/line RCA inputs as well)
• – Upgraded global and local power decoupling on analog stage power rails
• – Improving the performance of the analog stage circuits makes a drastic difference for tracking and mixing (expect amazing micro-dynamics and space)!

Digital

• – New internal, ultra-low-jitter, XB word clock with proprietary implementation
• – Proprietary decoupling on all A/D and D/A converters using methods found in our Signature, FM, and XB modifications
• – Our approach to converter decoupling reduces noise generated during the conversion process, leaving you with crisp, clear audio!

Hear audio demos of the before-and-after on the MPC-X SE’s inputs and outputs below!

If you would rather not use SoundCloud, you can download .WAV files of the modded and stock recordings here.

The production and recording process:

We felt it important to demonstrate the tonal character of both the D/A and A/D conversion on both stock and modded units, so we used a recording process that involved looping back the MPC’s own outputs back to its inputs.

On both stock and modded units, the tracks were composed in the MPC X SE and routed from Line outputs 3 and 4, and back in to the Line inputs 3 and 4, recorded at 44.1 kHz and normalized. This way, the characteristics of both the D/A and A/D converters are all present in the recordings, and the files are time-aligned for null testing.

Listening tips:

Critical listening is a learned skill. We recommend zeroing in on a particular instrument when comparing files. Evaluate each instrument’s tone, texture and transient response. Then, when consuming the tracks as a whole, pay attention to what happens to the space (or lack thereof) in the mix when things get busy. Always listen on the highest quality playback system available to you – not in your car or on your phone.

Start at the high end and work the way down. Listen to one instrument at a time, starting with cymbals and hats, then focus on the mids and the vocals, followed lastly by the bass elements. Listen for texture.

Enjoy!
