Get to know them!

A Designs MP-2A Dual-channel tube mic pre — A Designs has recently emerged in the forefront of insider audio to rave reviews; "Stunning sound quality with serious bass response and a warm, airy top," "Adding the MP-2 to my Direct-to-Disk DAW was like finding the holy grail of warm analog sound. I use it on everything from bass to guitars to vocals to drum mics and more. Absolutely incredible." The A Designs MP-2A is an Input and Output transformer, classic tube preamp with tone switches that give you four unique preamp colors. For use with the modern crop of ribbon mics, the A Designs MP-2A provides 60dB gain along with a 48V phantom power switch, phase switch, a big VU meter, 20dB Pad, and a hi-Z DI instrument input. Bring the warmth and richness of analog to your recordings with A Designs MP-2A.

High-end tube, 2-channel preamp

The original MP-2 tube preamps have been a favorite of LA insiders for some time. Comparable to much more expensive tube preamps, A Designs now takes it a step further with the MP2"A" Series, adding tone switches to the same great sound they have become known for. It is now possible to get four distinct "world class" sounds from a single unit! This makes a single preamp much more useful in the studio and over time.

True Tube

The A-Designs Audio MP-2A is considered a "True Tube" preamplifier due to the fact that there are no ICs (Integrated Circuits), transistors, or and solid state design in the front-end or the back-end to color the audio signal path. The sonic signature of the MP-2A is composed of pure tubes, film capacitors and custom transformers, pure and simple. Handcrafted with point to point wiring the MP-2A a must for those that care about quality.

Custom-wound transformers

Its surprising how few pro companies believe in transformers they way A Designs does. Transformers are the heart and soul of any preamp and greatly affect the sound. Careful attention is devoted to designing the transformer and its parts: changes in core material alloy yields different sounds; the windings, what wire, how many turns and how they are wrapped all affect the sound too. A Designs spends a lot of time to design a high end transformer that adds beauty to the sound. These special transformers are one of the key reasons the A Designs reputation has grown so rapidly.

Direct Instrument Inputs

One unique features of the MP-2A is the 1/4" "Direct In" for high-impedance instruments and sources. Unlike most companies, A Design Audio's direct input goes straight to the transformer for glorious tone! Vintage Guitars, basses, digital keyboards — everything including drum machines benefits from the unique character of the A Designs hi-Z input. This provides your with a valuable option of using the on board DI instead of purchasing an expensive tube/transformer based "Direct Box". If you are looking for that "Analog Tube Sound" for your instrument, the MP2A is ideal!

  • Dual channel XLR line inputs
  • Dual 1/4-inch hi-Z "direct to the transformer" inputs
  • Continuously variable gain control
  • 60dB Gain
