A-Designs MP-2A Stereo Tube Microphone Preamp

A-Designs MP-2A Stereo Tube Microphone Preamp



The A-Designs MP-2A Stereo Tube Microphone Preamp not only offers two tone switches per channel (four distinct sounds), custom transformers, plus polarity (phase) switches in order to treat any sound source as desired.

While some preamps can be awkward when it comes to certain mics, the MP-2A welcomes all and sounds great no matter what you put through it; ribbon, dynamic, or condenser. Whether you’re looking for clarity and transparency, or the rich, euphonic sound of input tubes driven hard, the MP-2A can give you all that and more.

Each channel features a -20dB pad; two selectable tone switches for four possible tones on each channel; 60db gain for use with next-generation ribbon mics; and Cinemag input transformers coupled with custom-wound output transformers, delivering the low noise and top-quality sound you demand from a high-end preamp. Additional features include balanced combo XLR/1/4″ inputs, true VU meters, phantom power, polarity switches, and front-panel, line-level input jacks.

Built to audiophile-quality standards, the MP-2A has no integrated circuits in the signal path – it relies solely on discrete components, namely tubes, film capacitors, and custom transformers. To maintain the integrity and purity of its sonic signature, bells and whistles are kept to a minimum. This serves two purposes: First, the more switches in the circuit path, the more sound quality can be negatively affected. Second, by keeping only necessary features, costs are kept down and your money goes where it really counts: sound quality.

Thanks to its fixed-gain amplifier with output attenuator, you get consistent behaviour (the magic) whether the MP2-A is turned up or down. It also provides polarity switches, which allow you to record a stereo sound source out of phase in order to enhance stereo imaging, or tame overwhelming bass via cancellation. Factor in the tone switches that give you a palette of four unique sonic flavours on each channel, and you can easily see why we say you could make an entire record with just this one versatile preamp.

The main features of the A-Designs MP-2A Stereo Tube Microphone Preamp include:

  • Dual tone switches for creating distinct and varied sounds
  • Plays nicely with all designs of microphone
  • All discrete circuitry
  • Fixed gain amplifier for consistent behavioural characteristics
