A Designs MP-2A

There aren’t many preamps that engineers and producers feel could be the only one they would use to make an entire  record; but, according to industry professionals, the all-tube MP-2A stereo preamplifier fits that bill. Designed to provide the  versatility and sonic flexibility sought after by discerning professionals around the world, the MP-2A “works and plays well  with others” - meaning that while some preamps can be finicky when it comes to certain mics, the MP-2A performs  spectacularly no matter what kind of mic you run through it: ribbon, dynamic, or condenser….old school, middle of the road,  or state of the art – MP-2A welcomes them all…but it doesn’t stop there!  MP-2A is also an excellent instrument pre/DI,  adding life and depth to basses, guitars, analog and digital keyboards. 

Built to audiophile-quality standards with a price tag well below other boutique preamps in or near its class, the MP-2A has  no integrated circuits in the signal path - it relies solely on discrete components: the perfect combination of tubes (EF86 for  the inputs, 6N1-P on the outputs), Audience capacitors, and custom Cinemag Output transformers, and is meticulously hand  crafted with point to point wiring. Each channel sports a -20dB pad, a pair of Tone switches providing four distinctive possible  sonic signatures on each channel, and up to 60dB gain for use with even the most power-hungry ribbon mics.  Cinemag  input transformers coupled with custom-wound output transformers ensure the low noise top-quality performance expected  from a top shelf preamp. Additional features include balanced Neutrik XLR inputs, true VU metering, 48v phantom power,  polarity switches, and front-panel Hi-Z input jacks.
