ART Pro MPA-II Two Channel Mic Preamp

The ART Pro MPA-II is an affordable dual channel tube microphone pre-amp with VU meters. The Pro MPA-II will surprise you. At this price-point, the Pro MPA-II rivals many other tube preamps that cost a lot more. Key features on the MPA-II are variable input impedance, dual mono or stereo operation, M/S stereo miking support, dual gain stage, instrument inputs on the front and a low cut filter per channel. Check out some user reviews from Gearslutz and SOS.
