The ART Pro MPA II is a dual-channel tube mic pre with a range of useful features for the home recordist or project studio on a budget. Continuously variable impedance and a whopping 70dB of gain on tap make the Pro MPA II a perfect pairing for all types of microphones, while an onboard mid-side matrix unlocks M/S stereo recording. Switch between normal and high plate voltages to change up the tone and suit whatever source you're recording, filter out any low end rumble with the sweepable high-pass filter, or plug your bass or keys straight into the direct input to give your instruments a life injection. This versatile, affordable preamp makes for an awesome upgrade to the built-in pres on your interface.
