ART Pro MPA-II Two Channel Mic Preamp

Yes, the unit features selectable stereo or dual mono operation. This makes it equally effective for stereo miking techniques like X/Y or Mid/Side, or for tracking two completely different instruments or microphones simultaneously.

Variable input impedance allows you to change how the preamp 'loads' your microphone, which subtly alters the frequency response and overall character of the sound. It is a great tool for fine-tuning the tone of ribbon or dynamic microphones to get the best performance out of them.

With a maximum gain of 75dB, the MPA-II provides plenty of clean headroom for most low-output ribbon or dynamic microphones. You should be able to achieve a healthy signal level without needing to push the preamp into noisy territory.

The selectable plate voltage lets you choose between a 'normal' setting for a more transparent, high-fidelity sound, or a 'high' voltage setting that introduces more tube warmth and harmonic saturation. It essentially gives you two different sonic flavors in one box.

Yes, the MPA-II includes a front-mounted instrument input jack. This allows you to use the unit as a high-quality DI box, letting you capture the character of your instrument's pickups through the tube circuitry before hitting your interface.

The high pass filter is fully adjustable, allowing you to sweep the frequency between 10Hz and 200Hz. This is very useful for cleaning up low-end rumble or mud from your recordings during the tracking stage.
