Description
Tube microphone preamp, 2 channels.
The ART PRO MPA-II is a two-channel tube preamp. The PRO MPA-II input section is equipped with 2 12AX7 lamps which operate at low or high voltage, selectable by channel, for wider variations in tone and preamp performance.
The PRO MPA II has 48V phantom power per channel, and also offers a variable input impedance level, which radically changes the sensitivity and performance of any dynamic or static microphone used.
The PRO MPAII can be configured for dual mono or stereo operation with a selectable mid / side microphone support, allowing summation of left / right signals.
Large backlit VU meters display analog output levels while multicolored LED levels show tube gain and output levels.
The PRO MPA 2 is equipped for each channel, XLR and Jack TRS inputs and outputs, and has an instrument input (High Z) on the front.
