The Tube-Tech MP2A is an all tube two channel microphone & Instrument pre-amplifier, with variable impedance settings to accommodate a range of microphones and input sources.
The TUBE-TECH MP2A is a combined Microphone Preamplifier and Direct Instrument amplifier. The input provides switchable +48 V phantom power, selectable mic. impedance of 600/1200/2400 Ohm, phase reverse switch, low-cut filter (20 Hz/40 Hz/off), as well as a switchable -20 dB pad. Gain is adjustable from +10 dB to +70 dB.( 10db steps, coarse +2 dB steps, fine.) The Direct Instrument Input are unbalanced with a gain ranging from + 10 dB to + 60 dB. The amplifier is all tube. Input transformer is enclosed in a MU-metal can. Input and output transformers come with a static screen between the primary and secondary wirings. The input and output are balanced as well as fully floating.
