The Tube-Tech MP 1A Microphone Preamplifier is a combined dual microphone preamplifier and DI amplifier for microphones or instruments. The microphone inputs and outputs are balanced as well as fully floating. The inputs provide a switchable +48V phantom power as well as a switchable -20dB pad. Gain is adjustable in 5dB increments from +20dB to +70dB.

The Direct Instrument Inputs on the MP 1A are unbalanced with a gain ranging from + 10dB to + 60dB.
