Product Description
The Tube Tech MP 1A is a combined dual Microphone Preamplifier and Direct Instrument amplifier for microphones or instruments.The microphone inputs and outputs are balanced as well as fully floating. The inputs provide a switchable +48 V phantom power as well as a switchable -20 dB pad. Gain is adjustable in 5 dB increments from +20 dB to +70 dB.
The Direct Instrument Inputs are unbalanced with a gain ranging from + 10 dB to + 60 dB.
The amplifiers are all tube based and the heaters are on a strict diet of DC-voltage only to avoid hum. All transformers, with the exception of the mains transformer, are enclosed in MU-metal cans. Input and output transformers come with a static screen between the primary and secondary windings.
