Sound Devices MP-1
Portable Microphone Preamp
Portable, single channel, battery powered microphone preamplifier with 20 Hz – 50 kHz bandwidth and >120 dB dynamic range. Features include 48-volt and 12-volt phantom power, high pass filter, limiter, transformer-balanced input and output. Powered by 2 AA batteries.

Key Features
Superb audio specifications 66 dB of gain, in eleven discrete steps Transformer-balanced input and output Phantom power - 48 volt or 12 volt High pass filter @ 80 Hz or 160 Hz, 6 dB/octave	Limiter makes unit virtually "unclippable" High current line output drive Excellent immunity to RF interference Battery power (two x AA) Durable mechanical construction
