Sound Devices MP-1

The MP-1 is extremely durable and easy to use. With rugged mechanical and electrical construction and high-quality components, it will provide years of superb audio performance under the most punishing field conditions.

• 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
