Sound Devices MP-1
Portable Microphone Preamp

MP-1

The MP-1 is a portable, battery-powered microphone preamplifier with phantom power. Designed for high-definition field production environments, the full-featured studio-quality MP-1 is an ideal line-driver for critical radio, television, and film applications.

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.

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
