Designed for high-definition field production applications, the Sound Devices MP-1 is a single channel microphone preamp that delivers studio grade audio in a portable, lightweight package. The unit features a transformer balanced XLR microphone input and line level output resulting in high gain and low noise floor. A large gain adjustment dial provides up to 66 dB of gain in eleven discrete steps.

A 3-position phantom power switch enables 12V or 48V phantom power for condenser microphones. A low-cut filter switch eliminates noise due to wind and proximity effect at 80 Hz or 160 Hz (user switchable). Peak limiter switch moderates signal peaks, eliminating distortion due to signal over load. The MP-1 is powered with 2 AA batteries for approximately 24 hours.

Body of unit is covered in black tape to prevent damage to finish.
