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 12 or 48V phantom power for condenser microphones. A low-cut filter switch eliminates noise due to wind and proximity effect at 80 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 (available separately) for approximately 24 hours.
