Sound Devices Mm-1 Microphone Preamp

Highly versatile and portable, The Sound Devices MM-1 is a Single-Channel Portable Microphone Preamplifier with a powerful headphone monitoring function.

The MM-1uses a transformer-balanced input and output with a bipolar 15 volt power supply to produce low-noise, low- distortion gain at all switch positions. It features an "unclippable" dual-stage limiter and two-position high- pass filter.

Flexible microphone powering provides phantom power at 48 volts or 12 volts and 12-volt T-power. It is powered from two-AA batteries or external 5-18 VDC.

The MM-1 is at home in high-definition television production, corporate/industrial environments, radio/ television announce booths, and music production.

Headphone monitoring is an advantage in applications where communications channels or mix-minus feeds need to be monitored in headphones. The user can monitor both microphone audio and external audio sources in headphones with level control.

The MM-1 is designed to be durable. Its aluminum chassis, oversized end panels, machined knobs, and panel mounted connectors assure reliable mechanical operation.
