Sound Devices MM-1

Borrowing the same award-winning microphone preamplifiers found on their 744T digital portable interface, the Sound Devices USBPre 2 provides one of the highest quality portable interfaces available for both Mac and Windows computers. The USBPre 2 is equipped with a pair of fully discrete, transistor-based XLR inputs and impressively lucid 24-bit converters that are capable of up to 192kHz sample rates.

Additional inputs for line-level sources and consumer audio electronics, as well as S/PDIF optical Toslink digital devices are also available. A 23-segment, multicolor LED meter provides you with the essential feedback you need to keep an eye on your levels, and are an invaluable asset when using the USBPre 2 as a standalone preamp and A-to-D converter.
The MM-1 is at home in high-definition television production, corporate/industrial environments, radio/television announce booths, and music production.

Its headphone monitor 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.

Sound Devices’ MM-1 is a single-channel, portable microphone preamplifier with a powerful headphone monitoring function. Proven in mission-critical applications, the high-performance microphone preamplifier uses 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
