Sound Devices MM-1 Portable Microphone Pre Amp Overview: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.Highly Versatile and PortableSound 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 or 12 volts and 12-volt T-power. It is powered from two-AA batteries or external 5-17 VDC, such as via the PIX-E PSU.Features:
- Maximum of 66 dB of gain, in eleven discrete steps
- Dynamic range exceeding 120 dB
- 10 Hz to 50 kHz audio bandwidth
- High immunity to RF interference
- High current line output driver
- Transformer-balanced input and output
- Extended range peak limiter via dual opto-isolators makes preamplifier virtually “unclippable”
- Selectable 48-volt / 12-volt phantom power or 12-volt “T” power
- High-pass filter @ 80 or 160 Hz, 6 dB per octave
- Headphone monitoring of microphone audio, monitor audio, or a mix of both
- Monitor input accepts mono, balanced or unbalanced line-level inputs on 1/4-inch tip-ring-sleeve connector
- Separate level control of Monitor gain and overall headphone gain
- Split ear function via DIP switches
- Internal battery power (two-AA)
- Excellent battery life with alkaline and NiMH rechargeable batteries
- External 5-17 VDC powering
- High-strength aluminum chassis with durable belt clip
