The Sound Devices’ MM-1 portable microphone preamp/headphone monitor is single-channel and can be used to monitor sound for film (boom operators), broadcast, ENG, voice-over work and corporate/industrial environments.
The mic preamp has exceptional audio quality with a dynamic range exceeding 120 dB, an audio bandwidth of 10 Hz to 50 kHz, and user-switchable 12V, +48V, and 12V-T phantom powers. An additional balanced monitor input can accept either a balanced or unbalanced signal.
The 1/4″ TRS output can be used to monitor microphone signal or external line-level signal, or both.
The 3-position low-cut filter switches eliminate noise below 80 Hz or 160 Hz. This compact unit is equipped with a belt clip, 2 AA batteries, or an external DC power source.
