The Sound Devices MM-1 is a single channel, portable microphone preamp and headphone monitor designed for monitoring sound for film (boom operators), broadcast and ENG, field recording, voice over and corporate / industrial environments. The mic preamp features exceptional audio quality with a dynamic range exceeding 120dB and an audio bandwidth of 10Hz to 50kHz. The balanced XLR microphone input provides user switchable +48V, 12V and 12V-T phantom power. A separate balanced monitor input accepts balanced or unbalanced line level signal. The 1/4″ TRS headphone output is capable of monitoring microphone signal, external line level signal or a mix of both. A 3-position low cut filter switch eliminates noise below 80Hz and 160Hz. The compact unit features a belt clip and is powered with 2 AA batteries or external DC power source.
