TSD-ML111 x 1 Mic/Line Preamp by Atlas Sound is a low noise mic preamp is perfect for use as a standalone preamp or in conference room systems, board meetings, courtrooms, council chambers, and public forum systems that need mute and push to talk microphone functions.
It has a switchable phantom power for powering condenser microphones and has four EQ cut filters centered at common frequencies to eliminate feedback and control voice shaping. An output limiter/compressor is also included for system protection to avoid clipping and eliminate distortion. What's even better is that it has a Mic Mute and Mic On control allows microphones in the system to be push-to-talk enabled or muted for speaker priority.
The variable mic preamp helps further eliminate noise for quiet operation as well as reduces unwanted coloration and changes in tonality and a 12dB @ 125Hz high pass filter is available on each mic input to minimize bass rumble and low frequency feedback in the system and ensure focus and clarity stays on voice sound spectrum.
