AED1,299.00

TheĀ Atlas Sound TSD-ML11 1×1 Mic/Line Preamp with EQ and MuteĀ is a high headroom, low noise mic preamp that can be used as a standalone preamp or in conference room systems, board meetings, courtrooms, council chambers, and public forums system that need mute and push to talk microphone functions.

The TSD-ML11 features switchable phantom power for powering condenser microphones and has four EQ cut filters centered at common frequencies to eliminate feedback and control voice shaping. 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.

An output limiter/compressor is also included for system protection to avoid clipping and eliminate distortion. Mic Mute and Mic On control allows microphones in the system to be push-to-talk enabled or muted for speaker priority. The unit requires a power supply (not included) for operation.
