The M100 from ATI Audio is single channel microphone preamp, designed for trouble-free unattended operation from remote or inaccessible locations. Ruggedly designed, the unit eliminates noise, pickup, RF, hum and roll-offs from long, low level microphone cables.
A distortion-free, transformer-coupled output provides total isolation of ground loops and ground voltage differentials, while a low, line-driving impedance helps maintain extended high frequency response when driving long lines.
The amplifier input stage yields superior noise performance and prevents the ringing, response and distortion problems of high ratio input transformers. Additionally the unit includes a clean output limiter, full 48VDC phantom power, a two pole 150Hz low cut filter and switchable output phasing.
