Audio Technologies Inc. M100-ATI
Microphone Preamp with Limiter, Low Cut, and Phase Reverse

M100-ATI

Eliminate noise, pickup, RF, hum and rolloffs from long low level microphone cables with the ULTIMIKE Microphone Amplifier. Ruggedly designed for up close operation, impressive input headroom specs and smooth output limiting allow trouble-free unattended operation from remote or inaccessible locations. A unique distortion-free transformer coupled output provides total isolation of ground loops and ground voltage differentials with a low line driving impedance for extended high frequency response when driving long lines.

The direct, instrumentation amplifier input stage yields superior noise performance and prevents the ringing, response and distortion problems of high ratio input transformers. High gain for low output microphones is combined with excellent input and headroom for complete freedom from overload. The maximum input level of 0dBu is increased to +20dBu in the low gain switch position. A screwdriver adjust audio taper full range gain control can be augmented with a convenient plug-in remote DC operated gain trimmer located up to 50 feet away. Other outstanding features include a clean output limiter, full 48 VDC phantom power, a two pole 150Hz low cut filter and switchable output phasing.
