The MMC 1A is our latest recording channel encompassing a complete front-end it includes an additional Direct Instrument input as well as a separate line input. The microphone input has switchable loading impedance, phantom power, phase reversal and a 20 dB Pad. All inputs are equipped with a low-cut filter. The 3-band optical compressor is designed to maintain optimum summing of all three bands with a remarkably flat frequency response. A bypass switch shorts out the whole compressor. Mic. Input/Output are balanced and have fully floating transformers with a static screen. The Line Input is unbalanced, but an optional transformer is available. The power supply and the sidechain circuits are based on a solid state circuit. With the exception of the output stage all DC voltages are stabilised. Product Features Mic.
