Following the path of success shown by our much-acclaimed TUBE-TECH SMC 2B Stereo Multiband Compressor, we are proud to introduce our latest technological achievement: A full-blown microphone preamplifier & multiband compressor with outstanding sonic properties – the MMC-1A.
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 stabilized.
The MMC1A makes wonders in recording or mixing difficult sources like very dynamic voices or instruments where the tonal character changes with level.
MMC1A can deliver "automated" control where it normally takes loads of work to achieve perfect results. Many singers have been "saved" by the MMC1A.
MMC1A also opens up new exiting creative possibilities in recording and mixing full range sources.
