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 MMC1A makes wonders in recording or mixing difficult sources like very dynamic voices or instruments where the tonal caracter 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 possibillities in recording and mixing full range sources.

• Mic. Gain in 2 dB and 10 dB steps
• Selectable mic. impedance 600/1200/2400
• Phantom Power (+48V)
• Phase reversal
• 20 dB pad
• High impedance Direct Input
• Separate line input (gain +/- 10 dB)
• Lowcut filter (20 Hz / 40 Hz/off)
• Optical gain reduction elements
• Cont. variable Threshold, Attack, Release
• Ratio 2:1 to 10:1
• LED display showing gain reduction
• Low, Mid, High Output Gain: off to +10 dB
• Variable X-over frequencies
• Low noise < -80 dBu @ 0 dB gain
• Master Output Gain: off to +10 dB

The MMC 1A  encompasses a complete front-end, including 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.
