How much is 12 + 12?

The TUBE-TECH SMC 2BM Stereo Multiband Compressor features three independent optical stereo compressors. The signal is divided into three bands (Low, Mid & High) by 6 dB/octave x-over networks with 12 selectable frequencies: 60 – 1200 Hz for Low/Mid band and 6 selectable frequencies: 1,2 – 6,0 kHz for the Mid/High band.

Switchable crossover points ensure precise control of all three bands of opto-compression.

Independent band specific Threshold, Ratio, Attack, Release & Gain parameters make the SMC 2BM as flexible as it is accurate.
Gain controls are fitted with 12 position gold plated switches with 1dB/step. Threshold, Ratio, Attack, Release and Balance controls are fitted with potentiometers with 31 detents.



The design of the x-over networks optimizes the summing of all three bands, resulting in a flat frequency response (within +/-0,25 dB), when the gain controls for each band are set at the same level.

The three compressors feature Threshold, Ratio, Attack, Release and Gain and a display showing gain reduction. Master levels are set with Output Gain and Balance controls.

Both Input and Output are balanced and have fully floating transformers with a static screen. The power supply and the sidechain circuit is based on a solid state circuit. With the exception of the output stage all DC voltages are stabilised.
