The TUBE-TECH CM 1A Compressor is an optical, all-tube compressor.
It features exactly the same tube circuit as our famous CL 1B Opto Compressor, but the action is different due to a different, carefully selected optical element and a fine-tuning of the control circuit.

This provides the CM 1A with an attack that enhances transients in a more punchy way, making it ideal for percussive material, yet still very well suited for vocals, bass guitar, etc.

The different optical element does NOT seriously change the the "classic" characteristics, known from the CL1B
The action of the CM1A places it somewhere between the LCA2B (Tube VCA) and the classic CL1B.
CM1A has been extremely well received by numerous top engineers.

Note: Due to the high quality of the TUBE-TECH RM Series power supply and the pristine audio circuits, the Modular Series products deliver exactly the same uncompromised sound quality as our 19” units.
