The TUBE-TECH CL 1B is an exceptional all-tube optical mono compressor, renowned for its musical and smooth compression, even at extreme settings, retaining the source's clarity—a standout feature compared to other compressors. Its user-friendly design allows for intuitive operation, ensuring you achieve your desired results quickly and effortlessly.

This compressor employs a gain-reduction element placed right after the input transformer, controlled by the sidechain amplifier, housing two time control circuits—one for fixed and the other for variable Attack/Release. These time-controllers can be used independently or together, and the entire control circuit utilizes semiconductor OP-amps.

PSU works on 115-230V, EU power cord included.
