The TUBE-TECH CL 2A is an all-tube optical compressor with two independent,linkable channels.

CL 2A is a great compressor on all sources, and it is widely known as anexcellent “problem solver” when delicate gain control is called for.

Use it on keyboards, guitars, vocals or even on the mix buss – the resultis always musical, smooth and transparent. Among engineers, the CL 2A is lovedbecause of its ability to keep instruments at their right place in the mix,while still retaining their dynamics.

Features and Technical Specifications

CL 2A is a two channel all-tube opto compressor, featuring two independentchannels. The optical gain reduction element is placed after the input transformerand followed by an all tube-based output amplifier with a +10 dB gain.

A link switch is provided for use of the two separate compressors in stereomode or for linking several compressors together. Both Input and Outputare balanced and have fully floating transformers with a static screen.

The power supply and the sidechain circuit are based on solid statedesigns. With the exception of the anode voltage for the output stage, all DCvoltages are stabilized.
