The CL2A is an all rounder of a 2 channel opto compressor. It deliveres that smooth and musical compression that TUBE-TECH is known for. Use it for keys, guitars, vocals, mixbus, the result is always musical and transparent.
CL2A is based on the CL1B, but it's not a stereo CL1B! Some differences exist between the two units. The tube circuit is the basically same, with the only difference being that the input transformer and the tube amps in the CL2A delivers a more "normal" amount of gain compared to the CL1B. The control circuit has been changed so the CL2A's max release time is two seconds. The CL2A features a different optical element, with a reasonably similar action to the element in the CL1B. The CL2A has a little more "round" character to the compression, compared to the CL1B, but has kept the very smooth action, the CL1B is famous for. |
CL 2A Technical Description and Features
The TUBE-TECH CL 2A Two-Channel Optical Compressor is an all tube based compressor.
The CL 2A features two independent optical compressors. The optical gain reduction element is placed after the input transformer and then followed by an all tube-based output amplifier with a +10 dB gain. A switch with three positions (Link 1, Off, Link 2) is used whenever you want to use the two separate compressors in stereo mode or link several compressors together. The two link busses are identical.
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 anode voltage for the output stage all DC voltages are stabilized.
