TUBE-TECH CL 1B
1-Kanal Kompressor/Limiter - The Industry Standard Vocal Compressor!
Der Tube-Tech CL 1B Kompressor ist ein vollständig auf Röhrentechnik basierender Optokompressor, der für Single-Track-Studioaufnahmen ausgelegt ist. Er ist, wie auch der CL 2A, hervorragend geeignet zur Komprimierung von Gesangsstimmen u.ä. und veredelt die Audiosignale mit seinem seidig weichen Röhrenklang.
FEATURES & TECHNICAL DATA
The TUBE-TECH CL 1B Compressor is an optical, all tube based compressor. The unit features a gain-reduction element, positioned immediately after the input transformer. It is controlled by the sidechain amplifier, which also contain the two time control circuits ? one for fixed and one for variable Attack/Release. The two time-controllers can either be used separately or combined. This circuit contains semiconductor OP-amps for the entire control.A dedicated Bus selector with three positions (Off, Bus 1, Bus 2) is used whenever you want to link several compressors together.
The gain-reduction element is followed by a tube-based push-pull amplifier with variable gain up to 30 dB. Input and output transformers have a static-screen between the primary and secondary wirings. Both Input and Output are balanced as well as fully floating.

FAQ: Opto Compressors CL 1A and CL 1B difference
- The circuit and functions are exactly the same. The amplifier section in the CL 1A is hardwired.
- In the CL 1B the transformers and the tubes are placed inside the unit on a printed circuit board. The control circuit is on a PCB in both units.
