TubeTech CL 1B All Tube Mono Compressor

The Tube-Tech CL 1B is an optical, all tube basedcompressor targeted at single-track studio recordings. It isequally suited for delicate vocal recordings as well as criticalinstrument recordings such as lead guitar, drum solos etc.

The Tube-Tech CL1B features a gain-reduction element, positionedimmediately after the input transformer. It is controlled by thesidechain amplifier, which also contain the two time controlcircuits – one for fixed and one for variable Attack/Release. Thetwo time-controllers can either be used separately or combined.This circuit contains semiconductor OP-amps for the entire control.The gain-reduction element is followed by a tube-based push-pullamplifier with variable gain up to 30 dB. A dedicated Bus selectorwith three positions (Off, Bus 1, Bus 2) is used whenever you wantto link several compressors together. Input and output transformershave a static-screen between the primary and secondary wirings.Both Input and Output are balanced as well as fully floating.

The CL 1B has proven its value by adding that sought-aftervintage warmth and realism to the most demanding studio tracks.

The Tube-Tech CL 1B main features include:

• Unique low distortion gain-reduction element
• All tube-based push-pull amplifier
• Multiple interconnection of several compressors via twobusses
• VU-meter for monitoring input, compression and output
• Continuously variable attack and release time
• Gain Range (off to +30 dB)
• Variable Threshold (off to -40 dBu)
• Frequency response @ -3 dB: 5 Hz to 25 kHz
• Low noise: < -75 dBu @30 dB gain
• Clickless bypass switch
