Tube-Tech CL-1B

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

The Tube-Tech CL1B 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. The gain-reduction element is followed by a tube-based push-pull amplifier with variable gain up to 30 dB. A dedicated Bus selector with three positions (Off, Bus 1, Bus 2) is used whenever you want to link several compressors together. 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.

The CL 1B has proven its value by adding that sought-after vintage 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 two busses
  • 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
