Description

The industry-standard Tube-Tech CL 1B is a mono compressor with an all-tube Class A/B (push-pull) amplifier and unique low-distortion optical detector

The Tube-Tech CL 1B is an all-tube, single-channel opto-compressor that has become as ubiquitous on lead vocals as the preamp made by that British gentleman (whose name starts with N and rhymes with “eve”), who shall remain anonymous. Tube-Tech’s best-selling compressor, the CL 1B is known for its incredibly smooth, musical compression, even at extreme settings. (If you can make the CL 1B sound bad, consider a career in the demolition business.) The CL 1B, due its all-tube design, also adds a rich, euphonic timbre to vocals, and like its gain reduction function, is never over-the-top or performance-compromising.

  • Unique, low-distortion optical gain-reduction element
  • All-tube push-pull amplifier
  • Linkable to multiple CL 1Bs via two buses
  • VU meter shows input level, gain reduction, or output level
  • Noiseless In/Out switch
  • Conductive plastic potentiometers
  • Transformer-balanced, fully floating inputs and outputs

INSIDE THE BOX—Tube-Tech CL 1B

CL 1B technical elements

The Tube-Tech CL 1B is an optical compressor, with a discrete all-tube audio path (not simply solid-state optical compressor followed by a tube gain stage).

The CL 1B’s gain-reduction element is positioned immediately after the input transformer. It’s controlled by the sidechain amplifier, which also contains two time control circuits; one fixed, the other for variable attack and release. The time controllers can either be either be used separately or in combination. In fixed mode, the attack is fast and release is program dependent. In combination, the attack is fast, while the release can be controlled manually. This circuit contains semiconductor OP-amps for overall control. A dedicated Bus selector with three positions (Off, Bus 1, Bus 2) is enables you to link several compressors together.

The CL 1B’s gain-reduction element is followed by a tube-based, push-pull amplifier with variable gain up to 30dB. Input and output transformers have an electrostatic shield between the primary and secondary wiring, which sends primary noise to ground. The shield will not re-radiate the noise signal, and also provides electromagnetic noise reduction. Additionally, to further prevent noise interference, both the input and output are balanced as well as fully floating, so there is no current path between I/O and ground. This design magnetically isolates the circuitry from external connections.

CL 1B in operation 

In operation, the Tube-Tech CL 1B is as easy and intuitive. Whether you’re compressing vocals, bass, acoustic guitars, or keys, just dial in what you need to make the track stable in the mix, or to bring out subtleties, and the CL 1B does the rest—without distortion, muddiness, or obvious artifacts, always maintaining clarity, even if you have to hit it hard. This is why the Tube-Tech CL 1B is at the top of must-have lists for every serious audio pro (who doesn’t already have one), and heard on innumerable best-selling, best-sounding recordings in all genres.
