Tube-Tech CL 1B Compressor
TUBE-TECH CL 1B Compressor 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.
Features:
- 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 relay
