Manufacturer's Description from Tube-Tech

The TUBE-TECH SMC 2B Stereo Multiband Compressor features three independent optical stereo compressors. The signal is divided into three bands (Low, Mid & High) by 6 dB/octave x-over networks with variable frequencies: 60-1200 Hz for Low/Mid band and 1,2-6 kHz for the Mid/High band.

The design of the x-over networks optimizes the summing of all three bands, resulting in a flat frequency response (within +/-0,25 dB), when the gain controls for each band are set at the same level. The three compressors feature Threshold, Ratio, Attack, Release and Gain and a display showing gain reduction. Master levels are set with Output Gain and Balance controls.

Both Input and Output are balanced and have fully floating transformers with a static screen. The power supply and the sidechain circuit is based on a solid state circuit. With the exception of the output stage all DC voltages are stabilised.

Product Features

  • The world’s first “all tube based” multiband compressor design
  • Three bands per channel with variable crossover frequencies between bands
  • Stereo sidechain with variable Threshold, Ratio, Attack, Release and Gain controls for all three bands
  • Master Output Gain (off to +10 dB)
  • Balance Control (+/-1.5 dB)
  • LED display showing compression
  • Freq. response @ -3 dB: 5 Hz to 60 kHz
  • Low noise: < -60 dBu @10 dB gain
  • Conductive plastic potentiometers
  • Clickless bypass relay

Mastering Version Includes:

  • Potentiometers with 31 detents for Threshold, Ratio, Attach, Release and Balance
  • Gain controls with 12 positions gold plated switches
  • Frequency switches with 6 positions gold plated switches

About Manufacturer

STATEMENT It is our mission to ensure the engineer has confidence in his working tools and feels comfortable working with them. To achieve this, it is our job to bring out the very best in the tubes, as well as continuously strive to offer the professional audio engineer outboard equipment of sublime quality ? both in terms of sound and reliability. Lydkraft ApS was founded in 1977 by partners John G. Petersen, Niels Wors?e and Karsten Bruun. Originally the core business of the company was PA, which was a successful venture until 1980, when the partnership was cancelled ? and Mr. Petersen decided to take Lydkraft on his own shoulders. The company was relocated to the interimistic surroundings of Mr. Petersens garage.... Mr. Petersen now redefined the business focus of Lydkraft: He terminated the PA business entirely and focused his efforts towards design, development and manufacturing. During this period small production runs of direct boxes, mixing desks and speaker systems were manufactured as well. In the early 80?s, the demand for vintage tube gear was increasing at a rapid pace. But at the same time tube equipment became more and more scarce by the day. The idea of taking on development & manufacturing of recording equipment with tubes came about in 1984. The first tube-based unit bearing the name TUBE-TECH was developed as an almost direct copy of the Pultec EQP 1A. The tubes of TUBE-TECH Program Equalizer PE 1A glowed for the first time in 1985 and the very first shipment containing 30 units stood ready in June 1985. Next in line was the TUBE-TECH PE 1B and TUBE-TECH Midrange Equalizer ME 1A, soon followed by the TUBE-TECH Compressor Limiter CL 1A and the TUBE-TECH Microphone Preamp MP 1A in 1987.
