Stereo Compressor

The Kultube is a stereo compressor with a broad range of control facilities that cover all typical compressor applications. From improved stereo mixes in the “MIDI Studio“ to surround mastering with several devices connected, all jobs can be undertaken to the highest degree of sound quality.

  • Stereo compressor with discrete, Class A gain components (instead of industrial VCAs)
  • Single track or subgroup/summed signal processing in studio and live recording
  • Stereo and multi-channel applications 
  • Achieve massive attacks and increased loudness without side-effects
  • Progressive Time Control: interactive automation of attack and release times, the permanent reaction to the input signal ensures musical perfection (no fixed automation presets)
  • Adjustable tube saturation with automatic output level adjustment
  • Selectable soft or hard knee characteristics
  • Unique decompression mode
  • Large VU meter displays gain reduction or (mono summed) output level
  • Switchable side-chain inputs on the front panel
  • Slave mode for multi-channel operation
  • Options: 24/192 AD converterI/O transformers from Lundahl
  • Made in Germany
