Crown CT475 300W ComTech DriveCore Amplifier, Crown's ComTech CT-475 amplifier delivers studio-grade sound in one rack-space with 4 channels of 75W. Performance is exemplary in every respect with Signal-to-Noise of better than 110dB and Total Harmonic Distortion below 0.05% across the full audio bandwidth.

Powering this remarkable amplifier is the pioneering technology of DriveCore, a chip built exclusively for Harman which replaces 500 individual components of previous designs, seamlessly integrating the amplifier drive stage into the power output. The end result is an ultra-energy efficient, highly reliable, one-piece audio amplifier circuit that exhibits the exemplary audio quality of a highly evolved Class AB design.


  • A signal-to-noise ratio of better than 110dB
  • Total harmonic distortion below 0.05% across the full audio bandwidth
  • Greater than 70dB crosstalk
  • Frequency response of 0.5dB
  • Up to 8 channels in a single rack-space
  • Weight of only 10 pounds (4.54 Kg) 
  • Over 90% efficient in the DriveCore amplifier stage
  • Power consumption of less than 1W when not in use (In Deep Sleep)
  • Green Mode delivers power when needed. Amplifier efficency increases by up to 10% when compared to typical class D amplifiers
  • 4 channel or 8 channel (4 inputs with 4 outputs or 8 inputs with 8 outputs)
  • Single rack space
  • Balanced 3-pin Barrier block-type/line inputs
  • 4-pin Phoenix-type speaker outputs
