REALIOS® 9135 Tungsten Lamp Compressor

The Smoothest Audio Compressor Ever

  • Gain reduction via a tungsten lamp
  • Super clean true RMS compression
  • Extraordinarily low distortion (less than 0.001%)
  • Stepped attenuators
  • Single space 500 series module

Imagine a compressor which doesn't use a photocell, diodes, FET, VCA, or variable-mu tube for gain reduction—only a tungsten lamp. Unlike the other technologies, a tungsten lamp adds no distortion to the audio signal making it a pristine audio device. Not only does a tungsten lamp not add distortion, but it is also a true RMS device which accurately tracks the audio level.

The REALIOS Tungsten Lamp Compressor combines high quality electronically balanced audio electronics with a tungsten lamp as a gain reduction element providing for smooth artifactfree, soft-knee leveling of even the most difficult program material. This is especially useful for vocals, bass, acoustic and electric guitars, and mixes.
