  • Page 35: Compressor/Limiter

    Sets the slope rate when using a low or high shelf type filter. 4.9 Compressor/Limiter The DriveRack 260 also offers Compression and Limiting modules. The Compressor is a full bandwidth Stereo Compressor inserted prior to the Crossover. The Compressor is the perfect tool for tightening uneven signal sources, providing a more even mix.
  • Page 36 Release 360 dB / Sec to 5 dB / Sec Release is how fast the 260 comes out of compression. The release is in dB per second. For example, if release is set to 5 dB /sec, and the signal is at 10dB of gain reduction, the release time is 2 seconds. Too fast a release time can result in an audible volume jump, while too slow a release time can result in compression of signal that is not above threshold.
  • Page 37 Attack .01 to 200 m Sec (per band or global) This is the speed at which the 260 limiter starts to limit the signal once it has crossed the threshold. Set the attack time longer for lower frequency bands, and shorter for higher frequency bands.
