  • Page 3 If you hear feedback every time the music stops, you must lower the overall level of the system. About stereo compression For great technical information on stereo processing, see the dbx white paper called True RMS Power Summing®, written by Roger Johnson, Director of dbx Engineering. Otherwise read on...
  • Page 4 If the Gain Reduction meter shows that the input signal is being attenuated by -6dB, then the Output control generally should be set around +6dB. This control is disabled if the [BYPASS] button is pressed. ¨ Page 3 Compression 101 - November 1998...
  • Page 5 Threshold set so that one GAIN REDUCTION LED (-1 dB) lights during the softest passages with signal (usually around 11 o’clock) Ratio set for 2:1 Attack set fairly fast (8-9 o’clock) Release set between 10 and 12 o’clock Raise output to compensate for gain reduction ¨ Page 4 Compression 101 - November 1998...
  • Page 6 Many compressors allow you to perform de-essing on a track by using a sidechain. By placing an equalizer in the sidechain, you can set the compressor so that only certain frequency ranges trigger the unit to start compressing. ¨ Page 5 Compression 101 - November 1998...
  • Page 7 “pumping” as the lower level signals (noise included) slowly fade back up to their normal signal level. the secret to avoiding these problems is to achieve a balanced release time on the input signal. ¨ Page 6 Compression 101 - November 1998...
