Because the Compressor works by reducing levels, the overall volume of its output is
typically lower than the input signal. You can adjust the output level using the Gain
slider.
You can use the Auto Gain parameter to compensate for the reduction in gain
produced by compression, referenced to either –12 dB or 0 dB. Auto Gain sets the level
of gain (amplification) to a value of T—(T/R), where T = the Threshold and R = the
Ratio.
The Gain Reduction Meter displays the amount of compression occurring as the signal
plays. Its useful to watch how much your tracks are being compressed, and to make
sure they’re not being overly compressed.
When using the Platinum Circuit Type, the Compressor can analyze the signal using
one of two methods: Peak or RMS (root mean square). While Peak is more technically
accurate, RMS provides a better indication of how people perceive the signal’s
loudness. When using the Compressor primarily as a limiter, select the Peak button.
When compressing individual tracks, especially music tracks, select the RMS button.
If you activate Auto Gain and RMS simultaneously, the signal may be saturated. If you
hear any distortion, switch Auto Gain off and adjust the Gain slider until the distortion
is gone.
