2.2 Compressor Controls
Threshold
The Compressor Threshold sets the level at which compression begins. The below and above LED’s over the Threshold knob indicate whether the input signal is below or above the Threshold setting. When the signal is above the Threshold setting, it becomes ‘eligible’for compression. Basically, as you turn the Threshold knob
Ratio
Ratio sets the compression slope. This is defined as the output level versus the input level. For example, if you have the Ratio set to 2:1, any signal level above the Threshold setting will be compressed at a compression ratio of 2:1. This simple means that that for every 1dB of level increase into the compressor, the output will only increase ½ dB, thus producing a compression Gain reduction of 0.5 db. As you increase the Ratio, the compressor gradually becomes a limiter. A limiter is defined as a processor that limits the level of signal to the setting of the Threshold. For example, if you have the
