compressor works like a limiter and prevents the output level from exceeding the Limit Threshold. Note: A 1:1
compression ratio will have no effect on the signal.
Release Time: As with the Input Compressor/Limiter, the Output Compressor/Limiter function responds
almost instantly to signals above the Threshold. The Release Time control sets the time it takes for the gain to return
to normal after the signal falls below the Limit Threshold.
Output Limit: The Output Limit control lets you select which inputs are compressed, and which are not. This
is a highly flexible feature, and can be used in some very advanced setups. To make the Output Compressor/
Limiter work like a conventional output compressor, make certain that all of the Output Limit controls are turned on.
Selectively turning off an Output Limit control enables its input to push all remaining inputs down whenever it
exceeds the Threshold. This is a specialized function and is offered only for those unique circumstances which
require it.
Tip: You don’t have to compress all inputs. You could restrict compression to an offending input, leaving
unchanged the signals that are unlikely to exceed the Limit Threshold. The Output Compressor/Limiter function
allows the mixer to maintain a more natural sense of dynamics, with fewer audible side-effects.
The following list shows the possible settings for each Output Compressor/Limiter function control. Note: All dB
settings are dBu.
Compressor/Limiter: On/Off
Limit Threshold: Off; –99½ dB to +25 dB in ½ dB steps
Compression Ratio: 1:1, 2:1, 4:1, 8:1, 16:1, 32:1,
∞ :1
Release Time: 0.2, 0.4, 0.6, 0.8, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 20, 30 seconds
Output Limit: On/Off
