THRESHOLD
The Threshold control determines the compressor threshold value. The value scale for the THRESHOLD control indicates the level in dBu. Turning fully CCW provides no control, and fully CW provides compression starting at a level of approx.
RATIO
The RATIO control is used to set the ratio between the original signal and the compressed signal. A ratio of 1:4 means that a level increase of 4 dB on the input results in an output change of 1 dB. The more the control is turned CW, the more ‘dense’ the sound becomes. Turned fully CW the unit works as a limiter.
ATTACK
The Attack control determines the time the compressor needs to achieve a reduction of 63% at a level jump of 20 dB. When turned fully CCW this time is approx. 100 ms, and turned fully CW the time is approx. 0.9 s. When Progressive Time Control is enabled the effect is somewhat different: now you are determining the degree to which the fast signal jumps are compressed, whereas the attack time is automatically optimized (adapted). Progressive Time Control mode is often advantageous , since the attack time is only as fast as is necessary for the respective signal. The result is considerably unob- trusive and thus more musical compression behavior without undesired side- effects.
RELEASE
The RELEASE control is used to set the time the compressor needs to back off by 63% to the original value. Turned fully CCW this time is approx. 30 ms, or approx. 2 s for fully CW. If Progressive Time Control is enabled, the Release control is used to set the average value to which the automatic release time is set back. The more the control is turned CW, the slower the averaging. This gives much better results than with the conventional method of rigid release time control especially with complex musical material.
MAKE UP GAIN
The MAKE UP GAIN controller is used to change the output level within a range of approx.
