• “ATTACK TIME”: this is the time it takes the compressor to react to an increase in theinput signal. It ranges between 0.5 and 100 ms.• “RELEASE TIME”: this is the maintenance time during which the compressor keepsacting, even when the level of the input signal has fallen below the threshold. It rangesbetween 0.01 and 10 s.• “RATIO”: this is the compression ratio. A ratio of 1:1 does not involve any variation inthe signal, as the level of the input signal is maintained at the output. A ratio of 1:1indicates that the level of an input signal which exceeds the threshold will be reduced tohalf at the output. The highest ratio available is 1:50, which will be used to implementsignal limiters. The limiter must reduce all signals exceeding a certain level to that level.• “GAIN“: this enables you to apply a general gain to the signal. This entails a generalincrease of the signal level, which will be especially noted at low input levels that areunder the threshold set. It ranges between 0 and 40dB.• “OK”: allows you to accept the created or edited configuration. A double confirmation isrequired.• “Cancel”: allows you to reject the created or edited configuration. No change you mayhave made is saved.4.3.4.2. Advanced configuration of Noise Gate.From the initial screen of the pre-sets advanced information menu (“Digital Sound Processes”)you can configure and activate/deactivate the Noise Gate operation.When you select the “Active” checkbox, the “Configure” button gets active and gives youaccess to the graphic display where the Noise Gate associated parameters can be modified.A noise gate is a dynamics processor that lets signals through whose level exceeds a certainthreshold, strongly attenuating the signal levels below that threshold and thus muting noise. Itenables its user to eliminate extraneous noise from a signal source, whether it is backgroundnoise in the studio, in the case of a microphone, or the background noise generated by aplayback device, for example, a tape.The available controls are:• “THRESHOLD“: determines the level above which signal is allowed through the gate.• “ATTACK TIME”: the time for the gate to react to a signal that is exceeding thethreshold.• “RELEASE TIME”: the time that the gate should remain open once the signal exceedingthreshold has disappeared.• “HOLD TIME”: the time that the gate should remain open when the signal falls belowthe threshold.AEQ CAPITOLUltra-compact digital audio mixer89
