The Hold control sets the amount of time the gate is held open after the signal passes below the threshold point Release 360 to 5 dB Release sets the speed at which the gate closes or attenuates when the end of the Hold time is reached Max ATT 0 to Inf dB This sets the maximum amount of attenuation for the gate 30 DriveRack 260 User Manual dbx 4 5 Automatic Gain Control AGC The AGC is used to keep the average level of signal at a constant level This is done by selecting a desired Target output level and Window The AGC keeps the signal within the Window about the selected Target by slowly adjusting the gain The maximum gain that can be applied to the signal is selected by the Gain parameter When the input signal falls below the Low Threshold the AGC releases the gain and returns to unity This prevents the AGC from adding gain when there is no signal present and raising the system noise floor High level signals are reduced by a fast limiter to prevent distortion by clipping The AGC Threshold meters show what region of the AGC the input signal is in The T yellow indicates the signal is within the Window A red indicates the signal is going into the Limiter A green indicates the AGC is adding maximum Gain and is at or below the Window When the Threshold meter is off the signal is below the Low Threshold Target 10dB Window 54 Gain 15dB Low Threshold 40dB 4 Output In
