Dynamics 139 A 45-degree line means that the input signal level equals the output signal level, in other words, the Gate is having no effect. The output meter displays the level of the output signal.

On the Stereo Gate, the trigger signal is derived by mixing the signals from both inputs, so the higher of the two input signals will activate the Gate. When SIDECHAIN is on, the Gate is triggered by the signal connected to the sidechain input. THRESHOLD-This determines the level of the trigger signal required to open and close the Gate. Trigger signals above the threshold cause the Gate to open, allowing the input signal to pass unaffected. Trigger signals below the threshold, however, cause the Gate to close, preventing the passage of the input signal. RANGE-This determines the level to which the Gate closes. Think of it as a brick holding a garden gate open so that a certain amount of signal always flows through. For a setting of -70 dB, the Gate closes completely when the trigger signal falls below the threshold. For a setting of -30 dB, however, the Gate half closes. For a setting of 0 dB, the Gate has no effect. When signals are gated abruptly, the sudden disappearance can sometimes sound odd. This parameter causes the Gate to reduce the signal level rather than cut it completely.

Slow attack times can be used to remove the initial transient edge of percussive sounds. Too slow an attack time makes certain sounds appear backwards. HOLD-This determines how long the Gate stays open once the trigger signal has fallen below the threshold level. DECAY-This determines how fast the Gate closes once the hold time has expired. A longer decay time produces a more natural gating effect, allowing the natural decay of an instrument to pass through. DME32-Owner's Manual
