8.13. Gate Settings
The gate function allows the input signal to be passed,
attenuated or cut depending on its signal level.
The gate allows the signal to pass when open, and
attenuates or cuts the signal when closed. The gate opens
when the input signal reaches a level above the Threshold
plus Hysteresis parameter (half the Hysteresis) as shown in
the figure at right. Once open, the input signal must reach a
level below the Threshold minus Hysteresis parameter to
close.The Ducker function (p. 38) and the NOM attenuation
function (p. 39) are controlled by the gate's open/close
operations.

When any of the following screens is displayed, the gate function for the displayed channel can be
enabled or disabled with the function ON/OFF key. When enabled (ON), the function ON/OFF

PARAMETER
PUSH-ENTER
CHANGE
• Rotate the Setting knob to set the threshold level.
Parameter setting range: –50 to +20 dB in 1 dB steps
• Pressing an Input channel selector key permits the gate threshold
level to be set for that channel. The [IN 1] indication changes to
the selected channel number indication.
• The setting screen reverts to the Input/Output Gain Setting
screen when the shift key is pressed.

PARAMETER
PUSH-ENTER
CHANGE
• Rotate the Setting knob to set the hysteresis (the difference
between the input signal levels used to open and close the gate).
Parameter setting range: 0 to +10 dB in 1 dB steps
• Pressing an Input channel selector key permits the gate
hysteresis to be set for that channel. The [IN 1] indication
changes to the selected channel number indication.
