THRESHOLD
control
Sets the signal level at which the gate opens, letting signals pass. Most sensitive (-50dB) setting is
counter-clockwise (CCW). Turning Threshold fully clockwise to +20dB effectively stops the gate
opening.
If the Gate appears not to fully open try reducing the Threshold level (CCW).
RELEASE
control
The RELEASE control sets the rate at which the gate closes (attenuates the signal) after the input
signal has fallen below the Threshold level. Minimum release time (30mS) is with the control CCW
and maximum (3S) with it fully CW.
Short release times used with long decay sounds (such as bass guitar) can cause the gate to
repeatedly close and open (chatter). To avoid this effect, lengthen the RELEASE time. A more
sensitive THRESHOLD setting will also reduce the chances of chatter.
Short Release settings will give an abrupt ending to gated signals which may sound un-natural on
signals such as vocals, string sounds etc.
N.B. The use of fast attack or release times with some signals may result in an audible click. This is
not a fault of the gate design but an acoustic effect caused by introducing a fast rising or falling edge
to the signal waveform.
Attack time on the GCX20 is fixed at 1mS.
BYPASS
switch
Pressing BYPASS disables the gate.
In LINK mode Channel 2 BYPASS is in-operative.
GATE
led
Lights to show the gate is open and stays lit whilst the input signal is above Threshold.
The led still indicates Gate open-Gate closed but is dimmed when BYPASS is 'in'.
Range on the GCX20 is fixed at -80dB so gated signals are effectively muted.
