4.0 DESCRIPTION OF CONTROLS
4.1 GATE SECTION
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.
