Noise gates are particularly useful for preventing mic rumble, wind
noise, or hum from getting to tape in your recordings, or for gating
drum kits to prevent mic bleed.
DESCRIPTION
INPUT LEVEL - Controls the signal input level fed to the Module. Varies from OFF to 100%.
OPEN THRESHOLD - Sets the level at which the gate begins to open at the rate set by ATTACK. Both
THSHO and THSHC are independent controls. This gives you the option to do nifty stuff like setting
THSHO higher than THSHC, which could be used to let guitar notes sustain longer while still retaining the
noise-gating characteristics of the gate when closed.
CLOSE THRESHOLD - Sets the level at which the gate begins to close at the rate set by RELEASE. Both
THSHO and THSHC are independent controls. THSHC cannot be set higher than THSHO.
ATTENUATION (Gate) - Adjusts how far the signal level is lowered (attenuated) when the gate is closed.
The higher you set ATTN, the lower the noise floor of the source when the gate is closed. Varies from 0%
to 100%.
The DELAY control is used to open the gate more quickly than 'normal' gates are capable. This is a
very cool function that allows your gates to capture and preserve even the fastest attack transients.
For example, you could use this control with great success on snare drums, whose characteristic initial
"whack" can be chopped off by other gates because the gate spends the first 6 to 8 milliseconds trying
to react to the sharp increase in levels. When you use this control in the Studio Quad, however, the end
result is that the gate is already open when the sound arrives (up to 10 milliseconds in advance),
preserving the integrity of the entire source. Ranges from 0.1 to 10 milliseconds.
Controls how quickly the gate opens after the signal level reaches THSHO. Because gates with slow
attack times do not open immediately, they can be used in conjunction with pitch shifters or detuners to
create special effects or simulate slow synth pads using other instruments. Varies from 0 to 2 seconds.
The setting of HOLD determines how long the gate remains open after the signal level falls below THSHC.
Long HOLD settings can be used to prevent the gate from "stuttering", or opening and closing rapidly,
during soft passages when average signal levels are just above or below the THSHC setting. Varies
from 0 to 500 milliseconds.
RELEASE - Determines how quickly the gate closes after the signal level falls below THSHC. When used
in conjunction with long HOLD settings, this control can be used to further prevent stuttering, or to make
the closing of the gate less obtrusive. Varies from 0 to 2 seconds.
