Gate Key Filter (StudioLive
24.4.2 only). Sets and Displays
the Frequency at Which the Gate
Will Open.
This encoder sets, and the meter
displays, the frequency at which
the gate will open. Setting a
specific frequency, in addition
to a specific decibel level,
provides more sonic shaping.
Power User Tip: A properly set
Key Filter on a gate can greatly
improve the overall sound quality
of a mix. For example, if you
are miking a bass amp and are
picking up a bit of the kick drum
from that mic, setting the gate
to open at the frequency of the
kick drum, combined with a fast
attack and release, can tighten
the rhythm section. Increase the
release time to loosen the feel.
Gate Threshold. Sets and
Displays the Threshold of the
Gate for the Selected Channel.
This encoder sets, and the meter
displays, the gate threshold
for the selected channel. The
gate threshold sets the level
at which the gate opens.
Essentially, all signals above the
threshold setting are passed
through unaffected, whereas
signals below the threshold
setting are reduced in level by
the amount set by the range
control (StudioLive 24.4.2 only).
If the threshold is set fully
counterclockwise, the gate
is turned off (always open),
allowing all signals to pass
through unaffected. You can set
the threshold from 0 to -56 dB. Gate Range (StudioLive 24.4.2
only). Sets and Displays the
Range of the Gate.
This encoder sets, and the
meter displays, the amount
of gain reduction that the
gate will produce. The range
can be set from 0 to -86 dB.
Range control is not available
when using the Expander.
Gate Attack (StudioLive 24.4.2
only). Sets and Displays the Gate
Attack Setting for the Selected
Channel.
This encoder sets, and the
meter displays, the rate at
which the gate opens on the
selected channel or output.
You can set the attack time
from 0.2 to 150 ms.
Power User Tip: A fast attack
rate is crucial for percussive
instruments. Slow-rising signals
such as vocals and bass guitar
require a slower attack; with these
signals, a faster attack can cause
an audible click. All gates have the
ability to click when opening but a
properly set gate will never click.
