•
EQ STATUS: Bypass
or make
Active
EQ for this
source.
•
EQ HIGH MODE:
Choose between
shelf
or
band
pass
filter for high-frequency EQ.
•
EQ HIGH FREQUENCY:
Sets the active frequency
for high-band EQ. Variable from 1.25 kHz to 20 kHz.
If
EQ HIGH MODE
is set to
Shelf
, this setting de-
termines the top of the shelf. If
EQ HIGH MODE
is
set to
Band pass
, this sets the center frequency of
the BP filter (SmartQ determines the width of the BP
filter, as described above).
•
EQ MID FREQUENCY:
Sets the center frequency of
the midrange parametric band. Variable from 125
Hz to 2.0 kHz.
•
EQ LOW FREQUENCY:
Sets the center frequency of
the low parametric band. Variable from 20 Hz to 320
Hz.
•
EQ HIGH, MID & LOW GAIN:
Provides 40 dB of
adjustment range for boost or cut of the three para-
metric bands, from -25 dB to +15 dB.
The following options dealing with dynam-
ics processor settings apply to Mic, Codec and
Phone sources only. If applied to other source
types, these settings will be ignored.
•
NOISE GATE STATUS:
Turns the voice processor’s
noise gate on and off. Choose
Bypass
or
Active.
•
COMPRESSOR STATUS:
Turns the voice proces-
sor’s compressor functions on and off. Choose
By-
pass
or
Active.
•
DE-ESSER STATUS:
Turns the voice processor’s de-
esser module on and off. Choose
Bypass
or
Active.
•
NOISE GATE THRESHOLD:
Determines the point
at which the Noise Gate will operate (if set to
Ac-
tive
). Adjustment range is between 0dB and -50dB.
•
NOISE GATE DEPTH:
Sets the amount of noise
reduction that will be applied to the mic audio if
the noise gate is set to
Active
and the Noise Gate
Threshold is reached. Adjustment range is between
0dB and -30 dB.
COMPRESSOR THRESHOLD:
De-
termines the point at which the Compressor will op-
erate (if set to
Active
). Adjustment range is between
0dB and -30dB.
•
COMPRESSOR THRESHOLD:
Sets the threshold at
which compression will be applied to the mic audio.
Adjustment range is between -30 and 0 dB.
•
COMPRESSOR RATIO:
Sets the amount of com-
pression that will be applied to the mic audio. Ad-
justment range is between 1:1 and 16:1.
•
DE-ESSER THRESHOLD:
Determines the point at
which the De-Esser will operate (if set to
Active
).
Adjustment range is between 0dB and -20dB.
•
DE-ESSER RATIO:
Sets how aggressively the de-
esser will remove sibilance from the mic audio. Ad-
justment range is between 1:1 and 8:1.
•
COMPRESSOR MODE:
Toggles the voice compres-
sor between
Freeze
and
No Freeze
modes.
•
POST PROCESSING TRIM GAIN:
Some process-
ing settings will result in a reduction of overall signal
level. This setting allows you to adjust the amount
gain to compensate for any gain lost by compressor
processing.
What is this stuff? Radio engineers don’t need
a lesson in dynamics processing, but for the ben-
efit of any jocks reading this, here’s a quick ex-
planation of what these controls can do.
A Gate is a dynamics device whose function
is to remove unwanted audio material below a
certain threshold. A gain circuit is employed to
raise or lower the volume of the audio signal;
when the signal falls below a certain set thresh-
old, the audio level drops down to a predeter-
mined level. The reason they are called gates
is because when they “close” it sounds as if
the audio has suddenly stopped, or has been
“gated.” You might use this on a mic channel to
eliminate background noise during times when
you’re not speaking.
Threshold settings determine at what level the
processor will begin working. For example, on
