■
U76
This models a well-known vintage compressor/limiter used in a wide range of situations.
■
Opt-2A
This processor emulates a well-known vintage model of vacuum tube opto compressor.
■
EQ-1A
This processor emulates a vintage EQ that’s considered a classic example of a passive EQ.
■
Dynamic EQ
This is a newly developed equalizer that dynamically changes the EQ gain in response to the input
signal, controlling the amount of EQ cut or boost in a way similar to a compressor or expander.
Parameter
Range
Description
INPUT
–96.0 to 0.0 dB
Input level
OUTPUT
–96.0 to 0.0 dB
Output level
ATTACK
5.50 to 0.10 ms
Attack time of the compressor. Turning this all the way to the right produces
the fastest attack.
RELEASE
1100.0 to 56.4 ms
Release time of the compressor. Turning this all the way to the right produces
the fastest release.
RATIO
ALL, 4, 8, 12, 20
Switches the compression ratio. Pressing ALL produces the strongest effect.
METER
OFF, +4, +8, GR
Switches the meter display
Parameter
Range
Description
GAIN
–56.0 dB to 40.0 dB
Output level
PEAK REDUCTION
–48.0 dB to 48.0 dB
Amount of gain reduction
RATIO
2.00 to 10.00
Compression ratio
METER SELECT
10, GAIN REDUCTION,

Switches the meter display
Parameter
Range
Description
LOW FREQUENCY
20, 30, 60, 100 Hz
Frequency range of the low range filter
(LOW) BOOST
0.0 to 10.0
Boost amount of the low range filter
(LOW) ATTEN
0.0 to 10.0
Attenuation amount of the low range filter
HIGH FREQUENCY
3k, 4k, 5k, 8k, 10k, 12k, 16k Hz
Frequency range of the high range filter
(HIGH) BOOST
0.0 to 10.0
Boost amount of the high range filter
(HIGH) BAND WIDTH
0.0 to 10.0
Band width of the high range filter
(HIGH) ATTEN SEL
5k, 10k, 20k Hz
Frequency range attenuated by the high range filter
(HIGH) ATTEN
0.0 to 10.0
Attenuation amount of the high range filter
IN
OFF, ON
Turns the processor on/off. If this is off, the filter section
will be bypassed, but the signal will pass through the
input/output transformers and the amp circuit.
Parameter
Range
Description
BAND ON/OFF
OFF, ON
Turns the corresponding band on/off
SIDECHAIN CUE
OFF, ON
If this is on, the sidechain signal that controls the dynamics will
be sent to the CUE bus for monitoring.
SIDECHAIN LISTEN
OFF, ON
If this is on, the sidechain signal that is linked to the dynamics
will be output to the bus (such as the STEREO bus or a MIX/
MATRIX bus) to which the inserted channel is being sent.
FILTER TYPE
Low Shelf, Bell, Hi Shelf
Switches the type of equalizer and sidechain filter
FREQUENCY
20.0 to 20.0k Hz
Frequency controlled by the equalizer and sidechain filter
Q
15.0 to 0.50
Q of the equalizer and sidechain filter
THRESHOLD
–80.0 to 10.0 dB
Threshold value at which processing begins to apply
RATIO
∞ : 1 to 1 : 1.50
Sets the boost/cut ratio relative to the input signal.
MODE
BELOW, ABOVE
Specifies whether the processor will operate when the
sidechain signal exceeds the threshold setting (ABOVE) or
when it falls below the threshold setting (BELOW)
ATTACK/RELEASE
FAST, SLOW, AUTO
Attack time/release time for when compression or boost is
applied
