■ U76
This models a well-known vintage compressor/limiter used in a wide range of situations.
Parameter Range
INPUT –96.0 to 0.0 dB Input level
OUTPUT –96.0 to 0.0 dB Output level
Attack time of the compressor. Turning this all the way to the right produces
ATTACK 5.50 to 0.10 ms
the fastest attack.
Release time of the compressor. Turning this all the way to the right produces
RELEASE 1100.0 to 56.4 ms
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
■ Opt-2A
This processor emulates a well-known vintage model of vacuum tube opto compressor.
Parameter Range
GAIN –56.0 dB to 40.0 dB
PEAK REDUCTION –48.0 dB to 48.0 dB
RATIO 2.00 to 10.00
OUTPUT+10, GAIN REDUCTION,
METER SELECT
OUTPUT+4
■ EQ-1A
This processor emulates a vintage EQ that's considered a classic example of a passive EQ.
Parameter Range
LOW FREQUENCY 20, 30, 60, 100 Hz
(LOW) BOOST 0.0 to 10.0
(LOW) ATTEN 0.0 to 10.0
HIGH FREQUENCY 3k, 4k, 5k, 8k, 10k, 12k, 16k Hz
(HIGH) BOOST 0.0 to 10.0
(HIGH) BAND WIDTH 0.0 to 10.0
(HIGH) ATTEN SEL 5k, 10k, 20k Hz
(HIGH) ATTEN 0.0 to 10.0

Attenuation amount of the low range filter
Frequency range of the high range filter

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.
■ 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
BAND ON/OFF OFF, ON
SIDECHAIN CUE OFF, ON
SIDECHAIN LISTEN OFF, ON
FILTER TYPE Low Shelf, Bell, Hi Shelf
FREQUENCY 20.0 to 20.0k Hz
Q 15.0 to 0.50
THRESHOLD –80.0 to 10.0 dB
RATIO ∞ : 1 to 1 : 1.50
MODE BELOW, ABOVE
ATTACK/RELEASE FAST, SLOW, AUTO
246
Description
Turns the corresponding band on/off
If this is on, the sidechain signal that controls the dynamics will
be sent to the CUE bus for monitoring.
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.
Switches the type of equalizer and sidechain filter
Frequency controlled by the equalizer and sidechain filter
Q of the equalizer and sidechain filter
Threshold value at which processing begins to apply
Sets the boost/cut ratio relative to the input signal.
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 time/release time for when compression or boost is
applied
