19 RIVAGE PM series Data List
■ Portico 5045
Models the Primary Source Enhancer made by Rupert Neve Designs.
■ 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.
■ Comp276
This compressor emulates the characteristics of an FET gain reduction commonly used in recording
studios. It will produce a thick, strong frame sound suitable for drums and bass.
■ Comp276S
This compressor emulates the characteristics of an FET gain reduction commonly used in recording
studios. It produces a thick, strong frame sound suitable for drums and bass. You can link and control
the L and R channel parameters.
Parameter Range Description
PROCESS ENGAGE OFF, ON
Turns the enhancement circuit on/off. Even when this is off, the
signal passes through the audio transformer and discrete amp
circuit.
RMS/Peak RMS, Peak Operation mode of the level detector.
TIME CONSTANT A, B, C, D, E, F Attack and release time.
THRESHOLD –42.0 to –12.0 dB Threshold level.
DEPTH 0.0 to –20.0 dB Amount of attenuation for signals below the threshold level.
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
(REDUC
*1
)
*1. Actual indication in the screen encoder access field
–48.0 dB to 48.0 dB Amount of gain reduction
RATIO 2.00 to 10.00 Compression ratio
METER SELECT
OUTPUT+10, GAIN REDUCTION,
OUTPUT+4
Switches the meter display.
Parameter Range Description
INPUT 1 –180 to 0 dB Adjusts the CH1 input level.
OUTPUT 1 –180 to 0 dB Adjusts the CH1 output gain.
RATIO 1 2:1, 4:1, 8:1, 12:1, 20:1 Ratio for CH1 compressor
ATTACK 1 0.022–50.4 ms Attack time for CH1 compressor
RELEASE1 10.88–544.22 ms Release time for CH1 compressor
MAKE UP1 OFF, ON
Automatically corrects output gain reduction when CH1 compressor is
applied.
SIDEHPF1 OFF, ON
When the HPF in the side chain of the CH1 compressor is turned on, the
compression applied to the low range will be weakened, thus emphasizing
the low range.
Parameter Range Description
INPUT –180 to 0 dB Adjusts the input level.
OUTPUT –180 to 0 dB Adjusts the output gain.
RATIO 2:1, 4:1, 8:1, 12:1, 20:1 Ratio of the compressor
ATTACK 0.022–50.4 ms Attack time of the compressor
RELEASE 10.88–544.22 ms Release time of the compressor
MAKE UP OFF, ON
Automatically corrects output gain reduction when the compressor is
applied.
SIDE HPF OFF, ON
When the HPF in the side chain of the compressor is turned on, the
compression applied to the low range will be weakened, thus emphasizing
the low range.
