 M.BAND COMP
Two input, two output 3-band compressor, with individual solo and gain reduction metering for
each band.
Premium Rack Processor Parameters
 Portico5033
This models an analog 5-band EQ made by the RND company.
 Portico5043
This models an analog compressor/limiter made by the RND company.
LIM.ATK 0-120 ms Attack time of the limiter
LIM.REL
*1
Release time of the limiter
LIM.KNEE 0-5 Knee of the limiter
LIM.BYP OFF/ON Bypasses the limiter
PRESENCE -10 to +10
Positive (+) values lower the threshold of the high band and raise the
threshold of the low band. Negative (-) values do the opposite. If this is
set to 0, the high, mid, and low bands will be affected in the same way.
LOOKUP 0.0-100.0 ms Lookup delay
MAKE UP OFF/ON Automatically adjusts the output level
*1. 6.0 ms-46.0 s (fs=44.1 kHz), 5.0 ms-42.3 s (fs=48 kHz)
Parameter Range Description

Parameter Range Description
Parameter Range Description
ALL BYPASS OFF, ON
Turns bypass on/off for the EQ. Even in the bypassed state, the signal will
pass through the input/output transformers and the amp circuit.

LF GAIN -12.0 to 12.0 dB Gain of the LF band
LMF IN OFF, ON Switches the LMF band on/off
LMF Q 0.70 to 5.00 Q of the LMF band
LMF FREQ 50.00 to 400.0 Hz Center frequency of the LMF band
LMF GAIN -12.0 to 12.0 dB Gain of the LMF band
MF IN OFF, ON Switches the MF band on/off
MF Q 0.70 to 5.00 Q of the MF band
MF FREQ 330.0 to 2500 Hz Center frequency of the MF band
MF GAIN -12.0 to 12.0 dB Gain of the MF band
HMF IN OFF, ON Switches the HMF band on/off
HMF Q 0.70 to 5.00 Q of the HMF band
HMF FREQ 1.80k to 16.0k Hz Center frequency of the HMF band
HMF GAIN -12.0 to 12.0 dB Gain of the HMF band

HF GAIN -12.0 to 12.0 dB Gain of the HF band
Parameter Range Description
IN OFF, ON
Turns bypass on/off for the compressor. When bypassed, the button will
be unlit. However even in the bypassed state, the signal will pass through
the input/output transformers and the amp circuit.
FB OFF, ON Switches between feed-forward type and feed-back type
