Portico 5043
Portico 5043, like Portico 5033, is a processor that emulates RND’s analog compressor. The
actual 5043 compressor is equipped with the same input/output transformer as that of the
5033 EQ, delivering a natural, analog-like tonality and effect. It enables you to obtain a range
of results from hard compression to natural sound, and is suitable for a broad range of audio
sources ranging from drums to vocals. The most notable feature of this model is that you can
switch the gain reduction type. You can choose either an FF (Feed-Forward) circuit type
(which is the current mainstream), or an FB (Feed-Back) circuit which was typically used in
vintage compressors. This allows you to create sounds with various characteristics as
appropriate for your applications.
1 IN button
Turns the compressor’s bypass on or off. When the compressor is bypassed, the button
indicator will turn off. However, even if the compressor is bypassed, the signal will pass
through the input/output transformer and amp circuits.
2 INPUT meter
Indicates the input signal level.
One meter appears in DUAL mode, and two meters appear in STEREO mode.
3 FB button
Switches the gain reduction method between FF (Feed-Forward) circuit and FB (Feed-
Back) circuit. The button will light when FB circuit is selected.
The FF circuit is used in most contemporary compressors. This type is useful when you
want to apply consistent compression while maintaining a consistent tonal color.
The FB circuit is used in vintage compressors. This type is suitable when you want to
apply a smooth compression while adding a tonal character that is characteristic of such
devices.
4 GAIN REDUCTION meter
Indicates the amount of gain reduction.
5 THRESHOLD knob
Adjusts the threshold at which compression starts to be applied.
6 RATIO knob
Adjusts the compression ratio. If you rotate the knob fully clockwise, the unit will operate
as a limiter.
7 ATTACK knob
Adjusts the compressor’s attack time.
8 RELEASE knob
Adjusts the compressor’s release time.
9 GAIN knob
Adjusts the output gain.
Portico 5045
This is a processor that accurately models the Portico 5045 Primary Source Enhancer made
by Rupert Neve Designs. Operation is extremely easy, allowing you to suppress background
noise that enters the mic while increasing clarity, enhancing the primary source and also
improving the feedback margin. It is suitable not only for a hand-held mic but also for a lavalier
mic or headset mic, and can be used in a variety of situations including event PA, concerts,
or broadcast. This processor is also equipped with the audio transformer and discrete amp
circuit that are the signature of the Portico series, so that simply passing the signal through it
will increase the luster and depth of the sound.
1 PROCESS ENGAGE button
Turns the enhancement circuit on/off.
2 RMS/PEAK button
Selects the operation mode for the level detector. You can select RMS mode or PEAK
mode.
