Portico 5043
Portico 5043, like Portico 5033, is a processor that emulates RNDs 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 compression thoroughly 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 color that is characteristic to the device.
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. Fully rotate the knob clockwise to switch to the 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.
