The Rupert Neve Designs Portico II Channel Module is a 2U channel strip consisting of fully featured microphone preamplifier, a 4-band EQ, a compressor-limiter, and offers texture control and level metering. This module also includes a bevy of new features such as Variable Silk / Silk+ Texture control, a fully tunable De-Esser, multiple VCA filtering and detection options, a transient-optimized swept HPF and parallel compression blending. With its simple yet powerful topologies and extensive feature set, every element of the Portico II Channel Module is geared towards empowering recording artists to realize their visions.

For recording and mixing engineers, the greatest challenge will always be to capture and transform disparate 2D elements into an engrossing 3D vision that elicits the same raw emotions and compelling vibrance as the live performance. In designing the Portico II Channel Strip, every possible attention has been paid towards not only producing accurate, sweet-sounding audio topologies but also enabling engineers to boldly shape or fine tune tracks to the limit of their imaginations.

The module has a full 19” rack width and is a 3.5” (2U) unit with standard rack mounting ears. Its construction incorporates a heavy and robust steel shell that provides total magnetic screening and high mechanical stability.

The front panel of this unit is machined from a solid 0.2” aluminum plate with a steel sub panel behind it. The unit uses +36 and -36V power supply rails. The signal path has many similar circuits. Amplification is handled with discrete (individual transistors) operational amplifiers (gain blocks). These discrete circuits are in the tradition of Rupert’s original circuits used in recording consoles from the 70’s and in many ways sound similar; however, there are refinements in noise, slew rate, dynamic range, and particularly, avoidance of unpleasant high frequency distortion artifacts. These gain stages are married to custom-designed input and output transformers.

While combining the three modules into the Portico II Channel Module, a few more features were also added in the internal routing like the HPF to Side-Chain, and the EQ / Compressor order selection. In this case, the sum is obviously greater than the individual parts; you get 3 powerful and versatile boutique processors that have evolved into this channel module.

The Portico II unit has a high-quality, low noise switching power supply that is further filtered and shunt regulated for a quiet and reliable power source for audio circuits. The power supply is considered universal in the sense that it will accept 100 to 240VAC voltage and complies with standard mains voltages around the world.

Note:
Ensure correct mains voltage and correct fuse before connecting. Equipment must be earthed by a power cord (not included).

Input Section

Three Sources

Input signals may be derived from any of three sources: Microphone, Line, or DI. The microphone input has a 10 kΩ non-reactive input resistance that handles a full 26 dBu signal without the need for a pad

Gain Control

A primary gain control provides 66 dB of gain in 6 dB increments for easy recall with a ±6 dB trim for fine adjustment. A transient-optimized HPF continuously covering the range from 20 to 250 Hz is included. In addition, a 48V Phantom Power switch, Phase Inversion, Signal Present indicator, and mute switch are included

TLA Non-Reactive Design

Precludes the loading of microphones with limited driving capability and maintains a 2 dB noise figure over a wide range

DI

Inserting a plug into the DI input selects a 3 MΩ discrete FET DI circuit that includes the transformer-coupled pristine topography, which optimizes both microphone and DI inputs, allowing low impedance microphones and high impedance sources like electric guitars and basses to deliver their optimum performance

Gain and Trim Controls

Primary gain and trim controls are fully operational. A thru jack on the front panel that duplicates the unaffected source signal allows the use of an external amplifier if required. A line switch selects the independent line XLR non-reactive input circuit that includes the HPF and level trim controls

Texture

Harmonic Adjustments

Adjusts the actual amount of harmonic music content from the source material, in effect, providing multiple tonal options in one device

Texture Modes

The texture section features distinct modes, controlled by a potentiometer from barely audible to dramatic. The musical integrity of the source material itself will not be compromised by these harmonic controls. They can be confidently modified to fit the personality of any song, instrument, or engineer

Silk+ Mode

The Silk mode works by reducing negative feedback on the output transformer and adjusting the frequency response. The Silk+ mode pushes this technique still further, achieving a more harmonically rich sound

Continuously Variable Control

Continuously variable control for Silk and Silk+ modes allows the engineer to fine tune the harmonic ratio and tonality of the channel.

Equalizer

Topologies

The EQ topologies in the 4-Band Equalizer of the channel combine the sound of several classic designs, but are also capable of extremely fine surgical adjustments as well as dramatic boosts or cuts

Signal Processing Chain

By default, the EQ section follows the mic preamplifier and HPF, and precedes the compressor, but this sequence may be reversed by engaging the Post Comp switch

Low Shelf

The Low Shelf has an independent engage switch, Classic Peak/ Accelerated Shelf selection, with ±12dB level adjustment, and selectable turnover frequencies of 35, 60, 100, and 220 Hz with in / out and peak / shelf modes.

Parametric LMF and HMF

The Fully Parametric LMF and HMF bands have a joint engage switch, providing ±12 dB level adjustment, continuously variable Q from 0.7 to 5 and continuously variable frequency ranges from 70 to 1.4 kHz and 700 Hz to 14 kHz. In addition to its standard capabilities, the HMF band can also be used to precisely tune a new De-Esser circuit

De-Esser

The De-Esser can be varied from off to full effect, and uses the frequency and Q controls to tame harsh sibilance in vocals and instruments with an independent high-mid limiter. Even when the De-Esser is on, the EQ level may still be used.

High Shelf Controls

The High Frequency shelf has independent engage switch, Classic Peak/ Accelerated Shelf selection, ±12 dB level adjustment, and selectable turnover frequencies of 4.7, 6.8, 12, and 25 kHz. When two Portico II Channel Modules are used side by side, the EQ section can also excel at stereo material

Compressor

Feed-Forward / Feed-Back Modes

Provides flexible Feed-Forward / Feed-Back modes, either providing a transparent modern response (FF) or a smoother more musical vintage response (FB)

Controls

Along with FF/FB modes, there are also 1:1 to 40:1 ratio controls and threshold from -30 to +20 dBu, together with Attack from 20 to 75 ms (0.1 ms in Peak mode), Release from 100ms to 2.5s, and Makeup gain from 0 to 20 dB with a Stereo Link.

HPF to SC

Inserts the High Pass Filter into the side chain to deal with intense low frequencies that may skew the response of the VCA with certain songs and instruments.

Peak Switch

Alters the compressor's attack to react to transients with a roughly 0.1 ms response time. When peak is disengaged, the compressor responds to the RMS signal in conjunction with the attack and release settings

Mix Compressed and Dry Signal

Works by creating a parallel mix between the compressed and dry signals. By mixing the compressed and dry signals, it is possible to increase the volume of quieter elements in the source material (for instance, delicate snare brushing on a track with much louder hits), while maintaining a natural dynamic feel for the louder elements

Insert Send and Return

To further control the side chain, there is also an insert send and return that may be paired with an external EQ or other filters for additional manipulation. The return may also be used as a Key input for ducking one signal under another (for instance, a voice-over keying the compressor to duck a background music track)

Link Button

Allows you to connect one Portico II unit to another Portico II link jack and engaging the Link buttons, the compressor section may be used for stereo material

Front Panel

Line Input

Provides selectable +4 balanced input transformer-balanced line level input with ±6 dB trim control

EQ Master Switch

HF EQ

Provides ±15 dB gain selectable at 4.7, 6.8, 12, and 25 kHz, with in / out and peak / shelf modes.

FF/FB

Back Panel

Link

Joins multiple Portico compressors VCA signals
