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.
