Rupert Neve Designs Portico 511 500-Series Preamp Module

The Portico 511 is a big, bold preamp with the flexibility of variable Silk/Texture, designed by Rupert Neve to combine classic sonics with 500-series value, nearly indistinguishable sonically from standard, full-sized Portico Series modules.

The Rupert Neve Designs' Portico 511 Preamp module incorporates the 517's powerful preamp, the 5012′s universally useful sweepable high pass filter and the powerful transformer saturation of a variable silk circuit derived from Neve's flagship Portico II Channel.

In Rupert's own words
“While creating functional 500 series modules is relatively simple, designing those modules to equal their non-500 series counterparts with the current, voltage and space restraints is quite challenging. In creating our own 500-Series Modules, we experimented with a number of different transformer and circuit designs to achieve the same presence and sweetness found in the Portico Series of modules. The result of these efforts is that outside of the slightly lowered headroom, our 500 series modules are nearly indistinguishable from standard Portico Series modules, and are perfectly suited for studios of the highest caliber.”

Input Section
Input signals may be derived from Mic or Line sources (make sure 48V is off for line sources!). The input has a 10K Ω non-reactive input resistance that handles a full 22dBu signal without the need for a pad. The pre-amp is a TLA non-reactive design that precludes the loading of microphones with limited driving capability. A primary gain control provides 66dB of gain in 6dB increments for easy recall, with a +/- 6dB trim for fine adjustment. For condenser microphones and powered DIs, there is +48V phantom power. A transient-optimized HPF continuously covering the range from 20-250Hz is included to tame rumble and proximity effect.

Texture Control
One of the key developments in the 511 is the Red Silk / Texture control from the Portico II Channel. Building on the “Silk” mode found in the Portico Series mic pre-amplifiers, Texture is designed to adjust the actual amount of harmonic music content from the source material, in effect, providing wide range of tonal options for the preamplifier. Like the original Portico Silk, the Silk Red / Texture works by reducing negative feedback on the output transformer and adjusting the frequency response to more closely resemble Mr. Rupert Neve’s vintage designs.

Low Noise, Low Distortion Operation
Much care was given in designing the 511 to produce as little noise and non-harmonic distortion as possible. Carefully implemented signal paths and Class A operation are a large part of the 511's sweet, whisper quiet performance.
