With a big, bold preamp and the flexibility of variable Silk/Texture, Rupert Neve designed the Rupert Neve Designs Portico 511 500-Series Mic Pre Module to combine classic sonics with 500-series value. Incorporating the 517’s powerful preamp, the 5012’s universally useful sweepable high pass filter, and the transformer-saturating power of a variable silk circuit derived from our flagship Portico II Channel, the 511 is a Rupert Neve-designed micpre for the masses.
Input signals may be derived from Mic or Line sources (make sure 48V is off for line sources!). The input has a 10K â„¦ 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.
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. With the 511, the Texture control allows these techniques to be pushed further than previous designs, adding about 10 times the desirable THD of the original silk control at its maximum setting.
With that said, we have taken great care to ensure that the musical integrity of source material itself will not be compromised by these harmonic controls (these are not to be confused with controls from other manufactures that may “incinerate”, “demolish” or “destroy” source material), and we believe they can be confidently utilized to fit the personality of any song, instrument or engineer.
The main features of the Rupert Neve Designs Portico 511 500-Series Mic Pre Module include:
- 12-way stepped gain input control
- +/-6db trim control
