Rupert Neve Designs Portico 5033 5-Band Equalizer, Back

Add Neve sound to your studio rack with the Portico 5033 EQ/line driver! Rupert Neve transformers sweeten any source -- even when you bypass all 5 EQ bands.

Overview

The Portico 5033 Five Band EQ and high performance line driver is an equalizer for the Portico Series with the performance, features and musicality expected from Mr. Rupert Neve. Available here in a horizontal format for rack-mounting, the 5033 features Rupert's custom input and output transformer designs, five bands of EQ based on his traditional curves, +/- 12 dB input level adjustment, and five filter bypasses.

On the input and output of the 5033 lie custom-designed Rupert Neve transformers, a hallmark of his classic designs. The EQ section can be completely bypassed and the unit can be used as a very high quality line driver utilizing these transformers, which can help to add sonic "sweetness" to a source.

Low Frequency and High Frequency Shelving Filters

For opposite ends of the audio spectrum there are two separate shelving filters, which are both engaged or disengaged using the same LED pushbutton. Each shelving filter allows for a boost or cut of up to 12dB, providing steeply rising or falling curve shapes. When these curves are aggressively boosted or cut, they enable the second and even third harmonic to be varied in relation to their fundamental, allowing the natural sound of a musical instrument to be varied. When used more moderately, one can attenuate bands of frequencies above or below the "turnover" point to their desired levels. These sections each provide EQ curves that approximate to 6 dB/octave and give a true "Flat" response when this section is… read more engaged but not boosted or attenuated.
