Portico™ 5033 Five Band EQ and high performance line driver is a new equalizer with the performance, features and musicality expected from Rupert Neve, the designer. The 5033 features Mr. Rupert Neve’s custom input and output transformer designs, five bands of EQ based on his traditional curves, -/+12dB input level adjustment, five filter bypasses and comes available in either horizontal or vertical formats.

Low Frequency and High Frequency Shelving Filters

For extremes 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 12 db, providing steeply rising or falling curve shapes in accordance with Mr. Neve’s traditional filter desings. When these curves are boosted or cut aggressively, 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 less aggressively, 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/oct. and give a true “Flat” response when this section is engaged but not boosted or attenuated.

The Low Frequency (LF) shelving filter is continuously variable from 30Hz to 300 Hz, allowing for a wide range of applications, from filtering out low rumbles caused by air conditioning units to taming an instrument with too much low end or even adding a little bit of “oomph” to a thin mix.

The High Frequency (HF) shelving filter is continuously variable from 2.5 kHz to 25 kHz. Whether you want to really bring out the presence and breath to a vocal add some “air” to overall mix, or tame high frequency harshness and noise.

Mid Range Parametric Filters

To cover the mid-range, the 5033 comes with three bands of fully parametric EQ for the meticulous sculpting of audio signals. Each section is separately engaged and has a true “flat” response when engaged but not boosted or attenuated. The three mid-band filters are also capable of +/- 12 dB of gain and have an additional fully variable “Q” control from a broad 0.7 and narrow 5 that allow for ultra-hyper critical adjustments to the filter bandwidth.

The Low Mid Frequency (LMF) Section is variable from 50 Hz to 400 Hz. The Mid Frequency (MF) Section is variable from 330 Hz to 2.5 kHz. The High Mid Frequency (HMF) Section is variable from 2 kHz to 16 kHz. Each section has been carefully designed to overlap neighboring ranges, allowing for a very fine range of possible adjustments.

High Performance Line Driver

The 5033 also can serve as a high performance, transformer coupled line driver with continuously variable +/-12dB trim for optimal gain staging and level matching between processed and unprocessed signals. Like many of Mr. Rupert Neve’s classic modules, the line driving circuit adds sweetness, warmth and presence that can greatly benefit signals that are somewhat brittle and lifeless.

Stereo Operation

The 5033 is also extremely well suited for stereo buss work. Simply rack two 5033's with a 5221 RM and set the controls to match.
