Rupert Neve Designs 5033-H Five Band EQ (horizontal)

Rupert Neve Designs 5033 Five Band EQ

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.

The 5033 features Rupert’s custom input and output transformer designs, five bands of EQ based on his traditional curves, +/-12dB input level adjustment, and five filter bypasses. It comes available in either horizontal or vertical formats, for rack-mounting or inclusion in a 5088 console.

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 engaged but not boosted or attenuated.

“I'm not sure what magic is inside the 5033, but everything I send through it immediately sounds good...All said, I think the 5033 is a fantastic EQ.”

Low Frequency (LF) Shelving Filter

Continuously variable from 30Hz to 300Hz, 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, proving to be an indispensable asset in the signal chain.
High Frequency (HF) Shelving Filter

Continuously variable from 2.5kHz to 25kHz, giving this section of the EQ a valuable range of operation. Whether you want to really bring out the presence and breath of your vocals or simply add some "air" to your overall mix, the HF shelving filter will give you that bit of sparkle you’re looking for.
Mid Range Parametric Filters

To cover the crucial mid-range, the 5033 comes with three bands of parametric EQ, each separately engaged and having a true "flat" response when each section is engaged but not boosted or attenuated. Each section is capable of boosting or attenuating up to 12dB, and includes a variable "Q" control. "Q" controls range from 0.6 to 3, allowing you to vary the bandwidth of the attenuation or boost – whether a broad range of frequencies to gently give a sonic section a slight boost or dip or using the filter with a very narrow range of frequencies, acting like an "audio chisel" to precisely hone in on offending frequencies.

The Low Mid Frequency (LMF) section is variable from 50Hz to 400Hz. 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.
