Rupert Neve Designs 551 - 500-Series Inductor EQ

  • 3 Bands of EQ inspired by Mr. Rupert Neve's classic designs
  • Low band - 4 selectable frequencies, +/- 15 dB
  • Mid band - 6 selectable frequencies, +/- 15 dB
  • High band - 2 selectable frequencies, +/- 15 dB
  • 12 dB/octave HPF fixed at 80 Hz
  • Transformer balanced IO with custom Neve transformers
  • 500-Series format

The 3-band, custom-tapped inductor EQ on the 551 was inspired by RNDs favorite portions of Ruperts vintage EQ designs. The low frequency band is designed to produce a creamy, resonant bass response however, unlike the vintage modules that inspired it, the LF band on the 551 can be used as either a shelf or a peak filter, adding punch, dimension, and control to your low end. The 551s inductor midrange band is ideal for sweetening vocals and instruments while bringing them forward in a mix, and its proportional Q response makes it well-suited for minimizing problematic frequencies. The high frequency band is a hybrid vintage / modern design, blending inductor circuitry with capacitor-based topologies to achieve vintage tones with enhanced control. The High Pass filter is a 12dB/octave design with a fixed 80Hz frequency, and can be used in tandem with the low frequency EQ to add low-end presence without clouding the source material.

As Rupert originally intended with his most prized classic designs, each EQ section uses low-feedback, class-A discrete electronics to prevent low-level artifacts and harshness from detracting from the tonal shaping. However, this new circuit is a decidedly modern design with updated techniques and components that were simply not available 35 years ago, and should not be considered a clone.

Both the high and low band can be switched from shelf to peak curves and offer 15 dB of boost or cut. The high band can be switched from 8 kHz to 16 kHz, and the low band can be selected at 35 Hz, 60 Hz, 100 Hz or 220 Hz. The inductor based Mid Band offers 6 center frequencies; 200 Hz, 350 Hz, 700 Hz, 1.5 kHz, 3 kHz and 6 kHz. The Mid Band also has a Mid Hi Q switch to narrow the bandwidth (increase the Q) of the filter.
