Rupert Neve Designs 551 Inductor EQ

Inspired by some of Rupert Neve’s vintage EQ designs, the 551 features a low frequency bands that produces a characteristically creamy and resonant bass response. However, the 551 implements a new feature here that sets it apart from its predecessors: its LF band operates as either a peak or shelf filter for added punch, dimension, and management of low-end frequencies. 

The unit’s midrange band is ideal for vocals and instruments, affording them that much coveted “extra space” that is frequently sought after in most audio mixes. Its high-frequency band is a vintage/modern hybrid with bedding inductor circuitry and capacitor-based topologies that afford characteristically vintage tones and improved control. The high-pass filter is 12dB/Oct and enjoys a fixed 80Hz frequency, meaning it can be used alongside the low frequency EQ for extra low-end impact.

551 Features

  • Inductor EQThe first 500-Series EQ designed by Rupert Neve. 551 EQ’s are built around custom-wound Inductors and are based on our favorite bands from Mr. Neve’s classic EQ modules
  • Low EQ+/- 15dB Shelf or Peak, selectable at 35 Hz, 60 Hz, 100 Hz or 220 Hz
  • Mid EQ+/- 15dB with 6 center frequencies; 200 Hz, 350 Hz, 700 Hz, 1.5 kHz, 3 kHz and 6 kHz, with High Peak switch to narrow the bandwidth (increase the Q) of the filter
  • High Shelf+/- 15dB Shelf or Peak selectable at 8 kHz or 16 kHz
  • HPF12 dB/octave high pass filter with a fixed 80 Hz frequency
  • Transformer I/OBuilt around Rupert’s custom transformers, designed especially for the 500-Series format
