Description
The Rupert Neve 551 Inductor EQ is the only equalizer for the 500 Series actually designed by Rupert Neve. Featuring 3 bands of EQ inspired by Mr. Neve’s most prized vintage designs, along with custom-wound inductors, transformers and class-A gain blocks, the 551 brings the thick, powerful lows and sweet highs of Rupert’s classics to the 500-Series format for the very first time.
Rupert Neve 551 EQ Features:
- Equalizer Bypassed. Noise: Measured at Main Output, un-weighted, 22Hz-22kHz, source impedance 40 Ohms balanced. Better than -102dBV
- Frequency Response: Main output, no load +/- 0.1dBu from 20Hz to 31.5kHz -1dB @ 120kHz
- Maximum Output Level: 23.25dBu
- Total Harmonic Distortion and Noise: @ 1kHz, +20dBu output level, no load. Better than 0.0025% @ 20Hz, +20dBu output level, no load. 0.13% Typical (2nd and 3rd harmonic)
- High Pass Filter: -2.7dB @ 80Hz Slope: 12dB/Octave
- Equalizer Engaged: Noise: Measured at Main Output, un-weighted, 22Hz-22kHz, source impedance 40 Ohms balanced. Better than -94dBV
- Frequency Response: Main output, no load +/- 0.25dBu from 20Hz to 45kHz -2dB @ 120kHz
- Maximum Output Level: 23dBu
- Total Harmonic Distortion and Noise: @ 1kHz, +20dBu output level, no load. Better than 0.009% @ 20Hz, +20dBu output level, no load. 0.13% Typical (2nd and 3rd harmonic)
- Power Requirements: 120mA on +16VDC. 110ma on -16VDC
- Not standalone — requires compatible 500 Series chassis (LunchBox R6 U & Rack R10 U)
