Description

Edit description

The Rupert Neve Designs 551 is a 500 Series Equalizer that effortlessly bridges the gap between vintage charm and modern versatility, making it an essential tool for any serious audio engineer. Drawing inspiration from Rupert Neve's legendary console EQs, the 551 offers three bands of meticulously crafted equalization, perfect for enhancing the depth and character of your mix. With custom-wound inductors and transformers, this EQ delivers the rich, resonant bass and sweet highs that have defined classic Neve sound for decades.

The 551's low-frequency band is a standout feature, allowing you to switch between shelf and peak modes to sculpt your bass with incredible precision. The midrange band, reminiscent of the iconic 1073, is ideal for pushing vocals and instruments forward, while its proportional-Q response effectively tackles problematic frequencies. Meanwhile, the hybrid high-frequency band combines vintage inductor circuitry with modern capacitor-based designs, offering nuanced control over your high-end tones.

Designed with low-feedback, Class A discrete electronics, the 551 ensures that your audio retains its purity, free from low-level artifacts or harshness. Whether you're sweetening vocals or refining instrument tracks, the Rupert Neve Designs 551 is a masterful blend of the old and the new, capturing the essence of Neve's timeless sound in a compact, user-friendly format.
