The Rupert Neve Designs 5051 Shelford Inductor EQ and Compressor is a powerful 500 Series module that combines the timeless character of Neve's vintage inductor-based EQ with a modern, flexible compressor. Built to deliver the signature warmth and musicality associated with Rupert Neve, this module is perfect for mixing, tracking, and mastering applications in professional studio environments.

At the heart of the 5051 is its inductor-based EQ section, which provides three bands of highly musical tone shaping. The low and high bands are switchable between shelving and peak modes, allowing engineers to tailor their sound with precision. The mid band focuses on those critical mid frequencies that are essential for carving space and detail in a mix. Each band can be adjusted with precision, offering a wide range of tonal possibilities for various instruments and vocals.

The compressor section of the 5051 incorporates a VCA design with both RMS and peak detection modes, giving you detailed control over dynamics. Whether you're looking to gently control levels or apply more aggressive compression, this module excels. The compressor also features a blend control for easy parallel compression, enabling subtle dynamic control without losing the original dynamics and character of the source material.

One of the defining aspects of the 5051 is the transformer-coupled input and output stages. These transformers add harmonic richness and the signature Neve warmth, giving your mixes an unmistakable analog quality that is especially sought after in digital recording environments.

This module also includes vintage and modern compression modes, allowing users to switch between a classic Neve compressor sound and a cleaner, more transparent response, making it suitable for a wide range of applications. Whether you're mixing drums, vocals, guitars, or full mixes, the 5051 offers the tonal versatility and professional-grade sound engineers expect from Rupert Neve.

Designed exclusively for vertical 500 Series racks, the Rupert Neve Designs 5051 Shelford EQ and Compressor is a compact, space-saving solution for studios that want the legendary Neve sound in a modern, modular format. Ideal for high-end recording and production environments, this module offers unparalleled sonic detail, flexibility, and craftsmanship.
