McDSP 6020 Ultimate EQ v7 is a collection of ten equalizer modules, each modeled after classic and modern hardware, offering versatile tonal shaping for professional mixing.

Purpose and Collection Overview
The 6020 Ultimate EQ v7 is a versatile collection of ten distinct equalizer models, each designed to emulate the character of classic and modern hardware units. It covers a wide range of tonal options, from smooth tube-based warmth to aggressive solid-state precision, catering to various mixing styles and genres.
Each module is crafted to be intuitive yet sophisticated, suitable for both straightforward adjustments and detailed sound sculpting. The collection is built around McDSP’s extensive design experience, drawing inspiration from four decades of equalizer development to provide a comprehensive toolkit for audio professionals.
Key Modules and Their Characters
The collection includes the E670, a three-band EQ with gentle shelving and a mid-parametric, inspired by the Fairchild 664. The Moo-Q offers a warm, all-tube tone with high headroom, while the iQ is a two-band unit adept at adding low-end glow or high-end sheen.
The British-E amalgamates characteristics of classic Neve equalizers, and the EZ Q is a straightforward design with high-pass filtering and flexible shelves. The EQ ’76, based on the UREI 545, features four parametric bands with gain-dependent bandwidth, and the FRG EEE provides a modern channel-strip-like setup with two parametrics and shelves.
Workflow and Technical Features
In v7, all modules feature zero-latency algorithms and double-precision processing, ensuring high-fidelity performance. The user interfaces have been updated for high definition, and the plug-in is optimized for Apple Silicon and the latest Intel processors, making it suitable for modern production environments.
Each license now includes two activations, and the Classic Pack plug-ins have been updated with Phase buttons. This update enhances flexibility in mixing and mastering workflows, allowing for precise phase alignment and robust performance across different systems.
Practical Applications and Suitability
The 6020 Ultimate EQ is well-suited for a variety of mixing tasks. The E670 is ideal for subtle adjustments, while the E300/301 modules complement the Opto-C/L compressors for general-purpose use. The E357, designed to work with the D357 compressor, features steeper slopes with a unique character, and should be used with care.
Modules like the British-E and EZ Q are versatile enough for most mixing situations, from tracking to final mixdown. The collection’s range of tonal colors makes it a valuable asset for producers and engineers seeking specific hardware-inspired equalization without the need for external gear.
