McDSP AE600 Active EQ HD v7 is a dynamic equalizer with six overlapping bands, unique active EQ modes, and an ultra-low latency algorithm for precise audio production.

Purpose
The AE600 Active EQ HD v7 by McDSP is a next-generation equalizer designed for audio production. It combines traditional fixed EQ with dynamic active EQ bands, offering a flexible tool for shaping sound. Its ultra-low latency algorithm makes it suitable for tracking and mixing.
This plugin gives users independent control over fixed and active EQ bands, allowing precise adjustments. With six fully overlapping bands, each equipped with its own gain, frequency, Q, and mode controls, the AE600 adapts to various audio sources. It is part of McDSP’s HD v7 plugin line.
Key Capabilities
The AE600 features a wide range of EQ modes, including parametric, proportional Q, 5x Q, Baxandall shelving, vintage styled, X-style shelving, and high/low-pass filters. These modes can be applied per band, giving users extensive tonal control. All bands overlap completely, enabling complex EQ curves.
A standout feature is the unique ratio control, which adjusts input signal sensitivity for the active EQ response. This, along with threshold, attack, and release settings per band, allows dynamic equalization. Side chain inputs can trigger the active EQ, and the response plot provides intuitive control.
Workflow
To use the AE600, you start by selecting an EQ mode for each band and adjusting its frequency, gain, and Q. For active bands, set the threshold, attack, and release to determine how the EQ reacts to the signal. The ratio control further shapes the response based on input level.
The response plot and text readouts allow precise adjustment of active EQ parameters. Peak signal readouts below band dynamics plots help set thresholds quickly. Input/output controls, individual band bypass, and band linking streamline the mixing process. Key signal monitoring aids in aligning the EQ with your source.
Applications
The AE600 is versatile for music production, post-production, and sound design. Use it to add dynamic presence to vocals, control resonant frequencies in instruments, or apply subtle tonal shaping during tracking. Its side chain support enables frequency-dependent ducking or enhancement.
The ultra-low latency makes it ideal for live tracking or monitoring. With double precision processing, it maintains audio integrity even in complex mixes. Whether for corrective EQ or creative sound sculpting, the AE600 offers a robust solution for engineers seeking dynamic control.
