McDSP AE600 Active EQ Native v7 — Free Download

Purpose and Core Design

The AE600 Active EQ Native v7 by McDSP represents an advanced approach to equalization, combining traditional fixed EQ bands with dynamic, active bands that respond to input or sidechain signals. Its core purpose is to offer precise tonal shaping with the added flexibility of level-dependent filtering, making it a versatile tool for music production, post-production, and sound design.

Each of the six fully overlapping bands can be configured as either fixed or active, with independent control over gain, frequency, Q, and mode. This design allows users to mix static EQ curves with dynamic processing within a single plugin, enabling complex corrections and creative effects. The active bands use threshold, attack, and release settings, plus a unique ratio control that scales input sensitivity, distinguishing the AE600 from simpler dynamic EQs.

Key Capabilities and Modes

The plugin includes a variety of EQ modes to suit different material: parametric, proportional Q, 5x Q parametric, Baxandall shelving, vintage-styled, X-style shelving, Baxandall with filtering, and high/low pass filters. Each band can have its own mode, allowing hybrid curves that combine, for example, a vintage-style low shelf with a precise proportional Q mid band.

Active EQ response is visualized on the response plot, and bands can be adjusted directly on the graph or via numerical readouts. Peak signal indicators for each active band help set thresholds quickly. Input and output controls, per-band bypass, linking of band controls, and key signal monitoring are included. Sidechain inputs are supported, enabling frequency-selective dynamic processing triggered by external audio.

Workflow and Control

The AE600’s workflow centers on flexibility: users can set a static EQ curve for overall tone, then engage active bands to automatically reduce or boost frequencies when signal levels cross a threshold. The ratio control lets engineers decide how aggressively the active EQ responds to level changes, offering subtle or pronounced dynamic EQ effects.

Band controls can be linked, simplifying adjustments across multiple bands simultaneously. The response plot serves as an intuitive visual interface for both fixed and active bands, with text readouts providing precise numeric control. A key signal monitoring function aids in auditioning what triggers the active EQ, useful for de-essing, bass ducking, or handling resonant peaks in vocals or instruments.

Practical Applications

Typical uses include controlling sibilance in vocals with a narrow active band, ducking muddy low-mids on bass in a mix, or gently automating a high shelf to brighten a track as it gets louder. The sidechain capability allows creative frequency-dependent compression-like effects, such as fading out a synth pad when a kick drum plays, by keying an active band to the drum’s signal.

In mastering, the AE600 can apply subtle dynamic EQ to tame harsh frequencies only when they appear, preserving transparency. Its ultra-low latency and double precision processing make it suitable for tracking and live applications as well. Users should note that a companion AE400 may offer fewer bands, but the AE600 standalone provides comprehensive control for detailed equalization tasks.
