Product Overview
McDSP's AE400 represents a distinct approach to dynamic equalization that distinguishes itself through architectural choices rather than mere feature accumulation. Unlike traditional parametric EQs or broadband dynamic processors, the AE400 layers fixed and active equalization across four fully overlapping bands, each with independent threshold, attack, release, and notably, a ratio control that modulates input sensitivity. This ratio parameter - uncommon in active EQ designs - provides nuanced articulation over how aggressively the processor responds to threshold crossings.
The active bands operate via sidechain detection, allowing the EQ to respond to either the main signal or an external key input. Combined with adjustable Q settings and selectable filter types per band, this architecture enables both surgical corrections and creative dynamic tonal shaping. The dual-layer approach of fixed plus active equalization means you're not choosing between static and dynamic correction; you're composing them.
The v7 upgrade brings optimization for current processor architectures and refreshed interface design while maintaining the core sonic character. Zero-latency processing and double-precision mathematics ensure transparent operation in tracking or mixing contexts. Real-time analyzers aid threshold calibration against material specifics.
This tool suits mixing engineers who value surgical control, post-production professionals managing challenging dialogue or music stems, and live sound operators requiring responsive, articulate EQ without audible artifacts. Among comparable processors, the AE400's ratio control and overlapping band architecture provide advantages for complex tonal problems where traditional dynamics or EQ prove insufficient.
