McDSP AE600 Active EQ v7 — Free Download

Purpose and Core Design

The AE600 Active EQ is McDSP’s latest take on active equalization, designed as a versatile tool for mixing, mastering, and sound design. At its heart, the AE600 treats every band—fixed and active—with its own gain, frequency, Q, and mode controls, allowing fully independent operation. This enables users to blend traditional static EQ curves with dynamic, level-triggered response in a single instance.

The plugin includes a wide array of EQ mode options, from parametric and proportional Q to vintage-styled and Baxandall shelving curves, plus high and low pass filters. All bands overlap completely and can be driven by the input signal or selected side chain inputs, making the AE600 adaptable to complex source material.

Key Capabilities

A defining feature is the active EQ response, shaped by each band’s threshold, attack, and release, along with a unique ratio control that refines sensitivity to input level. This lets the user articulate exactly how the active equalization reaches its maximum effect, offering depth beyond typical dynamic EQs.

The active bands can be managed directly from the response plot or via text readouts, and peak signal displays for each band help fine-tune threshold settings. Additional tools include input and output controls, per-band bypass, linking between bands, and key signal monitoring, all contributing to speed and precision during setup.

Workflow and Operation

For typical mixing tasks, the AE600 fits well on vocals, drums, or instruments where frequency balance shifts with playing dynamics. Users can set a fixed band for overall tone shaping, then add active bands to control specific resonances or sibilance that only appear at certain levels. Using side chain inputs lets the EQ respond to other sources, like ducking a frequency range against a competing instrument.

Interactive control via the response plot streamlines adjustments, and the peak readouts reduce guesswork when dialing in thresholds. The linking feature allows coordinated adjustments across bands, and bypass toggles enable quick A/B comparisons. Overall, the workflow encourages experimentation with mode combinations to match the character of the material.

Practical Applications

In mastering, the AE600 can gently tame harsh highs or low-end build-ups only when they exceed a set level, preserving the natural dynamics otherwise. For post-production, it is useful for dialogue cleaning without obvious pumping, thanks to the precise threshold and ratio controls. The side chain capability also supports creative effects like automatic frequency-based sidechaining.

Because all bands overlap, there is flexibility to stack multiple active bands for more complex dynamic filtering, and the low-latency algorithm makes it viable for live or tracking sessions where delay is undesirable. The vintage-styled modes offer color while the standard modes stay transparent, so the AE600 can serve both corrective and creative duties.
