The ACM520X1 is a console bus compressor plugin inspired by a renowned analogue compressor known for its ability to add cohesion to a mix. It offers a range of compression settings from subtle 2:1 ratios, ideal for gently gluing elements together, to more pronounced punch at higher ratios. A key feature is its switchable side-chain high-pass filter, which helps manage bass-heavy content without causing over compression, preserving the natural dynamics of the performance.

Designed as a virtual 500-series module, the ACM520X1 combines a modern, user-friendly interface with the sonic characteristics of classic analogue gear. It features soft-knee compression at lower ratios, delivering smooth and musical dynamic control. At higher levels, the plugin introduces a subtle analogue-style overdrive that adds warmth and character, enhancing the overall tonal quality of the mix.

This plugin supports both mono and stereo processing, offering professional-grade console bus compression while maintaining efficient CPU usage. Its controls are smooth and free from artifacts when adjusted, and the physically modeled rotary controls provide an authentic tactile experience. Compatible with VST, VST3, AAX, and CLAP formats on Windows and Linux platforms, the ACM520X1 is easy to install and intuitive to use, making it a reliable choice for mixing engineers seeking classic console compression.
