This bundle from Pulsar Audio combines their Massive passive EQ with the Mu compressor, offering a powerful toolkit for mixing and mastering. Pulsar Massive emulates the renowned Manley Massive Passive EQ, a staple in mastering studios globally. It captures the unique sound of classic passive equalizers through a fully parallel topology, which creates tonal corrections that interact fluidly rather than cumulatively, setting it apart from typical digital equalizers. The plugin also replicates the original hardware’s passive equalization circuit with specially crafted inductors, resulting in a warm, organic character enriched by tube and transformer-driven gain stages.

The plugin features an intuitive interface with a visual curve editor that allows easy manipulation of the analog-shaped EQ curve, making precise tonal adjustments straightforward. Additional tools like Drive control add musical analog saturation, while Mid-Side processing enables separate treatment of mono and stereo elements for greater mixing flexibility. Other thoughtful features include auto-gain compensation to maintain consistent output levels, selectable oversampling for enhanced audio fidelity, and transformer options that range from authentic hardware emulation to warmer, colored modes. Real-time metering and spectrum analysis support detailed monitoring, all within a responsive, resizable GUI.

Pulsar Mu is a faithful reproduction of a legendary variable-bias tube compressor, designed to provide transparent compression with a hint of warmth. Its unique topology preservation technology captures the nuanced behavior of transformers and tubes, delivering smooth transient handling even under extreme compression. The compressor is ideal for adding cohesion and natural movement to mixes without compromising dynamics. It supports advanced features such as Mid-Side processing, external sidechain inputs, flexible sidechain EQ, and customizable visual feedback, all while maintaining efficient CPU usage. Together, Pulsar Massive and Mu form a comprehensive set for professional audio processing.
