Maselec MLA-4

The Maselec MLA-4 Triband Compressor/Expander is the first and only officially endorsed software recreation of the legendary hardware unit, developed in direct collaboration with Leif Mases.

Designed for mixing, mastering, and stem processing, the MLA-4 delivers natural, musical dynamic shaping with precise multiband control—now enhanced with modern workflow features only possible in software.

• Effortless dynamic shaping without tonal shifts – Auto Spectral Balance preserves mix integrity while managing dynamics.
• Analog warmth and depth, exactly where you want it – Per-Band THD Control lets you add harmonic coloration selectively.
• Confident, precise adjustments without guesswork – Advanced monitoring options provide per-band solo, left/right cuts, and independent channel monitoring for total control.

Whether refining a final master, shaping a mix bus, or restoring dynamics in a crushed stem, the MLA-4 delivers the depth and musicality of a revered analog mastering tool—meticulously recreated in plug-in form.

Features:

• Compress and expand independently or simultaneously for next-level dynamics control
• Up to 6:1 compression ratio with expansion down to 1:2 per band
• Per-band controls for Threshold, Ratio, Attack, and Release
• 5-mode sidechain linking system with full linking, independent band, and in-between modes
• Auto Spectral Balance with independent gain compensation plus Auto Level for maintaining mix integrity
• Per-band THD control lets you add harmonic coloration where you want it
• Advanced monitoring options include per-band solo, left/right cuts, and independent channel monitoring
