Precision Dynamics Without Compromise: Introducing the Relab Maselec MLA-4 Plugin

At Koala Audio, we're always excited to bring groundbreaking tools to the Australian audio community. As authorised resellers for Relab Development, we're thrilled to announce the arrival of a truly special processor: the Maselec MLA-4 Triband Compressor/Expander Plugin.

This isn't just another multiband dynamics plugin. Developed in direct collaboration with the legendary designer Leif Mases himself, this is the first and only officially endorsed software recreation of the iconic Maselec MLA-4 hardware unit – a staple in high-end mastering houses worldwide. Now, its unparalleled control, transparency, and musicality are available directly within your DAW.

Rethinking Multiband Dynamics for Flawless Control

Traditional multiband processors often come with compromises – phase distortion, transient smearing, and a noticeable "split" feeling in the audio spectrum. The Maselec philosophy, embodied in the MLA-4, was designed to overcome these challenges.

The MLA-4 offers a unique approach, allowing for surgical yet incredibly musical dynamic shaping. Its ability to apply compression and expansion simultaneously within each band, combined with adaptive sidechain linking and precision crossover filters, lets you:

  • Tighten low-end weight without losing punch.
  • Enhance vocal articulation and presence naturally.
  • Control harshness or sibilance transparently.
  • Restore dynamics and transients lost during processing.

Crucially, it achieves this without disrupting the overall integrity and tonal balance of your mix or master.

Leif Mases, Founder of Maselec, explains the magic:

"The MLA-4’s unique approach to compression and expansion is what makes it special. Unlike traditional multiband compressors, it doesn’t feel like the music is being divided into separate frequency zones - it remains a cohesive, natural- sounding mix. And with this plug-in, not only have we faithfully captured the precision and flexibility of the original hardware, but we’ve also expanded its functionality, making it even more powerful in a modern digital workflow.”

Key Features & Benefits for the Discerning Engineer:

  • Simultaneous Compression & Expansion: Naturally shape dynamics per band, controlling energy without unwanted artifacts.
  • Unique Sidechain Linking: Intelligently link band interactions for fluid, musical dynamic adjustments that maintain cohesion.
  • Mastering-Grade Crossovers: Transparent filtering minimises phase distortion and spectral imbalance, preserving the original source character.
  • Auto Spectral Balance: Prevents unwanted tonal shifts while managing dynamic movement across bands.
  • Per-Band THD Control: Add subtle (or not-so-subtle) harmonic warmth exactly where it benefits the audio.
  • Advanced Monitoring Tools: Solo bands, cut left/right channels, and use other tools to precisely hear how the MLA-4 is affecting your mix.

The original Maselec MLA-4 hardware is a significant investment, reflecting its status among the world's top mastering engineers (costing nearly AUD $15,000 / USD $10,000). Relab Development has now placed this exacting level of dynamic control within reach of every serious engineer and producer.
