Relab Development Maselec Bundle - ESD

The Relab Development Maselec Bundle brings together two officially endorsed emulations of legendary mastering hardware in one powerful package. Combining the MEA-2 Precision Stereo EQ with the MLA-4 Triband Compressor/Expander, it delivers the tone, control and reliability of a world-class mastering chain directly inside your DAW, with added digital workflow enhancements that go beyond the original units.

Developed in close collaboration with designer Leif Mases and fully approved by Maselec, these plug-ins faithfully capture the behaviour and musicality of the original hardware. At the same time, they introduce modern conveniences such as detailed monitoring, mid/side processing on every band, and flexible user interfaces that make it easier to work quickly and accurately on demanding mastering and mixing sessions.

Mastering Grade EQ for Natural, Musical Control

The MEA-2 Precision Stereo EQ is designed for subtle, transparent shaping where every half dB counts. Its hand-tuned asymmetrical Q curves allow you to sculpt frequencies in a way that feels instinctive and musical, avoiding the harshness or sterility that can creep in with more clinical designs. Wide shelving bands help you gently balance low and high frequencies across the whole mix, keeping everything clear, open and controlled without drawing attention to the processing itself.

Triband Dynamics that Preserve Tonal Balance

The MLA-4 Triband Compressor/Expander gives you detailed dynamic control across low, mid and high bands while Auto Spectral Balance works in the background to maintain the natural tone of your mix. You can tighten bass, enhance midrange presence or open up the top end without the usual side effects of multiband processing. Each band can compress or expand independently, so you can restore punch to overcompressed material, tame problem areas or add life and movement where needed.

Advanced Monitoring and Workflow Enhancements

Both plug-ins are designed to help you make decisions with confidence rather than guesswork. The MLA-4 offers per-band solo, gain reduction metering and channel-specific listening, so you always know exactly what your processing is doing. The MEA-2 provides mid/side control on every band along with solo isolation, letting you zoom in on specific frequencies or stereo regions quickly. Together, they streamline your workflow, allowing you to move through complex sessions efficiently while staying focused on the sound.

Officially Endorsed Authenticity with Modern Flexibility

As the only Maselec emulations officially endorsed by the original hardware designer, these plug-ins deliver the trusted mastering sound heard on countless professional releases. At the same time, they embrace the advantages of software with resizable interfaces, intelligent sidechain linking, per-band harmonic shaping and detailed stereo controls. Whether you are mastering full projects or refining critical mix busses, the Relab Maselec Bundle gives you a refined, modern toolkit built on proven analogue heritage.
