Three Mixing Essentials in One Eurorack Module

Combining a stereo width processor, 2A-style optical compressor, and a 73-style EQ, the 4ms Leveling EQ Amplifier is a feature-laden, end-of-chain channel strip packed into a cohesive Eurorack module. Drawing on the classic simplicity of two tried-and-true mixing staples, the LEQA leverages predefined curves and frequency selections to ensure intuitive operation and eminently ear-grabbing results. You’ll revel in this module’s smooth, natural compression and warm, musical gain reduction, and the British-flavored EQ section is exactly what you need to clean up — and add excitement to — your mixes. Finally, the Width knob allows you to tighten your stereo image or expand mono sources. Able to tackle live performance, studio work, and creative sound design with equal aplomb, the Leveling EQ Amplifier is the perfect tool for subtle sweetening, extreme sonic sculpting, and gluing your patches together.

Experience the science of wide

The Leveling EQ Amplifier’s stereo width processor is among its most versatile assets, leveraging a novel implementation of the Haas effect to deliver expansive mono-to-stereo conversion. Whether you're tightening a wide stereo image into a focused, cohesive mix, summing to mono, or pushing a signal into larger-than-life super-stereo territory, this processor handles it all with ease. Best of all, the dedicated Width knob and Width CV jack give you precise, performance-ready control, whether you're dialing in a static setting in the studio or riding the effect live.

British-flavored tone-shaping power

The 73-style EQ has no shortage of devotees here at Sweetwater. In fact, our flagship Studio A houses a world-class large-format British console of the same storied lineage. The 4ms Leveling EQ Amplifier’s EQ channels that same timeless design philosophy, pairing a low shelf, midrange bell, and high shelf with an additional highpass filter with a selectable frequency. Each filter is voiced with tailored frequencies and generous boost and cut ranges, keeping the focus on musical results over technical fuss. Moreover, you’ll appreciate the LEQA’s flexible routing, which allows you to place the EQ pre- or post-compression, or you can bypass it entirely. You also get a global EQ Level knob that offers everything from subtle tone shaping to dramatic sonic transformation.

Smooth optical compression

There’s something magical about the 2A-style optical compressor. Its smooth, warm musicality, bolstered by program-dependent attack and release times, flatter everything you run through it. Based on the same legendary design, the Leveling EQ Amplifier’s compressor allows you to select between Comp 3:1 and Limit 10:1 ratios, with Amount and Gain knobs for dialing in your preferred amount of gain reduction and makeup gain. Additionally, you get a Mix knob for straightforward parallel compression and a vivid Gain Reduction meter for real-time visual feedback. And, of course, you can place the ratio selector in the Bypass position if you want to take the compressor out of your signal chain entirely.
