Manley Laboratories SLAM! Mastering Edition Limiter

Let the Manley SLAM! Mastering Edition take control of your dynamics and loudness. Two distinct and simultaneous limiters—the musical ELOP® and the fast FET "brick-wall" limiter—giving you a unique and versatile tool to shape your sound.

Two Limiters, One Purpose
The Manley SLAM! features a dual-stage limiting process for unparalleled dynamic control. The ELOP® optical limiter, renowned for its transparent and effortless gain reduction, provides a smooth, musical compression. This is followed by a lightning-fast FET limiter that can be used to catch the final peaks, creating incredible loudness without the harsh artifacts of digital clipping.

The Professional's Solution
The SLAM! is the perfect front-end. Its design delivers a rich, analog tone. It's the ideal tool to ensure your audio hits the digital converters with maximum sonic impact and integrity.

Built for Sonics, Engineered for Performance
The SLAM! is built to perform in the most demanding studios. Its outboard power supply keeps heat and magnetic fields away from the sensitive audio circuitry, ensuring a pristine signal path. With flexible I/O, a mini-patchbay for side-chain inserts, and attenuable VU meters that can be switched to prevent needle bending, it’s a robust and reliable tool for a lifetime of professional use.
