Manley SLAM! Mastering Version
The Manley SLAM! Mastering Version is a stereo valve limiter designed for mastering applications.
The Manley SLAM! Mastering Version is actually two limiters in one; one Electro-Optical circuit (ELOP) and a really fast FET-base brick-wall limiter both design to provide the flavour of some of the most sought-after limiters keeping their ease of use ethos that have made those compressors highly desirable on vocals.
First is the Electro-Optical (ELOP) limiter which is a firm favourite for tracking vocals. It features a side-chain high pass filter to avoid unwanted rumble to affect the gain reduction. Like many other electro-optical limiters, the SLAM! Mastering edition features 5 ratio settings: 10:1, 5:1, 3:1, 2:1 and a unique Auto HF which starts at 1.5:1 and gradually increases to 10:1 for high frequencies. This works effectively as a De-Esser which can work wonders with the ELOP Side Chain toggle set at 200Hz.
Following the ELOP is Manley’s implementation of the FET Limiter. Extremely versatile, the FET limiter can yield great results from clean and predictable to grungy and distorted. This quality is what made some FET limiters so desirable. By controlling the Release, you can add different colour and behaviour. A CLIP setting lets you add even more crunch and distortion. The attack control works in a very unique way adding some of the characteristics of attack on compressors while retaining a zero-overshoot tolerance found in brick-wall limiters. In the SLAM! Mastering Version, Manley has included some extremely useful features such as 50%, LP Lim, Both and Clip modes. The 50% mode mixes an uncompressed signal with the limited signal giving you all the flavour of the FET limiter but with a much cleaner sound due to the mix. LP Lim focus its limiting in the low frequencies and reduces the gain reduction resulting in a brighter and more present signal. “CLIP” introduces a fixed threshold clipping circuit at around -2dBFS preventing from output overs which would clip in a less musical way once converted in the digital domain.
Metering is taken care of by two real VU metres providing visual feedback on input levels, final output levels and the ELOP gain reduction. The VU Meter features a three-way toggle switch to accommodate for the different levels 0, -3dB and -6dB. FET Gain reduction metering is included in the form of super accurate multi-colour LED Ladder peak meters.
