Product details
The Manley SLAM! (Stereo Limiter and Mic Pre) is a professional dual-channel analogue recording processor that combines high-voltage tube microphone preamplification with two distinct limiting stages per channel. Featuring Manley Iron® transformer-coupled inputs and outputs, an ELOP® electro-optical limiter, and a fast FET brick-wall limiter, it offers flexible dynamics control for vocal recording, transient management, and high-level studio signal processing.
Key Features
