The dbx 162SL is a professional two-channel compressor/limiter, representing a notable evolution in the renowned 160 series that has been a staple in recording and broadcast studios for decades. This unit builds upon its predecessors' legacy of providing robust, musical dynamics control with enhanced features and refined circuitry. It utilizes dbx's proprietary OverEasy® compression characteristic, which introduces gain reduction in a gradual, smooth manner to avoid the abrupt "pumping" or "breathing" artifacts often associated with faster, hard-knee compressors. This makes it particularly valued for its ability to transparently manage levels on a wide range of source material, from vocals and bass guitars to stereo buses, adding punch and consistency without overly coloring the sound.

Each channel of the 162SL operates independently, featuring comprehensive control over the dynamics processing parameters. Users can adjust the threshold, ratio, attack, and release times with precision, allowing for everything from subtle level evening to assertive peak limiting. The inclusion of both a dedicated compressor section and a separate limiter function with its own threshold control provides exceptional flexibility; the compressor can be used for gain smoothing while the limiter acts as a final safety net against transient peaks. A distinctive feature is the Stereo Link mode, which, when engaged, perfectly synchronizes the gain reduction across both channels to maintain a stable and coherent stereo image when processing a linked stereo signal.

Housed in a single rack-space unit, the 162SL is designed for reliability and intuitive operation in fast-paced professional environments. Its front panel layout is clear and logical, featuring large VU meters that switch to display either input level, output level, or gain reduction, providing immediate visual feedback. The robust construction and high-quality internal components ensure consistent performance and longevity. The dbx 162SL is renowned for its "glue-like" effect on mixes and its ability to deliver professional-grade dynamics processing with a musical, predictable, and often described as "forgiving" character, cementing its place as a classic tool for both tracking and mixdown.
