The SL 4000 B console, introduced in 1976, gained legendary status through its use in London's Townhouse Studios 'Stone Room'. This iconic mixing desk shaped the sound of numerous classic records, including Phil Collins' 'In the Air Tonight', The Buggles' 'Video Killed the Radio Star', and Peter Gabriel's 'Intruder'. Its distinctive sonic character and dynamic response have made it a sought-after reference for audio professionals aiming to capture vintage warmth and punch.

This plugin is a faithful emulation of the SL 4000 B channel strip, delivering the rich, non-linear analogue tone that defined the original hardware. Seamlessly integrated with the SSL 360° Plug-in Mixer ecosystem, it offers a powerful preamp section that adds harmonics and drive while maintaining level integrity through automatic gain compensation. This makes it easy to enhance tracks with authentic coloration and a dynamic edge without compromising signal quality.

The plugin features the original 4000-series EQ circuit alongside channel dynamics modeled on the renowned SSL Bus Compressor. It also includes a de-esser mode and a modeled dbx 202 VCA fader, providing comprehensive tonal shaping and control. Enhanced processing is available via an HQ mode with oversampling, and full support for native Apple silicon M1/ARM ensures smooth performance across modern systems. This combination makes it an essential tool for producers seeking to inject classic SSL character into their mixes.
