SSL 4K B — Free Download

Authentic Channel Strip Emulation

The SSL 4K B plug-in is a painstaking emulation of the SL 4000 B channel strip, the console behind the Stone Room at London’s Townhouse Studios. It recreates the rich non-linear analogue character that shaped iconic records from the late seventies and early eighties. The plug-in includes a mic preamp based on the Jensen JE-115K-E transformer, which adds desirable harmonics when driven.

This preamp section is auto gain-compensated, so you can dial in saturation without drastically altering your levels. The EQ circuit is a precursor to the later ‘brown knob’ EQ and features constant bandwidth parametric mid-bands, ideal for shaping drums and bass with musicality. The overall design captures the console’s distinctive tone and punch, making it a versatile tool for adding character to individual tracks.

Dynamics and Unique De-ess Mode

The channel dynamics module is based on the legendary SSL Bus Compressor, featuring peak detection and a sidechain VCA in a feedback loop. This design provides punchy, glue-like compression that works exceptionally well on drums, bass, and full mixes. A distinctive ‘ds’ mode repurposes the compressor for broadband de-essing, triggering on sibilance just like the original hardware.

This makes the 4K B particularly useful for controlling harsh vocal recordings without dulling the overall tone. The modelled dbx 202 ‘black can’ VCA fader introduces subtle saturation at the output stage. You can drive the fader to add harmonics, then use the output trim to restore optimal levels. This offers a creative way to add warmth and analog color to any source.

HQ Mode and SSL 360° Integration

The High Quality (HQ) mode enables intelligent oversampling to more closely approximate a continuous analogue signal. This minimizes aliasing and preserves the high-frequency detail, especially when driving the preamp or fader hard. It is recommended for final mixing stages, while standard mode may suffice for tracking or rough mixes.

The 4K B integrates seamlessly with the SSL 360° Plug-in Mixer ecosystem, allowing you to mix and match it with Channel Strip 2 on virtual SSL console channels. This provides a unified control surface with compatibility for SSL UF8 and UC1 hardware controllers, offering tactile, hands-on control over the plug-in’s parameters. This integration streamlines workflow for engineers familiar with SSL console ergonomics.

Workflow and Practical Applications

In a typical workflow, insert the 4K B on a channel in your DAW. Start by adjusting the input gain to drive the preamp for harmonic saturation, using the gain-compensated output to balance levels. Use the EQ to sculpt frequencies, especially the mid-bands for drums and bass. The compressor can be set to glue a drum bus or control dynamics on a vocal track.

The de-ess mode is a quick solution for sibilance problems. For aggressive saturation, push the fader and compensate with the output trim. This plug-in shines on rock, pop, and electronic music where analog character is desired. It is best used as an insert on individual tracks or buses, and its SSL 360° integration makes it a staple for those using SSL hardware controllers.
