SSL Revival 4000 Analogue Channel Strip

SSL Revival 4000 Channel Strip manufacturer description

The SSL Revival 4000 is a high-performance, all-analogue channel strip from Solid State Logic, delivering the unmistakable sound of the early 1980s SL 4000 Series consoles — a sound that set the industry standard and helped shape the music of iconic artists including Peter Gabriel, Phil Collins, Bryan Adams, Pink Floyd, Prince, U2, Metallica, and many more. Drawing on the revered circuitry of both the B and E Series consoles, the Revival 4000 offers the signature tone and sonic flexibility that form the very foundation of SSL’s legacy.

Originally launched in 1976, the SSL 4000 Series consoles revolutionised music production, setting a new industry benchmark that would go on to shape music history. It all began with the rare SL 4000 B console, installed at London’s Townhouse Studios. The 4000 B was used to create groundbreaking hits like Intruder by Peter Gabriel and the seminal gated-drum sensation In the Air Tonight by Phil Collins.
This set the tone for what would become the most influential mixing console of all time—the SL 4000 E. Introduced in 1979, the 4000 E became the heartbeat of legendary studios such as Abbey Road, Electric Lady, and The Hit Factory. It empowered engineers like Hugh Padgham (David Bowie, Paul McCartney, The Police), Chris and Tom Lord-Alge (James Brown, The Rolling Stones, Santana), and Andy Wallace (Prince, Bruce Springsteen, Nirvana) to craft their sound.

Introducing the Revival 4000—a signature analogue channel strip that encapsulates the sonic excellence and standout features of the legendary 4000 Series in a compact 1U format. Equipped with the classic E Series JT-115K-E Jensen transformer-balanced mic preamp, B Series De-Esser, the discrete Class A VCA Dynamics section from the E Series, and the iconic four-band parametric E Series EQ—complete with high-pass/low-pass filters and switchable Brown/Black knob EQ.

Offering flexible routing, a balanced insert point, and sidechain linking, the Revival 4000 is the foundational legacy channel strip, bringing SSL’s analogue heritage into any modern studio.

SSL Revival 4000 Channel Strip features

Classic Jensen Transformer Equipped SSL 4000 E Mic Preamp


Featuring a JT-115K-E Jensen transformer-balanced preamp, the Revival 4000 delivers richness and pristine clarity to your recordings. This circuit incorporates the very same Jensen component found in the original E Series channel strips.

4000 B-Series De-Esser 

Revival 4000’s De-Esser is lifted from the original compressor/limiter design of the iconic 4000 B console, delivering 10:1 ratio and a 7 kHz sidechain filter. This configuration enables broadband compression that’s precisely triggered by sibilance, making it ideal for taming harsh vocals, drums, or other aggressive sources. Its musicality is further elevated by a circuit design that mirrors that of the legendary SSL Bus Compressor, adding a familiar clarity and character to any signal.

Ultimate 4000 E Series Dynamics Section  


The iconic dynamics section that defined the sound of the 1980s—fully featured and faithfully recreated. The compressor/gate design stays true to the original E Series channel strip, meticulously replicating the circuitry and components that gave it its legendary character. It includes a true RMS sidechain detector and an all-discrete gain reduction stage, identical to the discrete Class A VCA chip used in the original console.

Flexible controls allow you to bypass the soft-knee curve, activate a fast attack mode, and choose between logarithmic or linear release curves. Together, these features offer a wide palette of tonal shaping options, capturing the distinctive voicings that helped craft countless classic records on a variety of E Series consoles.

Classic 4-Band SSL EQ


The celebrated 4-band parametric EQ that helped shape modern music. Revival 4000 features two iconic EQ options: the classic 4000 E Brown Knob (02) and the legendary Black Knob (242).

The Brown Knob EQ includes two fully parametric mid bands with SSL’s signature symmetrical design, ensuring consistent musical intervals around the centre frequency, no matter the gain or frequency settings. The high and low bands are 6 dB/octave shelving filters, with an option to switch to a fixed-Q bell response. This EQ became a staple of early '80s recordings and mixes.

Developed in 1983 the ‘242’ EQ circuit in collaboration with the legendary George Martin for the first SSL console installed at AIR Studios. Known as the Black Knob EQ, it introduced wider cut and boost ranges (±18 dB vs. ±15 dB), a refined control response, and a steeper 18 dB/octave high-pass filter—offering tighter low-end control and greater tonal flexibility.


Flexible Processing & Routing 


Revival 4000 includes a dedicated balanced insert point, allowing you to seamlessly integrate external outboard gear into the signal path. It also features a dedicated external sidechain (key) input, flexible processing order, and sidechain linking, ideal for pairing two units as a stereo setup.
