Overview
Introduction
Experience the definitive sound of SSL console heritage, with Revival 4000 – an all-in-one analogue channel strip brimming with character and versatility. For the first time ever, the most revered circuits from the B and E-Series consoles unite to deliver the ultimate analogue channel strip for your studio productions.
The 4000-Series revolutionised music production, setting a new industry standard that went on to shape countless iconic records. It all began with the rare SL 4000 B console. Originally launched in 1976, and later installed in London’s Townhouse Studios, the 4000 B was used to create ground-breaking hits like `Intruder’ by Peter Gabriel and the seminal gated-drum sensation `In the Air Tonight’ by Phil Collins.
This set the tone for the most influential mixing console of all time – the SL 4000 E. Launched in 1979, the 4000 E became the heartbeat of legendary studios like Abbey Road, Electric Lady, and The Hit Factory, empowering 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 the sonic signatures of generations.
With its revolutionary channel strip design, surgical yet musical EQ and punchy compression, the 4000 E transformed the way records were made, delivering the clarity and cohesion that defines platinum-selling hits to this day. Its signature, focused midrange clarity, unmatched precision, and the unmistakable glue and punch of its channel and bus compression, became the sound of popular music. Feedback from producers and engineers who first used the 4000 E’s EQ and dynamics processing was unanimous: it was an incredibly musical and intuitive tool. Designed by people who truly understood the recording and mixing process, it reassured engineers and producers in an era where you had to get things right the first time – when mistakes were costly, the 4000 E made it significantly easier to realise your creative vision.
From Bruce Springsteen and Madonna to Dr Dre and Daft Punk, artists across pretty much every genre relied on its unmistakable sound. By 1996, a staggering 83% of Billboard #1 hits had been produced on an SSL console. The 4000-Series didn’t just change music – it immortalised an era, leaving a legacy that continues to inspire to this day.
Some legends fade away ­ the 4000-Series is immortal.
With Revival 4000, you can now tap into that rich legacy, giving your mixes the same punch, presence and precision heard on records that have defined generations.

Unpacking
The unit has been carefully packed and inside the box you will find the following items. Revival 4000 IEC power cord for your country Safety Sheet
It is always a good idea to save the original box and packaging, just in case you ever need to send the unit in for service.
Rack Mounting, Heat and Ventilation
Revival 4000 is a 1U, 19″ rackmount piece of equipment designed to sit in the racking of a producer’s desk or similar. It is recommended that ventilation space is left above and below the unit so any heat generated by Revival 4000 can naturally disperse. The sides of the unit’s chassis have cut-outs that should under no circumstances be blocked or covered. Always allow the unit to cool down before handling.

Power on the unit by pressing the silver power button on the right-hand side.
Input Stage
Microphone Preamp & Line Trim
Revival 4000 uses the exact same Jensen JT-115K-E transformer-balanced preamp circuit as found on the original 4000 E-Series console.
MIC The microphone preamp control provides +20 to +70 dB of gain. This control does not affect the line-level input path.
48V Provides +48V phantom power, required for certain condenser and active ribbon microphones.
PAD Introduces a 20 dB pad ahead of the microphone preamp gain control. Useful for microphones that have higher sensitivity/a high output level and therefore require less gain.
Ø The Ø (polarity) button inverts the polarity, useful for multi-miked sources that may be suffering from phase cancellation. It affects whichever input path is selected (Mic or Line).
LINE Switches the input to the line-level input on the rear panel (LINE IN), instead of the microphone input. The line-level input is sourced post the microphone preamp and therefore the MIC control does not function when LINE is selected.
TRIM The line trim provides an additional +/- 20 dB of clean gain post the microphone preamp gain. This control also affects the line-level input path if LINE is selected.

Tutorial
One-Knob De-esser
The de-esser section deploys the original de-esser circuit from the 4000 B console’s channel compressor/limiter (set to ‘ds’ mode), with a 10:1 ratio and 7 kHz high-pass filtered side-chain, delivering broadband compression triggered by sibilance. A key element of the musicality comes from the fact that the circuit design mirrors that of the SSL Bus Compressor (but with the additional filtering in the side-chain). It is ideal for tasks such as taming harsh vocals or drum overheads.
IN Toggles the De-esser circuit in/out.
THRESHOLD A threshold from +10 to -20 dB allows you to dial in the amount of de-essing required to tame harsh ‘ess’ sounds – great for vocals and drum overheads. 3 x LEDs are indicate the amount of de-essing (3, 6 and 10 dB)
By default, the De-esser is located near the front end of the signal flow (pre-Dynamics and EQ) but it can be re-positioned to be post-EQ via the DE-ESS POST EQ button in the ROUTE section.
Dynamics
The compressor/gate design returns faithfully to the circuit and components that defined the sound of the original 4000 E-Series channel strip. The side-chain uses a true RMS converter and the gain reduction element is an all-discrete design, identical to the Class A VCA chip used in the original console. The compressor also contains additional switching options to defeat the soft-knee curve, a fast attack mode and choice of logarithmic or linear release curve. The result is a compressor with many distinct voicings, all of which contributed to the many classic records tracked and mixed on E-Series consoles.

As in the original E-Series channel strip, the Filter and/or the Equaliser section can be assigned to the dynamics side-chain allowing further technical or creative manipulation of the signal the compressor reacts to. e.g. Filtering out some low-end in the compressor side-chain may be especially important for bass-heavy music. This is achieved by engaging the DYN S/C button(s) in the Filters and EQ sections. The Dynamics side-chain can also source from an external input – see the ROUTE section for more details.
By default, the Dynamics section is ahead of the Equaliser in processing order but this can be reversed by engaging the DYN POST EQ button in the ROUTE section (4000-Series console owners may be more au fait with this button being labelled as ‘CH OUT’ ;)) Processing order and side-chain options are covered in more detail in the Signal Flow Options and To Side-Chain Processing sections of the user guide.
If you have two Revival 4000 units in use across a stereo source, the S/C LINK allows the side-chain control signals of multiple units to be linked. For more detail, refer to the Routing section of the user guide.
DYN IN Toggles the Dynamics section (Compressor/Limiter & Gate circuits) in/out.

Tutorial
Compressor/Limiter
RATIO When turned to 1:1, the Compressor/Limiter section is inactive. Turning the control clockwise increases the compression ratio to give a true limiter at the fully clockwise position.
The compressor ordinarily has a soft-knee. Engaging the button changes this to a hard knee, providing an alternative, more aggressive character.
THRESHOLD Whenever a signal exceeds the level set by this control, the compressor will start to act at the ratio set by the RATIO control. This control also provides automatic make-up gain, so as you lower the threshold and introduce more compression, the output level is increased, maintaining a steady output level regardless of the amount of compression.
RELEASE Sets the time constant (speed) with which the compressor returns to normal gain settings once the signal has passed its maximum.
FAST ATT Provides a faster attack time (3 ms for 20 dB gain reduction). When off the attack time is slower and less aggressive (30 ms for 20 dB gain reduction).
LIN REL Changes the release curve from logarithmic to linear. This also raises the threshold by 6dB.
GAIN REDUCTION LEDS The yellow and red LEDs, on the top of the LED display area, indicate the amount of gain reduction (compression).

Revival 4000 User Guide

Tutorial
Gate/Expander
The Expander/Gate section can act either as a :1 Gate or, when the EXP switch is pressed, a 2:1 Downwards Expander.
RANGE Determines the depth of gating or expansion. When turned fully anti-clockwise, the Expander/Gate section will be inactive. When turned fully clockwise, a range of 40 dB can be obtained.
THRESHOLD Variable hysteresis is incorporated in the threshold circuitry. For any given `open’ setting, the Expander/Gate will have a lower `close’ threshold. The hysteresis value is increased as the threshold is lowered. This is very useful in music recording as it allows instruments to decay below the open threshold before gating or expansion takes place.
RELEASE This determines the time constant (speed), variable from 0.1 ­ 4 seconds, at which the Gate/Expander reduces the signal level once it has passed below the threshold. Note that this control interacts with the RANGE control.
FAST ATT Provides a fast attack time (100 s per 40 dB). When off, a controlled linear attack time of 1.5ms per 40 dB is selected. The attack time is the time taken for the Expander/Gate to `recover’ once the signal level is above the threshold. When gating signals with a steep rising edge, such as drums, a slow attack may effectively mask the initial `THWACK’, so you should be aware of this when selecting the appropriate attack mode.
The green LEDs in the display section indicate Expander/Gate activity (the amount of gain reduction).
Filters
In common with the original E-Series Channel strip, a pair of High and Low-Pass Filters are provided. Both Filter controls incorporate bypass switching, which is activated when turned fully anti-clockwise; turning either control up will put that band in circuit, illuminating the LED adjacent to the control to indicate this state. The Filters are normally placed post EQ but can be repositioned to be just after the input stage (post-Insert), or, into the dynamics side-chain. Both Filters normally exhibit a 12dB/octave but pressing the BLK switch in the EQ section will modify the slope of the High-Pass Filter to 18dB/octave.
DYN S/C Switches the Filters into the side-chain of the Dynamics section. The Equaliser can also be switched into the side-chain independently. Note that DYN S/C overrides the INPUT function (see below).
INPUT Moves the Filters to put them in circuit near the front-end of the channel strip – post Input Stage and Insert Point, pre-De-esser, Dynamics and EQ. This allows the Filters to be used to clean up signals before compressing or equalising them.

Tutorial
Equaliser
The Revival 4000 Equaliser section defaults to the original `Brown Knob’ circuit that was standard on all early production E-Series consoles. The two parametric mid-band sections feature SSL’s classic logarithmically symmetric design that ensures that the ±3dB up/down points retain the same musical interval from the centre frequency regardless of frequency and amplitude settings. The two shelving sections are traditional 6 dB/octave designs with an option for a fixed Q parametric response (Bell). The `02′ EQ, to give it its correct name, was used on countless recordings and mixes in the early eighties. In 1983 a new EQ circuit, the ‘242’, was developed in conjunction with the legendary George Martin for the first SSL console to be installed in AIR studios. The `Black Knob’ EQ, as it became known, featured enhanced cut and boost ranges (±18 dB instead of ±15 dB) together with a different control law and a steeper 18 dB/octave High-Pass Filter for tighter control of low frequencies. The design is activated by pressing the BLK switch.
As mentioned above, the EQ section has some function buttons associated with it: EQ IN Switches the EQ section into circuit. BLK Switches the EQ from 02 `Brown Knob’ operation to 242 `Black Knob’ operation. DYN S/C Switches the EQ into the side-chain of the Dynamics section. The Filter section can be switched independently of the EQ section. If both Filter and EQ sections are assigned to the dynamic side-chain, the Filter section precedes the EQ.

Routing
The ROUTE section provides a number of processing order and side-chain routing possibilities.
DYN (POST EQ) Moves the Dynamics section to be post the EQ.
DE-ESS (POST EQ) Moves the De-esser section to be post the EQ.
EXT (DYN S/C) Enables the Dynamics side-chain to be sourced from an external (key) input, connected to the rear panel DYN S/C INPUT EXT Combo XLR/TRS Jack input. For full flexibility, FILTERS TO DYN S/C and EQ TO DYN S/C will still affect the external side-chain source if engaged.
LINK If you have 2 x Revival 4000 units connected together using the S/C LINK TRS/TS jack connections on the rear of the unit, the side chain control signals will be linked by pressing the LINK buttons on the front panel of both units. When two Dynamics sections are linked, the control voltages of each section sum together, so that whichever section has the most gain reduction will control the other one (loudest signal wins).
This is particularly useful and important when using 2 x Revival 4000s as a stereo pair. as it ensures that both channels react uniformly to the loudest signal present in either the left or right side of the mix. This prevents the stereo image from shifting or “wobbling” due to one side being compressed more heavily than the other. By letting the loudest signal trigger equal gain reduction across both compressors, the stereo balance remains stable and musical, which is critical for preserving a solid, punchy stereo image on busses like drums, guitars, or the mix bus.
There are some important things to be aware of when linking in this way: · You can use either a TRS or TS jack for linking two units – it does not matter which type is used. · Ensure both units have their LINK buttons engaged. · Both sets of front panel Compressor control positions, button states and gain staging into the compressor must be manually
matched across both units. · The front panel Dynamics compression LEDs continue to monitor the individual internal side-chains, not the combined control
voltage that is actually driving the VCA for compression. Therefore, the front panel compressor gain reduction LEDs may make it seem like one unit is compressing more than the other. However, providing all steps above have been followed, the reality is the compressor will be maintaining a rock solid stereo image. The LEDs continuing to monitor their individual side-chains is useful as it gives you an indication of which side-chain signal is ‘winning’ at any particular moment and therefore driving the compression activity.

Balanced Insert
Revival 4000 has a balanced insert point for incorporating additional outboard processing equipment into the signal chain. The SEND and RETURN TRS Jacks are located on the rear of the unit.
IN In true SSL fashion, the Insert Send is always active and engaging the IN button activates the Return path to introduce the processed audio into Revival’s signal path.
OP By default, the Insert point is located immediately after the input stage, ahead of the De-esser, Dynamics, EQ and Filters. Pressing the OP button relocates the insert point to be at the end of the processing chain (post all of the sections mentioned above) but pre the Output Trim control.
Output Stage and Metering
OUT A dedicated Output Trim provides an additional +/- 20 dB of clean gain at the end of the signal chain for full control of the signal level exiting via the Balanced Output.
METER 5 LEDs provide signal level metering at the following points: · +24 dBu · 12 dBu · 0 dBu · -12 dBu · -24 dBu
MTR INP Normally, the meter reads the output of the channel but selecting MTR INP will meter the signal immediately after the input section.

Dynamics Controls
The unit contains a complete dynamics section, the functions of which split into two areas; a Compressor/Limiter and an Expander/ Gate.

Compressor/Limiter Controls Ratio Threshold Attack Slope Attack Time Release Release Slope

Parameter Ranges Variable from 1 to infinity (limit) Variable from +4 dB to ­26 dB Normally `Soft Knee’, switchable to `Hard Knee’ Normally 30 ms per 20 dB, switchable to 3 ms (`Fast Att’) Variable from 0.1 to 4 seconds Normally `Logarithmic’, switchable to `Linear’

The Compressor/Limiter has two different attack slope modes and two different release slope modes; `Soft Knee’ & `Hard Knee’ and `Logarithmic’ & `Linear’ respectively. As their names suggest these modes affect of manner of response to incoming signals. Combining the two modes provides four very different modes of compression and limiting with the `Hard Knee’ and `Linear’ modes giving far more dramatic compression characteristics.

Expander/Gate Controls Range Threshold Attack Time Release Time

Parameter Ranges Variable from 0 to 40 dB Variable from ­30 dB to +10 dB Normally 1.5 ms per 40dB, switchable to 100 s Variable from 0.1 to 4 seconds

The side chain signal can be sourced either from the signal feeding the dynamics section or the external side-chain input. The Filters and/or the EQ can be inserted in the side-chain. LED meters independently indicate amount of compression and expansion.
