Best-In-Class Audio Performance
Next-generation 32-bit/192 kHz converters provide the platform for SSL 18’s analogue design to shine, with unrivalled dynamic range performance of 120 dB across all microphone, line-level and instrument inputs – capture your sources like never before. Experience 125 dB dynamic range on the monitor and line outputs to hear your music with uncompromised fidelity. Need to work on headphones? No problem, with the unbeatable 120 dB dynamic range on offer from the dual-headphone outputs.
32-Bit / 192 kHz / Unrivalled Analogue and Digital Performance
8 x SSL-designed Mic/Line inputs
SSL 18 features eight high-performance SSL-designed mic pre’s, with switchable Mic/Line configuration. Leveraging our renowned engineering expertise, they deliver ultra-low noise recordings and a huge dynamic range, making sure you capture every detail of the performance with stunning accuracy. Their advanced 2-stage circuitry ensures ultra-low distortion while maintaining the natural character of the source – or flip them into Legacy 4K Mode to add real analogue saturation and the iconic 4000 series sound to vocals, drums, and more. What’s more, in Line mode the mic preamp stage is completely bypassed – perfect for connecting external outboard gear. Located on the front of the unit, inputs 1 & 2 also offer instrument/Hi-Z inputs to capture DI’d guitars and vintage synths/drum machines.
120 dB Dynamic Range / -130.5 dBu EIN / Legacy 4K Analogue Enhancement
10 x Line-outputs
SSL 18 comes equipped with ten balanced line-level outputs located on the rear of the unit. To ensure optimal signal integrity and maximise headroom, line outputs 1&2 and 3&4 can be configured between +9 and +24 dBu, providing seamless compatibility with a wide range of studio monitors and vintage equipment operating at lower levels. Outputs 3 to 10 operate at +24 dBu, perfect for integrating professional outboard equipment. For producers, all outputs are DC-coupled and capable of sending control voltage to synthesizers and modular rigs.
125 dB Dynamic Range / +24 dBu operating levels / Main & Alt Speaker Switching / DC-Coupled Outputs
Dual High-Performance Headphone Outputs
Custom headphone mixes with two independent headphone outputs, configurable for different types with ‘Standard’, ‘High Sensitivity’, and ‘High Impedance’ settings. SSL 18’s headphone outputs can also be repurposed as line-level outputs for added flexibility.

Dual Independent Outputs
Configurable Headphone Modes
Monitor Controller + Talkback w/Listen Mic Compressor
SSL 18 features a full monitor controller section with built-in talkback input. Line outputs 1&2 and 3&4 offer alternative speaker switching with Alt and Cut accessible via the monitor controls located on the front panel. Alternatively, customize the monitor controls via SSL 360 and tailor them to your workflow. SSL 18 also features a dedicated talkback input channel that can operate in MIC or LINE mode. LINE mode is great for re-processing audio through the classic Listen Mic Compressor – crush drums, parallel vocals, and more.

4K Legacy Analogue Enhancement on Every Analogue Input Channel
The SSL 4000 series consoles (often referred to as ‘4K’) are renowned for imparting a unique ‘mojo’ to sounds and instruments that pass through them. This mojo comes from multiple stages of harmonic distortion from compressor VCAs, VCA faders, and other crucial components such as the transistor mix amps. Using modern components, SSL has developed a circuit that distils the two essential characteristics of the 4K sound into a single design. Legacy 4K Analogue Enhancement injects a controlled amount of finely-tuned, sweet-sounding harmonic distortion and a ‘forward’ yet musical high-frequency EQ boost into the signal path, giving your sound the 4K mojo and presence that artists and engineers have loved for decades.
Real Analogue Saturation / Musical High-Frequency Boost / Immortal 4K sound
Complete digital I/O
A host of digital audio connections means that SSL 18 is ready to expand your I/O count whenever you are, with an additional 16 channels via ADAT and a further two via S/PDIF. SSL 18’s dedicated Word clock output provides rock-solid clocking for integrating external digital devices into your system.

SSL 18 Mixer, Powered by SSL 360°
The SSL 18 mixer offers comprehensive management of all inputs and outputs, as well as detailed, scalable input metering in SSL 360°. In the SSL 18 mixer you can create and manage the control room monitor mix, as well as configure up to four independent mixes for performers. In addition, a flexible Mirror Routing system allows you to route any input or aux master directly to an output – perfect for feeding personal monitoring systems, external metering and outboard FX. Create different templates for tracking, mixing and more, then save them as a profile in the SSL 18 mixer.
Designed to make hit records
Designed by the same engineering teams behind the esteemed range of analogue and digital mixing consoles, SSL’s rich heritage can be found throughout the design and feature set. SSL 18 is the only product in its category that is designed to properly integrate with professional outboard gear, thanks to the +24 dBu capable inputs and outputs.
