Solid State Logic SSL18 USB-C Audio Interface (SSL18/SSL-18)

Solid State Logic introduces SSL 18, the first-ever rackmount USB-C audio interface from the legendary audio company, built on decades of expertise in analog and digital design. Delivering the signature SSL sound and premium quality trusted by professionals, the SSL 18 26-in / 28-out interface is a powerhouse for recording, producing, and mixing with confidence and precision.

 

Featuring cutting-edge 32-bit next-generation converters, eight high-performance SSL-designed mic preamps, two Hi-Z instrument inputs, the versatile SSL 360° advanced digital mixer, Legacy 4K analog enhancement, and comprehensive digital and MIDI I/O, the SSL 18 streamlines your workflow while elevating the capabilities of your studio setup.

• Next-generation 32-bit/192 kHz converters provide the platform for SSL 18’s analog design to shine, with unrivaled dynamic range performance of 120 dB across all microphone, line-level, and instrument inputs.
• Experience 125 dB dynamic range on the monitor and line outputs to hear your music with uncompromised fidelity.
• The dual-headphone outputs offer 120 dB of dynamic range for accurate monitoring in any environment.

• SSL 18 features eight high-performance SSL-designed mic preamps with switchable Mic/Line configuration. The preamps deliver ultralow-noise recordings and a huge dynamic range, making sure you capture every detail of the performance with stunning accuracy.
• The 2-stage circuitry ensures ultralow distortion while maintaining the natural character of the source—or flip them into Legacy 4K mode to add real analog saturation and the iconic 4000 Series sound to vocals, drums, and more.
• Located on the front panel, inputs 1 and 2 also offer instrument/Hi-Z inputs to capture DI’d guitars and vintage synths/drum machines.

• SSL 18 comes equipped with ten balanced line-level outputs located on the rear panel. To ensure optimal signal integrity and maximize headroom, line outputs 1&2 and 3&4 can be configured between +9 and +24 dBu. This ensures 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.

• 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.

• 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 distills the two essential characteristics of the 4K sound into a single design. Legacy 4K Analog 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.

• 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.
• MIDI I/O are available on 3.5mm TRS jacks.

• 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, Talk, 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.
• Switch the talkback input into Line Mode and reprocess audio through the classic Listen Mic Compressor, perfect for crushing drums, parallel vocals, and more.

• The SSL 18 digital mixer offers comprehensive management of all inputs and outputs, as well as detailed, scalable input metering in the 360° Software.
• Create and manage the control room monitor mix.
• Configure a further four monitor 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.
• For podcasts, Stereo Loopback with selectable loopback source enables audiences to hear virtual guests or system audio with ease.

• The included SSL Production Pack features a selection of must-have virtual instruments, plug-ins, samples, and DAW to fuel your creativity and bring your productions to life.
• As an eligible SSL interface owner, claim the 6 months free Complete Access subscription—giving you access to every plug-in from Solid State Logic, Slate Digital, and Harrison Audio.
