The Solid State Logic SSL 18 is a state-of-the-art, rackmount USB-C audio interface that combines professional-grade audio performance, advanced connectivity, and a robust feature set designed to elevate the workflows of recording, producing, and mixing professionals.

Unparalleled Audio Performance

Solid State Logic has applied its legendary expertise in analogue and digital engineering to create a next-generation audio interface with unrivalled sound quality. The SSL 18 boasts 32-bit/192 kHz converters that deliver an exceptional 120 dB dynamic range across all microphone, line, and instrument inputs. The line and monitor outputs achieve an extraordinary 125 dB dynamic range, providing unmatched clarity and detail in audio playback. Dual high-performance headphone outputs also feature a 120 dB dynamic range, ensuring pristine sound reproduction for detailed monitoring and critical listening.

Precision Microphone Preamps and Legacy 4K Analogue Enhancement

The SSL 18 includes eight SSL-designed mic preamps with switchable mic/line configurations. These preamps feature ultra-low noise and distortion, maintaining the natural tone of the source while capturing every nuance of the performance. The inclusion of the Legacy 4K analogue enhancement mode adds a touch of classic SSL character, delivering harmonic richness and a musical high-frequency boost reminiscent of the iconic SSL 4000 series consoles. Inputs 1 and 2, located on the front panel, offer instrument/Hi-Z inputs for directly connecting guitars, vintage synths, and drum machines.

Comprehensive Output Flexibility

Equipped with ten balanced line-level outputs, the SSL 18 ensures seamless integration into any studio setup. Line outputs 1–4 offer configurable output levels between +9 dBu and +24 dBu for compatibility with both modern studio monitors and vintage equipment. All outputs are DC-coupled, enabling them to send control voltages to modular synths and other CV-capable devices. This ensures precise signal integrity and operational versatility for producers and engineers.

Customisable Headphone Monitoring

The SSL 18 provides two independent headphone outputs with configurable modes to accommodate various headphone impedances. Users can select from "Standard," "High Sensitivity," or "High Impedance" settings, enabling personalised monitoring. The headphone outputs can also serve as line-level outputs, adding further flexibility to the interface.

Extensive Digital I/O Options

SSL 18 supports a wealth of digital audio connections, making it a hub for modern production environments. It features 16 channels of ADAT I/O and two additional channels of S/PDIF for expanding your studio's input and output capabilities. A dedicated word clock output ensures reliable synchronisation with external digital devices, maintaining accurate timing across complex systems.

Integrated Monitor Control and Talkback Functionality

SSL 18 includes a professional monitor controller section with alternative speaker switching and dedicated talkback functionality. The talkback input can also be switched to line mode, allowing creative use of the legendary SSL Listen Mic Compressor for processing audio. These features, combined with user-configurable monitor control buttons via the SSL 360 software, streamline control room workflows.

SSL 360-Powered Mixer

The SSL 18 mixer, powered by SSL 360 software, offers comprehensive management of all inputs and outputs. Users can create custom monitor mixes, manage control room setups, and utilise flexible routing for feeding external monitoring systems, outboard effects, or additional recording devices. The Mirror Routing system ensures precise and scalable input-to-output configuration, ideal for tracking and mixing sessions.
