Solid State Logic SSL 18 USB-C Audio Interface

26-in / 28-out high-performance USB audio interface

A New Era Has Begun

Introducing SSL 18, a new era in rackmount production technology from Solid State Logic. Developed from decades of analogue and digital design expertise, SSL 18 delivers exceptional audio performance with a studio-ready feature set and the signature SSL sound trusted by professionals.

Best-In-Class Audio Performance

Next-generation 32-bit / 192 kHz converters deliver up to 120 dB dynamic range on all mic, line and instrument inputs, with 125 dB dynamic range on monitor and line outputs. Dual headphone outputs also deliver up to 120 dB dynamic range.

8 SSL-Designed Mic/Line Inputs

Eight high-performance SSL mic preamps with switchable Mic/Line modes deliver ultra-low noise and wide dynamic range. Legacy 4K Mode adds analogue saturation and classic SSL 4000-series character. Inputs 1 and 2 also support Hi-Z instruments.

10 Line Outputs

Ten balanced line outputs provide flexible studio integration. Outputs 1–4 are switchable between +9 and +24 dBu, while outputs 3–10 operate at +24 dBu. All outputs are DC-coupled for CV control of synths and modular systems.

Dual High-Performance Headphone Outputs

Two independent headphone outputs with selectable modes for Standard, High Sensitivity, and High Impedance headphones. Outputs can also function as additional line outputs.

Monitor Controller and Talkback

Integrated monitor controller with Alt speaker switching, custom monitor assignments, surround and immersive monitoring support, and dedicated talkback input with classic Listen Mic Compressor.

4K Legacy Analogue Enhancement

Inspired by SSL 4000-series consoles, Legacy 4K adds musical harmonic distortion and forward high-frequency character for iconic analogue tone.

Complete Digital I/O

Expand your system with 16 channels of ADAT I/O, 2 channels of S/PDIF I/O, and dedicated Word Clock output for rock-solid synchronization.

SSL 18 Mixer Powered by SSL 360°

Low-latency mixer provides full control of all inputs and outputs, performer cue mixes, mirror routing, and profile-based workflows.

Custom Monitor Control Assignment

Assign the front-panel monitor control to any analogue output or S/PDIF output for flexible surround and immersive monitoring setups.

Multiple SSL 18 Units

Expand up to 24 mic preamps by adding additional SSL 18 units configured as ADAT expanders.

Designed to Make Hit Records

Built by the same teams behind SSL’s legendary consoles, SSL 18 integrates seamlessly with professional outboard gear using +24 dBu capable I/O.
