Solid State Logic (booth 18301) announced at the 2025 NAMM Show that it has launched the SSL 18 rackmount USB audio interface, marking the start of new rack-mount production technology from the company.
32-bit/192 kHz converters provide the platform for the SSL 18’s analogue design, with stated dynamic range performance of 120 dB across all of its microphone, line-level and instrument inputs. Meanwhile, its integrated high-current amplifier features dual headphone outputs offering 120 dB dynamic range.
Eight SSL-designed mic preamplifiers have a switchable Mic/Line configuration. A two-stage circuit design is designed to help ensure low distortion during recordings while maintaining the natural character of the source. Each input can also be flipped into Legacy 4K Analogue Enhancement Mode, which adds analogue saturation and a musical high-frequency boost – allowing users to access the iconic 4000 series sonic character for vocals, drums, and more. Inputs 1 & 2 are located on the front panel and offer instrument/Hi-Z inputs to capture DI’d guitars and vintage synths/drum machines.
“SSL 18 embodies our commitment to crafting a 19-inch rack audio interface that delivers SSL quality. Our engineering team applied their analogue and digital design expertise to exceed expectations,” says Andy Jackson, senior product manager, studio, for SSL. “With the powerful SSL 360 software, SSL 18 delivers a world-class studio experience to any setup. We’re eager for everyone to experience its sound and workflow.”
?The SSL 18 comes equipped with 10 balanced line-level outputs located on the rear of the unit. ? Line outputs 1 & 2 and 3 & 4 can be configured to +9 or +24 dBu, ensuring compatibility with a broad array of studio monitors and vintage equipment. Outputs 3 to 10 operate at +24 dBu, making them suitable for integrating professional outboard equipment. All outputs are DC-coupled and capable of sending Control Voltage (CV) to synthesizers and/or modular rigs. Additionally, SSL 18 features configurable analogue insert points for inputs 1 and 2, making it easier to track with analogue processing in the chain.
The interface also has a monitoring control section with talkback input. Line outputs 1 & 2 and 3 & 4 offer alternative loudspeaker switching with Alt Speaker and Cut controls located directly on the front panel. The talkback input can be flipped into LINE mode for processing the audio through the classic SSL Listen Mic Compressor — for crushing drums, parallel vocals, and more. Using the SSL 360 software, these features and many others can be customized to a user’s workflow.
The SSL 18 is scalable to meet the needs of any user and is a companion to SSL’s forthcoming ALPHA 8 (expected February/March 25). The mic or line level I/O count can be increased by 18 channels using its ADAT and S/PDIF connections. Also, SSL 18’s dedicated Word Clock output is designed to provide solid clocking for integrating any external digital devices.
The interface comes bundled with the SSL Production Pack that offers a selection of virtual instruments, plug-ins, samples and DAWs, including Harrison Mixbus 10 (worth over $1,100). Additionally, users receive an extended 6-month trial of Complete Access which includes every plugin from SSL, Slate Digital and Harrison Audio.
