Solid State Logic SSL18 Audio Interface and Alpha 8 Converter/Expander | NAMM 2025

Description
The SSL Alpha 8 is a professional-grade 8x8 audio converter that elevates your studio with impeccable sound quality and flexible connectivity. Featuring next-generation 32-bit/192kHz converters, you'll capture every nuance with stunning clarity, immense dynamic range, ultralow noise and negligible distortion—bringing true SSL-grade performance to your rig.
Ultimate Audio Interface Expander
With its versatile routing capabilities, the Alpha 8 seamlessly integrates into your setup as the perfect audio interface expander. Connect via ADAT for up to eight channels of analog-to-digital and digital-to-analog conversion or leverage S/PDIF for an additional two channels bidirectionally. You can even configure it as an 18-in/18-out USB interface, giving you simultaneous control over all analog and digital I/O from your DAW.
Optimized Signal Integrity for Every Connection
The Alpha 8 ensures optimal signal transfer by allowing you to individually set the operating level for each analog input and output to +9, +18, +20 or +24dBu. This maximizes headroom and maintains pristine signal integrity when connecting rack gear, analog mixers, 500-series modules, monitor controllers and more. On the digital side, comprehensive clocking options with Word Clock I/O, ADAT and S/PDIF guarantee jitter-free performance.
Seamless Integration With SSL 18 and Studio Outboard
While the Alpha 8 is an exceptional interface expander for any setup, it's the perfect partner for SSL's flagship SSL 18 interface. Simply connect one or two Alpha 8 units via ADAT to instantly gain eight or 16 additional channels of I/O for effortlessly integrating analog outboard, mixers and more. The flexible routing also allows creating hardware insert paths for 500-series modules, EQs, compressors and effects processors.
Unlocking New Creative Possibilities
The Alpha 8 empowers you to expand your workflow in innovative ways. Use the S/PDIF connections to incorporate external metering or amp simulators. Electronic musicians can even route control voltages from the DC-coupled outputs to modular synths and CV-enabled effects pedals. And with the included SSL Production Pack software bundle—featuring virtual instruments, plugins, samples and a DAW—you have all the tools to bring your ideas to life.
