Solid State Logic has a streamlined, professional solution for expanding the I/O of your existing audio interface. Building on the success of the company’s renowned Alpha Link lineup, Alpha 8 is a professional-grade 8 x 8 A/D-D/A converter that’s ideal for expanding your audio interface via ADAT and S/PDIF. The Alpha 8 also functions independently as an 18 x 18 USB audio interface. This impressive versatility, combined with class-leading conversion, flexible routing, and unrivaled SSL audio performance, makes the Alpha 8 indispensable for unlocking the full potential of your recording setup.
SSL audio quality, versatile configurability
Equipped with SSL’s state-of-the-art 32-bit/192kHz converters, Alpha 8 delivers no-compromise audio with massive dynamic range along with vanishingly low distortion, noise, and crosstalk. Its line-level connectivity lets you extract maximum performance from your outboard processing gear, samplers, synths, and drum machines. Alpha 8’s routing can be configured in many different ways to meet your precise needs. Whether you need a simple bidirectional analog-to-ADAT+S/PDIF converter, an 18-in/18-out USB audio interface, or any combination of the two, Alpha 8 gives you the routing flexibility to accommodate even the most challenging projects.
Rock-solid performance, smooth integration
With the Alpha 8, each analog input and output operating level can be set individually to +9, +18, +20, or +24dBu, ensuring optimized signal integrity and maximized headroom for any connected devices. Whether you’re running rackmount equipment, analog mixers, 500 Series modules, or monitor controllers, every connection to your gear is fully optimized. On the digital side, word clock in and out, ADAT, and S/PDIF clocking options ensure Alpha 8 delivers optimal digital audio handling, guaranteeing rock-solid, jitter-free performance and smooth integration into your studio environment while streamlining your workflow.
A world of workflow potential
The Alpha 8’s versatile analog and digital routing unlocks a world of workflow potential. Create hardware insert paths for 500 Series modules, outboard equalizers, compressors, or hardware effects units. Integrate external metering or amp simulators via S/PDIF. Another option would be to use Alpha 8 as your primary interface, seamlessly connecting digital and analog devices to your DAW using USB-C. For electronic music producers, the Alpha 8’s outputs are capable of outputting CV to control synthesizers and other CV-equipped gear.
Alpha 8 + SSL 18
The Solid State Logic Alpha 8 is a superior audio interface expander for engineers, artists, and producers seeking to expand their studio with world-class SSL sound quality. For the ultimate SSL setup, however, we recommend you consider combining the Alpha 8 with the SSL 18 high-performance 26 x 28 USB audio interface, which would instantly expand SSL 18’s I/O via ADAT, adding eight channels (with one Alpha 8) or 16 channels (with two Alpha 8s).
The Solid State Logic legacy
Since its founding by Colin Sanders in 1969, Solid State Logic has followed a design philosophy that prioritizes the needs of artists, engineers, and producers. The company's products facilitate creativity by removing technical impediments and streamlining workflows. Firmly ensconced in the pantheon of pro audio greats, SSL helped shape the history of pro audio.
