Solid State Logic ALPHA 8

Building on the highly regarded Alpha Link range, Solid State Logic introduces the ALPHA 8 - an 8-in/8-out professional-grade analogue-to-digital and digital-to-analogue converter, ideal for expanding your audio interface via ADAT and S/PDIF. Alternatively, you can configure the ALPHA 8 to handle all analogue and digital I/O simultaneously via USB, providing an 18-in, 18-out audio interface. With class-leading conversion, flexible routing, and flawless audio performance, the ALPHA 8 unlocks the full potential of your setup.

Equipped with next-generation 32-bit/192 kHz converters, the Alpha 8 brings SSL-grade audio performance to your studio. With an expansive dynamic range, incredibly low THD+N, unmeasurable crosstalk, and an exceptionally low noise floor, the Alpha 8 provides pristine line-level audio for your analogue outboard processing, samplers, synths, and drum machines. The compromise is over - capture your sound with the quality it truly deserves.

The ALPHA 8 offers a wide range of AD/DA routing configurations to suit your specific needs, ensuring you can fully utilise all its digital and analogue I/O capabilities. Whether you require a straightforward bidirectional Analogue <> ADAT/SPDIF converter, an 18-in/18-out USB audio interface, or a combination of both, the ALPHA 8 provides highly flexible routing options for its analogue and digital I/O.

The operating level of each analogue input and output on the ALPHA 8 can be individually adjusted to +9, +18, +20, or +24 dBu, ensuring optimal signal integrity and maximising headroom for devices connected to it. Whether it’s 19” rack gear, vintage synthesizers, analogue mixers, 500-series modules, or monitor controllers, the ALPHA 8 ensures every connection is fully optimised. On the digital side, Word Clock in and out, along with ADAT and S/PDIF clocking options, guarantee exceptional digital audio performance, providing jitter-free, rock-solid integration into your studio environment while enhancing the overall performance of your creative space.

The ALPHA 8 is the ultimate audio interface expander for producers and engineers seeking to integrate SSL sound and quality into their existing setup. It also serves as the ideal companion to the SSL 18. Instantly expand the I/O of the SSL 18 via ADAT, adding 8 channels (1 x ALPHA 8) or 16 channels (2 x ALPHA 8s). This makes it perfect for seamlessly incorporating additional analogue outboard processing, analogue mixers, and more.

The flexible analogue and digital routing of the ALPHA 8 unlocks a wide range of workflow possibilities. Create hardware insert paths for 500 Series modules, outboard EQs, compressors, or hardware FX. Use the S/PDIF I/O for external metering or amp simulators. Alternatively, make the ALPHA 8 your primary interface, seamlessly connecting analogue and digital devices to your DAW via USB-C. For electronic music producers, the ALPHA 8’s outputs can also deliver Control Voltage, allowing you to control synthesizers, modular rigs, and CV-enabled FX pedals.

For decades, SSL has been supporting world-class artists, producers, and engineers in creating exceptional music and audio. Recognising the importance of having the right tools, we’ve partnered with leading industry brands to offer the SSL Production Pack, bundled free with your ALPHA 8 audio interface.
