Our editorial take on the SSL 12 USB Audio Interface
The Solid State Logic SSL 12 is a 12-in / 8-out USB audio interface designed with portability and production in mind. It uses USB bus power and features 32-bit / 192 kHz AD/DA conversion. Its combination of four mic/line inputs, two Hi-Z inputs, and ADAT input provides a flexible I/O count for its class, along with console-style software mixing.
Targeted at content creators and producers, the SSL 12 aims to deliver studio-quality recording capabilities in a compact form factor. The individually selectable 48V phantom power on each mic input adds to its versatility, while the inclusion of MIDI I/O supports integration with external hardware.
While offering a robust set of features for its size, the absence of an onboard display or a pad option for the inputs might require users to rely more heavily on software for certain adjustments. Its core strengths lie in its high-resolution audio processing, SSL's preamp reputation, and its suitability for mobile setups.
