SSL 12 USB Audio Interface

The Solid State Logic SSL 12 is a desktop USB recording interface with four analogue microphone preamps. Each channel has gain control, phantom power and a selectable Legacy mode, while the front-panel instrument connections provide an alternative for compatible guitars and other high-impedance sources. Its advertised twelve-input configuration includes digital expansion: the optical ADAT input can add up to eight channels from suitable external equipment, rather than providing twelve physical analogue sockets.

The top-panel monitor control and headphone connections support recording and playback workflows. SSL 360 software provides a configurable mixer for monitoring and loopback, allowing computer playback to be routed into a recording or streaming application. Available ADAT channel counts depend on the selected sample rate and connected equipment.

SSL describes the interface as USB bus-powered, using USB 3.0 for power while audio communication follows the USB 2.0 protocol. This is an audio interface for use with a compatible computer, not a self-contained recorder. Microphones, external ADAT preamps, speakers and a computer are not included in this listing.
