The SSL 2+ is Solid State Logic's original desktop 2-in/4-out USB-C audio interface for songwriters and project studios, carrying the brand's mic preamp with a '4K' legacy-console harmonic mode. Two rear Neutrik combo jacks accept mic, line, or Hi-Z instrument, with 48V phantom and switchable 4K. Balanced 1/4-inch TRS main outputs drive studio monitors, with a parallel RCA pair mirroring them and an independent RCA 3/4 output for headphone cue sends or DJ software. Two front 1/4-inch headphone outs and 5-pin DIN MIDI I/O complete the feature set over a USB-C (USB 2.0) host link.
SSL’s desktop 2-in/4-out USB-C (USB 2.0) interface with Neutrik combo preamps, ‘4K’ mode, TRS + RCA outs, dual headphones, and 5-pin MIDI.
