Solid State Logic SSL2+ MK2

Solid State Logic SSL2+ MK2 – 2-in/4-out USB audio interface with 32-bit 192 kHz converters, dual SSL mic preamps, Legacy 4K circuit and CV-ready balanced outputs

The SSL2+ MK2 is a professional-grade USB audio interface designed for musicians, producers, and engineers who demand pristine sound quality, flexible I/O, and legendary SSL analog character in a portable format. Equipped with two next-generation SSL mic preamps featuring up to 64 dB of gain, low-noise performance (-130.5 dBu EIN), and instrument/line switching, it captures everything from vocals to guitars with stunning detail. The built-in Legacy 4K analogue enhancement switch adds musical harmonic richness and high-end lift inspired by the classic SSL 4000 consoles.

SSL2+ MK2 offers balanced 4 x TRS outputs with 120 dB dynamic range, ideal for monitor pairs or CV routing to modular synthesizers via DC-coupled outputs. Two front-facing high-current headphone outputs (with NJM op-amps) ensure optimal performance even with high-impedance headphones. Additionally, a stereo loopback feature makes it ideal for streaming or capturing internal audio. Bundled with the SSL Production Pack – a premium software suite including Vocalstrip 2, Drumstrip, Melodyne Essential, Amplitube 5 SE, Mixbus 10, and more – SSL2+ MK2 is a complete production hub ready for studio or mobile use.
