Compact and competitively priced, the SOLID STATE LOGIC SSL2+ : USB AUDIO INTERFACE desktop 2x4 USB audio/MIDI interface puts legendary SSL analog character, pristine conversion, and intuitive console-style workflow within reach for producers, home recordists, musicians, and songwriters on a tight budget.

Its two SSL-designed mic preamps—accessible via XLR-1/4" combo inputs—feature class-leading gain, headroom, and noise specs for tracking mics, electric instruments, or line-level signals with ultraclean definition. When you want some character added on an input, simply press that channel's Legacy 4K button to add a high-frequency boost and sweet harmonic distortion, both inspired by the classic and heralded 4000-Series consoles used on countless hit records.

Both input channels, which are arranged vertically like a large-format mixing board, also provide 5-segment LED metering and selectable 48V phantom power per channel. The SSL 2+ is equipped with a pair of monitor outputs and two independent high-current headphone outs with high dynamic range, independent level control via Alps pots, and a selectable mono/stereo monitor mix.

Additionally, it features four unbalanced RCA outputs—two mirror the 1/4" monitor outs and two serve outputs 3-4—for routing to external cue amps or effects units. Utilize the rear-panel MIDI I/O ports for hooking up external synths and keyboard controllers without having to integrate a separate MIDI interface.

The layout of the interface harkens back to SSL's classic large-format analog consoles, featuring a prominent monitor level knob and smaller controls for your headphone out and monitor mix. The monitor mix knob can be used to counter any latency while recording at high buffer rates in your DAW by sourcing the monitor signal directly from the input path. Or rotate the knob to the right to introduce more of the USB return from your computer for easy overdubs.
