The SSL 2+ is the brand’s second-most-affordable piece of hardware ever launched. SSL is going head-to-head with other interface makers like Focusrite, PreSonus, MOTU, Audient and possibly Behringer. However, the question is, can SSL produce an affordable USB audio interface without cutting corners or devaluing its brand image with a sub-standard product?
The SSL 2+ has a USB-C port for connecting to its host computer, whether a Mac or PC. Annoyingly, the SSL 2+ doesn’t include a physical power switch and is hub powered from the host computer. This arrangement works perfectly well, although I would have liked a proper switch to turn the interface off when it’s not in use. The alternative of pulling out the USB cable to turn the SSL 2+ off could end up weakening the port over time.
Both channels have a button below the gain knob marked “4K”. Pressing this button puts the interface into a simulation mode imitating the sound of SSL’s Iconic 4000 Series console. The result is a high-frequency EQ boost bringing in a more vintage and sound. The effect is not dissimilar to the Air switch on a Focusrite Scarlett interface, which adds a bit of warmth and richness to the output.
