Key details include 2-in / 4-out USB-C audio interface, Two SSL-designed mic preamps with 62 dB gain and 24-bit/192 kHz AKM converters.
The specification also includes Legacy 4K analogue enhancement mode, Two independent headphone outputs and MIDI I/O + additional stereo monitor outputs. With an audio interface, the useful specification is the one that matches a real recording setup. Input count determines how many sources can be captured at once, while preamps, instrument inputs, monitor outputs and headphone facilities define the day-to-day workflow.
Bus power can make a compact interface easier to move between desks or laptops, while larger units often exchange portability for extra I/O, routing or expansion. On SSL 2+, Direct monitoring with blend control and USB-C bus-powered are also part of the specification.
Sample-rate figures are easy to compare, but physical connections and monitoring controls usually have a bigger effect on everyday use. The main compromises to keep in mind are Only two mic/line inputs and No ADAT expansion.

In practice, that makes SSL 2+ easier to compare with nearby alternatives because the important trade-offs are visible in the specification.

That keeps the buying decision grounded in practical needs.
