SSL 2+.
Solid State Logic's Legacy 4K button adds the signature SSL high-end sheen and low-end punch to any source.
The Verdict.
Gavler Meta-Score
“The SSL 2+ is the interface for producers who want analog character from the tracking stage, not just in the mix. The Legacy 4K button adds genuine SSL console DNA to your recordings — not a plugin approximation, but an actual analog circuit. At $299, it is the most affordable way to get the SSL sound into your signal chain.”
The Gavler Verdict
Precision Engineering
Legacy 4K Button
Analog circuit modeled after the SSL 4000E console adds signature high-end sheen and low-end punch to any source.
SuperAnalogue Preamps
Two microphone preamps with 62dB gain deliver clean, transparent capture — add SSL character with the 4K button when desired.
MIDI I/O
Built-in MIDI input and output for hardware synthesizer and drum machine connectivity — uncommon at this price.
Technical Specifications
The Scoreboard
Experts value the Legacy 4K character and SSL pedigree. Community notes the preamps are transparent without 4K engaged, and the software bundle is excellent. Some prefer the MOTU M2's monitoring quality.

Global Critique
“The SSL 2 and 2+ hit back with excellent mic preamps that probably qualify as best in class. Mic preamp Equivalent Input Noise is an excellent -130.5 dBu (A-weighted), and dynamic range is quoted as 110.5 dB on the inputs and 112 dB on the monitor outputs.”
“The 4K Legacy button engages a combination of saturation and high-frequency boost that is said to emulate the sound of classic SSL 4000-series consoles. Like the very similar Air switch found on many Focusrite interfaces, it's an appealing effect, but one that could easily cause problems at the mix if over-used or applied to the wrong source.”
“Both product ranges justify the price differential. They have better audio specifications, they look and feel like professional devices, they sound good.”
