Critic Reviews

Solid State Logic 18

soundonsound.com

Solid State Logic's SSL 18 USB Audio Interface straddles the line between semi-pro and professional, boasting impressive audio specs and a robust feature set. While its conventional design might initially underwhelm, the interface reveals significant capabilities, including versatile preamps and extensive input/output options. However, the user interface may pose a challenge for less experienced users, lacking the intuitive controls found in competitors like Focusrite. The absence of digital gain control and remote functionality adds to its learning curve. Ultimately, the SSL 18 stands out in its category but may require a steeper investment in time and understanding for optimal use.

The Solid State Logic SSL 18 presents a compelling mix of high-quality microphone preamps and flexible routing options, ideal for project studios. Its dedicated talkback input with an LMC circuit and robust build quality highlight SSL's heritage. However, the interface falls short in terms of generous cue mixes and lacks physical buttons for certain functions, which may frustrate users accustomed to more tactile controls. While it boasts impressive specs and a sleek design, it may not fully satisfy those expecting a complete pro-level experience. Overall, the SSL 18 is a solid choice but has notable limitations that potential buyers should weigh carefully.
