The Solid State Logic SSL 2+ Audio Interface is a compact, high quality, desktop audio interface. With 2 inputs and 4 outputs this interface brings the legendary SSL preamps into a small form factor for home studio use.

It has two SSL-designed mic preamps (XLR / 1/4″ Combination Jacks) with up to 62dB of gain available. If you’re looking for something extra, you can use the SSL Legacy 4K button to add a high-frequency boost and subtle distortion, both inspired by the classic SSL 4000-Series consoles.

I consider myself to be half entrepreneur and half A/V geek. I am never content to settle for what is expected or determined by others to be the “industry standard”. Instead, I work extremely hard to break new ground and deliver value to whoever I meet.

My passion for the audio visual industry drives me to create content that will help others learn the best tools and techniques to learn how to setup their home studio.
