Solid State SSL18

4.9/5.0By AudioProHome Team

The Solid State SSL18 (often referred to as the SiX or BiG SiX in professional circles depending on the specific configuration) represents the pinnacle of desktop audio production. This isn't just an interface; it's a true analog console shrunk down to fit on your desk.

For professional producers, mixing engineers, and serious home studio owners, this is the closest you can get to having a large-format SSL console in your bedroom.

SuperAnalogue™ Preamps

The SSL18 features the same SuperAnalogue™ mic preamps found in SSL's large-format Duality and AWS consoles. These are transparent, fast, and incredibly detailed, capturing your source with absolute purity.

G-Series Bus Compressor

The legendary G-Series Bus Compressor is built right into the main mix bus. This is the "magic glue" that has been used on countless hit records to make mixes sound cohesive, punchy, and professional. Having this available in the analog domain on your desktop is a game-changer.

Analog Summing

Unlike standard interfaces that sum audio digitally, the SSL18 offers true analog summing. This provides a depth, width, and headroom that is difficult to replicate in the box.

Professional Routing

With professional routing options, insert points, and monitor control, it acts as the central hub of a complex studio setup, allowing you to integrate outboard gear seamlessly.

Verdict

If you demand the absolute best and want the legendary SSL sound in a compact format, the Solid State SSL18 is in a league of its own. It's an investment in professional sound.

Frequently Asked Questions

Is this a digital or analog mixer?

The SSL18 (BiG SiX) is a true analog mixing console with a built-in USB audio interface. The summing, EQ, and compression are all 100% analog.

Does it have the "4K" mode?

No, the "4K" mode is found on the SSL 2/2+ interfaces. The SSL18 uses SuperAnalogue™ preamps, which are cleaner and higher fidelity, similar to the AWS and Duality consoles.

Can I use it to sum my mix?

Yes! One of its main features is analog summing. You can route your stems from your DAW through the SSL18's analog channels and sum them through the G-Series Bus Compressor for that "big console" sound.

Is it bus powered?

No, due to the high-voltage analog rails and extensive feature set, it requires an external power supply (included).
