Focusrite Scarlett 18i8 USB Audio Interface, 3rd Gen

Overview by GAK

Focusrite’s Scarlett 18i8 USB audio interface features two high headroom instrument inputs, eight balanced line inputs to connect synths or other line-level audio, four balanced outputs for monitoring and effects sends and four monitor outputs, with anti-thump tech and speaker switching. Compared to the 2nd-gen version, the 18i8 has an additional pair of TRS lineouts.

At the top of the Scarlett series of USB audio interfaces are the 18i8 and 18i20. They’re by far the most versatile as they give you the greatest selection of inputs and outputs. Just like all the aforementioned Scarletts, the 18i8 and 18i20 have been enhanced as part of the third generation.

As well as the loopback functionality that was added to the 4i4 and 8i6, the 18i8 and 18i20 now have alternate speaker switching which is accessible via the Focusrite Control software.

Its high channel count and compact size give it a stunning balance of portability and flexibility. The 18i8 is a great choice for studio owners who need a variety of inputs and world-class sound and engineers that want a portable multi-track recording solution.

In the unlikely event your interface lets you down, all brand-new Scarletts come with a three-year warranty from Focusrite and their support team is friendly and knowledgeable.

The Clarett 4Pre USB is the “premium” version of the 18i8 and is worth checking out if you’re looking to upgrade or have some extra cash in your soundcard budget. The 4Pre USB has the same I/O configuration as the 18i8 but boasts a quicker latency performance and superior Clarett preamps, which Focusrite claim to be the finest pre-amp they’ve built into a USB interface.
