Focusrite SCARLETT 18i6
18i6 USB Audio Interface

The Focusrite Scarlett 18i6 is an 18 in / 6 out USB 2.0 audio interface designed to make home multitrack recording a breeze. Alongside two award-winning Focusrite preamps, six high-quality analogue inputs allow you to simultaneously record guitar, bass, vocals and keys. You don’t need to stop there either – pop in the ADAT optical cable from an outboard eight-channel mic pre unit such as the Focusrite OctoPre MkII and you can track the drums at the same time.

Included with the Scarlett 18i6 is Scarlett MixControl, an 18 x 6 DSP mixer. Offering a superb level of flexibility, the MixControl software enables you to create six separate mixes with ultra-low-latency. Route any combination of input signals and sequencer outputs to any of the Scarlett 18i6 outputs. Intuitive one-click configurations help you track, monitor and mix as quickly as possible. 

Scarlett 18i6 comes with all of the additional tools needed to start making music straight away. Scarlett VST/AU/RTAS Plug-in Suite comes in the box, adding Focusrite compression, reverb, gating and EQ to your recording system.

Focusrite’s established Xcite+ bundle is also included. The bundle features Ableton Live Lite (for all your production, performance and compositional needs), Novation’s Bass Station soft synth and over 1 gig of royalty-free samples from Loopmasters.
 
Scarlett 18i6’s two award-winning Focusrite preamps ensure low noise and distortion, whilst cutting-edge digital conversion captures your audio with pristine quality. 16 additional inputs allow you to capture inspired takes, without having to constantly re-patch your studio. Combined with the very latest in USB interfacing technology, excellent routing flexibility and rock-solid driver stability, the Scarlett 18i6 is the heart of the modern recording studio.
