Focusrite Scarlett 18i8 3rd Gen USB Audio Interface

This compact USB interface is packed with 4 Scarlett mic preamps and extensive I/O, including 2 Hi-Z instrument inputs, 8 line inputs, S/PDIF, ADAT and MIDI.
The third-generation Focusrite Scarlett 18i8 is the perfect audio interface for recording engineers and producers who need to adapt to their recording environment, wherever they are.

Get a closer look at the Scarlett 18i8 in this video from Focusrite:

High-Quality Inputs

It offers eight analogue inputs: four mic/line inputs, two high-impedance, high-headroom instrument inputs and four additional fixed-line inputs on the rear. An optical input allows for expansion of up to eight additional channels for larger recording sessions. And with improved A-D and D-A conversion, your recordings and playback will sound clear and pronounced up to 24-bit/192kHz, vital to helping you perfect your mix.

Scarlett 18i8 features four of Focusrite’s best-ever-performing third-generation Scarlett mic preamps: with optional Air setting to reproduce the Air effect of their original ISA mic preamp, giving your vocal or acoustic recordings a brighter and more open sound. There’s a pad on every mic preamp to accommodate higher-level signals without clipping.

Scarlett 18i8 offers two extra line outputs over the previous generation, and speaker switching technology for dual monitor setups. Two independent headphone outputs allow for both engineer and artist to monitor during recording sessions, and a pair of virtual loopback inputs allows you to capture a stereo feed of any combination of hardware input and software playback channels –- making podcasting, live streaming and sampling tasks easier.

"The 18i8 Is Great Performing,Low Cost USB Studio In-A-Box"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Nice upgrades to an already awesome interface. The AIR preamp option, plus the added OUTS, made this a serious replacement for the Clarett. We have purchased two of the 18i8 units and both work fine in Windows. We use the 18i8, also an RME Babyface Pro, with various analog and optical preamps, and the Focusrite has become a real fave. Great music can be recorded with these.
