Focusrite SCARLET 18i8 3G Overview

Ideal for podcasters who need mix-minus functionality when taking calls, and perfect for producers and small bands, the third-generation Focusrite Scarlett 18i8 is an 18x8 USB audio interface offering high-performance hardware, input expandability, customizable mic tone, and a creative software bundle. The four improved Scarlett microphone preamps feature switchable phantom power, input pads, and selectable Air circuits, which add brightness based on Focusrite's legendary ISA preamplifier. The first two XLR-1/4" combo inputs can accept unbalanced instrument level from guitars, basses, synthesizers, and drum machines, or balanced line level from a mixing console or outboard preamps, while combo inputs 3-4 support mic- or line-level sources.

The rear panel sports four additional fixed-level 1/4" inputs to accommodate more line-level devices, and an ADAT optical input for use with an external 8-channel A/D converter. The Scarlett 18i8's 24-bit / 192 kHz converters ensure that signals are captured and reproduced with detail and clarity. With four balanced 1/4" line/monitor outputs, two 1/4" stereo headphone jacks, and independent control of the headphone and speaker volume settings, the Scarlett 18i8 can simultaneously feed multiple monitoring systems and outboard effects processors. The virtual loopback function empowers podcasters with an easy mix-minus setup for taking calls without the caller being distracted by a delayed audio return signal. Traditional 5-pin MIDI I/O is provided for seamless integration of MIDI equipment such as a keyboard or sound module, and S/PDIF coaxial ports allow proper routing of stereo digital gear. The Scarlett 18i8 connects to your Mac or Windows computer via USB and is powered by the included external power supply. The extensive software bundle includes music production software, virtual instruments, plug-in effects, loops, and more—plenty of tools to kick-start your inspiration.
