Equally comfortable in the studio or as part of a mobile rig, the Focusrite Clarett+ 4Pre desktop 18x8 USB Type-C audio/MIDI interface combines upgraded 24-bit / 192 kHz AD/DA conversion with low-latency monitoring and four Air-enabled microphone preamps that can model the sound of the company's classic ISA preamps. With low noise (-129 dB EIN), massive dynamic range, and even less distortion than before, the high-performance mic preamps deliver a clean, open, and transparent sound, for accurate reproduction of the original performance.
In addition to the four mic/line preamps (two with Hi-Z capability), the interface offers four rear-panel line inputs, an optical ADAT port for digital input expansion, S/PDIF stereo digital I/O, and MIDI I/O for integration of MIDI equipment such as a keyboard or drum machine. Four line-level outputs and two stereo headphone outputs let you properly hook up monitors, headphones, and more. The Clarett+ 4Pre includes a software package featuring Focusrite Red plug-ins and a channel strip that accurately models the rare Focusrite Studio Console. Also provided is the Focusrite Control software that enables you to configure routing and monitor mixes from Mac and Windows computers, or iPad, iPhone, and iPod touch mobile devices.
