Equally comfortable in the studio or as part of a mobile rig, the Focusrite Clarett 4Pre USB 18x6 USB Audio Interface combines 24-bit / 192 kHz A/D/A conversion, low-latency monitoring, and a multitude of I/O options with four, Air-enabled microphone preamps that can model the sound of the company's classic ISA preamps. With low noise (-128 dB EIN), low distortion, and 118 dB dynamic range, the high-performance mic preamps deliver a clean, open, and transparent sound, for accurate reproduction of the original performance. The Clarett 4Pre USB is equipped with four front panel mic/line inputs, two of which have high-headroom instrument inputs for recording hot pickups without distortion. Each mic pre has a separate gain knob with a Gain Halo meter that makes it easy to set the correct input level. The interface also provides two line level outputs, two monitor outputs with anti-thump technology, MIDI I/O, stereo S/PDIF I/O, and eight channels of ADAT inputs to expand your setup. The front panel features two 1/4" headphone outputs with independent volume controls. A pair of +48V phantom power switches allow you to turn on phantom power for condenser microphones on channels 1 and 2 and 3 and 4 respectively. The Clarett 4Pre USB offers a comprehensive software package that includes the Focusrite Red Plug-In Suite with accurate models of the Red 2 EQ equalizer and Red 3 Compressor, the Softube Time and Tone Bundle with reverb, delay, mastering, and distortion plug-ins, a Loopmasters library with 2GB of royalty-free samples, and more. Also provided is the Focusrite Control software that enables you to configure your routing and monitor mixes from Mac and Windows computers, or iPad, iPhone, and iPod touch devices.
