Three models make up the Clarett USB line 15/01/18
Focusrite says that they have introduced a new range of USB audio interfaces – beating interfaces twice the price or more. They tell us that the Clarett USB line features specially designed high performance, low-noise (-128dB EIN) mic pres with a low distortion, ultra-linear design that guarantees a clean, open and transparent sound, giving accurate representation of the original performance. Three interfaces appear in the series: Clarett 2Pre USB (10-in, 4-out), Clarett 4Pre USB (18-in, 8-out) and Clarett 8Pre USB (18-in, 20-out).Here's more details in Focusrite's own words...
Boasting up to 119dB dynamic range, Clarett can now be experienced with any Mac® or PC supporting USB 2.0 and above. The included standard USB and USB Type-C™ cables connect to Mac® or PC, and you can record with super-low latency through amp simulators and effects plug-ins.
Decades of analogue circuit design experience, applied around 24-bit/192kHz A-D and D-A conversion, delivers a superior signal path. In addition, the Air-enabled mic preamps can reproduce the input impedance, clarity and frequency response curve of our original ISA mic preamp. Included software is from XLN Audio, Focusrite, Softube, Ableton® and Loopmasters.
The most compact of the three interfaces, Clarett 2Pre USB provides two mic/line/instrument inputs, four line outputs, MIDI I/O and an ADAT input. Clarett 4Pre USB and Clarett 8Pre USB add mic/line inputs, S/PDIF I/O and two headphone outputs with volume controls.
