Hispasonic: Product of the year

“Where Focusrite have laid down the challenge to other manufacturers, though is in the sound quality of these devices, which offer audio specifications previously unheard of in this price bracket.”

“…the Focusrite Clarett 8Pre offers outstanding value for money (really), the latency claims seem to stand up to scrutiny and the sound is gorgeous, especially when used with the air option. Add to this the ease of set-up and you have a killer offering.

“I was absolutely able to record and monitor through my DAW without noticeable delay.”

“A very solid interface for a whole host of applications – very highly recommended indeed.”

*These quotes refer to the Clarett Thunderbolt range.

The perfect A-D and D-A conversion

Decades of analogue circuit design experience, applied around 24-bit/192kHz A-D and D-A conversion, delivers a superior signal path. Hear your music sound better than you've ever heard it sound before.

Ins and outs

Clarett 4Pre USB is an 18-in, 8-out audio interface. Gain Halo meters make it easy for you to set the input level of the four mic/line inputs, two of which are also high-impedance instrument inputs that can record super-hot pickups with no unwanted distortion. Four fixed line inputs are also included, and the ADAT input supports an additional eight channels when combined with multi-channel mic preamps like Clarett OctoPre.

Outs include two monitor outputs with anti-thump technology, a headphone output with volume control, and two line outputs. MIDI I/O is also included.

The sound of ISA

The four Air-enabled mic preamps can reproduce the input impedance, clarity and frequency response curve of our original ISA mic preamp.

Clarett Air frequency response

Super-low latency recording

Clarett 4Pre USB connects to Mac® or PC using the included standard USB and USB Type-C™ cables. Record with super-low latency through amp simulators and effects plug-ins.

The clarity of Clarett

The Clarett range is acclaimed for its sound quality. It's due partly to Clarett's specially-designed mic pres with the unique "Air" effect, adding air and clarity especially to vocals and acoustic instruments. Plus Focusrite's precision digital conversion, carefully balancing noise floor, dynamic range, frequency response and distortion for the best possible sound to and from your DAW.

We invited audio engineering professionals to a blind listening test at Riverside Studios in Berlin to compare the sound of Clarett to that of the Apollo 8p, from Universal Audio, makers of the Apollo Duo; and the Apogee Ensemble.

Add more I/O without changing your interface - with Clarett OctoPre

Clarett OctoPre lets you add eight additional 'Air'-enabled mic/line preamps - including two front-panel instrument inputs - each with a switched insert for outboard processors, and eight line outputs. Mic pres and A-D/D-A conversion are identical to the rest of the Clarett range. Clarett OctoPre connects to the ADAT light-pipe ports on your Clarett interface - or any system with ADAT I/O. Feed the mic pres to the analogue line outs to drive a live board while you record via the digital outputs. Or drive them from the ADAT inputs to add eight more DAW channels to an analogue mix.
