The Clarett 8Pre USB hardware interface provides the means for connecting microphones, musical instruments, line level audio signals and digital audio signals to a computer through the computer's USB port. The signals at the physical inputs can be routed to your audio recording software / digital audio workstation (referred to throughout this user guide as the DAW ); similarly, the outputs from the DAW can be configured to appear at the unit's physical outputs. Audio sources - mics, instruments, etc., can be recorded into your DAW and then played back from there through amplifiers and speakers, powered monitors, headphones, a mixer or any other analogue or digital audio equipment that you wish to use.The Clarett 8Pre USB is also a MIDI interface, allowing your computer to connect to other MIDI equipment in your studio. An important feature of the Clarett 8Pre USB is the analogue preamplifier design. In addition to their class-leading dynamic range and ability to provide all the gain you're ever likely to need, the circuitry now includes an exciting new AIR function. Individually selectable on each channel, AIR subtly modifies the pre-amp's frequency response to model the impedance and resonance characteristics of Focusrite's classic transformer-based ISA mic preamps.When recording with good quality microphones, you will notice an enhanced clarity and definition in the important mid frequency range, just where it is most needed for vocals and many acoustic instruments. The accompanying software application, Focusrite Control, is designed to require a minimal amount of user interaction, letting you easily configure the Clarett 8Pre USB with signal routings appropriate for the most common recording tasks. For more complex situations, it provides extensive routing and monitoring options, as well as the ability to control global hardware settings such as sample rate and synchronization.The Clarett sound - now on USBClarett USB lays down the challenge to interfaces twice the price. The Clarett USB range 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. Boasting 119dB dynamic range, Clarett can now be experienced with any Mac or PC supporting USB 2.0 and above.The perfect A-D and D-A conversionDecades 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 outsClarett 8Pre USB is an 18-in, 20-out audio interface. Six-segment LED metering easily shows the signal level of the eight mic/line inputs, two of which are also high-impedance instrument inputs that can record super-hot pickups with no unwanted distortion. MIDI I/O and S/PDIF I/O are also included. ADAT I/O allows you to expand your setup with up to eight extra inputs and outputs when combined with multi-channel mic preamps like Clarett OctoPre. Analogue outs include two monitor outputs with anti-thump technology, eight line outputs, two headphone outputs with volume controls and a word clock output for sending clock signal to external devices.The sound of ISAThe eight Air-enabled mic preamps can reproduce the input impedance, clarity and frequency response curve of our original ISA mic preamp.Super-low latency recordingClarett 8Pre 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 ClarettThe 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.Focusrite ControlConfigure your routing and monitor mixes from Mac, PC, iPad, iPhone or iPod touch with user-friendly control software Focusrite Control.Included softwareXLN Audio - Addictive Keys: one of four inspiring and interesting keyboard instrumentsFocusrite - Red Plug-in Suite: accurately models our classic Red 2 equalizer and Red 3 compressorSoftube - Time and Tone Bundle: four of Softube's world-class reverb, delay, mastering and distortion plug-insFocusrite - Plug-in Collective: exclusive offers, tutorial content and more, from some of the most innovative and prestigious plug-in companiesAbleton - Live Lite: Industry leading music-making softwareLoopmasters: 2GB of royalty-free sample librariesFocusrite ControlAdd more I/O without changing your interface - with Clarett OctoPreClarett 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.Includes: Focusrite Clarett 8Pre USB 18-In/20-Out Audio Interface - AC Mains Cable with IEC Connector - USB-C to USB-A Cable - USB-C to USB-C Cable - Focusrite 2 Year Limited WarrantySpecifications: Inputs: 18: analogue (8), S/PDIF (2), ADAT (8)Outputs: 8: analogue (4), S/PDIF (2), HP (2)Mixer: Fully assignable 26-in/10-out mixerSupported sample rates: 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz & 192 kHzFrequency Response: 20 Hz - 35 kHz +/-0.5 dB at minimum gainDynamic Range: 118 dBTHD+N: <0.001%Noise EIN: <-129 dBu (A-weighted)Maximum input level: +18 dBu at minimum gainGain Range: 57 dBFrequency Response: 20 Hz - 35 kHz +/-0.5 dB at minimum gainDynamic Range: 118 dBTHD+N: 0.001%Maximum input level: +26 dBu at minimum gainGain Range: 57 dBFrequency Response: 20 Hz - 35 kHz +/-0.5 dB at minimum gainDynamic Range: 117 dBTHD+N: 0.001%Maximum input level: +14 dBu at minimum gainGain Range: 57 dBDynamic Range: 118 dBTHD+N: 0.0007%Maximum Output Level (0 dBFS): +18 dBu at minimum gain, balanced line/TRS outputsDynamic Range: 115 dB (A-Weighted)THD+N: 0.0009%Maximum Output Level: +15 dBuConnectors: Combo XLR sockets: Mic/Line/Inst, on front panelMic/Line switching: AutomaticLine/Instrument switching: Via Focusrite ControlPhantom power: +48 V switches for inputs 1 to 4, 5 to 8Connectors: Combo XLR sockets: Mic/Line, on rear panelMic/Line switching: AutomaticPhantom power: +48 V switches for inputs 1 to 4, 5 to 8Main outputs: 10 x balanced 1/4 TRS jacks (on rear panel)Stereo headphone outputs: 2 x 1/4 TRS jack on front panelMain monitor output level control: On front panelHeadphones level controls: On front panelADAT Input: 2 x TOSLINK optical connectors: 8 channels at 44.1/48 kHz
