Focusrite Clarett 4Pre USB Audio Interface - Used  From Focusrite

Features The Clarett 4Pre 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 Thunderbolt™ 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 you wish to use. Although all inputs and outputs on the Clarett 4Pre are routed directly to and from your DAW for recording and playback, you can configure the routing within your DAW, or within the Focusrite Control application, in order to meet your precise needs.

The Clarett 4Pre also has connectors for sending and receiving MIDI data; this lets you use it as a MIDI interface between your computer and other items of MIDI equipment in your system.

An important feature of the Clarett 4Pre is the new design of analogue preamplifier. 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 4Pre 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 synchronisation.

All inputs on the Clarett 4Pre are routed directly to your DAW software for recording, but Focusrite Control also allows you to route these signals internally within the device to the outputs so you can monitor the audio signals with ultra-low latency - before they arrive at your DAW, should you need to do so.
