Focusrite Clarett Octopre is an interface and AD/DA converter that provides 8 mic preamps and 8 outputs. You can use it to extend the capabilities of your Clarett Thunderbolt or any other interface. The mic preamps have been designed specifically for the Clarett range, with plenty of gain, with all the low noise and distortion and great sound quality. They include a special "Air" feature that switches to an analog model of the classic Focusrite ISA allowing a "transformer resonance effect", giving your microphone the air and clarity of an ISA transformer-based microphone pre-recording. In addition, the microphone preamps have plenty of headroom and are ideal for recording percussion and other extreme level sources.

The front panel includes dual instrument inputs with additional free space to handle the highest recording, while the rear panel includes universal XLR / jack connectors for the remaining auto-switching mic / line inputs. In addition, each input has its own switched insert point for the connection of a single cable of compression, equalization and other external analog processing with cable relay bypass so that you can leave outboard equipment or a patchbay connected ready to access the press of a button.

In addition to providing eight microphone preamps with 24-bit, 192kHz A-D conversion, Clarett OctoPre offers D-A conversion of up to 8 digital ADAT channels powered by 25-pin DSUB outputs from the rear panel, which is useful for mixing, as well as tracking. The line outputs can optionally provide line level output feeds from the microphone preamp to feed a console, for example, while recording the digital outputs. Apart from the insert point, the Clarett OctoPre is balanced end-to-end for exceptional noise immunity.
