Focusrite Clarett Octopre: The Ultimate AD/DA Converter & Preamp
• 8 Channel Mic Pre and AD/DA converter for professional audio recording.
• Eight Clarett mic pres with extra air for exceptional sound quality.
• Precision 24-bit converters with up to 192kHz sample rate for hi-res audio.
8-In, 8-Out. Over AdatClarett OctoPre gives you eight Clarett mic pres renowned for their transparency, and eight outputs too. You can use these to extend the capabilities of your Clarett audio interface or any other interface fitted with ADAT optical inputs and outputs.
Eight Clarett Mic Pres with Extra AirThe eight mic pres have been designed specifically for the Clarett range, with plenty of gain, yet low noise and distortion – and great sound quality. They are Air-enabled, so can reproduce the input impedance, clarity and frequency response curve of their original ISA mic preamp.
Mic, Line and Instruments InputsThe front panel includes dual instrument inputs featuring extra headroom to handle the loudest pickup, while the rear panel includes universal XLR/jack connectors for the remaining auto-switching mic/line inputs.
Insert PointsEach input has its own switched insert point for single-cable connection of compression, equalisation and other outboard analogue processing – with hardwired relay bypass so you can leave outboard gear or a patchbay connected ready to access at the press of a button.
Eight OutputsThe Clarett OctoPre offers up to eight ADAT digital channels feeding 25-pin DSub rear-panel analogue outputs, making it useful for mixing as well as tracking. The line outputs can optionally provide feeds from the mic pres – useful for feeding a live console while recording the digital outputs.
Precision Digital ConversionThe Clarett OctoPre's precision 24-bit converters operate at standard sample rates all the way up to 192kHz – ideal for hi-res audio – with up to 118dB (A-D)/119dB (D-A) dynamic range. Hear your recordings sound better than you've ever heard them sound before.
