Focusrite Clarett+ OctoPre 8-channel ADAT Preamp
Need more channels from your Clarett interface? The Focusrite Clarett OctoPre is for you.
8-IN, 8-OUT. OVER ADAT
Clarett 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 AIR
The 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 our original ISA mic preamp.
MIC, LINE AND INSTRUMENT INPUTS
The 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 POINTS
Each 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 OUTPUTS
The 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 CONVERSION
The 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.
- The ideal Clarett I/O expansion kit:With eight Clarett mic pres, eight line outputs and ADAT interfacing, the Clarett OctoPre is the ideal way of adding inputs and outputs to your Clarett Thunderbolt audio interface – or any other interface with ADAT I/O.
- The sound of transformer mic preamps: The eight specially-designed Clarett mic preamps include a switchable analogue 'Air' effect that imparts the sonic signature of the classic Focusrite ISA mic pre.
- Focusrite precision conversion: 24-bit A-D and D-A conversion at standard sample rates all the way up to 192 kHz, with up to 118dB dynamic range A-D and 119dB dynamic range D-A (A-Weighted) to capture every nuance in recording and mixing. Up to eight channels of A-D and eight channels of D-A (four channels at 176.4/192kHz).
- Eight high-quality analogue outputs: Feed them from the mic pres directly to a mixer in a live environment, simultaneously capturing your audio digitally via twin ADAT outputs. Or drive them from the ADAT inputs, giving you up to eight additional analogue outputs from your DAW.
- Dedicated switched insert points on every channel: Track through your favourite analogue outboard equipment such as compressors, gates and EQ with maximum flexibility via dedicated switched insert points with clip indicators on every channel. Leave inserts permanently connected to your outboard gear or patchbay and switch them in and out as required.
- Mic preamps optimised for tracking drums: Clarett Octopre is designed not to clip, with preamps optimised to handle extreme levels from sound sources like kick drum and snare.
- Two quality instrument inputs: Clarett Octopre's first two channels feature extreme-headroom DI's, ready for you to plug in your guitars and bass, instantly accessible on the front panel and able to take the highest level pickup without distortion.
- Six-segment LED input metering on every channel: Clarett Octopre's fast-acting input meters provide clear reference of input levels, helping you to avoid analogue or digital clipping. Additional pre-insert clip indicators ensure accurate gain staging when using outboard equipment.
- 48V Phantom power on every channel: Switched in two groups (1-4 and 5-8), every channel is capable of supplying phantom power for use with condenser microphones.
- Versatile clocking solutions:Clarett OctoPre provides rock solid, super stable clocking performance with wordclock I/O for synchronisation with other studio equipment.
