FEATURES
The Clarett+ OctoPre is an eight-channel preamplifier for use with microphones, line and instrument
input signals. Both analogue and digital outputs are provided: the digital outputs are in ADAT format
on optical TOSLINK connectors, which can be easily routed to any ADAT-equipped interfaces using
optical cables. The Clarett+ OctoPre can transmit and receive eight channels of audio at sample
rates of 44.1, 48, 88.2, or 96 kHz, or four channels at 176.4 or 192 kHz.
The Clarett+ OctoPre has eight next-generation, high-performance Clarett+ preamps to capture
the clearest and most powerful audio with a preamp design that brings masses of headroom, low
distortion and low noise.
The new and improved high-performance A-D and D-A converters deliver extremely low noise and
high dynamic range audio, for making recordings that are more powerful than ever. Switchable
channel inserts on every channel keep Clarett+ OctoPre at the centre of your creative process and its
word clock input offers convenience and reliability for your system.
The ADAT inputs allow you to connect to an interface’s ADAT output - such as on the Clarett+ 8Pre –
to increase the number of output channels of your recording system.
