MOTU 8Pre 8 channel Mic Preamp Audio Interface

An Impressive Standalone Interface, or a Fantastic Augmentation
A veritable swiss army knife of an audio interface, the 8Pre includes 8 pristine microphone preamps to deliver world-class audio quality. But it's not just a pre-amp unit. With two banks of ADAT optical ports, it can patch in seemlessly to your existing studio set up, providing an extra 8 channels of recording capability. In addition, utilizing MOTU's CueMix DSP functionality, it provides the flexability to route audio and create independent monitor mixes and heacphone mixes with zero latency.

Digital Mixing made Easy
Use the included CueMix™ software to mix all 16 inputs from your computer. Eight channels of ADAT optical I/O make the 8pre an ideal companion for a digital mixer. Two ADAT lightpipe connections work together to support a full 8 channels of optical digital I/O at any sample rate up to 96kHz.

Myriad Connections and Monitoring Options
Connect all of your studio gear, including microphones, guitars, synths, keyboards, drum machines and even effects processors. Then monitor all of these live inputs via the 8pre’s main outs or headphone jack — with virtually no monitoring latency and no processor drain on your computer. You can even create separate monitor mixes for the main outs and headphones. Control everything, including talk-back and listen-back, from the included CueMix Console™ software, just like a large studio console.

16 Channel MIDI Interface Included
The 8pre includes a 16-channel MIDI interface. Simply connect the 8pre to your computer with any USB cable, and both MIDI and audio are ready to go. Connect any MIDI device, such as a controller keyboard, synth module, automated control surface or drum machine. Timing is sample-accurate with supporting software.

Compatible with Mac and Windows
The 8pre provides cross-platform compatibility with Mac OS X (10.6 or higher), Windows (8/7/Vista) and all of your favorite audio software and host-based effects via WDM/ASIO/Core Audio drivers. Or you can use the included AudioDesk workstation software for Mac OS, with 24-bit recording/editing and 32-bit mixing/processing/mastering.

Retrofit to existing MOTU Interfaces
The 8pre is really two products in one. When it is not connected to a computer via USB, the 8pre functions as an eight-channel analog to digital (optical) converter at the 88.2 or 96kHz sample rates.. Connect the 8pre to your MOTU 828, 896, Traveler or even another 8pre via the optical “lightpipe” connection to add eight high-quality microphone pre-amps to your system. Since the connection is digital, 100% pristine sound is maintained, down to the very last sample.

Augment Your Existing Set Up
The 8pre is the perfect way to instantly add eight more mic inputs to any audio interface or digital mixer with optical I/O. If you have a MOTU interface with on-board CueMix DSP mixing, such as the 828 (mkII or mk3), 896 (HD or mk3) or Traveler (original or mk3), the 8pre inputs appear directly in the host interface's CueMix mixer to becomes a transparent extension of your system, operating together with your primary interface as a single, integrated unit — even when the host interface is not connected to a computer and is instead operating as a stand-alone mixer.
