The MOTU MicroBook II is an updated version of your compact, studio-grade audio interface, the Microbook, that turns any Mac or PC into a personal 4 x 6 recording studio with professional I/O and monitor mixing. The MicroBook II will replace the original model at the same price. The MOTU MicroBook II comes in a compact, super durable cast metal case suitable for on-the-go recording, personal studio tracking, laptop-based DJ-ing, and many other recording and playback activities. At only 5.5 x 3.5 x 1.25 inches, the bus-powered MicroBook II has all the great features of the original model, plus hands-on volume control, USB 2.0 connectivity for low-latency performance, more simultaneous outputs (six), an XLR microphone input, and support for 96 kHz recording and playback.

"For discriminating you who insist on the very best audio quality, MicroBook II delivers unmatched performance for compact, personal recording," said MOTU Marketing Director Jim Cooper. "Plug in a mic, guitar, keyboard, and powered speakers, then enjoy audio fidelity that rivals other audio interfaces in the six to eight hundred dollar range."

I/O engineered for audio fidelity
The four inputs (mic, hi-Z guitar, and stereo balanced line in) can be recorded simultaneously. The microphone preamp delivers neutral coloration and pristine sound, with 20 dB pad and 48V phantom power for condenser mics.

Engineered for exceptional audio quality, the MicroBook II has balanced analog connectors and digitally controlled analog trim. Input trim is controlled separately from input mix volume, so that you never have to sacrifice audio fidelity for a balanced mix.

The MOTU MicroBook II provides six channels of computer output on eight physical outputs (four pairs): balanced TRS quarter-inch main outs, stereo "mini" line out, S/PDIF digital out, and phones (on a stereo quarter-inch jack). The S/PDIF digital output always mirrors the main outs.

Advanced features
Internal CueMix mixing and routing features let you program a different stereo mix for each output pair, consisting of any combination of live inputs and host audio tracks. Alternately, you can send the same mix to multiple outputs, or choose a separate output for the MicroBook's built-in test tone generator or white and pink noise generator.

The driver provides an extra input and output pair for routing complete mixes back to the computer host, for scoping audio streams with the analysis tools in the included CueMix FX software, and for routing virtual instrument (or other host) output to the MicroBook II mixer.

On-board effects include modeled analog EQ and compression, which can be applied with near-zero latency (in the hardware) to live inputs.

MOTU MicroBook II is everything you need to make world-class recordings

The MOTU MicroBook II provides simultaneous inputs for a microphone, a guitar, and a keyboard or other stereo line level device. The microphone preamp delivers neutral coloration and pristine sound, with 20 dB pad and 48V phantom power for condenser mics. Programmable outputs provide flexible monitoring options.

Ultra-compact size
Take it with you anywhere

The MicroBook II is an impressively small 5.5 by 3.6 by 1.25 inches, which means that it slides easily into your backpack - or a large pocket.
It also sits nicely next to your laptop
or desktop computer.

Studio-grade sound
Engineered for the discriminating ear

The MOTU MicroBook II has been engineered with MOTU's renowned, award-winning audio interface technology, which delivers the uncompromising audio quality and rock-solid performance MOTU interfaces are known for worldwide. You can always record and mix with confidence, even in most demanding professional recording situations, knowing that decades of engineering experience are behind you, every step of the way. The MicroBook II delivers measured audio specs that rival interfaces costing hundreds more.

High-speed USB 2.0
High bandwidth and low latency

The MOTU MicroBook II can record and play all channels simultaneously, and high-speed USB 2.0 provides plenty of bandwidth, even at 96 kHz.

Flexible volume control
Digital encoders push and turn

The two digital rotary encoders not only look good, they feel good, too. Push the volume knob repeatedly to cycle among the main outs, headphones, or both, as indicated by the LEDs. For the microphone input, adjust trim and toggle 48V phantom power or the -20 dB pad. Hands-on control is immediate and intuitive.

Mixing and effects
It's an 8-bus digital mixer, too

The MicroBook is an 8-bus digital mixer that lets you mix live inputs with each other - with or without host software tracks. With CueMix FX running on your computer, you can create separate mixes of live audio from your mic, guitar, and keyboard, and send each mix to separate outputs (main out, line out, and phones out) or any combination of all three.

Solid metal chassis
MOTU interfaces are built to last

The MicroBook aluminum alloy chassis is lightweight, yet incredibly sturdy and durable, and designed to withstand the rigors of the studio, stage, and tour bus. In a world awash with cheap plastic, the cool touch of the MicroBook II's metal exterior in your hands is a reassuring reminder that you are holding quality engineering and construction built to last.
