The MicroBook is a USB bus-powered audio interface that delivers studio-grade audio performance in a compact size small enough to fit in your pocket.It gives users a complete personal recording solution for a Mac or PC laptop or desktop computer, with four simultaneous inputs for a microphone, a guitar, and a keyboard or other stereo line level device. The mic preamp delivers neutral coloration and pristine sound, with 20 dB pad and 48V phantom power for condenser mics. Programmable analog, digital, and headphone outputs provide flexible monitoring options.

The mic input preamp and A/D converter deliver pristine sound and transparent coloration. True 48V phantom power can be enabled, powered by the MicroBook's USB connection to the computer.

The MicroBook's Precision Digital Trim™ feature provides digitally controlled analog trim on all analog inputs. This gives users the best of both worlds: the excellent signal quality of analog audio circuitry and the fine-tune precision of digital control. Users can even save and recall trim settings on their computer.

The guitar input provides the proper impedance loads for guitars, so users can play through guitar processing plug-ins in their host software with confidence, knowing that they are getting natural feel and response. To make host plug-ins feel and sound even more like a real classic guitar amp, users can connect a MOTU ZBox impedance adapter.

The "mini" eighth-inch analog input can be used to connect an iPod or other stereo line level signal. Audio input can be mixed with other inputs and routed to any output pair. For example, a user could plug in a guitar and rehearse with a mix from his iPod. Or the input signal can be routed to the computer to be recorded or mixed in host software.

The MicroBook provides four pairs of outputs: balanced TRS quarter-inch main outs, stereo "mini" line out, S/PDIF digital out, and phones (on a stereo "mini" eighth-inch jack).

British analog mixing consoles are renowned for their musical EQ profiles. The MicroBook meticulously models these classic EQ curves to provide the very same, "magical" EQ settings found on these coveted desks. Seven separate filters are available on every input and output, including low-shelf and high-shelf, with intuitive graphic control of each EQ parameter via the CueMix FX software. Classic compression is also available, with individual settings for each input and output.
