1. Plug in your dynamic or condenser
mic here.
Use the MIC digital rotary encoder
on the top panel (4) to engage the
-20 dB pad (push) and/or 48V
phantom power (push and hold)
for a condenser mic, if necessary.
Make sure 48V power is
turned OFF BEFORE plugging
anything in to the mic input.Only
engage 48V power when a device
that requires it is plugged in.
2. Plug in your guitar here using a
standard quarter-inch guitar
cable.This input is designed with
the high-impedance characteris-
tics necessary to properly handle
both passive and active guitar
pickups.To make your guitar
sound and“feel”even more like it
is plugged directly into a actual
guitar amplifier,consider using
MOTU’s ZBox guitar impedance
adapter (sold separately),which
simply goes between your guitar
cable and this input (no extra
cable needed).
3. This is a standard quarter-inch
headphone jack.To control
volume,push the VOL rotary
encoder (5) repeatedly until the
phones LED is lit.You can control
phone volume independently or
together with main out volume.
To obtain your product
serial number,see
“Obtaining your
MicroBook serial
number”on page 14.

1. Connect to a host computer with a
standardUSB cable (TypeA toType
B).When connected to laptop or
desktop computer,the MicroBook
IIc is powered by this USB 2.0
connection.
2. This USB 2.0 Micro-B jack is for
power only.
DO NOT use this port
to connect to a host computer.Use
it for power when connecting the
MicroBook IIc to an iPad.For
details,see “Connecting to an iOS
device”on page 18.
3. This stereo,24-bit S/PDIF digital
output mirrors the Main Out.
4. This eighth-inch“stereo mini”jack
serves as an alternative input for
Line Inputs 3-4.For example,you
can plug in an iPod or CD player
here,instead of using the quarter-
inch jacks to the right.
DO NOT
plug a cable into this mini jack at
the same time as the quarter-inch
jacks.
To avoid ground loop
noise
,don’t connect a device with
another power source (such as an
iPod connected to a computer).
5. These two analog inputs are
balanced TRS (tip/ring/sleeve)
quarter-inch connectors that can
also accept an unbalanced plug.
These inputs (3-4) do not have mic
pre-amps,so they are best used
for synthesizers,drum machines,
effects processors,and other
devices with line level signals
(either -10 or +4).The CueMix FX
software lets you adjust the input
level for recording.If you use these
quarter inch jacks,DO NOT plug a
cable in to the stereo mini jack.
6. This eighth-inch“stereo mini”jack
serves as a stereo line level analog
output that is completely
independent from the Main Out
(to the right).
7. These two balanced,quarter-inch
jacks serve as the MicroBook’s
main outputs.You can connect
them to a set of powered studio
monitors.To control volume,push
the VOL knob on the top repeat-
edly until the speaker LED is lit.You
can hear the output of your audio
software on these Main Outs,and
also use CueMix FX to monitor live
MicroBook inputs.

I/O format.You can record and play back
16-bit or 24-bit audio files at any
supported sample rate via any of the
MicroBook’s inputs and outputs.
CueMix FX mixing and effects
All MicroBook inputs and outputs can be
routed to the on-board CueMix FX 8-bus
(four stereo) digital mixer driven by
hardware-based DSP. The mixer allows
you to apply no-latency EQ and
dynamics processing to inputs, outputs
or busses directly in the MicroBook
hardware, independent of the computer.
Input signals to the computer can be
recorded wet, dry, or dry with a wet
monitor mix (for musicians during
recording, for example).
Effects include parametric EQ and
compression/limiting. Standard
compression provides conventional
threshold, ratio, attack, release, trim, and
knee controls. The 7-band parametric
EQ is modeled after British analog
console EQs, featuring four filter styles
(gain/Q profiles) to effectively cover a
wide range of audio material. Low-pass
and high-pass filters are also supplied
with slopes that range from 6 to 36 dB.
The MicroBook’s flexible effects
architecture allows you to apply EQ and
compression on every input and output.

INSTALLING THE MICROBOOK SOFTWARE 15
3Installing the MicroBook
Software
NO SOFTWARE INSTALLATION FOR
iOS DEVICES
The MicroBook IIc is a USB audio class
compliant device, so it can be used as a
simple 4-input, 6-output audio interface
(with no mixing or processing features)
for iPad and other iOS devices. No
software installation is required. Just
connect the MicroBook to your iOS
device as explained in “Connecting to an
iOS device” on page 18, and access it in

system requirements for your MOTU
interface.If so,the installer proceeds with
the Mac OS X installation. Drivers are
installed, along with the CueMix FX
application.
Class compliant operation under OS X
The MicroBook IIc is a USB audio class
compliant device, so OS X will recognize
it as a simple 4-input, 6-output audio
interface, even without the MicroBook
drivers installed. When operating in this
mode, the MicroBook can be used as a
simple audio interface (with no mixing or
processing) with any Mac audio software.
However,it is still recommended that you
run the software installer, so that you can
take full advantage of all the professional
features offered by the MicroBook.
WINDOWS SOFTWARE
INSTALLATION
Before you connect the MicroBook audio
interface to your PC and turn it on, it is
best to install the software drivers first.
This ensures that all the MicroBook
