CONNECTION DIAGRAM
Notes:
y When recording a guitar or bass with an active pickup, set the iO2 EXPRESS's MIC/LINE / GUITAR
SWITCH to "MIC/LINE." If your instrument uses a passive pickup, set the switch to "GUITAR."
y Do not use the MIC INPUT and GUITAR/LINE INPUT at the same time on one channel. This may
overload the channel and cause distortion.
y Plug the iO2 EXPRESS directly into your computer, and avoid using a USB hub. Hubs can interfere with
the iO2 EXPRESS's audio and MIDI timing signals.
y To reduce electrical hum at high gain settings, keep the iO2 EXPRESS's power supply away from your
guitar cable and the iO2 EXPRESS's channel inputs.

instructions below for your computer's operating system:
WINDOWS 7:
1. Use the included cable to connect the iO2 EXPRESS to your
computer.
2. Go to Start Menu Control Panel Hardware and
Sound Sound.

4. Close the window.
Be sure your audio software program is
set up to receive audio via the iO2
EXPRESS. This can usually be done in
your software's "Preferences" or
"Device Setup." Please consult your
software manual for more information.
* If you have other USB audio devices
connected to your computer, which may
have identical names, you may need to
try selecting each one until the iO2
EXPRESS is recognized.
If you experience too much latency
after adjusting your software latency
settings, we recommend the free
ASIO4ALL (Audio Stream Input/Output)
driver for PC at www.asio4all.com
.
ASIO drivers generally perform better
and with lower latency since they create
a more efficient communication
between audio devices and software.

FEATURES
1. USB PORT – Use
the included cable to
connect the iO2
EXPRESS to a
computer. iO2
EXPRESS requires a
USB 1.1 or higher
(e.g. USB 2.0)
connection.
2. MAIN OUT – Use
standard 1/4" cables
to connect this
output to a speaker
or amplifier system.
The level of this
output is controlled
by the MAIN VOL
knob.
3. MIDI IN – Use a
standard five-pin
MIDI cable to
connect this input to
the MIDI OUT of an
external MIDI device.
4. MIDI OUT – Use a
standard five-pin MIDI cable to connect this output to the MIDI IN of an external MIDI device.
5. PHANTOM POWER LED – Lights up when phantom power is engaged.
6. MIDI OUT LED – Flashes whenever MIDI data is sent out of the iO2 EXPRESS.
7. MIDI IN LED – Flashes whenever MIDI data is received from an external MIDI controller.
8. USB LED – Lights up when a USB connection has been established with your computer.
9. LED METERS – Monitors the audio level of the MAIN OUT.
10. MIC INPUT – Connect a microphone to this input with an XLR
cable.
11. GUITAR / LINE INPUT – Connect a line-level device or guitar
to this input with a 1/4" cable.
12. MIC/LINE / GUITAR SWITCH – When this switch is in the
"GUITAR" position, the channel will serve as a highimpedance input for connecting guitar or bass instruments.
When the switch is in the "MIC/LINE" position, the channel will accept mic or line-level signals.
13. GAIN – Adjusts the channel audio pre-fader and pre-EQ gain level.
14. INSERT – The insert jack allows you to insert a compressor, EQ, or any other signal processor in
between the iO2 EXPRESS's preamplifier and A/D converter.
15. PHANTOM POWER SWITCH – This switch activates and deactivates phantom power. When
activated, phantom power supplies +48V to both XLR mic inputs. Please note that most dynamic
microphones do not require phantom power, while most condenser microphones do. Consult your
microphone's documentation to find out whether it needs phantom power.
16. MONO / STEREO – Adjusts the headphone mix for mono or stereo operation.
17. MONITOR MIX – Blend in any amount of zero-latency signal from your inputs with the output of your
computer.

DIAGRAMA DE CONEXIÓN
Notas:
y Cuando grabe una guitarra o bajo con captor activo, ajuste el CONMUTADOR MICROFÓNO/LÍNEA /
GUITARRA de iO2 EXPRESS a "MIC/LINE". Si su instrumento usa un captor pasivo, ajuste el
conmutador a "GUITAR".
y No utilice la ENTRADA DE MICROFONO (Microphone) y la ENTRADA DE GUITARRA / LÍNEA (Guitar /
Line) al mismo tiempo en el mismo canal. Esto puede saturar el canal y causar distorsión.
y Enchufe la iO2 EXPRESS directamente a su computador y evite usar un hub USB. Los hubs pueden
interferir con las señales de sincronización de audio y MIDI de la interfaz iO2 EXPRESS.
y Para reducir el zumbido eléctrico cuando se usan ajustes altos de ganancia, mantenga la fuente de
alimentación de iO2 EXPRESS alejada del cable de su guitarra y de las entradas de los canales del
equipo.
