iRig Pro Duo I/O LEDs

The four LEDs on iRig Pro Duo I/O give you important information about the unit’s operative status. Each status
is indicated by a different color.

Status / Audio level LEDs

For each channel iRig Pro Duo I/O will show the audio signal level and the status of the unit as follow:

• Both LEDs Off: iRig Pro Duo I/O is not connected to any power source.

• Both LEDs Dark blue: iRig Pro Duo I/O is connected and in standby mode.

• Ch. LED Bright blue: iRig Pro Duo I/O is connected and a signal is present at the input of the corresponding

channel.

• Ch. LED Green: The input signal of the corresponding channel is low.

• Ch. LED Orange: The input signal of the corresponding channel is OK.

• Ch. LED Red: The input signal of the corresponding channel is too high.

Phantom and MIDI LEDs

The two upper LEDs show the phantom power and MIDI status.

Phantom LED

• Off: phantom power is OFF

• Flashing Blue: phantom power is powering ON. To avoid audio bumps iRig Pro Duo I/O is muted while

phantom power is turning ON, so it is normal to not hear any signal until this LED turns steady BLUE when
turning on +48V phantom power.

• Steady Blue: phantom power is ON

• Flashing Red: internal AA batteries are LOW! Before iRig Pro Duo I/O shuts down this LED will start blinking.

This means that the battery level is low and it should be replaced as soon as possible.

English

MIDI LED

• Off: iRig Pro Duo I/O is not receiving any MIDI messages.

• Blinking Blue: iRig Pro Duo I/O is transmitting MIDI messages.

• Blinking Red: iRig Pro Duo I/O is receiving MIDI messages.

Direct monitoring

When recording an audio signal into your audio software, there is often a slight delay before it reaches the
outputs of the software and iRig Pro Duo I/O. This delay, called latency, is caused by the computer processing
required to convert and record audio. Since this delay can be distracting, iRig Pro Duo I/O provides a direct
monitoring path from the inputs to the outputs, which is activated by the Direct Monitor switch. When Direct
Monitoring is enabled, the input signal is mixed with the output signal from your audio software and routed
directly to both the Line and Headphone outputs. This lets you hear the “live” inputs without latency. The Direct
Monitor switch has no effect on what is being recorded by your software. When using the Direct Monitor feature,
make sure any software monitoring option for direct (or “low latency”) monitoring is disabled. Disabling low
latency monitoring prevents “double-monitoring” of input audio signals when using the Direct Monitoring feature.
When “double-monitoring” occurs, there will be an increase in volume and an undesirable “phasing” sound. For
more details about its monitoring function, refer to the documentation for your audio software.

Connecting microphones

Always connect microphones to iRig Pro Duo I/O with XLR-to-XLR balanced cables. This will ensure a pristine
and clean performance from your microphone with iRig Pro Duo I/O.

NOTE: In your audio software, select the appropriate iRig Pro Duo I/O input (1 or 2) as the source of the track
you will be recording to. Adjust the channel gain knob until you have a sufficient audio signal without clipping.

12

English

Dynamic microphones

Before connecting dynamic microphones make sure phantom power is turned OFF. Check that the Phantom
Power switch is in the OFF position and that the Phantom LED is turned off.

Condenser microphones

Most condenser microphones require external phantom power. If phantom power is ON, switch it OFF, and
then connect your microphone. Turn phantom power ON only after the microphone is connected. Once it’s
turned ON, check that the phantom power LED has become blue (it will flash for a few seconds before staying
on). If the LED doesn’t turn blue, check that working batteries are inserted in the iRig Pro Duo I/O’s battery
compartment on the bottom side, and that an application that is using iRig Pro Duo I/O is open. Phantom power
will NOT turn ON if iRig Pro Duo I/O is in standby (status LED lit up dark blue).

13

English

Ribbon microphones

Before connecting a ribbon microphone, turn OFF phantom power and check the microphone’s operating
instruction manual to see if it requires it. Most ribbon microphones don’t require phantom power, and some can
even be damaged by it. If you’re in doubt just leave it OFF. If the microphone won’t work, check its user manual,
it may need phantom power. Please note that when +48V phantom power is turned on, it works on both
channels simultaneously. It is not possible to turn +48V phantom power on one channel only.

14

English

Connecting instruments

Connect your guitars, basses or any other mono instruments to the instrument inputs on iRig Pro Duo I/O using

an1⁄4”plugunbalanced(TSor“mono”)guitarcord.

IMPORTANT: the instrument input on iRig Pro Duo I/O will NOT work if a cable with balanced (TRS or “stereo”)

1⁄4”plugisused.

NOTE: In your audio software, select the appropriate iRig Pro Duo I/O input (1 or 2) as the source of the track
you will be recording to. Adjust the channel gain knob until you have sufficient audio signal without clipping.

Connecting monitors and headphones

• Connect a pair of active studio monitors or an audio amplifier to the 1/4” Line Output jacks labeled Left­Right. If your monitor inputs or amplifier inputs are the RCA type, use 1/4” to RCA cables or adapters to
make the connection.

• Connect headphones to the 1/8” output jack and adjust its level via the headphone thumbwheel.

MIDI IN/OUT

MIDI IN

• Connect the 2.5mm-to-MIDI cable to the iRig Pro Duo I/O MIDI IN port and to the MIDI OUT port on your
keyboard or controller.

• Open a Core MIDI compatible application on your iOS device or on your computer and set “iRig Pro Duo
I/O” as the MIDI input device.

• When iRig Pro Duo I/O is receiving MIDI messages the MIDI LED will blink blue.

15

English

MIDI OUT

• Connect the 2.5mm-to-MIDI cable to the iRig Pro Duo I/O MIDI OUT port and to the MIDI IN port on, for
example, your sound module.

• Open a Core MIDI compatible application on your iOS device or on your computer.

• When iRig Pro Duo I/O is sending MIDI messages the MIDI LED will blink blue.

Setting input gain on iRig Pro Duo I/O

When talking or singing into your microphone, or when playing your instrument, check the audio level/status
LED of the corresponding channel on iRig Pro Duo I/O.

• If the LED is alternating between BLUE and GREEN, or is always GREEN, you should increase the iRig Pro
Duo I/O input gain by rotating the GAIN control clockwise.

• If the LED sometimes flashes RED, you should decrease the iRig Pro Duo I/O input gain by rotating the
GAIN control counter-clockwise.

• When your gain setting is optimal, the LED should alternate between GREEN and ORANGE while you play
or sing.

Troubleshooting

Sound is distorted.

You’re probably overloading the input. Check that the input gain on iRig Pro Duo I/O is set properly. If the Audio
Level LED is red when you play your instrument or sing or talk into a mic, decrease the input gain as described
in this guide.

I don’t get any sound.

In order for iRig Pro Duo I/O to turn on, a Core Audio-compatible audio app must first be launched on your iOS
device or Mac.

iOS: be sure you are using an app that works with audio input from the Lightning dock connector.

Mac: be sure you have set “iRig Pro Duo” as the audio or MIDI input device on the audio app you are using.

Phantom power doesn’t turn ON.

Check that you have inserted working AA batteries in iRig Pro Duo I/O’s battery compartment, or that you’ve
connected iRig Pro Duo I/O to an external power supply.

I can’t get any sound from my condenser microphone.

Your microphone may need phantom power. Turn phantom power on by moving the iRig Pro Duo I/O switch to
the ON position and check that the Phantom LED has turned on.

I can’t get any sound from my guitar / instrument input.

Duo I/O instrument inputs will be muted.

When I connect iRig Pro Duo I/O to my computer or Android device I get a message that says that this
device needs more power and the USB port will be disabled. How can I use my iRig Pro Duo I/O on my
host device?

This means your USB host device is not capable of providing the necessary current. Please install two AA
batteries in iRig Pro Duo I/O in order to use it with this USB host.

I have connected iRig Pro Duo I/O to my iPhone or iPad but it doesnt’ turn ON.

iRig Pro Duo I/O only works with AA batteries when connected to iOS devices.

I use iRig Pro Duo I/O onstage and get buzzes and noises when connected to a PA system or main
mixer.

Always connect iRig Pro Duo I/O outputs with balanced TRS cables to balanced line inputs. This way your
signal will always be perfectly clear.

I do remote recording with my iPad using iRig Pro Duo I/O and two condenser microphones and the iRig
Pro Duo I/O’s battery life is very short under these conditions.

Use rechargeable high-performance AA batteries from 1,900 mA/h up. iRig Pro Duo I/O will last approx 3.5
hours in these recording conditions.
