Troubleshooting
Sound is distorted.
You’re probably overloading the input. Check that the input gain on iRig Pro DUO 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 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 30-pin or 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’s battery compartment, or that you’ve
connected iRig Pro DUO to an external power supply.

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

When I connect iRig Pro DUO 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 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 in order to use it with this USB host.
I have connected iRig Pro DUO to my iPhone or iPad but it doesnt’ turn ON.
iRig Pro DUO only works with AA batteries when connected to iOS devices.
I use iRig Pro DUO onstage and get buzzes and noises when connected to a PA system or main mixer.
Always connect iRig Pro DUO 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 and two condenser microphones and the iRig
Pro DUO’s battery life is very short under these conditions.
Use rechargeable high-performance AA batteries from 1,900 mA/h up. iRig Pro DUO will last approx 3.5 hours in
these recording conditions.
