6 Low Battery
When the battery level approach to be low, the INPUT LED will fast blink red.
Troubleshooting
Sound is distorted.
You’re probably overloading the input. Check that the input gain on iRig Keys 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 Keys 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 Keys I/O” as the audio or MIDI input device on the audio app you are using.
Phantom power doesn’t turn ON when connected to an iOS device.
Check that you have inserted working AA batteries in iRig Keys I/O’s battery compartment, or that you’ve
connected iRig Keys I/O to the 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 Keys I/O botton to the
ON position.
