LOW BATTERY
When the battery level approach to be low, all the (turned ON) LEDs will fast blink every “2” sec. When the
battery is at a very low level the audio out is muted and the LED continuously blinks.
Setting input gain on iRig Pre HD
When talking or singing into your microphone, check the audio level/status LED on iRig Pre HD.
• If the LED is alternating between BLUE and GREEN, or is always GREEN, you should increase the iRig Pre
HD input gain by rotating the GAIN control clockwise.
• If the LED sometimes flashes RED, you should decrease the iRig Pre HD 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.

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. 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 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.
Stand adapter
You can fix iRig Pre HD to any microphone stand or pole via the included velcro strip.
Troubleshooting
Sound is distorted.
You’re probably overloading the input. Check that the input gain on iRig Pre HD 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 Pre HD 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 Pre HD” as the audio 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 Pre HD’s battery compartment.
I can’t get any sound from my condenser microphone.
Your microphone may need phantom power. Turn phantom power on by moving the iRig Pre HD switch to the
ON position and check that the Phantom LED has turned on.
