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 Mic Cast HD. This delay, called latency, is caused by the computer processing
required to convert and record audio. Since this delay can be distracting, iRig Mic Cast HD 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 the Headphone output. 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.
Troubleshooting
My recording is distorted.
Check that the input level on iRig Mic Cast HD has been set properly. If the red LED is lighting when you talk or
sing decrease the input level as described in this guide.
I can’t hear anything from the headphone output.
Check that the app you’re using allows for audio-through from input to output. If not, you can activate the direct
monitor feature on iRig Mic Cast HD.
Random noises appear during the recording.
This may be due to RF interferences: If the connected device sends or receives data wirelessly while recording,
noise could occur in the recording. Although the shells of iRig Mic Cast HD have a layer of conductive paint that
shields most of radio interferences, some unwanted noises could happen. We suggest to turn on Airplane mode
and connect to Wi-Fi for streaming. If the noise persists, we suggest to disable also the Wi-Fi.
The iRig Mic Cast HD status LED is always dark blue and I don’t get any sound.
In order for iRig Mic Cast 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 digital audio input from the Lightning dock connector.
Mac: Be sure you have set “iRig Mic Cast HD” as the audio input device on the audio app you are using.
Is the iRig Mic Cast HD compatible with Android devices?
Yes, the iRig Mic Cast HD is compatible with Android devices running Android 5 or later and with USB digital
audio capabilities. Micro-USB-OTG to Micro-USB cable included.
