The following troubleshooting topics are presented to resolve issues when using Apogeeʼs MiC with Apple iOS devices and Macintosh computers.

iOS Device Trouble Shooting

No audio input with GarageBand and MiC Symptoms - If you are using iOS 4 and connect an Apogee MiC, GarageBand may display a message to connect a microphone or other input device. If you press record, you may see a message that the device does not have an audio input and that you cannot record. Resolution - This issue is resolved in iOS 5 - see Apple support article here - http:// support.apple.com/kb/TS4129. MiC not initialized (no blue LED) after a cold start of the iOS device On iOS devices updated to iOS 5, MiC may not be initialized after starting the iOS device from a powered-down state. In this case, MiCʼs LED indicator is not illuminated blue (as should be the case). Simply disconnect then re-connect MiC, or connect MiC after the iOS device has completed its start- up sequence. After sleeping then waking an iOS device while GarageBand is open, audio may become distorted Symptoms - After an iOS device goes through a Sleep/Wake cycle, audio may become distorted. Resolution - Quit all audio apps (see clicks and pops below) and re-launch GarageBand No input after connecting Apple headphones with mic Symptoms - After connecting Apple iPhone headphones, or other headphone equipped with a built-in mic, audio apps donʼt accept input from MiC. Resolution - iOS devices accept audio input from the most recently connected peripheral, in this case the built-in mic. To re-establish input from MiC, disconnect and re-connect MiC. Clicks and Pops on iOS devices Tip - When experiencing clicks and pops on iOS devices, try closing all apps and re-starting the audio app with these steps: 1) Press the Home button to return to the Home screen 2) Double-tap the Home button to display recent apps 3) Tap and hold the affected app until the red minus appears 4) Tap the red minus to quit the app. GarageBand and Airplay - Bluetooth - HDMI equipped output devices GarageBand 1.01 and higher offers the capability to output to external output devices equipped, including Airplay, Bluetooth and HDMI-equipped media devices. When using any of these devices there is no support of audio input, including MiC. See the Apple Support article which describes this functionality here: http://support.apple.com/kb/HT4622. Latency Weʼve measured latency from MiC through GarageBand iPad to iPad headphone output to be 23ms. We havenʼt found instances of latency inconsistency, though there are reports from the field indicating that latency can increase.

MacIntosh Troubleshooting

Long latency after putting the Mac to Sleep - OS X 10.6.8 Symptoms - After the Mac goes through a Sleep/Wake cycle, latency through MiC is excessively long. Resolution - This is fixed in OS X 10.7 Clicks and Pops on the Mac Tip - When experiencing clicks and pops on a Mac, try raising the buffer size in the audio app. In Logic, for example, choose Logic Pro > Preferences > Audio, click the Devices tab, then the Core Audio tab, and set the I/O Buffer Size to the next highest number.
