Adjust audio and visual settings on iPad
You can adjust audio and visual settings such as mono audio, audio balance, and LED Flash for Alerts.
Adjust the volume balance and mono audio
Go to Settings
> Accessibility > Audio/Visual.
Adjust any of the following:
Mono Audio: Combine the left and right channels into a mono signal played on both channels.
Balance: Drag the Left Right Stereo Balance slider.
Flash the LED for alerts
On an iPad with flash, if you can’t hear the sounds that announce incoming calls and other alerts, iPad can flash its LED (next to the camera lens on the back of iPad). The LED flashes only if iPad is locked.
Tip: LED Flash for Alerts is a useful feature for anyone who might miss the tones associated with calls and other alerts in a noisy environment.
Go to Settings
> Accessibility > Audio/Visual, then turn on LED Flash for Alerts.
To prevent LED flashes when iPad is in silent mode, turn off Flash on Silent.
