Using iPad as a PA system

[marcelojmonteiro]

If I plug an iRig Mic Lav into an iPad, can I use its speakers to project my voice in real time to students in a small classroom?

[Ryan_IK]

Yes, as long as your speakers are connected to the headphone output on your iRig Mic Lav.

And can it work in background, while I use another app, like Powerpoint?

[Ryan_IK]

Yes, when using an IK Multimedia app like iRig Recorder 3 LE, VocaLive CS, or EZ Voice. These apps offer a ''Background Audio" option in the Menu -> Settings.
