We are looking into purchasing either a ATV or AE to use at a school for streaming of audio during sporting events. I am trying to figure out which one would work better. We will be playing audio from an iPad inside the gymnasium. The new device will be located in the corner of the gym in a ticketbooth where the audio rack is. The analog on the AX and optical on ATV does not matter. We can use both of those. Any insight would be appreciated.
