How can I set up a PA system with music and timed announcements through the day?

Episode 987 (17:12)

David from Kansas City, MO

David works for a zoo and wants to set up music that would play through the PA with announcements that would be timed throughout the day. He wants it to be automted. Leo says it's an easy thing to do. An iPod Touch or a Google Nexus 7 with an Alarm app could do it. Most alarm apps will allow him to create music playlists. He'll just have to be sure alarms don't turn off.

In the chatroom, Effin_dunn worked at the LA Zoo and they did something similar. So Leo recommends they contact the LA Zoo and collaborate on a solution.
