We know you've got questions, and if you're brave enough to ask the world for answers, then here's the outlet to do so. This week's Ask Engadget inquiry is from Wes, who needs to ensure that Delta Tau Chi don't start interfering with his band practice sessions. If you're looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.
"I'm a university band director, and I need a WiFi stereo receiver for our rehearsal space. The problem is, that it would have to join the same network that the students and faculty all share. I want to be able to Airplay music and related apps (like a metronome) through the setup, but I'm worried that any student can connect and mess with it. I can't seem to find a receiver that requires a separate password to connect to it, so I could really use some help! Thanks, Wes"
Wes, we'll help you on one condition: the next time you're directing a half-time show, the band has to stand in the shape of the Engadget logo. Deal? Good.It's very easy to set an AirPlay access code onto an Apple TV. That way, if anyone wants to start pushing tunes (or apps) to your sound system, you have to enter a four-digit code of your choosing.You can also control permissions on other AirPlay devices like the Sony STR-DN1030, but there's a limit of 20 devices, and it's a little bit fiddly.
Of course, this wouldn't be Ask Engadget without some audience participation, so, dear audience, participate! Share your knowledge, tell us tales and spread some love this weekend -- but only if said love is related to the world of AirPlay passwords.
