AmericanDJ Airstream IR

Airstream IR turns an iPhone or iPad into the remote for ADJ's infrared-controlled fixtures. The free Airstream IR app from the App Store drives a small transmitter that plugs into the phone, and from there you get sound-active mode, blackout and standby, full brightness, fades, dimming, strobe, gobo selection and colour changes - the same commands the fixture's own IR handset sends, from the phone already in your pocket.

Range is roughly 15 to 20 feet, line of sight, so it is a hand-held tool for a small room rather than a booth-to-stage control link. It covers the Inno Pocket family (Spot, Pearl, Scan, Roll, Wash, Fusion, Spot Twins, Z4 and Beam Q4) plus the Gobo Projector IR, Ikon IR, H2O IR, H2O DMX IR, Ricochet and ON-X. One practical note from ADJ: turn the phone's headphone volume all the way up, because the app drives the transmitter through that output.
