The ETS PA922 Smartphone Audio Balun Cable for iPhone mates professional XLR microphones with the 3.5mm TRRS jack of a smartphone's audio input jack, allowing software on the iPhone to record professional quality audio. The PA922 also includes a 3.5mm female jack for monitoring the incoming audio as well as "listen-in" software.
Cables feature built-in ETS Balanced Line technology. The PA922 includes a 3.5mm TRRS mini-plug with 18" tangle free flat cable plus a 3.5mm jack with 6" pigtail to Female XLR. The PA922 is similar to the PA921 with an additional 3.5mm jack on a 6-inch pigtail. This pigtail audio plug provides an audio source so one can hear what is being recorded simultaneously. Software is provided by ETS with purchase of each PA922 to take advantage of the audio monitoring tap and "listen-in". This software works on Apple iPhone smartphones ONLY.
