Overview
Comrex FieldLink PressBox IP Codec (Coming Soon)

Whether you’re calling the big game or broadcasting live from the State Fair, you want your listeners to be right in the middle of the action. FieldLink can connect your audiences with sideline reporters, on-air talent at a street fair or any event where you want to capture the excitement live-to-air.
Instead of using expensive wireless radios for mic and IFB, sideline reporters and talent can use an Android or iOS mobile device with a USB-C audio interface to send and receive audio to and from FieldLink.
Using a directional WiFi Access Point (WAP), contributors can use their smartphones to send and receive high quality, low delay audio using the free Comrex FieldTap app available for iOS and Android. FieldLink has pro-grade audio I/O to deliver sideline audio and allow IFB back to reporters.
- Replaces expensive wireless mic/IFB solutions
- Talent uses their smartphone with a USB-C Mic (no need for extra gear)
- Works with the free Comrex FieldTap app
