About this app

For use with transmitters by Lectrosonics, Comtek, Sennheiser, Zaxcom, and more.

FreqFinder calculates the intermodulation products of user entered transmitter channels and then suggests options of channels that will be compatible with user transmitters already in use.

Recommended for use with 12-24 transmitter systems depending on the processing power of your device and the spread of your transmitters.

US Customers: TVDB in-app purchase now available. Accesses the FCC database for local TV broadcast towers and estimates the field strength at your location for better channel selection.
Avoid intermodulation interference on all of your popular audio transmitters!
