Which frequency version should I purchase?

We suggest K4E as this is the primary UK version that covers channel 38. Note that a licence is required to operate wireless microphones in channel 38.

Available for use with a channel 38 licence now and beyond 2012.

K4E: Eleven radio microphones simultaneously in TV channel 38 (groups 6-11)or forty-five radio microphones simultaneously in TV channels 38-45 (groups 1-3).

* Licence free now and beyond 2012: Up to four UHF-R® systems can be used simultaneously using frequency version R9 without a licence. Use group 45.
