The HR-31S is a premium true diversity system in the UHF spectrum that can fully exploit its strengths, in particular in connection with the RWW software. The transmission takes place either in the professional switchable band 731-790 MHz or in the license-free range 823-832 MHz. The other features also convince: quick setup via infrared andan exceptionally long service life of the transmitter from up to 15 hours on just one set of batteries.
