Description:
The digital UHF series of wireless headsets, based on pi/4-DQPSK modulation and employing digital UHF transmission technology, boasts a low bit error rate and stable transmission. Compared to mainstream 2.4G/analog modulation wireless headsets in the industry, it offers advantages such as strong anti-interference capabilities, ID code pilot technology to prevent crosstalk, and frequency sweeping to avoid interference. Specifically designed for professional scenarios demanding stability and clarity, it is widely applicable to schools, conferences, training sessions, and other similar settings.
