Battery-powered operation with UHF transmission

The unit runs on an internal battery charged via USB Type-C and transmits on a single UHF channel with power-on sync for immediate use. Low-latency wireless delivery keeps voice natural at distances up to 65ft while the 15W amplifier covers areas up to 1000. No fan or active cooling is mentioned in the specifications.

15W output and 65ft wireless range

Questions about this item

How do I pair the headset microphone with the amplifier, and what step causes the most trouble?

Turn both units on; power-on sync links them automatically on the UHF channel. The step users miss is waiting a few seconds after power-up before speaking, otherwise the first words drop out.

Which part will need replacement first with daily classroom use?

The internal rechargeable cell powers the 15 W output; after several hundred charge cycles its run-time shortens and the pack must be swapped.

What limits continuous operation during a long lecture or tour?

Battery capacity caps sustained use; at full 15 W output the amplifier runs roughly 8 hours before the cell needs recharging via USB Type-C.
