The MIPRO's MA101ACT is a economical and easy-to-use wall-mounted wireless megaphone that produces crisp, strong sound. This powered speaker features built-in 45 Watt (rms) high-efficiency amplifier, high-fidelity full-range speaker, detachable AC switching power supply, and detachable receiver module with world's first ACT (Automatic Channel Targeting) function that allows 97 selectable UHF channels and automatic set up transmitter frequency quickly.
The amplifier can be installed on the walls or in the ceiling. Users can use the same personal microphone transmitter to turn on/off amplifiers and modify volume after the amplifiers have been fitted and the built-in receiver modules have been set for non-interference operation. An external lavaliere and headworn microphone, as well as other audio sources, can be connected to the transmitter through a tiny phone-jack input, in addition to being a handheld microphone. The transmitter is also equipped with rechargeable batteries, allowing users to simply return it to the authorised charger after usage.
