The transmitters both microphone and bodypack are equipped with an easytoread LCD display and an IR infrared receiver port for synchronizing the output signal with the receiver. The top of the bodypack transmitter has an antenna for wireless communication and a signal socket. In the center of the handle of each handheld microphone is a power switch and LCD display showing the transmitters operating frequency and battery level. It also houses a high and low frequency switch, which allows us to make subtle adjustments to the tone of the sound collected by the microphone. The headset microphone has a comfortable, lightweight and almost invisible headband made of metal rod, which is relatively elastic and properly shaped. The transducer itself is placed on the socalled gooseneck. Thanks to this, its position can be perfectly adjusted to individual needs. Comfortable, long cable allows freedom of movement even for tall people. The devices are powered by two AA batteries which allow the microphones to operate for up to 8 hours! The UHF receiver has 2 XLR output channels A and B and a 14 jack output. There are 4 separate control panels on the front that operate individual microphones. Using these, we can pair the devices with each other by sending the correct transmitter frequency via infrared to a specific panel. The microphones are ready for operation, and through the receiver we can control their volume and channel functions. The wide frequency range and high data transmission speed allow the microphones to work without interference.
