The WMS40 Mini Sport Set is versatile and easy to use. It consists of a receiver, pocket transmitter and headband microphone. The operation of the WMS40 Mini Instrumental Set requires no prior knowledge â simply unpack, switch on and off you go. The radio system is free of registration and charges (ISM frequency band). The receiver has a robust metal casing and is very compact. On the front, there are control LEDs for the operating state (On/Off), the radio reception and overmodulation. The level of the 6.3 mm jack output can be set via the volume control. HDAP technology (High Definition Audio Performance) guarantees high sound quality and a secure transmission of the audio signal. The pocket transmitter is especially small and light. With only one AA battery, it is ready for use for up to 30 hours. The input sensitivity for the respective connected microphone or instrument can be adjusted continuously directly on the pocket transmitter. The over-the-head microphone is lightweight and unobtrusive. It is so comfortable that you can wear it for a long time, whether in presentations or during sports. The voice is transmitted with high speech intelligibility and thus also works well in loud surroundings.A power supply unit and a battery are included in the delivery.This text is machine translated.
