Compact and easy to set up UHF wireless microphone set with a handheld transmitter and USB receiver. The receiver simply plugs into a USB power supply or USB port for power and outputs to a 3.5mm jack socket. A plug-through USB connection is provided on the receiver to allow the USB port to continue to be used for connection to media or other USB devices (e.g. for a USB flash mp3 player port). The handheld transmitter is powered by 2 x AA batteries and operates in one of 2 UK/EU licence-free UHF frequencies. This system avoids the need for a free-standing or rack-mounted receiver and can operate from a standard USB power supply for ultimate convenience. A cost-effective and easy-to-use solution for presentations, conferences and vocal performers.Frequency response[tab]50Hz - 15kHz[br]Power supply[tab]USB 5V, 1A (receiver), 2 x AA batteries (transmitter)[br]Dimensions : transmitter[tab]240 x 50mmØ[br]Weight : transmitter[tab]178g (no battery)[br]Dimensions : receiver[tab]80 x 23 x 13mm[br]Weight : receiver[tab]17g[br]Output connection[tab]3.5mm mono jack[br]Wireless range[tab]Up to 50m[br]Capsule[tab]Dynamic cardioid Carrier frequency[tab]863.2MHz
