Compact and easy to set up UHF wireless microphone set with 2 handheld transmitters and single USB receiver. The receiver simply plugs into a USB power supply or USB port for power and outputs a mix of both microphones 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 transmitters are powered by 2 x AA batteries each and operate on 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 2-person presentations, conferences and vocal performers.Power supply[tab]USB 5V, 1A (receiver), 2 x AA batteries (each transmitter)[br]Frequency response[tab]50Hz - 15kHz[br]Capsule[tab]Dynamic cardioid (each handheld)[br]Output connection[tab]3.5mm mono jack[br]Wireless range[tab]Up to 50m[br]Dimensions : transmitter[tab]240 x 50mmØ (each)[br]Weight : transmitter[tab]178g (each - no battery)[br]Carrier frequencies[tab]863.2MHz + 864.8MHz[br]Dimensions : receiver[tab]80 x 34 x 15mm[br]Weight : receiver[tab]25g
