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: 50Hz - 15kHzvbCrLfPower supply: USB 5V, 1A (receiver), 2 x AA batteries (transmitter)vbCrLfDimensions : transmitter: 240 x 50mmØvbCrLfWeight : transmitter: 178g (no battery)vbCrLfDimensions : receiver: 80 x 23 x 13mmvbCrLfWeight : receiver: 17gvbCrLfOutput connection: 3.5mm mono jackvbCrLfWireless range: Up to 50mvbCrLfCapsule: Dynamic cardioidCarrier frequency: 864.8MHz
