A compact and convenient UHF wireless microphone set with 2 x handheld transmitters and single plug-in receiver. The receiver is self-powered and rechargeable via USB, delivering a mix of both microphones to its single 6.3mm mono plug. The handheld transmitters are powered by 2 x AA batteries each and operate on 2 fixed UK/EU licence-free UHF frequencies. This system avoids the need for a free-standing or rack-mounted receiver and is a cost-effective and easy-to-use solution for 2-person presentations, conferences and vocal performers.
