WMS 40 Mini2 Dual Vocal Set, ISM2 & ISM3

The AKG WMS40 Mini Dual Wireless Vocal System frees you and a friend from restrictive cable runs. Two performers can benefit from one system thanks to the dual receiver and two included transmitters. True plug and play operation is achieved by the fixed frequency handheld transmitters and included cables turn on your mic and turn the system on - its that simple. Once set up the WMS40 mini delivers the crystal-clear sound quality youd expect from AKG. These dual system mics run on two frequencies 864.375 MHz and 864.850 MHz (Channel 70). They are fixed so cannot be changed to accommodate any other mics that run on those frequencies.
