Investing in PA gear can be costly and once made, the equipment itself is seldom updated. For many institutions, that's meant using a wired PA when the benefits and flexibility of a wireless mic enable you to do so much more! Our cost-effective Wireless Upgrade kit not only enhances the performance of a wired PA, but can also modernize any outdated 700MHz speaker. The Kit expands a wired PA's usefulness by enabling wireless transmission to it from other audio sources (computers and MP3 players). The transmitter also has a mic input, and with the included headset can be worn either on the hip or around the neck with an available lanyard. Together, they replace the outdated wireless mic with an adjustable range up to 300'! * To upgrade your existing PA, first connect the included headset mic to the transmitter and then match the frequency of the transmitter so it is the same one used on the wireless receiver. The final step is to connect the receiver to the “aux” or “line in” on the existing PA (connecting cable is not included).
