I'm delighted to be able to offer a Bose PA System with a Seinhisser Wireless Microphone to my packages which makes me self-contained. I find that I go to lots of different venues with all types of pa systems with microphones which sometimes can be good and most of the time be very poor. So I decided to include the use of mine which is top-of-the-range equipment. you will never have the moment that you can't hear the person speaking or the Microphone not working!
