III. Wireless Microphone Options  
Many companies manufacture wireless microphone systems. As a resource to help you select a wireless  
microphone system, we have provided links to various manufacturers’ websites, again in alphabetical order.  
This list is by no means complete, but should give you a good sampling of the systems that are available for  
installed room use. Note that a wireless microphone system will normally provide a line level output to  
your Vortex product.  
You should not use a wireless microphone system if security is an important issue. Wireless microphone  
systems operate at radio frequencies, meaning the signal is not restricted to the room contatining the  
microphones and can be picked up by someone with a scanner outside the room.
