Selectable frequencies are another nice feature. Back in the old days, your wireless system was on a fi xed frequency. That was fi ne as long as there weren’t any other wireless systems at the location. If there were, you could experience anything from fuzzy audio to picking up someone else’s microphone. Many of today’s systems offer a choice of operating frequencies – anything from two to over 1,000. Basic wireless rigs offer a simple A/B switch on the transmitter and receiver. This gives you two frequency options and provides some basic insurance against intruding signals. Better systems provide four or more frequencies and many allow you to custom tune your system to any available fre- metropolitan areas, theatres and churches where many signals may live at the same location. The most sophisticated systems actually scan the location and set the frequencies for you based on available bands. This is an expensive option, but can save a great deal of time and grief.
