Can 2 or 3 of these rack units be used at the same time? Have a school play where at least 16 mices will be needed.
Asked by: Eddie
You can use multiple Nady 8W-1KU wireless systems at the same time. The system's 1000 user-selectable frequencies with auto-scan enable you to easily locate clear operating frequencies for each of the eight independent receivers, so it should be possible to use two or three systems simultaneously.
