What’s the difference between the Switched and Unswitched external speaker jacks featured in the PowerPro™ and PowerPro SD PA systems?
When the external companion/support speaker is connected to the PowerPro™ or PowerPro SD PA system through the Switched speaker jack, the audio is heard through only the companion/support speaker. When the external companion/support speaker is connected to the PA system through the Unswitched speaker jack, the audio can be heard both through the main PA system and the companion/support speaker.
