Switch Sound Between PA Speakers
15th in a series about how to use (portable) PA gear.
Sometimes everyone needs a little bit of help from a friend, and PA systems are no different. Just as one speaker can be powerful enough on its own for certain occasions, connecting multiple speakers can provide a force of sound to be reckoned with for others.
When you have a PowerPro™ (PA919 or PA919SD) at your disposal, your portable audio needs are covered. With both you can play music from your choice of CD, cassette, SD card or MP3 player, which links up to the speaker’s RCA line input. Or use a wired or wireless microphone to make your announcements to an audience of varying size. What these three speakers have in common is that they are all UHF speakers that can communicate with one another through one of their 16 frequency channels.

But what if you want to add even more power and a non-powered support speaker that lacks the 16-channel UHF capability is the only one available? What then? Or you need to only play sound from that speaker but don’t have a media source. Well the solution is simple. You can connect the non-powered PA919SP to any of aforementioned portable speakers using a ¼” to ¼” (SC-50) cable. Connect one end to the ¼” speaker in jack on the PA919SP and the other end into one of the ¼” switched or unswitched speaker out jacks.
The purpose of the two different speaker out jacks is so you have the flexibility of using the main unit in conjunction with the PA919SP or having the main unit serve as your media source with only the PA919SP projecting sound. So if you are playing music through one of the UHF speakers and only want the sound to come out of the PA919SP speaker you would connect the cable to the switched speaker out jack. Hook it up to the unswitched jack to be sure that the sound comes out of both the main unit and the PA919SP.
