Have a PagePac 20 with three speaker horns working currently. Added a speaker (a Bogen, not the Avaya) 70V but discovered that they used the port J5 for Voice Coil not the 70V as I originally concluded. Since using the voice coil circuitry, I understand I need an amplified horn with a seperate power supply. However, in looking at the installation of the three other Avay horns, I see no power supply attached for them. What's going on? Did I miss something? The other three horns are 30 Watt horns made by Avaya.

Thanks,

If you have horns not speakers on the voice coil output of the PagePac and they are working, then the horns have to be the 1 watt voice coil horns. The voice coil output will drive a voicecoil speaker up the the rated 20 watts. 3 Horns = 3 watts plus a watt or so of loss in the cabling. 70 volt horns and speakers have a tranformer built in, voice coil units do not. Hook your 70 volt horn up to the 70 volt output and set the tap setting to 1,2 or 3 or get yourself a voicecoil horn or speaker.

The Page Pac 20 is an example of a product that has been so "dumbed down" that an idiot can install it. Both the voice coil and 70 volt outputs are RCA jacks. Why in Gods name would anybody use RCA cables for speakers and where in the world would you get pre-made cables in the required lengths?

Point is ignore the fact that the outputs are RCAs, they don't indicate that you need amplified speakers.

For what it's worth you can get a copy of the installation documentation from the Avaya website. Their instructions for determining how many horns and speakers is so obtuse as to be worthless. They don't mention it but I see no reason you can't use the 70 volt output also. Set your new horn at something like 4 watts and see how it sounds.
