Current setup: Phone system connects to TEL Lugs on Amp for Paging. I have a program to play bell sound to notify for break, lunch, start and end of shift. I tried hooking to the music input of the amp, it works but has a constaint buzz in pa. The TEL input lugs of the amp are for 600-ohm, Dry Loop, Balanced input. I wood like to connect to here so signal will replicate to all buildings (Each building(3) has it's own amp, PA system from Phone connects to all amps). I was thinking i need a Sound card with a "Line-Out", just Not sure? Is the Line out on a Sound card a Low Z signal? (Not sure what that means, was told that i needed that). Is there a better solutions out there? Please Help!
