I just purchased a Bogen TPU-35B paging amplifier and a Bogen WMT1-A transformer for my current Bogen TAMB2 paging access relay module and will be getting rid of my TOA BG1015 paging amplifier in hopes I can make everything work out with the same type of equipment being the same brand. I also have a gentleman helping me setting up the paging system and my Cisco VoIP phone system. Once I get all the paging parts and equipment which should be in a couple days, I will make a drawing if needed if I still need help. Otherwise, I’m hoping the gentleman will be able to take care of my problems I’m having. Thanks much in advance!
