Page Pac

[techguy137]

I have a client that currently has a lucent/valcom Page Pac D100. It isa talkback system with 24 zones. I have limped this system along for years but it's now time to replace it as parts are difficult to find. I am looking at a Bogen TPU100 as a replacement. The client doesn't want the talkback function anymore. There are approximately 40 speakers on this system. 70v 45 ohm speakers.
My question is is the 100 watt unit going to be big enough? The old page pac is 100 watts so I am thinking so. BTW there are a mis mash of speakers attached to this. They are mostly valcom speakers. there are some bogen 8" ones. Valcom Ptech & valcom 2x2 tile speakers.
Any insight would be helpfull
Thank you

I think you must have the ohms/speaker incorrect. Typical speaker ratings (25v, 70V, 100v system, etc.) are often 8 ohms although other ratings are possible (4ohms or 16 ohms). Many paging speakers allow for 'tapping' at different wattage settings (e.g. 2.5w or 5w) in order to control the local volume output of the speaker, or they may have a volume control that accomplishes the same thing. The Valcom speakers I deal with have the volume control 'pot' (potentiometer) option. Those comments aside, if the current system has been and is working adequately using a 70v, 100w rated amplifier then a similar 70v, 100w rated amplifier should also work. The key is to keep the total wattage of all speakers connected to a single amplifier below the rating of the amplifier. If that isn't possible then multiple amplifiers (the situation in my facility) must be utilized to prevent overloading a single amp.
