I have worked on many Valcom and a few Bogen system, but I'm trying to think which product would best fit the needs and was wondering which way to lean for paging equipment.
What application best fits a Valcom system?
What application best fits a Bogen system?
I can't answer that accurately. Any suggestions? :shrug: | | | | | Joined: Nov 2007 Posts: 492 Member | | OP Member Joined: Nov 2007 Posts: 492 | I found my answer on a previous post. | | | | | Joined: Dec 2007 Posts: 6,688 Likes: 3 Retired Admin |  Retired Admin Joined: Dec 2007 Posts: 6,688 Likes: 3 | See!

Valcom for power supplies, Bogen for paging modules. | | | | | Joined: Apr 2001 Posts: 1,389 Member | | Member Joined: Apr 2001 Posts: 1,389 | If cost is no factor always go with 70v/Bogen(?) system. Much easier to install, add to, troubleshoot, and change. If cost is a factor, 10 horns or less stay with 24v/Valcom(?) system. I have found that 10 horns is typically the break even point. | | | | | Joined: Apr 2001 Posts: 1,389 Member | | Member Joined: Apr 2001 Posts: 1,389 | If cost is no factor always go with 70v/Bogen(?) system.

I have found that 10 horns is typically the break even point. I agree except that there may not even be a cost difference between a 70v system and Valcom that uses powered speakers. With Valcom you have to contend with power supplies and power wiring to each speaker in addition to the audio. And since each speaker contains it's own amplifier they each are a maintenance issue that you don't have with a 70 volt system. I've done 70 volt systems with just two speakers. I don't believe the cost was any more than Valcom and it was a hell of a lot easier. Not that I have anything against Valcom, I just don't see the point. -Hal

What a waste of money! And consistent maintenance issues with failing speakers.
Why use amplified speakers and not a constant-voltage (70 volt) system?
The consultant recommended it. Why? It was all he knew about PA.
I don't mind powered speakers when you're putting in 2 or 3 but even then, like Hal, I still prefer 70 volt. Just remember that unless the amplifier says "class 2 wiring acceptable" (usually the case with 50watts or less) you may have to run conduit or armored cable for a 70volt line.
