Description
Powerful rack-mount amplifier that connects modern SIP phone systems to your existing 25V or 70V constant-voltage speakers.
If you're running a school, warehouse, manufacturing plant, or any large building with overhead paging speakers already wired in, the CyberData 011598 lets you move to a modern VoIP phone system without tearing out and replacing all those speakers. This hybrid amplifier gives you four independent analog zones plus full multicast capability, so you can keep your proven 25V/70V speakers and horns while gaining all the benefits of SIP paging, scheduled bells, background music, and night ringer functions.
Perfect for facilities managers and IT teams who need scalable, reliable overhead paging that works with both legacy analog infrastructure and today's cloud or on-premise VoIP platforms.
The Telecom Spot Expert Review
We've deployed dozens of CyberData paging solutions over the years, and the new 011598 is a game-changer for customers who aren't ready to go 100% IP endpoints. The four-zone design means one box can cover an entire floor or multiple buildings with separate paging groups – something the previous single-output models couldn't do without adding extra amplifiers.
Pros
- Four independent analog outputs – up to 392W continuous in 70V mode
- Built-in bell scheduler and background music input
- Full SIP + multicast support (including Poly channel paging)
- Rack-mount with clear LCD for on-site diagnostics
- Five-year warranty and excellent CyberData technical support
Cons
- Requires careful wattage calculation to avoid overloading zones
- No native InformaCast (see 011599 if you need it)
