The Algo ALGO-8301 IP paging adapter provides a dry page output to a traditional amplifier, offering a seamless bridge from VoIP to a legacy analog voice paging / public address (PA) system. It functions as a scheduler for automated bells, tones, and announcements. A contact closure and music input also feature on the 8301. The paging adapter is a fully compliant 3rd party SIP endpoint.
IP paging adapter for public address (PA) and emergency notification.
Isolated and balanced line output eliminates hum / noise to a traditional amplifier.
Configurable line output supports amplifier input impedance between 600 Ohm and 10 kOhm.
Product Highlights
Ideal for integrating legacy analog public address (PA) systems in education, retail, manufacturing, transport terminals, healthcare, government and other commercial environments.
