8373 Zone Paging Adapter

Wideband IP Paging Adapter With Zone Control for Integrating Legacy Analog Amplifiers

The 8373 is a paging adapter for IP enabling zoned analog voice paging systems. The endpoint is a SIP interface to seamlessly bridge an analog paging system to VoIP. Common application environments include schools, hospitals, retail stores, etc.

The 8373 is a PoE IP Zone Paging Adapter for integrating legacy voice paging systems into a hosted or premise UC environment as a third party SIP endpoint. The Adapter eliminates the need for a legacy zone controller, however, the 8373 can also be deployed to add page zones to an existing single zone system. Features include G.722 wideband support with isolated and balanced line output for optimum clarity and intelligibility without hum or noise.

To the network side, the 8373 is a SIP endpoint for easy integration with an IP telephone system. It is configured using the intuitive web interface or provisioning capabilities.

On the paging side, the 8373 provides balanced audio output using both an XLR connector and terminal block for easy connection to an amplifier, along with a dry contact closure if required by the amplifier.

The high voltage audio output of the amplifier is wired back to the 8373 and connected to up to three separate speaker zones using high current internal zone control relays. The zone control relays are activated appropriately prior to paging based on the SIP extension called, multicast IP address received, or keypad input. For scalability, multiple 8373 Paging Adapters can be used to support as many page zones as required from a single amplifier.

Further speech enhancement is provided by automatic level control, choice of frequency masks, and optional speech compression. Output level is compatible with consumer, commercial, and pro-audio amplifiers requiring either -10 dBm, 0 dBm, or +4 dBu line level.

Multicast capability allows scalability for multiple amplifiers as well as integration with any combination of Algo IP speakers/strobes/adapters (e.g. 8128, 8180, 8186, 8188, 8301, 8373) in zoned and large scale applications.
