8373 Zone Paging Adapter
Advance Information
IP Paging Adapter for Traditional Analog
Amplifiers with Zone Control
The 8373 is a PoE IP Paging Adapter for integrating
existing and traditional zoned paging solutions into a
VoIP environment, whether premise or hosted. Features
include G.722 wideband support with isolated and
balanced line output for optimum clarity and intelligibility
without hum or noise.
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
To the network side, the 8373 is a SIP endpoint for
easy integration with an IP telephone system and easily
configured using the intuitive web interface or provisioning
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.
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.
Multicast capability allows scalability for multiple amplifiers
as well as integration with Algo IP speakers in zoned and
large scale applications.
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
