IP Paging System
Paging Over IP Systems

Paging System Summary and Overview

An IP Paging System is a set of audio devices that convert audio to digital signals that are connected to the network. The system also includes software that is used for managing and controlling the audio. The IP Audio system includes speakers, intercoms, audio amplifiers, and management software.

Now it’s easier than ever to install a campus-wide paging or intercom system using your existing Ethernet network. It can be used to provide emergency notification to the campus or specific messages to each room.

Small amplifiers can be placed wherever you have a network drop. No need for long speaker wire connections from a large central amplifier. TalkMaster software runs on your PC, manages the system, and provides digital voice quality sound wherever you need it.


  • PA speaker amplifiers and intercoms can be mounted around the campus indoors or outdoors.
  • High level of reliability. Read more about Reliability and Redundancy
  • Optional if-then tables provide automated responses to triggers
  • Add IP cameras to create a complete surveillance system.
  • Add Bell Commander Software to schedule bells around your organization.
  • Easy installation – Amplifiers and intercoms connect to your Ethernet network

  • Interface to a choice of speakers: analog overhead loudspeakers, wall-mounted, outdoor horn speakers, etc.
  • Fast to deploy, easy to maintain
  • Audio monitoring and intercom capability at any end-point
  • Patent-pending Digital Acoustics® technology


IP Paging Amplifiers

IP Paging Amplifier

The IP7 IP Audio Amplifier module is the core hardware component to Digital Acoustics’ paging solution. You can select the model that meets your exact sound requirements.

The IP7-SE8 uses PoE power from the network and provides up to 8 watts of sound to the attached speakers. It has dual Ethernet ports and supports two-way audio. The IP7-SS20 provides 20 watts while the IP7-SS40 provides up to 40 watts of audio.

The quantity of speakers attached to an amplifier is determined by the sound volume levels required. For example, with a maximum output of 20 watts (using an 8 Ohm speaker), the IP7-SS40 is capable of driving paging horns with sound pressure levels in excess of 120 dB SPL.

This is about the sound of nearby thunder or the sound made by a child screaming. You don’t want to listen to that too long because it will hurt your ears. For these higher output applications, an external power supply is required.

IP Amplifier Models

Model Description
IP7-SE8 8 Watt audio amplifier with audio-in, Dual Ethernet port, PoE, 2-Way Audio.
IP7-SS40 40 Watt audio amplifier, Powered using a power supply, single Ethernet port.


IP Speakers with Built-In Amplifiers

Powered IP Speaker

Powered IP Speakers connect directly to the network are the simplest and quickest to install. No need to run speaker wires, just plug the speaker system into your PoE type network drop and you’re done.

It’s easy. These speakers have built-in amplifiers that provide 8 Watts of power from their PoE connection. The amount of sound (dB) available depends on the type of speaker used. If you need more sound power then you require a separate amplifier and speaker.

TalkMaster Focus is the control and management software for paging and intercom communications. It runs on your Windows computer and allows you to make pages or to communicate to intercoms on your network.  This suite of software is designed to manage intercom and public address operations over IP networks.

There are a number of options. TalkMaster-Solo comes at no charge with your amplifiers or intercoms and allows you to make announcements to all your IP amplifiers and IP intercoms on the network. Talkmaster-Enterprise is a licensed software product, that adds additional capability such as allowing you to make pages from multiple computer consoles, and adds optional modules.


Talkmaster Solo

This full-featured control software comes without charge with any amp or intercom. It allows you to make a page or talk to all your intercoms from a single computer console. It includes a sophisticated fail-over feature so if the first console is not operating it automatically switches to a secondary or even third level computer console. This paging application software includes functions such as talk and listen, page, and manage intercoms and amplifiers from your Windows PC. Functions include:

  • Selective or master call to page all stations
  • Master control and auto-detection
  • Remote door release and GPIO control
  • Record, log, and archive audio sessions
  • Audio file playback (.WAV)
  • Remote and local digital volume control



For sophisticated users and applications, TalkMaster Enterprise Edition provides flexibility in addressing the special needs of complex, multi-station, multi-operator, and multi-site installations. The Talkmaster Focus suite of applications provides additional capability such as automation tools, vision, and VoIP connect.

Provides full intercom support: A powerful set of intercom call queue rules establishes site-specific call response hierarchies. You can communicate with intercoms from multiple sites and consoles, regardless of geography. TalkMaster-EE’s server-based topology can support 15,000 audio endpoints.

Support multiple Sites: This IP paging and Intercom system can be used in a single building, a campus, or multiple sites— locally or globally.

Records Transactions: Every substantial aspect of an intercom call transaction; among the information gathered and available on the Administration Console Screen are:

  • Console operator and administrator sign-in and sign-off,
  • Call start/stop including source,
  • Recording of both audio paths, and
  • Intercom call station status

Summary of TalkMaster Focus Suite Modules:

Enterprise Operator | Automation | Video | VoIP Connect | Bell Scheduler

Focus Enterprise Operator

License for additional operator consoles. This allows you to use more than one Windows computer to make pages.

Focus Automation Tools

This adds Alert Management and Events modules to the Focus Operator.

  • “If this…then that” capability
  • Trigger pre‐recorded audio files
  • Alerts for system interruption
  • Reads RSS/CAP: Atom Feeds
  • Scheduled Actions
  • Runs in the background

The Events Module adds the ability to monitor events from IP Endpoints and send audio or email messages in response to them.  For instance, you can connect a door switch to an IP Endpoint and play an automatic audio message when someone opens the door.

The Alert Manager module adds the ability to monitor RSS and CAP/Atom feeds and automatically convert the associated text messages to speech so they can be played on Digital Acoustics IP Endpoints.  For instance, this can be used to announce severe weather alerts from the National Oceanic and Atmospheric Administration. Or create your own RSS or CAP/Atom feed to create custom on-demand announcements.

Focus Video

This module allows operators to view live video from IP Cameras associated with IP audio endpoints.  Supports industry-standard RTSP based IP cameras.

By adding the Vision license to TalkMaster FOCUS, all Operator Consoles can see who they are talking to. Visually verifying a guest or intruder can be the difference between safety and danger.

Vision provides the ability to:

  • View an RTSP based IP Camera that has been associated with an IP Intercom
  • Continuously monitor up to four RTSP based IP Cameras

Focus VoIP Connect

FOCUS VoIP Connect is an optional component that provides SIP 2.0 integration with industry-standard SIP 2.0 VoIP Telephone systems.   TalkMaster FOCUS VoIP Connect adds the ability to assign an “extension number” to one or more IP Endpoints so they can communicate with phones on the SIP-based phone system.
