Algo IP Paging Adapters provide balanced line outputs and connect directly with legacy amplifiers. Acting as a bridge between the VoIP system and legacy PA infrastructure, paging adapters enable organizations to broadcast voice paging across establishments of any size.

Algo IP paging adapters are designed to drive a traditional amplifier and maintain the integrity of the zoning used with your legacy infrastructure while replacing your legacy zone controller and other equipment to simplify your overall deployment.
This guide outlines how to connect Algo paging adapters to various legacy amplifiers and communication systems. Please note that models not explicitly mentioned in this guide are not necessarily incompatible with Algo paging adapters. If the model you are working with is not documented here, please contact support@algosolutions.com.
Algo Paging Adapters
All Algo IP Paging adapters have an audio output designed to emulate a page port on a legacy PBX. They also isolate and balance audio output and prevent additional humming or noise. There are currently three Algo IP paging adapters available:
8301 | 8305 | 8373 | |
|---|---|---|---|
When to Choose | When working to integrate legacy paging amplifiers into an IP-based system. This is the go-to adapter for most setups and needs. | When working to integrate legacy communication systems (specifically ones that have FXS and need to connect to a telephone) to an IP-based system. | When working to integrate a legacy zoned paging amplifier (up to three groups of analog speakers to retain zoning infrastructure) to an IP-based system. |
Multicast | Yes | Yes | Yes |
PoE | Yes | Yes | Yes |

Scheduler | Yes | Yes | No |

8301 IP Paging Adapter & Scheduler
The 8301 is the ideal paging adapter for most applications. The 8301 is the most direct paging gateway to bridge VoIP to analog systems. It’s designed to be a balanced line output to a single amplifier.

8305 Multi-Interface IP Paging Adapter
The 8305 is the ideal paging adapter for integrating legacy paging systems that provide a "talk battery pair". It is very similar to the 8301; however, it was explicitly designed to create a hybrid VoIP environment by emulating an analog telephone.

8373 IP Zone Paging Adapter
The 8373 IP Zone Paging Adapter is the ideal paging adapter to replace a legacy zone controller for up to three groups of analog speakers. This IP paging adapter is best if you want to retain zoning speakers as-is. The 8373 contains three high-powered relays that can be used to switch a single amplifier’s output signal.

Algo Paging Adapter Compatibility with Third-Party Amplifiers
Algo Paging Adapters can integrate with various legacy amplifiers. See the following table for an overview of compatibility.
Legend:
✓: Compatible.
✓✓: Recommended
*: Compatible. However, it is only recommended if the analog speaker requires zoning and the amplifier is incapable of doing so.
X: Not compatible
