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:
When working to integrate legacy paging amplifiers to an IP based systems. This is the go-to adapter for most set ups 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.

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 balance 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 Integrations
Below are details on how to connect an Algo paging adapter with various legacy amplifiers.
On the 8301 web interface, go to Basic Settings -> Features and set the Line Out Analog Output Level to 0dBm 600 ohm (0.775 Vrms)
Before connecting, power off PCM2000 system. Set the dip switch as demonstrated above (CC switch down and P/P switch middle).
The Bogen Amp Dedicated audio output available standard on most telephone systems
Can be connected directly to the input of most amplifiers
Traditionally, a 600-ohm dry audio signal and a normally
Control contacts, if available, activate during a page and typically control the muting of background music
The Algo 8301 Typical application: The Algo 8301 paging adapter and scheulder is used to connect and existing amplifier to UC environment as a SIP extension or a multicast endpoint.
Line output of the 8301 is connected directly to the dry audio input of the amplifier with input impedance between 600ohms and 10kOhms
For amplifiers connected directly to the dry page port of an existing telephone system, the 8301 will provide a very similar interface providing both dry page audio and dry contact closure to activate the amplifier (if required)
For amplifiers connect to an FXS or ATA through a “telephone answering device”, the 8301 will replace the answering device and eliminate the need for an FXS or ATA.
The 8373 is designed to provide a Line Out for audio to a traditional amplifier.
On the 8373 web interface, go to Basic Settings → Features and set the Line Out Analog Output Level to 0dBm 600 ohm (0.775 Vrms)
Loop the power of the amplifier into the 8373 to switch up to 500W (for 70V output) into 1-3 audio channels. At 25V the 8373 can switch up to 180W and 720W at 100V.
The speaker runs will be connected to the channel outputs on the 8373.
TOA Amp: The impedance is set from factory to 10 kΩ. To switch to 600 Ω, change the position of the unit's internal jumper switch JP204 as per diagram below.
On the 8301 web interface, go to Basic Settings → Features and set the Line Out Analog Output Level to 0dBm 600 ohm (0.775 Vrms)
On the 8301 web interface, go to Basic Settings → Features and set the Line Out Analog Output Level to -10dBm 600 ohm (0.245 Vrms)
The 8301 Line Out (terminal 3 and 4) connects to either the Tip and J3) using an RJ11 modular connector or the Page T and Page R inputs on the Valcom V-2001A via a 2-wire connection to the terminal strip.
On the 8301 web interface, go to Basic Settings → Features and set the Line Out Analog Output Level to 0dBm 600 ohm (0.775 Vrms)
If there are speakers connected to both channels, then an 8301 per channel will be required. One 8301 can be SIP registered and configured to Multicast to the second for zone paging including All Call.
