Algo IP Paging Adapter Comparison: 8301 vs. 8305 vs. 8373
As organizations transition to VoIP systems, Algo’s 8301, 8305, and 8373 paging adapters are ideal solutions for bridging new IP systems to analog paging infrastructure and preserving traditional paging amplifiers and speakers.
The evolution of IP telephony has opened a world of efficiencies when it comes to communications. The ability to scale, keep costs consistent and predictable, and integrate with UCaaS platforms is music to the ears of many.
But, transitioning from analog to IP sustainably looks different for everyone. Unless you’re ready to invest, renovate, and re-train others all at once, it’s essential to consider how to ease into IP. One of the best ways to do this is with a paging adapter.
Algo IP Paging Adapters
Whether your focus is voice paging, alerting, or notifications, paging adapters can bridge VoIP systems and analog devices. 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.
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 IP Paging Adapter & Scheduler
- 8305 Multi-Interface IP Paging Adapter
- 8373 IP Zone Paging Adapter
While they all share a similar foundation, they were each designed with different use cases and environments in mind.
Key Differences of the 8301 vs 8305 vs 8373
| 8301 | 8305 | 8373 | |
|---|---|---|---|
| When to Choose | 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/FXO port) 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. |

In most applications where the legacy amplifier does not have dedicated speaker zones behind the amplifier, the 8301 is the ideal choice. However, where organizations utilized zoned paging amplifiers, the 8373 is required to retain legacy speaker zones behind the amplifier.
8301 IP Paging Adapter
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.
If you have multiple amplifiers in a facility, they would all require an 8301. After you SIP register this device and connect it to your legacy system via the balance line input, you can call the device to drive your speakers. You can configure the device via a web interface for your paging and multicast needs.
8305 Multi-Interface IP Paging Adapter
The 8305 is the ideal paging adapter for integrating legacy communication systems that contain an FXS port. It is very similar to the 8301, however, it was explicitly designed to create a hybrid VoIP environment by emulating an analog telephone.
The 8305 has a telephone port that connects to legacy communications with an FXS port. There is also an 8 W Output terminal block to connect one or many external self-amplified speakers connected in parallel with a total minimum resistance of 8 W.
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.
Analog speakers must be appropriately wired to the 8373 internal relays, which can switch up to 280 W using a 70 V amplifier or 400 W using a 100 V amplifier.
