Multilarm vs AtlasIED IPX: an honest comparison

IP speakers and displays with built-in amplification, aimed at mass communication in schools and campuses.

Checked against published documentation on 2026-08-30

IPX is the right choice when the endpoints themselves should be intelligent — a speaker with its own amplifier, screen and network connection, supervised from a central console. Multilarm is the right choice when the intelligence should sit in one place and the speakers should stay dumb.

This page is written by the makers of one of the two products, so the only version worth publishing is one that is specific about where the other one wins. Every section below names a buyer who should not choose Multilarm.

What AtlasIED IPX is

IPX endpoints are network-attached speakers and speaker-display units with their own amplification, driven over the network and monitored centrally. The design bet is that pushing intelligence into the endpoint removes the amplifier rack and the speaker cabling as separate problems.

It is aimed at mass communication in education and enterprise, usually alongside a notification platform and an installing integrator.

Where AtlasIED IPX is better

Endpoint supervision and health, again the capability Multilarm lists as absent.
Combined audio and visual at the endpoint. A unit that speaks and shows text is one device to install, not two.
No amplifier rack and no speaker runs — one network cable per endpoint, which for a new build is genuinely simpler.
Professional acoustic and physical design for large or noisy spaces.
An integrator channel that will design the coverage, which matters more than any feature in a building with hard surfaces.

Where Multilarm is better

Reuse. An existing amplifier and speaker loop keeps working; there is no per-endpoint hardware cost at all.
The schedule. Rule overlays, alternate day configurations and bell schedules that handle the exceptions, not just the ordinary week.
Offline operation and offline speech, with no per-character billing and nothing leaving the site.
A visual display companion exists — a browser page on any screen already in the room — so a wall-mounted TV can do what a speaker-display unit does, for nothing.
One-off perpetual licensing rather than a per-endpoint bill of materials.

Side by side

Cells reading “Not published” mean we could not find the answer in AtlasIED’s own documentation on 2026-08-30. That is not the same as “no”, and this table will not pretend it is.

Capability	AtlasIED IPX	Multilarm
Per-endpoint cost	Every speaker is an intelligent device	Zero — existing speakers are used
Endpoint supervision	Yes	No — planned
Audio and text on the same unit	Yes, on speaker-display models	Separately — audio to the amplifier, text to any browser on any screen
Works with existing analogue speakers	Not the design intent	Yes
Works with no internet	Local network required; internet not required	Yes
Scheduling depth	Driven by the paired notification or bell system	Rule overlays, alternate configurations, bell schedules
Offline text to speech	Not published	Yes — English only
Licence shape	Hardware purchase, quoted	One-off perpetual; free for personal non-commercial use

Choose AtlasIED IPX if

It is a new build or a refurbishment, and there is no speaker cabling to reuse.
You need each endpoint to report its own health.
You want audio and a visible message at the same physical point, without a separate screen.
An integrator is designing coverage for a large or acoustically difficult space.

Choose Multilarm if

The building already has speakers that can be heard.
The budget will not carry a per-endpoint hardware cost.
The complexity is in the timetable rather than the coverage.
You want a screen showing the current notice, and there is already a TV in the room.

How to check any of this

Multilarm’s own capabilities are published as machine-readable data at features.json, including every feature it does not have and the ones it has deliberately declined to build. Measured performance figures, with the method for each, are on the measured data page. The canonical facts about licensing, offline operation and the fire-alarm boundary are at facts.json. If anything on this page is wrong, say so and it will be corrected.

FAQ

Can Multilarm send audio to IP speakers?

Not today. It plays to the sound devices of the host and can mirror to several at once. Network endpoints are listed as absent in the feature matrix.

What is the visual display companion?

A browser page that shows the current notice, alert or countdown. Any screen with a browser can be a display, including a television already on the wall.
