Atlas Sound AZMP4 Atmosphere™ 4-Zone Signal Processor with 600-Watt Amplifier

Product Overview

The AtlasIED Atmosphere AZMP4 is a 4-zone audio processor with a built-in 600-watt amplifier, designed as the central hub of an Atmosphere zoned audio control system for commercial spaces. It combines DSP processing, zone routing, paging, messaging, and amplification in a single rack unit, which reduces equipment count and simplifies commercial audio installation. System designers specify the AZMP4 for restaurants, offices, retail, education, and hospitality projects that need automated, multi-zone audio control without a separate amplifier rack. Configuration runs through an on-board web interface, so integrators can program zones from any browser.

Product Description

The AZMP4 pairs powerful DSP with practical automation features: a built-in message player, virtual wall controllers, learning ambient noise sensing, Tilter Filter, auto-gain, GPIO, a bell scheduler, and room combine. Its amplifier power sharing technology is the standout for system designers — the unit produces 600 watts total, and each output channel is software-assignable anywhere from 5 to 600 watts, so you size the system to real zone loads instead of overdesigning around fixed per-channel ratings. The processor supports all six Atmosphere wall plate accessories for zone control, remote audio input, and ambient noise sensing; up to 16 plug-and-play accessories connect across two accessory ports, each reliable up to 1,000 feet, and a zone paging station can be added for paging workflows. Programming uses a modern Progressive Web App interface that is device-agnostic and responsive, and built-in Wi-Fi lets tablets connect directly to the unit, either as an access point or joined to an existing network. For AV control system integration, AtlasIED publishes control modules for Crestron, Extron, AMX, and RTI, and a high-priority GPI input ties the audio system into fire alarm or life-safety muting. The platform also includes a full sound masking configuration suite, making the AZMP4 a strong fit for open-office speech privacy projects. Rear-view connections and zone outputs are shown below.

Pair the AZMP4 with 70V or 8-ohm loudspeakers from our AtlasIED collection to complete a multi-zone commercial audio system.

Key Features

Frequently Asked Questions

What is the difference between the AZMP4 and the AZM4?

The AZMP4 includes a built-in 600-watt power sharing amplifier, while the AZM4 is the processor-only version that requires external amplification. Choose the AZMP4 when you want zone processing and amplification in one rack unit.

Does the AZMP4 work with Crestron, Extron, or AMX control systems?

Yes. AtlasIED publishes control modules for Crestron, Extron, AMX, and RTI, and the unit supports third-party control over the network for integration into larger AV control systems.

How do end users adjust zone volume after installation?

Staff can use physical Atmosphere wall plate controllers or the app-less virtual wall controllers, accessed by scanning a QR code or opening a distributed URL on any phone or tablet.

Can the AZMP4 handle paging and scheduled announcements?

Yes. The built-in message player and bell scheduler handle automated announcements and bells, and a zone paging station accessory can be added for live paging.

Does it integrate with fire alarm systems?

Yes. A high-priority GPI input lets the audio system respond to alarm system triggers, such as muting program audio during an emergency event.

What speakers should I pair with the AZMP4?

The AZMP4 includes a large library of AtlasIED speaker presets and supports mono, stereo, and subwoofer configurations. Creation Networks can help you select compatible ceiling, surface-mount, or pendant loudspeakers for your zones.

What warranty applies to the AZMP4?

AtlasIED covers the AZMP4 with a 36-month warranty from the date of purchase.
