The AtlasIED AZMP4-D is a professional 4-zone audio processor and amplifier built for installed sound in commercial facilities including offices, hospitality, education, and retail environments. It combines a 600-watt amplifier with advanced digital signal processing, Dante networked audio, and a comprehensive feature set designed to reduce system complexity while maintaining flexibility across zones.

The AZMP4-D serves as the control hub for an Atmosphere audio system, managing multiple input sources, zone mixing, and independent amplifier power allocation across four zones. Its power-sharing amplifier technology assigns wattage dynamically between channels, eliminating the need for oversized amplifier configurations. Built-in capabilities include message playback, bell scheduling, room combining, auto-gain control, ambient noise compensation, and a Tilter Filter for frequency management. Dante connectivity enables seamless audio distribution to compatible devices across standard networked cabling up to 1000 feet, while dual accessory ports support up to 16 wall-plate controllers, sensors, and auxiliary audio inputs.

Programming is handled through a modern web interface optimized for common installed sound workflows, with on-board Wi-Fi and Ethernet connectivity. The unit supports control integration via RTI, Crestron, Extron, and AMX platforms, making it compatible with existing building automation and AV control systems. The AZMP4-D is the centerpiece for scalable, manageable commercial audio in spaces requiring multi-zone control without the overhead of traditional separate amplifiers and processors.
