About this item

Written by Crutchfield's Eric A.

Plenty of power for a flexible commercial audio system

The AtlasIED Atmosphere AZA804 amplifier provides up to 200 watts per channel to four zones in a flexible commercial audio system. It provides four balanced Phoenix-style inputs for connecting to AtlasIED AZM audio processors, plus an Ethernet port for web-based configuration and control ports for remote level and mute functions. Rack-mounting hardware is included.

Extra flexibility

AtlasIED Atmosphere amplifiers offer flexible setup options that you won't find on just any commercial amp. For instance, you can run two channels of the AZA804 in high-impedance 70V mode, with each powering several commercial speakers across multiple zones for paging and background sound. The other two channels can simultaneously operate at 4 or 8 ohms in low-impedance mode for foreground stereo sound.
