Product Overview
The AZA804 4-channel 800-watt networkable amplifier is engineered to provide power to the Atlas Atmosphere family of products. Configurable in channel pairs, the AZA804 can deliver up to 100W per channel into 70/100V lines or 4/8 ohm loads providing options for installers.
Out of the box the AZA804 is set to 4-channel, 70V mode for easy pairing with AtlasIED Atmosphere signal processors and there's no additional programming or network connectivity needed. Plus, a web interface provides additional monitoring, processing, and the ability to change output modes.
