    The AtlasIED Atmosphere AZA404 four-channel amplifier is designed to interface with the Atmosphere family of products, such as the AZM series of processors. The AZA amplifiers can be configured in pairs to deliver up to 100W per channel into both low and high impedance speaker loads (4Ω/8Ω/70V/100V).

    The AZA404 is ready to use out of the box in four-channel, 70V mode, with no additional configuration or network connectivity required, making them easily paired for use with AtlasIED Atmosphere signal processors.

    • 70V, 100V, 8Ω, or 4Ω functionality, configurable in channel pairs
    • Up to 100W per channel (4 x 100W)
    • Four (4) balanced inputs
    • Web interface to change output modes and additional monitoring/processing
    • Optional Accessory Card Slot for a Four-Channel Dante™ Receiver (DPA-DAC4)
