A Robust Power Amplifier with Networking and DSP The AtlasIED Atmosphere AZA804 is an 800-watt, 4-channel power amplifier that boasts full compatibility with the company's other Atmosphere products, including AZM signal processors. The AZA804 can be configured in pairs to deliver up to 200 watts per channel into either low- or high-impedance speaker loads (4Ω/8Ω/70V/100V). It includes four balanced line inputs, plus an accessory slot for an optional 4-channel Dante receiver card (sold separately). All of the AZA804's inputs can be mixed and routed to any of its four channels, and all four channels include an array of advanced DSP tools. Here at Sweetwater, we've found that the AZA804 is ready to use out of the box, in 4-channel, 70V mode, with zero additional configuration or network connectivity required. What's more, its easy-to-use web interface makes changing output modes or accessing monitoring or processing parameters a piece of cake. The
