A Robust Power Amplifier with Networking and DSP The AtlasIED Atmosphere AZA404 is a 400-watt, 4-channel power amplifier that boasts full compatibility with the company's other Atmosphere products, including AZM signal processors. The AZA404 can be configured in pairs to deliver up to 100 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 AZA404'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 AZA404 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
