The AtlasIED AZA804 is a 1U, four-channel power amplifier engineered for installed commercial audio systems built around the AtlasIED Atmosphere ecosystem. AV integrators deploying distributed audio in corporate, hospitality, education, or house-of-worship environments gain a flexible amplification platform that pairs directly with AZM series processors without requiring additional configuration or network setup to begin operating in four-channel 70V mode.
Output flexibility is a core strength of the AZA804. Channel pairs can be independently configured for 70V, 100V, 8Ω, or 4Ω loads, allowing a single rack unit to address mixed speaker arrays within the same installation. Paired AZA804 units can be bridged to deliver maximum power allocation, scaling output to match demanding zone requirements. The Class AB switching hybrid BASH topology maintains efficiency without sacrificing audio fidelity across the full 20Hz–20kHz bandwidth.
For integrators requiring networked audio transport, an optional accessory card slot accepts the DPA-DAC4 four-channel Dante receiver, adding AoIP capability without external conversion hardware. The onboard web interface provides remote output mode switching and system monitoring, reducing the need for on-site adjustments post-installation. A 36-month warranty and auto-switching universal power supply round out a specification set built for professional install confidence.
