AZA Series Owner’s Manual Introduction The AtlasIED Atmosphere AZA404 and AZA804 are four-channel amplifiers that are designed to interface with the Atmosphere family of products, such as the AZM series of processors. The AZA amplifiers can be configured in three different configurations to meet the design requirements of any installation. These AZA models are factory preconfigured in a four-channel, 70V mode.
AZA Series Owner’s Manual Applications AZA Series amplifiers integrate with Atmosphere signal processors which makes them ideal for use in restaurants, presentation rooms, classrooms, conference rooms, and retail background/foreground music applications. AZA Amplifier Configurations Note: For illustration purposes, model AZA404 is used for all examples. The AZA804 will be wired and configured identically to the AZA404. All AZA models have the same features and panel layout.

IEC AC Receptacle The AZA amplifier can operate between 110VAC - 120VAC (115V AC Mains Line Voltage Selection) or between 220VAC - 240VAC (230V AC Mains Line Voltage Selection). The included IEC cord is designed to work with 110VAC - 120VAC. A compatible IEC cord will need to be purchased for 220VAC - 240VAC operation. The IEC receptacle houses the AC mains fuse. Note: Changing the fuse must be completed by a qualified technician.
AZA Series Owner’s Manual Rear Panel 4. Speaker Connection A screw terminal block connector is supplied to connect speakers to the AZA amplifier. It is recommended to use Class 3 rated, 14-gauge wire or lower for speaker wiring. Amplifier output channel configurations are in the amplifier web UI. The AZA is shipped with two speaker output terminal covers. AtlasIED recommends placing the security covers on the amplifier after wiring and before turning the amplifier on for configuration.
AZA Series Owner’s Manual Finding an AZA Amplifier On a LAN AZA amplifiers include a unique set of features and configurations. All AZA amplifiers are configured from the factory out of the box to operate as traditional commercial power amplifiers. Ethernet connectivity is not required for operation. When used with Atmosphere signal processors only the Output Mode may need to be changed (default is 70V).
AZA Series Owner’s Manual Finding an AZA Amplifier On a LAN II. Web Browser via Network Router This method is very similar to the Direct Connection method covered in Section 1 but uses a web browser on the local network to discover the AZA amplifier. 1. Connect the AZA Amplifier using a standard Ethernet cable to a router. Make sure the router is in DHCP mode. 2. Connect a computer to the same router via an Ethernet cable or Wi-Fi. 3.
AZA Series Owner’s Manual Logging into The Amplifier The First Time Once you have entered in the web browser via one of the methods listed above, you will be prompted to enter the factory default Username (admin) and Password (admin). After entering the factory default Username and Password the AZA amplifier UI will open with a pop up window stating “Default Password detected. You must change the password!”. Select close and go to the User Settings section to change the password.
AZA Series Owner’s Manual AZA UI Overview When the AZA UI is accessed for the first time, the user will see the following settings in image below. These AZA settings are preset to mate with the Atmosphere Zone Master. Audio levels and EQ settings are handled in the Atmosphere Zone Master. 2 1 11 1.

When this box is checked the unit is in Auto Power Down (APD) mode.
AZA Series Owner’s Manual Firmware Revision It may be required to update the firmware on the amp to gain access to feature enhancements or bug fixes. The UI home page contains the firmware revision number installed in the amplifier. Visit https://www.atlasied.com/Atmosphere/AZA/, choose the AZA model being updated, and click the “Support Files” tab.

Apply AC power, wait 3 - 5 seconds, then press and hold the front power button for 5 seconds. The power LED will illuminate solid, then all of the front panel LEDs will start to blink rapidly. Release the power switch. You are able to log in once the LEDs stop blinking. 3. DHCP will be reset and both the username and password will be reset to “admin”.
AZA Series Owner’s Manual Installation and Considerations Cabling - These amplifiers can be used with either balanced or unbalanced sources, provided the proper cabling is used. A balanced line is defined as two-conductor shielded cable with the two center conductors carrying the same signal but of opposite polarity when referenced to ground. An unbalanced line is generally a single-conductor shielded cable with the center conductor carrying the signal and the shield at ground potential.
