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. If the design requires four channels of low impedance

amplification, the AZA amplifiers can be configured as four-channel models with either 4Ω or 8Ω load impedances. Many system designs require both

low and high impedance amplification. These AZA models can be configured to deliver 70V / 100V for a paging/background system on two (2) channels

plus two (2) additional 4Ω or 8Ω amplifier channels for foreground stereo application.

These AZA models come standard with four (4) balanced line inputs and an accessory slot for an optional four-channel Dante™ receiver card (model

DPA-DAC4), giving the AZA404 and AZA804 a total of up to eight (8) inputs. All inputs can be mixed and routed to any of the four amplifier channels.

All four (4) amplifier channels have an assortment of advanced DSP tools.

AZA Series amplifiers feature either network control. The AZA series amplifiers include a windows-based AZA Amplifier IP Discovery Tool that

automatically searches within a specific network for all available AZA amplifiers.

The AZA404 and AZA804 are ready to use, out of the box in four-channel, 70V mode, with no configuration or network connectivity required, making

them ideal for use with AtlasIED Atmosphere Zone Controllers.

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. The difference between models is the output power level.

Configuration #1 4 Channel 70V / 100V (Factory Default)

Owner’s Manual

1. Power Switch

This toggles the amplifier between Active Mode or Sleep Mode.

2. LED Power Indicator

The AZA amplifier has three states of idle power that are indicated as follows:

A. Active Mode - When the LED outer ring of the power switch illuminates a steady blue color, the amplifier is in Active Mode and is ready to

pass audio. This is AZA factory default shipping mode.

B. Sleep Mode - When the LED outer ring is Off, the unit is in Sleep Mode. In Sleep Mode, the Ethernet is active for access to the amplifiers on

board UI while the amplifier output stage and DSP are Off. Audio will not pass in Sleep Mode.

C. Standby APD Mode - When the amplifier Auto Power Down (APD) feature is enabled and the amplifier is in APD mode, the LED outer ring will

blink blue once every 5 seconds.

3. Operating Mode Indicators

Each AZA amplifier can be configured three ways. The LEDs in this area indicate the configuration of the amplifier. These indicators illuminate if

Channels 1 / 2 and 3 / 4 are operated separately in 4Ω / 8Ω mode or 70V / 100V mode. Amplifier operation mode setting is completed using the

internal DSP UI.

A. 4-Channel high impedance 70V / 100V mode

B. 4-Channel low impedance 4Ω or 8Ω mode

C. 2-Channel high impedance 70V / 100V mode & 2-Channel low impedance 4Ω / 8Ω mode

4. Channel 1, 2, 3, 4 Signal LED

The Signal LED will illuminate green if audio signal is present at that channel’s output.

5. Channel 1, 2, 3, 4 Limit/Protect/Mute LED

The Limit/ Protect LEDs will illuminate red if one of the following conditions occurs:

A. Any channel of the AZA amplifier reaches maximum output power. The AZA features an adjustable amplifier OUTPUT limiter which helps

prevent the amplifier from hard clipping. An occasional flash of the LED is OK but if the LED illuminates continuously reduce the amplifier’s

input level. If the Clip LED remains On after reducing the input level, recheck the load connected to the amplifier.

B. The OUTPUT has been muted in the UI.

C. A fault is detected within the amplifier. Once the fault is corrected, it may be required to reset the AC Mains power to reset the amplifier

protect mode.

6. Air Exhaust

Each model includes convection cooling with dynamic fan assist for extreme conditions. If the unit is not being used or is in Standby mode, the fan is

not needed for cooling and remains Off until the unit is in heavy use. As heat is generated in the amplifier during use, the fan activates at a low speed

and increases as needed to keep the amplifier at safe operating temperature. This cooling method eliminates the need for air filters that can become

clogged and require maintenance. The AZA amplifier’s air flow is from rear to front.
