The Atmosphere A-BT is a remote Bluetooth™ audio input (mono) to an Atmosphere AZM audio processor. This expansion allows the Bluetooth™ receiver to be optimally placed for wireless coverage. The AZM will automatically detect the A-BT and dynamically assign appropriate audio settings, such as makeup gain, EQ, and auto gain control, to that input. The stereo source audio is summed to a mono signal before being sent to the AZM.

Each Atmosphere accessory is a plug-and-play, intelligent device, specifically designed to be approachable and intuitive. The Atmosphere accessory bus allows for up to 8 devices to be connected to a single accessory port, reliably sending audio and data over 1000ft per port. Up to 1x audio input accessory can be added to each accessory port.
