The Atmosphere A-BT is a remote Bluetooth audio input (stereo or 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 1000' per port. Up to 1x audio input accessory can be added to each accessory port.
