The Atmosphere A-RCA is a remote RCA/3.5mm audio input to an Atmosphere AZM audio processor. This expansion acts identically to the on-board RCA inputs. The AZM will automatically detect the A-RCA and dynamically assign appropriate audio settings, such as makeup gain, EQ, and auto gain control, to that input. The stereo inputs are 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 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.
