Atlas Sound A-RCA-US-B – Atmosphere RCA/3.5mm Audio Input (Black)

Product Overview

The Atlas Sound A-RCA-US-B is a black Atmosphere accessory providing a remote RCA and 3.5mm audio input for the AtlasIED Atmosphere AZM audio processor. Designed for distributed background music and commercial paging systems, it extends the AZM's onboard audio input capability to any location on the accessory bus. The A-RCA-US-B is a plug-and-play Atmosphere wall plate accessory that simplifies audio source integration in hospitality, retail, corporate, and house-of-worship AV installations.

Product Description

The A-RCA-US-B functions as a remote extension of the Atmosphere AZM processor's onboard RCA inputs. Once connected to the accessory bus, the AZM automatically detects the A-RCA-US-B and assigns audio processing settings — including makeup gain, EQ, and auto gain control — without manual configuration. Both RCA and 3.5mm inputs are summed to mono before being sent to the AZM, ensuring compatibility with stereo consumer sources. The accessory bus supports up to 8 devices per port and can reliably transmit audio and data over distances exceeding 1,000 feet per port, making it suitable for large-venue or multi-room distributed audio deployments. The unit includes a screwless Decora wall plate for a finished installation appearance. Features include a signal presence indicator, digital audio return to the host processor, daisy-chain capability, and a high-priority notification function. The black finish (US model) matches standard commercial wall plate aesthetics. A 36-month warranty is included.
