Digital Media Player BrightSign AU335 Blue 100 Mbit/s Ethernet Dolby Atmos

The BrightSign AU335 Blue is an affordable, cloud-enabled digital media player designed for high-quality audio distribution. It supports multi-channel playback and advanced audio formats, including Dolby Atmos, and provides 100 Mbit/s Ethernet connectivity. The unit supports ARC/eARC for high-bandwidth audio output to compatible soundbars and AV receivers, and offers USB, GPIO and Ethernet-based interactive controls. With synchronization features for multiple BrightSign players and low typical power consumption, the AU335 is suitable for deployment where reliable, high-fidelity audio is required.

Advantages

The AU335 can play and mix up to three audio files simultaneously, enabling background music with voice overlays or layered soundtracks. ARC/eARC support allows distribution of 24-bit, high-bandwidth audio including Dolby Atmos to external devices. Interactive interfaces (USB, GPIO, Ethernet) and support for CEC commands let the player trigger and synchronize lighting or other peripherals. The device combines cloud management, straightforward deployment and BrightSign’s reliability in a compact, cost-effective form factor.

Suitable for

• Background music distribution across venues and multiple locations
