The AX130 is an HDMI-ARC audio adapter that allows simultaneous audio output via Toslink, RCA, and 3.5mm jack, making it ideal for modern TVs without traditional audio outputs. It connects directly to the TV via HDMI-ARC or HDMI-eARC and flexibly routes the sound to soundbars, speakers, or headphones. For stereo signals, all three audio outputs can be used in parallel. The volume of the analog outputs can be conveniently controlled with the TV remote via HDMI-CEC. A switch on the device allows toggling between Stereo (2.0) and Dolby Digital (5.1), provided the TV supports it. The digital Toslink output supports PCM Stereo, Dolby Digital, and DTS, while the analog outputs provide stereo sound. Power is supplied via USB-C, ideally directly from the TV, allowing the AX130 to turn on and off automatically. With compact dimensions of 90 × 80 × 20 mm, the adapter can be placed discreetly.
