AX130 HDMI ARC Audio Adapter (OPT | Cinch | AUX)

AX130 HDMI ARC Audio TV Adapter for simultaneous audio output via Toslink, RCA and AUX

The smart bridge between your TV and your sound solution.

The AX130 is the ideal solution for conveniently routing your TV's audio to external audio devices – simply via your TV's HDMI-ARC or HDMI-eARC port. Whether it's a home theater system, headphones, or speakers – the AX130 ensures flexible sound enjoyment. The AX130 was developed with the latest generation of TVs in mind, which often lack traditional audio outputs and only offer HDMI-ARC or HDMI-eARC.

Versatile audio output

The AX130 offers three different audio output options:

• Digital (SPDIF Toslink in stereo, Dolby Digital or DTS)

• Analog RCA (stereo)

• Analog 3.5 mm jack (stereo)

With stereo, you can use all three outputs simultaneously. This means you can listen to the TV sound simultaneously through a soundbar with an optical cable and headphones. Thanks to HDMI-CEC, you can conveniently control the volume of the analog outputs with your existing TV remote control —no additional accessories required.

Sound format selection – 2.0 or 5.1

An innovative switch button on the device allows you to switch between stereo (2.0) and Dolby Digital (5.1) – provided your TV supports this feature. This switch is especially useful if you have multiple audio devices connected at the same time.

Note: This feature is new and not yet supported by all TV models. Alternatively, you can manually set the audio format to PCM or Dolby Digital in the TV menu.

Format compatibility

• Analog outputs (RCA & jack): Stereo playback only

• Digital output (Toslink): Stereo and Dolby Digital (5.1) possible
  When Dolby Digital is enabled, the analog outputs remain muted.

Easy to use

• Audio format switch button directly on the device

• Turn the Audio Extractor on/off by pressing and holding (5 seconds), if desired

Power supply

The AX130 is powered via a USB cable, directly from the TV. This means the AX130 automatically turns on and off along with the TV. Alternatively, you can use a USB port on another device or a USB power adapter (e.g., a phone charger). Any USB power source is suitable.

Important to know:

If the AX130 is recognized and activated by the TV, the internal TV speakers are usually automatically deactivated . Audio output is then exclusively via the connected AX130. Most TVs will then no longer display the volume visually as a numerical value, but instead display +/- as changes are made.
