Setup Steps

  1. Connect the TV's HDMI ARC / eARC port to HDMI ARC IN on the HAX06.
  2. Connect HDMI ARC OUT on the HAX06 to the soundbar's HDMI ARC input.
  3. Connect OPT OUT on the HAX06 to OPTICAL IN on Audikast 4 / 4HA.
  4. Turn on the TV, soundbar, HAX06, and Audikast 4 / 4HA.
HAX06 Setting: Set BYPASS → ON.
If There Is No Sound: If eARC is enabled on your TV, try switching to standard ARC mode by setting eARC → OFF. Also check that the correct TV audio output is selected.
Expected Result: Your soundbar receives TV audio through HDMI ARC, while Audikast 4 / 4HA receives audio through Optical.

No Sound from Audikast 4 / 4HA?

If the soundbar works but your headphones or hearing aids have no sound, check your TV's Digital Audio Output setting and try PCM.
