Use Audikast 4 / 4HA with a Soundbar

If you want to use your Audikast 4 / 4HA together with a soundbar and hearing aids or headphones, the setup depends on the type of connection your soundbar supports. This guide covers Optical and HDMI ARC connections.

Option 1: For Soundbar with Optical

If your soundbar uses an Optical connection, we recommend using an Optical Splitter.

Setup:

1. Connect the TV’s Optical Out to the Optical Splitter input.
2. Connect one splitter output to the Audikast 4 / 4HA transmitter.
3. Connect the other splitter output to the soundbar’s Optical input.

This allows both the soundbar and Audikast 4 / 4HA transmitter to receive TV audio simultaneously.

Option 2: For Soundbar with HDMI ARC

If your soundbar uses HDMI ARC, we recommend using the Avantree HAX06 HDMI ARC Audio Extractor.

Step-by-Step Setup:

1. Connect HAX06 to TV
   • Plug in the USB power cable (5V / 0.5–3A).
   • Connect the HAX06 HDMI ARC IN port to the TV’s HDMI ARC port.
2. Connect HAX06 to Soundbar
   • Connect HDMI ARC OUT from HAX06 to the soundbar’s HDMI ARC port.
3. Connect HAX06 to Audikast 4 / 4HA
   • Use OPT OUT on HAX06 to connect to the Audikast 4 / 4HA transmitter.
4. Set Bypass
   • Turn the Bypass switch on HAX06 to ON.
5. Turn Off TV eARC (if applicable)
   • If your TV supports eARC, ensure it is turned off to avoid signal conflicts.

Tip:

• If there is no sound through the Optical or RCA output, set the TV audio format to PCM.
• The Bypass LED on the HAX06 should display solid green when HDMI ARC is active.
