Follow each step in order. We show what to do, what to look for, and how to fix it.
Step 1
Power the transmitter.
Place it near the TV. Keep the audio cable loose, not stretched.
Connect power
Use the included USB-C power cable.
Connect USB-C to the transmitter.
Connect USB-A to a 5 V, 500 mA–2 A power source.
Slide Volume Boost / OFF / ON to ON.
✓
Expected: the transmitter turns on. The audio-signal light may blink until the TV sends sound.
No light? Reconnect both cable ends. Then try another USB power source.
Step 2
Choose one TV audio output.
Look at the labels on the back or side of the TV, then choose the matching path.
Using a soundbar? Complete headphone setup first. Optical and AUX pass-through are covered later; HDMI ARC soundbars cannot share the ARC port directly.
Which TV output do you have?
Tap the socket label you see. Only HDMI ARC? Choose HAX06.
Connect with Optical
Remove the protective caps from both cable ends.
Connect TV OPTICAL / DIGITAL AUDIO OUT to transmitter OPT IN.
Set the transmitter Input Selector to OPT.
Next: set the TV sound output to Optical/External Speaker and Digital Audio Format to PCM.
Connect an HDMI-only TV with HAX06
Connect the TV port labeled HDMI ARC or eARC to the HAX06 adapter.
Connect HAX06 OPTICAL OUT to Medley Pebble 2 OPT IN.
Set the transmitter input to OPT.
Important: Medley Pebble 2 does not support HDMI ARC directly. On the TV select HDMI ARC/Receiver, turn eARC off if required, and choose PCM/Stereo.
Connect with AUX / 3.5 mm
Connect TV HEADPHONES / AUDIO OUT to transmitter AUX IN.
Set the transmitter Input Selector to AUX.
Set TV sound output to Earphones and raise TV volume to a normal level.
Next: play a program with speech; PCM is normally not required for analog AUX.
Step 3
