Setting Up

Connecting to Your TV

The transmitter dock must be connected to a power source using the provided charger in order to function. Once the transmitter dock is connected to a power source, you can connect it to your TV. You can choose one of 3 different ways to do this:

OPTION 1: Optical port (recommended)

Plug the provided optical audio cable into the TV's optical OUT or "OPT OUT" port, then plug the other end into the transmitter's optical port in the "INPUT FROM TV" section.

NOTE: Most TVs support audio output through only one digital output port at a time, so if your TV's HDMI ARC port is in use, the optical port may be disabled. You can either disconnect the HDMI ARC device, or try connecting the transmitter via RCA / AUX.

OPTION 2: AUX 3.5mm port

Plug the provided AUX 3.5mm audio cable into the TV's AUX 3.5mm output port, then plug the other end into the transmitter's AUX 3.5mm port in the "INPUT FROM TV" section.

OPTION 3: RCA port

Attach the provided RCA adapter to the AUX 3.5mm audio cable. Plug the red & white RCA connectors into the TV's "AUDIO OUT" ports, then plug the other end into the transmitter's AUX 3.5mm port in the "INPUT FROM TV" section.

Connecting the Earbuds to the Transmitter

Setting Up Your TV (FOR OPTICAL CONNECTIONS ONLY)

Proceed to AUDIO OUTPUT and select "OPTICAL OUT / DIGITAL OUT". Many TVs will do this automatically; skip this step as needed.

STEP 3
Set the AUDIO OUTPUT format to "PCM / STEREO" ON or "DOLBY "OFF.

FAQ

Below are some of the most common questions people have during setup.

Can I have audio through my TV's speakers and wireless earbuds at the same time?
This completely depends on whether or not your TV supports the ability to output audio to 2 sources simultaneously. You can try a few different methods to test if your TV is capable of this or not - please refer to avantree.com/381/sound for more details.

My earbuds have no sound when connected to the transmitter – what do I do?
Check to ensure your earbuds are successfully connected to the Transmitter. Once connected, both the LED indicator on the earbuds and the LED indicator on the transmitter will turn solid green.
If you're still not receiving sound, check that the proper audio signal is being sent to the transmitter.
If using an RCA / AUX connection, set your TV's audio output settings to "Headphone" or "External Speakers." If using an OPT connection, turn "PCM / STEREO" ON or "DOLBY" OFF.
For RCA / AUX connections, you can also connect the TV's output port directly to a pair of headphones and test for audio. If there's no sound, then that probably means your TV's port is defective.
Please refer to avantree.com/381/no-sound for more details.
