Setup Your Audikast Transmitter

Plug In

- Connect to TV's audio output with Optical, AUX, or AUX to RCA cable.

- Subsequent: Press and hold the headphone icon until LED flashes red&blue.
Put headphone in pairing mode.

TV Setup
For Optical connection only: Change TV audio settings to “PCM / Stereo” to ensure sound output.

Play
Sit back, relax, and enjoy!
What range can I expect?
Audikast reaches up to 100ft / 30m in open space, but the range may vary due to obstacles, interference, headphone reception, and the number of devices connected to the transmitter.
Can I have audio through my TV’s speakers and wireless headphones at the same time?
It depends on whether your TV can output audio to two devices simultaneously. If not, we offer products for simultaneous TV audio on an external speaker and Bluetooth headphones.
I have a wall-mounted TV and cannot reach the audio-out ports in the back. Will this work with an HDMI-connected TV box?
This transmitter doesn’t have an HDMI port. However, by using the Audikast with our Avantree Hax05, an HDMI audio extractor, you can easily resolve this issue.
What devices are compatible with the Avantree Audikast Plus Bluetooth 5.3 Audio Transmitter?
The Avantree Audikast Plus is compatible with most Bluetooth headphones, speakers, and soundbars supporting aptX, aptX Low Latency, aptX-Adaptive, or SBC codecs. It can connect to two devices, but performance may vary by brand.
