How To Use A Bluetooth Adaptor For Your TV?
To use a Bluetooth adaptor for your TV, connect the transmitter to your TV’s audio output (HDMI-ARC, optical, or RCA), power it via USB, then pair it with Bluetooth headphones or speakers. Avantree’s adaptors auto-sync with devices, supporting dual-streaming for two headphones. Ensure audio format compatibility (e.g., PCM for non-latency models) and adjust TV settings to prioritize external audio output.

What is a Bluetooth TV adaptor?
A Bluetooth TV adaptor transmits audio from non-Bluetooth TVs to wireless headphones/speakers via low-latency codecs like aptX LL. Avantree models feature dual pairing, 30m range, and automatic reconnection. Critical specs include input ports (TOSLINK, RCA), battery life (if portable), and codec support for lip-sync accuracy.
Bluetooth TV adaptors bridge analog/digital audio outputs to wireless devices. For instance, Avantree’s Audikast Plus connects via HDMI-ARC, decoding Dolby Digital for 5.1 surround sound. Pro Tip: If using optical audio, disable your TV’s internal speakers via settings to force signal routing. Ever wondered why some adaptors need a USB-C port? It’s for firmware updates—essential for maintaining compatibility with new TV models.
How to install a Bluetooth adaptor?
Installation steps: 1) Identify your TV’s audio output. 2) Connect the adaptor (HDMI-ARC > optical > RCA). 3) Power via USB. 4) Activate pairing mode. Avantree transmitters like the DG60P automatically detect active ports, while cheaper models require manual input switching. Check for Dolby/DTS conflicts if using HDMI.
First, confirm your TV supports audio passthrough—some budget TVs only output stereo via RCA. For HDMI-ARC, enable CEC controls so volume adjusts via your remote. Practically speaking, optical connections offer better fidelity but may require enabling PCM in TV sound settings. Pro Tip: Label cables if switching between multiple devices. Did you know Avantree’s adaptors include rubberized feet? They prevent slippage behind wall-mounted TVs where airflow is restricted.
| Connection Type | Pros | Cons |
|---|---|---|
| HDMI-ARC | Supports surround sound | Requires CEC activation |
| Optical | High-fidelity audio | No volume control |
| RCA | Universal compatibility | Stereo only |
How to pair headphones?
Pairing process: Enable pairing mode on the adaptor (LED blinks), then activate discovery on headphones. Avantree devices store up to 8 paired devices and prioritize the last connected. For aptX LL headphones, maintain line-of-sight within 10m to minimize lag.
Hold the adaptor’s pairing button until LEDs flash blue/red. Then, initiate pairing on headphones (consult manuals for specific steps). Why does audio sometimes stutter? Interference from Wi-Fi routers or microwaves—relocate the adaptor or switch to 5GHz networks. For multi-user setups, Avantree’s DG80S supports two headphones simultaneously, ideal for shared viewing without lag discrepancies.
Do Bluetooth adaptors cause audio delay?
Latency varies from 32ms (aptX LL) to 300ms (SBC). Avantree’s aptX-encoded transmitters minimize delay to 40ms, aligning audio with on-screen action. Check codec compatibility between adaptor and headphones—mismatches default to high-latency SBC.
Lip-sync issues arise when TVs process audio slower than video. To fix this, some adaptors include latency adjustment (e.g., +200ms delay to match video). Pro Tip: If your TV has a Game Mode, enable it—it bypasses processing lag. Real-world example: A Samsung QLED TV with default settings adds 120ms delay, but pairing with Avantree’s FastStream adaptors keeps total latency under 150ms, imperceptible to most users.

FAQs
Yes, if your TV has RCA, optical, or HDMI-ARC outputs. Older CRT TVs require RCA-to-3.5mm converters, but Avantree’s adaptors include these cables.
Can I connect multiple headphones?Only with dual-streaming adaptors like Avantree DG80S. Standard models connect to one device at a time—check product specs for multi-pairing support.
Do all adaptors support mic input?No—most TV transmitters are receive-only. For voice calls, use adaptors with dedicated mic ports like Avantree’s Pro.
