What Are Bluetooth Transmitters Used For?
Bluetooth transmitters are devices that convert wired audio signals into wireless Bluetooth streams, enabling non-Bluetooth TVs, gaming consoles, or stereos to connect with wireless headphones/speakers. Avantree’s transmitters specialize in low-latency transmission (≤40ms) for synchronized audio-video playback, supporting advanced codecs like aptX LL. They’re ideal for home theaters, gym equipment, and legacy car audio systems, often featuring dual pairing for shared listening.

Bluetooth transmitters bridge legacy audio systems to modern wireless gear via 3.5mm/RCA inputs. Avantree’s units like the DG60P convert analog signals to digital with 24-bit/48kHz sampling, reducing audio lag to 30ms. Pro Tip: For TVs, use transmitters with optical input (e.g., Avantree HT5000) to bypass low-quality DACs in older TV models. Imagine converting a 2005 stereo into a Spotify-ready system—transmitters act as universal adapters.
What compatibility factors matter most?
Key considerations include codec support (aptX HD vs. SBC) and transmission range. While most transmitters cover 10m, Avantree’s DG80 uses Class 1 Bluetooth for 30m+ range. Avoid models without NFC pairing if using multiple devices daily. A gamer using AirPods with an Xbox would need a transmitter supporting AAC codecs and USB-C power—mismatched codecs cause audible lip-sync errors.
| Transmitter Type | Best For | Limitations |
|---|---|---|
| USB-only (Plug-and-play) | Laptops/PCs | No RCA/optical inputs |
| Dual-Mode (Tx/Rx) | Car stereos | Higher power draw |
Can one transmitter connect to multiple devices?
High-end models support dual pairing, streaming to two headphones simultaneously. Avantree’s Ensemble pairs with 8 devices but only transmits to 2. Note: Sharing audio between Apple and Android devices often requires resetting the transmitter. Pro Tip: Use transmitters with “priority reconnection” to auto-link frequently used headphones—perfect for busy households.
How critical is latency for video/gaming?
Latency below 60ms is essential for gaming/TV. Standard SBC codecs have 150-300ms delays, while Avantree’s aptX LL transmitters achieve ≤40ms—inaudible sync gaps. For example, a 200ms delay makes dialogue feel dubbed. Most Nintendo Switch games require sub-70ms transmitters; otherwise, button presses and sound effects misalign.
| Use Case | Max Tolerable Latency | Recommended Codec |
|---|---|---|
| Movie Streaming | ≤80ms | aptX HD |
| Competitive Gaming | ≤40ms | aptX LL |
Do transmitters degrade audio quality?
They can if using lossy compression or low-bitrate codecs. Transmitters with LDAC or aptX HD (e.g., Avantree Orbit) preserve 24-bit/48kHz quality, while SBC transmitters compress audio to 328kbps. However, interference from 2.4GHz Wi-Fi can introduce artifacts. It’s like photocopying a photo—high-quality scanners (codecs) retain details; cheap ones blur them.

FAQs
Yes, but choose transmitters with ASHA protocol support (e.g., Avantree Relay) for direct streaming to hearing aids via iPhone, avoiding intermediary devices.
Why does my transmitter disconnect near the kitchen?Microwave ovens emit 2.4GHz interference—relocate the transmitter or use 5.8GHz alternatives like KleerNet, available in Avantree’s DG80 Pro model.
Do transmitters work with wireless earbuds?Absolutely. Pair them like any headphones—though multipoint models (e.g., Avantree Auditor) manage connections better when switching between phone calls and TV audio.
