What this adapter does

The AUTYUE A03#Q2061_B is a Bluetooth 5.1 transmitter and receiver in one unit. It adds wireless audio to TVs, home stereos or car systems and also works as a Bluetooth receiver for wired speakers. A built-in 1200mAh battery gives up to 8 hours of playback and 300 hours on standby.

Installation and common issues

Charge the unit for 1.5 hours via USB before first use. Switch between TX and RX modes with the slide switch, then pair by holding the multifunction button. The 3.5 mm AUX and RCA ports cover most TVs and amplifiers; the 6.5 mm jack accepts a microphone for KTV use. NFC tap-to-pair works only with compatible phones.

The spec that decides fit

Bluetooth 5.1 with DSP low-latency codec cuts delay from 220 ms to under 40 ms. If your headphones or speaker support the same codec you will get lip-sync-free audio; otherwise the link falls back to standard latency. The adapter also plays files from USB or TF cards in formats including MP3, WAV, FLAC and APE.
