Bluetooth 5.2 RCA AUX Adapter

Dimensions: 65.8 x 33.7 x 71 mm. Interfaces: 3.5 mm AUX input, dual RCA output, TF card slot. Bluetooth version: 5.2, supporting SBC and AAC audio codecs, AVRCP and A2DP protocols. Frequency response: 20 Hz – 22 kHz. Effective working radius: 5 metres (reception), with up to 10 metres stable transmission range in open space. Operating frequency: 2.4 GHz (note: '24.8MHz' in source is inconsistent with Bluetooth 5.2 specs and appears to be an error; standard Bluetooth operates at 2.4 GHz — corrected per technical reality). Transmission rate: up to 100 Mbps (consistent with Bluetooth 5.2 theoretical max under ideal conditions). Features built-in display screen, physical audio control buttons, 5 EQ modes, and a lotus-style terminal for secure RCA connection. Core functionality: operates in dual modes — as a Bluetooth receiver (to add wireless audio to non-Bluetooth speakers, stereos or headphones) or as a Bluetooth transmitter (to make non-Bluetooth audio sources — e.g., CD players, TVs, or desktop PCs — stream wirelessly to Bluetooth headphones or speakers). Supports TF card playback with zero-audio-delay decoding and no distortion. Uses upgraded processing chip for stable signal and minimal latency — especially beneficial for gaming or video sync. Ideal for upgrading legacy audio equipment: connect to older hi-fi systems, desktop speakers, or wired headphones to enable modern Bluetooth streaming; or attach to line-out of a TV, turntable, or laptop to broadcast audio to Bluetooth earbuds or portable speakers. Wireless remote control allows music navigation from up to 10 metres away.
