Features: - Adapt to any audio device to Bluetooth transmission - Two boards can be connected to each other - Can receive any Bluetooth signal - It can transmit audio signal to any Bluetooth receiving device ?
Bluetooth Sending Mode: Bluetooth transmission - convert audio signal to Bluetooth signal, and provide it to devices that need to use Bluetooth to receive, such as: Bluetooth speaker, Bluetooth headset, Bluetooth card and other receiving terminals. Bluetooth transmission mode is defined as the main device, which needs to be paired and linked from devices such as Bluetooth speaker and Bluetooth headset. After it is defined as Bluetooth transmission mode, this device is the device that sends audio, so the output interface terminal has no output and can only input signals. Bluetooth transmission and reception mode has memory saving function. After selection, the power-off mode will not change next time. It is convenient to use pairing and automatic connection directly when receiving or sending
Bluetooth Receiving Mode: the Bluetooth audio signal received by Bluetooth can be paired and connected with the Bluetooth signal sent by mobile phones and other devices. The received Bluetooth signal can be decoded into stereo left and right channel signal, and the stereo signal can be output directly by optical fiber / coaxial. If you need to receive Bluetooth connection steps: 1: press the Bluetooth receive button, set it to Bluetooth receive mode, the blue light is not paired into the flash state, and the pairing succeeds. The Bluetooth name is audio-rx, please connect the Bluetooth name when pairing the mobile phone 2: select the required interface connection cable according to your own audio equipment such as power amplifier, headphone output, optical fiber output and coaxial output
Package Included: 1 x bluetooth 5.0 Audio DAC ADC 24 Bit Transmit Receive Converter
