Features:
-Adapt to any audio device to Bluetooth transmission.
-Can realize the connection between two boards.
-Can receive any Bluetooth signal.
-Can transmit audio signals to any Bluetooth receiving device.
Bluetooth Sending Mode:
-Bluetooth transmission-convert audio signals into Bluetooth signals and provide them to devices that need to use Bluetooth receivers such as Bluetooth speakers, Bluetooth headsets, Bluetooth boards and other receiving terminals.
-The Bluetooth transmission mode is defined as the main device, which needs to be paired and linked from devices such as Bluetooth speakers and Bluetooth headsets. After being defined as the Bluetooth transmission mode, this device is a device that sends audio, so the output interface terminal has no output, only input signal.
-The Bluetooth transmission and reception mode has memory saving function. After selection, the power-off mode will not change the next time. It is convenient to use pairing and automatic connection directly when receiving or sending.
Bluetooth Receiving Mode:
-It can be paired and connected with the Bluetooth audio signal received by Bluetooth and the Bluetooth signal sent from the mobile phone and other devices, so that the received Bluetooth signal can be decoded into stereo left and right channel signals, and the fiber/coaxial output stereo signal can be directly output.
-To receive Bluetooth connection steps: 1: press the Bluetooth receiving button, set it to Bluetooth receiving mode. The blue light flashes fast when the pairing is not successful, but slowly flashes when pairing succeeds. The Bluetooth name is: Audio-RX, please connect Bluetooth name when pairing the mobile phone. 2: select the required interface connection cable, headphone output, optical fiber output, and coaxial output according to your own power amplifier and other audio equipment.
