It can transmit audio signal to any Bluetooth receiving device

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 inter terminal has no output and can only input signals.

Bluetooth transmission and reception mode has memory saving ftion. 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

Pairing connection between Bluetooth and various devices:


After the Bluetooth device is set to send, the receiving device is adjusted to the pairing state and placed at the nearest distance for automatic pairing. For pairing, the following items need to be done:

1: Turn off the Bluetooth ftion of the mobile phone around you, and turn off other relevant Bluetooth devices that do not need to be paired (because the product is a device that actively looks for and tries to connect)

2: Place two paired devices as close as possible to each other

3: Wait for a while, and the product will actively find the device and try to connect (remember to turn off other unrelated devices)

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.


To receive a Bluetooth connection:

1: Press the Bluetooth receive button and set it as the Bluetooth receive mode. The blue light is not paired to the flash state. The pairing succeeds and the flash is slow. The Bluetooth name is audio-rx. Please connect the Bluetooth name when pairing the mobile phone

2: According to their own power amplifier and other audio equipment, choose the required inter cable, headphone output, optical output, coaxial output.
