This module is suitable for modifying audio equipment such as power amplifier, power amplifier board DIY, power amplifier pre-effects and so on. The traditional wired transmission is converted into wireless Bluetooth transmission. The module uses Qualcomm 5.0 high-fidelity Bluetooth chip, and the Bluetooth 5.0 high version guarantees high-speed data transmission, so that the audio data is transmitted to the analog power amplifier without loss. To achieve wireless HIFI level sound quality. The module supports 16bit/48khz lossless reception and the sound quality reaches the CD level. It is a truly lossless Bluetooth receiver module. The module is Bluetooth-receiving and the pcm5102a decoder chip outputs a standard single-ended analog audio signal. Audio signals can be directly supplied to the preamp or post analog amplifier without the need for an additional DAC decoder. In order to facilitate the conversion of DIY friends, the module has been designed with a -AUX input for easy external wiring. The AUX high-precision relay is used between AUX and Bluetooth to switch AUX input without any chip processing, and the output is directly switched by the relay. Ensure lossless output of AUX audio to the amplifier.

①. DC power input interface. GND is the negative pole of the power supply, +12V is the positive pole of the power supply. Wide voltage: 6-36V

②. AUX audio interface, LINE_ JNR right channel input, GND common ground, LINE_ JNL left channel input

③. Audio output interface, R_OUT right channel output, GND common ground, L OUT left channel output

④. Audio switching relay, NEC imported, guarantees sound quality transmission and working life.

5. Bluetooth antenna buckle interface for external 2. 4g antenna, enhanced Bluetooth signal reception, open and unobstructed up to 20 meters or more, add external antenna to support through the wall, if the module is installed in the metal chassis An external antenna (2.4G antenna of the router) needs to be installed to ensure complete reception of the signal. No external antenna is required on the side of the plastic case or the wooden case.

⑥. Bluetooth work indicator 1

⑦. Bluetooth work indicator 2

Tips: If the Bluetooth is working, the amplifier has a slight noise or interference sound, and a small power supply of 6--36V 500MA or more is given to the Bluetooth module independently. The noise floor problem can be solved. Sharing power with the device is prone to co-interference noise floor noise

The JC-303 modules are all manufactured with new and original genuine components to ensure the performance and longevity of the modules. Environmentally friendly production process. The filter capacitor uses Nikon and Fujitsu solid-state high-capacity capacitors. The noise floor of the board is almost inaudible.
