Bluetooth 5.0 Decoder Board DAC With Antenna Bluetooth Audio Receiver PCM5102A Decoding AUX 16bit 48KHZ For Amplifiers JC-305 uses Qualcomm QCC3005 Bluetooth solution, supports: AAC/SBC/A2DP/APTX/APTX-LL protocol JC-334 uses Qualcomm QCC3034 Bluetooth solution, supports: AAC/SBC/A2DP/APTX/APTX-LL/APTXHD protocol 1. This module is suitable for modifying the power amplifier, power amplifier board DIY. Amplifier pre-effects and other audio equment. The traditional wired transmiion is converted into wirele Bluetooth transmiion. 2. The module uses Qualcomm 5.0 high-fidelity Bluetooth ch. 3. The high version of Bluetooth 5.0 guarantees the high-speed transmiion of data, so that the audio data is transmitted to the og amplifier without lo. To achieve the wirele HIFI level sound quality. 4. The module supports 16bit/48 khz lole reception, and the sound quality level reaches the CD level. It is a truly lole Bluetooth receiver module. 5. The module is for Bluetooth reception, and the PCM5102A decoder ch outputs a standard single-ended og audio signal. It can directly provide audio signals to the preamp or post og amplifier. No additional DAC decoder is required. 6. To facilitate DIY, the module is designed with an AUX input for easy external wiring. The NEC high-precision relay is used for switching between AUX and Bluetooth. The AUX input is not proceed by any ch. The output is switched directly by the relay. Ensure lole output of AUX audio to the amplifier. Interface Descrtion: 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: DC6-36V 2 AUX audio interface, LINE_INR right channel input. GND common ground. LINE_INL 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 . Guaranteed sound quality transmiion and working life. 5 Bluetooth antenna bule interface for external 2.4g antenna. Enhanced Bluetooth signal reception. Open and unobstructed up to 20 meters or more. Install external antenna to support through the wall. If the module is installed in a metal chais. Install an external antenna (the 2.4G antenna of the router) to ensure complete reception of the signal. For example, plastic external charging or wooden housing side does not require an external antenna. 6 Bluetooth work indicator 1 7 Bluetooth work indicator 2 Note: If the Bluetooth is working, the amplifier has a slight noise or interference sound. Add a small power supply 6-36V 500MA or more. If the Bluetooth module is independent, the noise floor problem can be soed. Sharing power with the device is prone to common ground interference.
