Description

Bluetooth Decoder Board 5.0 Audio Receiver Decoding AUX Supported For Amplifiers
Features:
1. This module is suitable for modifying the power amplifier, power amplifier board DIY. Amplifier pre-effects and other audio equipment. The traditional wired transmission is converted into wireless Bluetooth transmission.
2. The module uses Qualcomm 5.0 high-fidelity Bluetooth chip.
3. The high version of Bluetooth 5.0 guarantees the high-speed transmission of data, so that the audio data is transmitted to the analog amplifier without loss. To achieve the wireless HIFI level sound quality.
4. The module supports 16bit/48 khz lossless reception, and the sound quality level reaches the CD level. It is a truly lossless Bluetooth receiver module.
5. The module is for Bluetooth reception, and the PCM5102A decoder chip outputs a standard single-ended analog audio signal. It can directly provide audio signals to the preamp or post analog amplifier. No additional DAC decoder is required.
6. To facilitate DIY, the module is designed with an AUX input for easy external wiring. The original imported NEC high-precision relay is used for switching between AUX and Bluetooth. The AUX input is not processed by any chip. The output is switched directly by the relay. Ensure lossless output of AUX audio to the amplifier.
Interface Description：
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 original imported. Guaranteed 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. Install external antenna to support through the wall. If the module is installed in a metal chassis. 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.

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 solved.
Sharing power with the device is prone to common ground interference.
Package Includes:
