This module is suitable for retrofitting audio equipment such as amplifiers, amplifier boards DY, amplifier preamps and so on.

Transform traditional wired transmission into wireless Bluetooth transmission, the module uses Qualcom 5.0 high-fidelity

The Bluetooth chip and Bluetooth 5.0 high version ensure high data transmission so that the audio data is transmitted losslessly to the analog power amplifier. To achieve wireless HF quality. The module supports 16bit / 48khz non-destructive reception, and the sound quality level reaches CD level. Is a truly lossless Bluetooth receiver module. This module receives Bluetooth, and the pcm5102a decoder core outputs standard single-ended analog audio signals. The audio signal can be directly added to the pre-stage or post-stage analog power amplifier without adding a DAC decoder. In order to facilitate the modification of DY friends, the module has a AUX input for external linear audio. The AUX and Bluetooth are switched by the original NEC high-precision relay. The AUX input is directly switched by the relay without any chip processing. Ensure the lossless output of AUX audio to the amplifier.

Specifications:

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

2. AUX audio interface, LINE_INR right channel input, GND common ground line LINE_INL left channel input

3. Audio output interface, ROUT right channel output, GND common ground line OUT left channel output

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

5. Bluetooth antenna buckle interface, used to install an external 2.4g antenna to enhance Bluetooth signal reception, open and unobstructed

6. Up to 20 meters or more, add an external antenna to support through-wall reception. If the module is installed in a metal chassis,

7. Install an external antenna (a 2.4G antenna like a router) to ensure complete signal reception. Outside plastic

8. No external antenna is needed on the side of the case or wooden case.

9. Bluetooth working indicator 1

10. Bluetooth working indicator

Tips:

If after the modification, the Bluetooth amplifier has a slight noise or interference noise when working, add a low-power power supply above 6-36V50MA and separate the Bluetooth module to solve the noise problem. Shared power with equipment is prone to common ground interference and noise floor

Package Included:

1 x  bluetooth 5.0 Receiving DAC Decoder
