Overview
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
What does the AUX input with relay do
Answer:This is to help solve the problem of adding a Bluetooth receiver board to an amplifier or active speaker with only one audio input.
For example, a computer active speaker has only one input function, and you cannot plug in an external sound source such as a computer sound card or a CD player when connected to a Bluetooth receiver board. The audio input needs to be unplugged, which is very inconvenient to use. If you have an AUX input, you can use the Bluetooth AUX interface to connect computer sound cards or CD players and other external sound sources. The Bluetooth receiver board output interface is connected to the active speaker input terminal, so you do n’t need to unplug the cable. AUX mode. After the Bluetooth connection, it will automatically switch the Bluetooth output, disconnecting the Bluetooth automatically switches to the AUX interface, and the power is also the AUX direct connection function.
