Descriptions:
1.Welcome to use this self-made Bluetooth Audio Receiver Starter Ver4.0. This receiver could work well together with Bluetooth adapter in your Laptop or Desktop computer, or mobile phones with Bluetooth audio stream output support.
2.It supports Bluetooth V4.0+EDR, and support A2DP protocol, it has a built in 3.5mm audio jack for audio output. You may also use the back panel 4pin connector to get another audio output channel. The distance from this unit and the Bluetooth transmitter could be up to 10meters but please notice that it may vary much based on the environment.
3.It can be connected with a Bluetooth adapter or a mobile phone with Bluetooth. The output terminal can be connected with a headphone or a power amplifier to transmit wirelessly. The maximum transmission distance is 10m.
4.Resistance and capacity components of high quality, including X7R ceramic capacitors and lower ESR electrolytic capacitors, are used to gain the perfect timber, finally realize high S/N ratio, low THD+N, wide frequency response range etc.
5.The Bluetooth audio receiver board contains anti-reverse function. The parts of analog and digital audio are powered by 2 independent chips, which mostly eradicate the RF and digital signal interference with the audio.
