TDA7498 Bluetooth5.0 Digital Amplifiers Board 2 Channel Audio module 2*100W AUX

Description

Description:
XH-A105 Bluetooth power amplifier board, using imported power amplifier chip, has high-fidelity stereo sound quality. Support Bluetooth, TF card, AUX audio input. The amplifier is equipped with Bluetooth 5.0 high-speed transmission, and the Bluetooth effective transmission distance is 20 meters without barriers. Depending on the Bluetooth configuration of the individual mobile phone, the signal strength will vary, and the transmission distance will vary. The input power of the power amplifier is DC12-30V, with dual-channel output, the output impedance is 4-8Ω, the maximum power is 100W * 2. The on-board volume adjustment potentiometer can freely adjust the volume.
Advantages of Bluetooth 5.0:
1. Compared with Bluetooth 4.0 / 4.2, the transmission efficiency is improved by 2 times.
2. The transmission distance is increased by 4 times.
3. Broadcast mode information capacity has been increased by 8 times.
The broadcast communication capacity is upgraded from 31Byte of Bluetooth 4.2 to 255Byte, and the enhanced broadcast capability will bring better beacons. In order to create more location-based indoor positioning services and navigation services, data can be transmitted without pairing and connection. The accuracy of indoor positioning is less than 1 meter, which improves the accuracy of indoor positioning.
4. Lower power consumption and compatible with older Bluetooth versions.
To meet the needs of the mobile Internet, its power consumption is lower and it is compatible with older Bluetooth versions. The Bluetooth 5.0 standard design a new MCU to meet the SIG specification. The nrf52840 and nrf52832 introduced by Nordic and the CC2640R2F launched by TI Semiconductor support Bluetooth 5.0. From the perspective of hardware characteristics, the CC2640R2F has 10 times lower overall sleep power consumption than Nordic's nrf52840 and nrf52832.
Prompt:
After power on, there will be a tone waiting for Bluetooth connection, and the power indicator will flash quickly. When Bluetooth is connected, a tone will tell you that the Bluetooth connection is successful, and the power indicator will stop blinking. The indicator flashes at low frequencies during song playback.
Three audio input methods:
Support Bluetooth, TF card, AUX audio input. This power amplifier does not support three simultaneous input modes, the system will automatically select the audio input mode of the last input. (For example, when playing a song in a TF card, you are inserting AUX, the system defaults you to modify the input method, select AUX input)
During AUX input: the power light is always red and the blue light is blinking.
When the TF card is input: the power light is always red and the blue light is blinking.
During Bluetooth input: The power light is always red, the Bluetooth light is always on when the Bluetooth connection is successful, and it flashes when playing songs.
On-board volume adjustment:
Two volume adjustment methods, such as picture display. Use the wire to short the small hole in the board to adjust the volume of the audio input. The "+" and the small hole in the middle can be shorted for a long time to increase the volume, and short time to short a song. "-" And the middle hole are short-circuited for a long time to reduce the volume, and short-time to the next song. The onboard volume adjustment potentiometer can adjust the volume of the amplifier. Turn it clockwise to increase the volume, and turn it counterclockwise to decrease the volume.
Note: The current notification tone of Bluetooth connection is in Chinese, but it does not affect normal use. If you mind, please do not buy!
