11.Frequently Asked Questions:
1.How to choose a power supply adapter?
Q: The power supply of the module is very critical. The user must pay enough attention to the power supply. Otherwise it may not work properly. The ripple of the selected power supply must be small. A power supply with a large ripple will cause the background noise of the power amplifier board to become larger and there will be current sound.
It needs 5.5*2.1mm or 5.5*2.5mm power adapter and it is recommended to use 12V/24V power supply with current more than 2A.
The higher the voltage and the higher the current then the better the output power. It is better to connect 4ohm speaker if the power voltage less then 21V. It is recommended to use 24V voltage if use 8ohm speaker. It will be damaged if input voltage is more than 24V.
If the voltage is too low, the sound will be distorted after the sound is amplified.
If the current is too small, the speaker cannot be driven to work or the speaker will pull the voltage low and resulting in abnormal operation or poor sound quality.
Adjust the volume to the maximum may be distorted and affecting the sound quality if input low power adapter such as 9V/12V or 1A/2A adapter.
2.How to choose a speaker?
Q:Commonly used speakers are generally 4ohm~8ohm.The speaker no need distinguish between positive and negative polarity.
The speakers need to be connected to full-range speakers or high-frequency speakers and the power is between 10W~100W. The rated power is 50W*2.
It can also work properly if the speaker has low power such as 20W~50W. But it needs connect to low power adapter such as less than 15V to prevent damage to the speaker.
User don't have to worry about the problem of the speaker burning out if connect to 50W~100W speaker.Module can connect 12V~24V.The higher the voltage selected, the greater the sound or power that can be output. Speaker power cannot exceed 100W, otherwise it will affect the sound quality.
3.How to choose Bluetooth or AUX audio input mode?
Q: AUX/USB mode has priority over Bluetooth mode.User need disconnect AUX or USB if use Bluetooth as input audio signal. The priority of connecting first is high for AUX and USB.
4.Why is the volume working normally when volume small and there is turbidity after increase volume?
Q: Sound distortion.Please change the adapter power supply with higher voltage and current. Or decrease the volume.
5.Why is the volume working normally when volume small and there is pause after increase volume?
Q: The input power is insufficient.Please change the adapter power supply with higher voltage and current.
Power supply itself intermittent power-off protection.Please change a match power adapter.
The power of the power supply is too large so please reduce the power of the input power.
The power amplifier board is seriously heated resulting in trigger overheat protection.So please increase the radiator.
6.What factors are related to the sound quality?
Q:The sound quality is not only related to the power amplifier module but also related to the power supply, sound source and the entire sound system.
Basically every factor of the sound system will affect the sound quality. The main factors include the audio transmission line, audio power supply, tone circuit, power amplifier circuit, speaker and surrounding environment.
The sound quality is the best when the sound source, power supply, power amplifier module and speaker match.
