XH-M567 TPA3116D2 12 to 24V DC Dual Channel 2 x 80W Audio Power Amplifier Module

XH-M567 TPA3116D2 12 to 24V DC Dual Channel 2 x 80W Audio Power Amplifier Module is a High And Low Adjust Onboard Operational Amplifier. It has high-efficiency class D operation, with > 90% power efficiency and low idle loss characteristics, advanced modulation system configuration, multiple switching frequencies, and AM interference prevention.

The TPA3116D2 advanced oscillator / PLL circuit uses multiple switching frequency options to suppress AM interference. When used with the master-slave mode option, multiple devices can also be synchronized. The TPA3116D2 device provides comprehensive protection against short circuit, overheating, overvoltage, under-voltage and DC faults. In the event of an overload condition, the device reports the fault condition to the processor, thereby avoiding its own damage.

Tips:

Power amplifiers can be noisy in some cases. Here are some common reasons

1. Hardware problem:

• The power supply is unstable, or the power supply module generates interference.
• The influence of switching power supply as power supply.
• Using transformer power supply, do not do shielding isolation.
• There are electromagnetic interference in the use of the environment.
• The audio input device itself has problems.

HOW TO SOLVE:

• Power and power amplifier should maintain a certain distance. To avoid electromagnetic interference, it is best to use high quality power supply, power supply will be stable.
• If you use transformers and other power supplies, it is best to use iron cover to prevent electromagnetic interference.

2. Software problem:

• Interference of Audio driver settings
• Interference of Player effects

HOW TO SOLVE:

•  When the power amplifier is connected to the computer or mobile phone, the relevant special effects software or sound card driver special effects can be set off.
• Using special effects to ensure that the output of the power amplifier is not affected.
