AIYIMA A03 TPA3116 Subwoofer Bluetooth Amplifier HiFi TPA3116D2 Channel Digital Audio Amplifier 2.1 50W2+100W DC12-24V

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Normal signal lines require shielding. It is recommended that you test the signal lines as much as possible. Even with a very good signal line, it still gets in the way when you are using your cell phone as a signal source. About the signal source The most commonly used signal sources are mobile phones and computers. The quality of audio signals output by mobile phones and computers according to different brand models is also different. Generally speaking, if the quality of the audio signal coming directly from your computer's motherboard is relatively poor, you won't hear it at low volumes, but it will become obvious after you amplify it. If you are not satisfied with the sound quality of the computer itself, you can purchase a USB decoder (equivalent to an external USB sound card) from the store to improve the sound source and significantly reduce noise. Determining the source of the noise is relatively simple. Do not enter any input signal, turn up the amplifier volume, or listen to speaker noise. If there is no noise, the noise comes from the source or signal line. Package Included: 1PC TPA3116 2.1 Bluetooth Digital Amplifier (No Power Supply)
