TPA3116 Amplificador Subwoofer Audio Bluetooth Sound Amplifier 2.1 50Wx2100W HiFi TPA3116D2 Digital Power Home AmplifierA03 Silver

Note: TPA3116D2 send from China Recently, some customers reported that AIYIMA A03 with tpa3156 instead of tpa3116 amplifier . So we checked our current domestic inventory, and indeed there are the same problems. During this time we have been looking for the cause of this problem. Some customers Feekback that the power of the TPA3116 of A03 is not enough, so we adopt TPA3156 to up03. Recently, a customer customized A03 with TPA3116 . However, our warehouse accidentally mixed the A03 with TPA3156 and this customer-made A03 with TPA3116 when they are packing . So there is a phenomenon that A03 power amplifier has both s TPA3156 and TPA3116. At present, our company's domestic warehouse inventory is TPA3156, but the Ruian warehouse and German warehouse have both TPA3116 s and TPA3156 s. TPA3156 is functionally ahead of TPA3116. Panasonic's ECQV1H684 laminated layer cake film capacitor, excellent performance, Japanese power amplifier, s are very common, the actual hearing is no different from EVOX 684 (Evox Rifa has been acquired by KEMET). Nichicon 25v6800uF VZ is a standard product, while CapXon's 25v5600uf and PH series belong to Low impedance and high ripple current, and the capacity difference is 1200UF and the filtering effect is comparable. As for this case , if you mind receiving upgraded A03 with TPA3156 when you choose buy from Ruia , Spain and Germany , please contact us in time, we will give you a $10 coupon or , and you can buy TPA3116 to replaceit by yourself. Description: 1.Support two input, one AUX input, connect wired analog signal input; another one Bluetooth 5.0 wirele input, can connect with mobile phone, computer and other Bluetooth devices.

About the signal line Signal lines are used to transmit weak small signals, and small signals are more susceptible to interference. A normal signal line is required to have a shield. It is best to test the signal lines as good as poible. Even with very good signal lines, you will still be disturbed when using your mobile 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 sound signal directly from the computer motherboard is relatively poor, it cannot be heard at a small volume, but it will be obvious after the amplifier is amplified. If you are not satisfied with the sound quality of the computer itself, you can purchase a USB (equivalent to an external USB sound card) from the store to improve the sound source and greatly reduce the noise. The method of judging the source of noise is relatively simple. Do not insert the input signal into it, turn the amplifier volume up, and listen to the noise in the speaker. If there is no noise, the noise comes from the source or signal line.

Precautions for use: 1 Do not use audio signal lines These lines are not shielded by themselves. High-frequency noise will be introduced. The louder the potentiometer rotates, the larger the noise will become, and the sound is very good, such as Akihabara. Quiet as deep sea, no whistling 2 The correct order of use is to connect the power supply of the notebook power supply and the power amplifier first, and then let the notebook power supply be connected to the mains. The wrong way is to first connect the laptop power to the mains and then connect the laptop plug to the digital amplifier. Because the digital function has a filter capacitor inside, these will produce a slight low-voltage spark for 0.1 second, although there is no impact on performance, but this way The habit is not good either. 3 Use a power supply with as much current as poible. If you only use 2-3A power supply, the output performance will be greatly limited.

Tip:

To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger thes of the horn, the smaller the relative sound power. Please pay attention!
