Product Description
How many signal input methods does it have?
Three input methods!（USB、AUX、Bluetooth).When these three input methods input audio signals at the same time, their priority order is USB→AUX→Bluetooth. In other words, if you want to use AUX, you need to disconnect the USB input audio; if you want to use the Bluetooth mode, you need to disconnect both the USB connection and the AUX connection.
Warm reminder: The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power.

Large Heat SinkThe heat sink can provide a good heat dissipation effect for the continuous high power output of the AMP, so as to avoid the chip from being burned out. | TPA3116D2 ChipLaunched by TI, with very high index parameters. The highest modulation frequency can reach 1.2MHZ, and the high-power output distortion is less than 0.1% | Multiple Input MethodsIt has a variety of audio input methods: Bluetooth/AUX/USB flash drive/USB sound card, you can choose the way you like to connect! |
TIP
- Only when the audio input is sufficient and the power supply/current is sufficient, there will be enough output power.
- If the power supply voltage is higher, the relative power will be higher. Speakers with different impedances will have different output powers.
- In the case of sufficient voltage and current, the larger the ohmic number of the speaker, the smaller the relative sound power!
