product description: 100W Subwoofer can be changed to full-range power amplifier Product power and signal lines need to be purchased separately Please note that no power adapter Digital amplifier can do standard monaural amplifier board can also do subwoofer amplifier board, with the front op amp NE5532 buffer match. Than the market did not drive the TPA3116 level better. Delivery is the default subwoofer amplifier board, if you want the whole frequency, you can tell us that we will send the whole frequency of delivery Turn left to the bottom of the knob is off Amplifier Overall dimensions: 68.5X33X90mm (without knob and rear terminal) Different from the TAOBAO cheap to sell and sell digital power amplifier, low cost can not play the performance of TPA3116, our key components used 2-3 times the material to customize, regardless of performance or price is very good. 100W Is the use of the new US TI TPA3116D2 high-performance amplifier chip as the core, DC single power supply 8-25V wide operating voltage, 50W (left channel) +50 W (right channel) dual-channel output, the efficiency of up to 90%. Can use switching power supply, laptop switching power supply, battery or car power supply and so on … Optional with power supply: The power interface is the standard 5.5MM power jack, and most of the same notebook power Power use: 8-25V Note: To have enough output power when the audio input is sufficient and the supply voltage / current is sufficient. The power supply voltage is higher than the relative power will be larger, different impedance of the speaker will have a different output power. In the case of sufficient voltage and current, the greater the number of horns, the relative sound power is smaller, please pay attention! Precautions: normal operation is to connect the external power supply and digital power amplifier interface, and then to the external power supply 220V power cord into the electricity outlet. Wrong approach is to connect the external power supply of the mains interface, and then go to the external power supply output interface input to the digital amplifier, because the digital amplifier has a filter capacitor, so that capacitor charge and discharge, contact 0.1 seconds to produce low pressure sparks. Although the low pressure did not have any effect, but also a bad habit. Some users if the hand voltage is lower than 12V, want to get a strong power, you can increase the pressure board, the voltage increases, so that power and tone improvement are considerable PHOTOLIST: Aftermarket commitments:
