Mini Digital Power Amplifier Board Module with Audio Filter - 1002L mini

This is a cost-effective audio power amplifier specially designed for HIFI sound. Good quality with affordable price.Features:Made of good materials delivers high performance. A cost-effective power amplifier for HIFI music.Employ TPA3116D2 a Class-D stereo amplifier IC with high performance. The modulation frequency can be up to 1.2MHZ and 90% power efficiency combined with low idle loss greatly reduces heat sink size.Equipped with BT 5.0 transmit farther and more efficiently.The potentiometer with a switch for easy control of the volume making it ideal for DIY speakers.Integrated self-protection circuits including over-temperature and short circuit.Comes with DC lead compatible with the power input interface of this product even if you don't have a DC adapter or battery it can be easily wired.Specifications:Material: ABSColor: BlackModel: 1002L miniBT version: 5.0Chip: TPA3116D2(with AM avoidance)Output power: 100W x 2Allowable supply voltage: 5~24V (optional 9V/12V/15V/18V/24V adapter high power for high voltage)Compatible speaker: 50W-300W 4? 8?Number of channels: left and right dual channel(stereo)Transmission distance: 15 meters (without barrier)Protection measure: overheat protection short circuit protectionPower supply voltage: 12V 8? speaker/12W (left channel) + 12W (right channel) 4? speaker/20W +20W15V 8?/18 +18W 4?/ greater than 30 + 30W19V 8?/32 + 32W 4?/ greater than 45 +45W24V 8?/38 + 38W 4?/ greater than 50+ 50WItem Size: 6.8 * 5.2 * 1.6cm / 2.67 * 2.04 * 0.62inItem Weight: 47g / 1.65ozPackage Weight: 111g / 3.91ozPackage Size: 11 * 6.5 * 5cm / 4.33 * 2.55 * 1.96inNote:1. Only when the audio input is sufficient and the power supply voltage/current is sufficient will there be enough output power. The higher the power supply voltage the higher the relative power. The speaker with different impedance will have different output power. In the case of sufficient voltage and current the larger the ohm of speaker the smaller the relative sound power.2. The switch on the board is for control of standby mode. When turn off the switch the unit is in a low-power standby state. If you want to completely turn it off or you may not use it for a long time you can just unplug the DC cable.3. The heat sink needs to be pasted onto the chip by yourself. The hotter the glue the better the thermal conductivity.Packing List:1 * Amplifier Module1 * Heat Sink1 * Screwdriver1 * DC lead1 * Shell1 * Knob
