HIFI Level with Filter Digital Power Amplifier Board Module - 502C HIFI

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.With AUX and BT two ways of audio input 2-in-1.The potentiometer with a switch for easy control of the volume making it ideal for DIY speakers.Filter inductor makes the sound mellow and clearer.Integrated self-protection circuits including over-temperature short circuit over-voltage and under-voltage.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.Note: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.Specifications:Material: ABSColor: BlackModel: ZK-502C HIFIChip: TPA3116D2(with AM avoidance)BT version: 5.0Output power: 50W x 2Allowable supply voltage: 5~27V (optional 9V/12V/15V/18V/24V adapter high power for high voltage)Compatible speaker: 30W-200W 4? 8?Number of channels: left and right dual channel(stereo)Transmission distance: 15 meters (without barrier)Protection measure: over-temperature short circuit over-voltage and under-voltagePower 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 55+ 55WItem Size: 9.8 * 5 * 1.5cm / 3.85 * 1.96 * 0.59inItem Weight: 46g / 1.62ozPackage Weight: 115g / 4.05ozPackage Size: 11 * 6.5 * 5cm / 4.33 * 2.55 * 1.96inPacking List:1 * Amplifier Module1 * Heat Sink1 * Screwdriver1 * DC lead1 * Shell1 * Knob
