HIFI Power Amplifier Board Module 50Wx2 AUX and BT5.0 Audio - ZK-502T

This power amplifier is equipped with TPA3116D2 a high quality chip with AM avoidance. Its treble and bass control and volume control feature low distortion and wide adjustment range delivering high performance and making it convenient to use.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.It has treble and bass adjustment which can be controlled independently.Integrated self-protection circuits including over-temperature short circuit over-voltage and under-voltage DC detection.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: ZK-502TChip: TPA3116D2(with AM avoidance)BT version: 5.0Output power: 50W x 2SNR: ?90 dBAudio Input: AUX + BTChannel: 2.0(stereo)Allowable supply voltage: DC9~24V / 2A higher (high power for high voltage)Compatible speaker: 15W~100W 4?~8?Transmission distance: 10 meters (without barrier)Protection measure: over-temperature short circuit over-voltage and under-voltage DC detection.Output Power: 15W*2 @12V 8? 30w*2 @12V 4? 20W*2 @19V 8? 40W*2 @19V 4? 30W*2 @24V 8? 50W*2 @24V 4?Item Size: 11 * 7 * 2cm / 4.33 * 2.76 * 0.83inItem Weight: 65g / 2.29ozPackage Weight: 155g / 5.46ozPackage Size: 13 * 8.3 * 4.5cm / 5.11 * 3.26 * 1.77inNote: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.Please make sure the supply power is greater than the actual working power of the amplifier.Packing List:1 * Amplifier Module1 * Heat Sink1 * Screwdriver1 * DC lead1 * Shell1 * Knob
