Product parameter

Product name: 50W*2 Bluetooth 5.0 audio power amplifier moduleProduct model: ZK-502DBluetooth version: 5.0 (unobstructed, 15 meters)Signal to noise ratio: >95 dBInput method: USB + AUX + BLUETOOTHNumber of channels: left and right dual channels (stereo)Power amplifier chip: TPA3116D2 (with AM interference suppression function)Adapter power supply: DC 9~24 V/2A or more (the higher the voltage, the greater the output power)Adapted speakers: 15~100W, 4~8QOutput power: 15W*2 @12V,8Q30W*2 @12V,4Q20W*2@19V,8Q40W*2 @19V,4Q30w*2 @24V,8Q50W*2 @24V,4QProtection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protectionProduct size: 80mm*77mm*22mmhint:When the audio input is enough and the power supply voltage/current is enough, there will be enough output power!!!The higher the power supply voltage, the greater the output power, the smaller the speaker impedance, the greater the output power!!!Please make sure that the power of the adaptor is greater than the actual working power of the amplifier!!!
