s:Product name: 2.1 Bluetooth power amplifier moduleProduct model: ZK-TB21FBluetooth version: 5.0 (bstructed, 10 meters)Input sensitivity: 500mVInput method: AUX+BluetoothNumber of s: 2.1 sPower amplifier chip: TPA3116D2 (with AM interference suppreion function)Adapted power supply: DC12~24V/5A or above (the higher the voltage, the greater the output power)Adapted speaker: 20-100W, 4-8 ΩOutput power: left and right s ≤ 50WSubwoofer ≤ 100wProtection mechanism: overvoltage, undervoltage, overheating, DC , short circuit protection

Tips:Only when the audio input is sufficient and the power supply voltage/current is sufficient can there be sufficient output power.The higher the power supply voltage, the greater the output power, the smaller the horn impedance, and the greater the output power.Please ensure that the power of the adapter power supply is greater than the actual working power of the amplifier.

Package include:Power amplifier module * 1Acceory combination * 1
