Multifunctional amplifier board:Amplify weak signals from the or preamplifier and push the speaker to play Use High-performance capacitors,With pulse intensity,Hiah reliability,Good self-healing<br><br>Model: -1C060 V1.1 : 92dB Input mode: AUX Channels:Mono Channel Amplifier Chip: TPA3118 (Chip) Power Supply: DC12-24V Adapter Horn: 4-8Ω Output Power: 1x60W Note: 1.The higher the voltage, the louder the sound. Please give up this misconception. Only the right power supply and the right speakers can produce perfect sound. 2.The power supply and speakers determine the output power of the amplifier. 3.Our power amplifier input generally requires 1.5V-2V. If your decoding output is 500mV-1V, that is not enough. Even if your power supply and speaker are adapted, the power amplifier output cannot reach 2x100W. 4.32Pin TPA3118 power amplifier chip.
