Mini Bluetooth Amplifier Board, 100W+100W 2 Channel BT 5.0 Stereo Audio Receiver Amplifier Board Digital Module Amp for Home Passive Speakers - DiGiYes ZK-1002L

• 2 Channel stereo output power 100w x2, working voltage range DC 5-24V, for 4-8 Ohm 50watt-300watt passive speakers. Using copper DC connectors, it can withstand high current and does not generate heat. Large volume black metal heat sink ensures efficient heat dissipation. A solid state capacitor with 4 x 470uf capacitors ensure power storage capacity, and continuous stable power supply is a prerequisite for good sound effect. ZK-1002L amplifier board has a bottom plate and a top plate, support reverse connection protection, over-voltage protection, under-voltage protection, over-heat protection, short-circuit protection. The potentiometer adjusts the volume with a switch, which controls the volume and is very suitable for DIY speakers. 5.0 Bluetooth version, with higher transmission efficiency and longer transmission distance. NOTE: Please use the compatible power supply to avoid the safety concern. The work voltage for model ZK-1002L is DC 5V-24V. So the compatible power supply output voltage can't exceed 24V.
