ZK-MT21 50W x 2+100W 2.1 Channel Bluetooth Digital Amplifier Module

Overview & Features

. Bluetooth version: 5.0 (unobstructed, 15 meters). Input sensitivity: 500mV. Input mode: AUX+Bluetooth. Number of power channels: 2.1 channels. Adaptable speaker: 20-100W, 4-8 ohms. Protection mechanism: anti-reverse connection, overheating and overcurrent, short circuit protection. Adaptable power supply: DC 12-24V/5A or above (cannot be connected to 24V battery pack). Output power: less than 50W for left and right channel, less than 100W for subwoofer. Size: about 9.3 x 9 x 2.2cm. Weight: about 185g (including packaging).. Tip: In the case of enough audio input, enough power supply voltage/current, there will be enough output power, the higher the power supply voltage the higher the output power, the lower the impedance of the speaker the higher the output power, please make sure that the adapted power supply power is greater than the actual working power of the amplifier..
