ZK-TB21 Bluetooth Amplifier Board Input Voltage: DC 12V-24V Max Power Output: 50W*2?R&L?+100W?Subwoofer? Input Method: Bluetooth & AUX Channel: 2.1 CH Stereo Output Output Impedance?4-8? Bluetooth Version?BT 5.0 Protection Functions: Reverse Connection Protection Short Circuit Protection Self-recovery Overheat Protection Size: 120*100*22mm Weight: 195g NOTE: Only when the audio input is sufficient and the power supply voltage/current input is sufficient, can there be enough power output. The higher the power supply voltage, the greater the output power; The smaller the impedance of the speaker, the greater the output power. It is recommended to use a 4? speaker. Finally, please make sure that the power of the adapted power supply is greater than the actual working power of the AMP to ensure the maximum output power. Warm Reminder: The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power.
