Product Description ZK-TB21 Bluetooth Amplifier Board Input Voltage: DC 12V-24VMax Power Output: 50W*2（R&L）+100W（Subwoofer）Input Method: Bluetooth & AUXChannel: 2.1 CH Stereo OutputOutput Impedance：4-8ΩBluetooth Version：BT 5.0Protection Functions: Reverse Connection Protection Short Circuit Protection Self-recovery Overheat ProtectionSize: 120*100*22mmWeight: 195g TPA3116 D2 Is A Class D Power Amplifier IC Launched by TI, with very high index parameters. The highest modulation frequency can reach 1.2MHZ, and the high-power output distortion is less than 0.1% 50*25*10MM Large Heat Sink The large heat sink can provide good heat dissipation effect for the continuous high-power output of AMP, thus avoiding the chip from being burned out. Multiple Power Input Methods High-grade fence terminal-convenient wiring, not easy to short circuit; Two power input methods can meet your different wiring needs. 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 4Ω 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.
