If You Have Any Questions About The Product, or The Product Has Quality Problems, Please Contact Us At Any Time, We Will Give You A 100% Satisfactory Answer Product Description How many signal input methods does it have? Bluetooth & AUX ! When these two input methods input signals at the same time, the Bluetooth input method is the priority input method. If you want to use AUX, please disconnect the Bluetooth connection. Chip: TPA3116D2 Input Mode: Bluetooth / 3.5mm AUX Work Voltage: DC 12V-24V Channel: 2.1 CH Stereo Output Bluetooth Version: Bluetooth 5.0 Bluetooth Transmission Distance: 50 Ft MAX Power Output: 50W*2（R&L）+100W（Subwoofer） Terminating Impedance: 4 - 8 Ohm Match Speaker: 50 - 300 watt Work Humidity: 0%~95%RH Packing Include ZK-TB21 Power Amplifier Board * 1 Protective Shell * 1 Set DC Plug * 1 Screwdriver * 1 Knob * 5 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. Dual TPA3116 D2 Chip 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% 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. Is it durable? This is beyond doubt! This amp board has 4 kinds of protection mechanisms: overvoltage protection, undervoltage protection, overheat protection, short circuit protection, which means it is not easy to be damaged! 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.
