Product description How to Select the Audio Input Mode This amplifier board has two input modes: Bluetooth and 3.5mm AUX. When both modes input audio signals at the same time, the amplifier board will give priority to the Bluetooth mode; If you need to use the AUX mode, please make sure that the Bluetooth connection is disconnected. 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 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. Independent Control of Treble and Bass The bass audio and volume can be adjusted separately, and with the left and right channel speakers, the 2.1 channel brings you a richer sound experience. Dual TPA3116 D2 Amplifier IC The maximum modulation frequency can reach 1.2MHZ, and the high-power output distortion is less than 0.1%, ensuring high-quality sound output. 50*25*10MM Extra-large Heat Sink The extra-large heat sink can provide good heat dissipation for the continuous high-power output of the AMP, thus preventing the chip from being burned. 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.It is recommended to use a power supply of 12-24V, 5A or more, and the speaker power is 50-100W for the best effect!It is recommended not to use storage battery power.
