Packing Include:

1 X ZK-TB21 Power Amplifier Board
1 X Protective Shell
1 X DC Plug
1 X Screwdriver
5 X Knob

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.
