Note: The time function can be turned off. Press two buttons simultaneously to turn off.

Function of buttons and sockets:

Key 1: When the frequency spectrum is displayed, the switch drops floating point; when the time is set, adjust the increase time.
Button 2: When displaying the frequency spectrum, switch between single and dual channels; when displaying the time, enter the time setting.
Button 3: Input audio sensitivity (clockwise increase, counterclockwise decrease).

Interface 4: Audio jack (the two jacks are connected)
Interface 5: 5V power jack (micro USB interface)
Interface 6: 12V power jack
Note: This product supports two power supply voltages, choose one to use.

When there is no music, the clock is displayed; when there is music, the spectrum is displayed.

Shared power connection：

Shared power means that the power supply for the power amplifier and the spectrum power supply are the same.
The shared power supply does not need to be connected to the GND line.
When connecting the power supply, make sure that the power supply voltage is within the allowable range of the spectrum.

Independent power connection：

Independent power supply means that the spectrum and the power amplifier use two different power supplies.
The independent power supply needs to be connected to the GND of the output terminal of the power amplifier.
The GND here is the GND of the output terminal of the power amplifier, not the ground terminal of the household AC power.

Type B is only the shell. The following is the effect of installing the shell. Customers who need the shell should take a picture of the shell together. The shell needs to be installed by yourself, which is very simple.

The time is displayed when there is no music, and the spectrum is displayed when there is music.
