Can't Connect to Amplifier Output

Pay special attention not to connect the output DC12V backlight voltage to the wrong VU meter when connecting the line, because the current will burn the meter head

Instructions for use

1. AC12V is the power supply. (It is recommended to use an independent power transformer or independent winding power supply!

2.L, G, R: This is the two-channel input terminal for low-level signal of the driver board, which is used to connect the audio of mobile phones, computer sound card pre-stage, and other audio source devices (the signal is the signal that the earphone can hear). L, GND, and R correspond to the left, ground, and right channels respectively

Note: Can't connect to the power amplifier output Can not connect to the output of the power amplifier. Can not connect to the output of the power amplifier. Including car CD player cannot be used

3 Adjustable resistance "5K-V" is to adjust the brightness of the backlight.

4 Adjustable resistors "50K-1 and 50K-2" respectively control the beating amplitude of the pointers of VU meter 1 and VU meter 2,

Debugging method

1. Level meter debugging Find a signal generator to adjust the output frequency of 1KHz, the effective value of the signal is 0.775V, and then connect the signal input of the drive board, and the pointer of the meter head points to the 0DB of the instrument panel. (If you don't have a signal generator, you can download an APP signal generator with your mobile phone, and you can adjust it according to the previous method)

2. The debugging of the VU meter, the adjustment of the VU meter is much simpler, the driver board is connected to the audio signal, and the driver board can be adjusted.

Adjust the resistance to synchronize the loudness and rhythm of the ear to the sound with the pointer, so that the pointer swings moderately so that the pointer points to the 100% position of the sign or the maximum value of the sign when the sound is maximum.
