35mm VU Meter Audio Level Indicator Kit with Backlight & Driver Board

• Product Information: This kit adopts the mature 5th generation front-level driver board plus classic backlight 35mm VU meter head, with driver board, suitable for telephone, computer, preamplifier, Mp3. VU meter backlight voltage: AC6V-12V DC current; 500uA +-15% DC internal resistance: 650 ohm + -15% Working temperature: -22%-55 degrees Celsius
• L, G, R: These are the dual-channel input terminals of the driver circuit board. They can be connected to the audio and power amplifier output terminals of audio source devices such as mobile phones, computer sound cards, and preamplifiers for signal intake. When wiring, L, G, and R should be respectively connected to the left, ground, and right channels of the audio source device
• Attention: Do not connect the output DC12V backlight voltage to the wrong VU meter when connecting the cable, because the current will burn out the meter head. It cannot be connected to the output of the power amplifier, including the car CD player.
• The adjustable potentiometer "100R-V" is used to adjust the brightness of the backlight of the VU meter. The adjustable potentiometers "50k-1" and "50k-2" respectively control the pointer jumping amplitude of VU Meter 1 and VU meter 2.

Product Information:

This kit adopts the mature 5th generation front-level driver board plus classic backlight 35mm VU meter head, with driver board, suitable for telephone, computer, preamplifier, Mp3.

VU meter backlight voltage: AC6V-12V

DC current; 500uA +-15%

DC internal resistance: 650 ohm + -15%

Working temperature: -22%-55 degrees Celsius

L, G, R: These are the dual-channel input terminals of the driver circuit board. They can be connected to the audio and power amplifier output terminals of audio source devices such as mobile phones, computer sound cards, and preamplifiers for signal intake. When wiring, L, G, and R should be respectively connected to the left, ground, and right channels of the audio source device,If the input is from a mobile phone, computer sound card, preamplifier or other audio sources, please turn the dip switches 1 and 3 to the "ON" terminal. If the input is from the output terminal of the power amplifier, please turn the dip switches 2 and 4 to the "ON" terminal. The signal will be compressed by 11 times. Note: The dip switches from 1 to 4 should not all be set to the "ON" position simultaneously.

Attention: Do not connect the output DC12V backlight voltage to the wrong VU meter when connecting the cable, because the current will burn out the meter head. It cannot be connected to the output of the power amplifier, including the car CD player.

The adjustable potentiometer "100R-V" is used to adjust the brightness of the backlight of the VU meter. The adjustable potentiometers "50k-1" and "50k-2" respectively control the pointer jumping amplitude of VU Meter 1 and VU meter 2.
