Audio Level Amp with VU Meter and Backlight

The VU (Volume Unit) Meter features the following specifications:

Material: Plastic, metal, and electronic components Color: As shown in the picture Size: Approximately 35 * 35 * 37mm / 1.38 * 1.38 * 1.46 inches

Measuring Range: 0-500UA ± 10% Resistance: 650Ω ± 10% Accuracy: ± 5% Approved Location: Full-scale 500UA

Backlight Voltage: AC/DC 6-12V

Driver Board: The fourth-generation driver board has been further refined in size. It utilizes an improved drive plate instead of the Toshiba 7318IC, addressing the disadvantages of the 7318: 1) small plate pointer swing, and 2) low sensitivity regulation.

Package Content: - 2 x VU Panel Meter - 1 x Driver Module - 1 x Cable

The driver board features low-level signal input terminals for connections to devices such as CD players, computer sound cards, and other audio signal source devices. The wiring is labeled as follows: L (Left channel), GND (Ground), and R (Right channel).

Power Consumption: The driver plate requires a power supply of 12V-15V AC/DC. (It is recommended to use an independent power transformer or a separate power supply for the winding.) The backlight current is 45 mA when the driver plate is not in use.

Adjustable Resistors: The driver board has two adjustable resistors, R1 and R2, which can control the size of the meter's pointer swing.

Rectifier Regulator: The backlight DC12V power meter uses a rectifier regulator for the backlight driver board. Please ensure the correct polarity of the positive and negative head interface.
