Douk Audio VU1 Analog VU Meter, Sound Level Indicator for Amplifier/Preamp

The device features a stereo RCA audio input and stereo RCA audio output. It operates on a working voltage of DC 9-12V, 200mA. The backlight filament voltage is DC/AC 6-12V, with a backlight filament current of 500μA. The VU meter has a diameter of 35mm, and the overall dimensions are 15012040mm / 5.914.721.57in. The net weight is 225g / 0.50lb, and the package weight is 400g / 0.88lb.

It is important to note that the default setting for the GAIN control is 50%, at which position the input voltage of the 0dB position on the VU meter is 0.775Vrms. The VU meter is driven by an exponential gain algorithm, which means that when the input volume is low, the swing amplitude of the pointer is large, and as the volume gradually increases, the swing amplitude becomes smaller.

The device utilizes an MCU to process the audio signal, allowing for an improved exponential gain driver and ultra-wide input signal auto-adjustment, resulting in better display effects compared to common VU meters on the market. The circuit layout is reasonable and concise, with the power supply only providing power to the driver board and VU meter, and not passing through the audio input and output circuit. This ensures that the sound quality is not interfered with, while adding dynamic visual enjoyment.

The auto-gain adjustment feature allows for easy control of most input signals, achieving better beating effects. The backlight function can be turned on or off, providing a convenient and decorative feature for your desktop or live studio. The device is equipped with standard stereo L/R RCA input and output, making it compatible with a variety of common audio devices such as mobile phones, computers, CD players, preamps, power amplifiers, and studio mixers, making it suitable for a wide range of scenarios.

The package contents include 1 VU meter, 1 power supply, and 1 manual, providing everything needed for a complete and functional setup.
