Adopting MCU to process the audio signal, better to achieve exponential gain driver, provides ultra-wide input signal auto adjustment, the display effects can be greatly upgraded than the common VU meters in the market.
With auto gain adjustment, very easy to control most input signals and achieve better beating effects. Backlight function can be turned on or turned off, convenient to use, and the bright and warm light can decorate your desktop or live studio.
The circuit layout is rational and compact. The power supply is dedicated to the driver board and VU meter, not the audio input and output circuit. This preserves sound quality while enhancing visual appeal.
With standard stereo L/R RCA input and output, can compatible with most common audio device such as mobile phone, computer, CD players, preamp, power amplifier or studio mixers and so on, suitable for a variety of scenarios.
