Douk Audio VU3 Dual Analog VU Meter 2-Way Amplifier/Speaker Audio Switcher Box DB Panel Display

The VU3 VU meter and audio switcher box was originally designed by DoukAudio. As a VU meter, it features dual 60*35mm large meters, dynamically enhancing audio and providing unparalleled visual effects when switching audio signals. The VU2's USB interface is used to power the VU meter's drive board and does not interfere with the audio input and output circuits. The VU meter and switcher box are controlled independently, and the VU meter only reads audio signals from the I/O interface, so sound quality is not affected. Powerful design and strong compatibility: All channels feature a fully isolated design, and the GND of each channel is independent and eliminates mutual interference. It is compatible with all types of amplifiers, including BTL, Class A, Class B, and Class D digital amplifiers, as well as vacuum tube amplifiers.
