XDUOO Balanced DAC Headphone Amplifier DSD64 XA-02 & PCM24bit/192KHz

Balanced output. A truly balanced output from the decoding circuit to the amplifier circuit reduces noise caused by ground wires and channel crosstalk, greatly improving separation and reducing background noise. Balanced class A buffer. Uses transistors as class A buffers to keep the circuit in the best condition at all times, Strong output, strong load capacity, specially designed to drive a variety of headphones. Built-in relay protection. Built-in relay protection function avoids POP noise when powering on and protects the earphones and machine in abnormal situations. Digital volume adjustment. Digital volume adjustment eliminates unbalance at low volumes; Attractive background lights change color with volume. You can check the volume before connecting headphones. Small size. High output, high sound quality, and small size. Today's compact desktop spaces allow smaller machines to be placed on the desktop. Stylish appearance, space gray color, easy to match with your desktop. Parameters: 1.POWER SUPPLY: AC 100-240V 2. SCREEN: 1.3 INCH OLED SCREEN 3.
