Input frequency is displayed by LED. This USB DAC operates only on USB bus power and can convert USB digital audio output from a PC into high-quality analog audio. Although it uses bus power, it regenerates the PC's noise to prevent it from negatively affecting the audio system using a unique circuit, and rebuilds it with an independent power supply for the internal circuit. It supports inputs up to 24bit/96kHz and eliminates jitter by using asynchronous mode, achieving high sound quality. The power supply and signal circuits are isolated to reduce noise. Frequency response is 20Hz～20kHz, and the S/N ratio is 99dB. External dimensions are 58.5 x 129.6 x 22.3mm (width x depth x height).
