This USB DAC operates on USB bus power and supports up to 32bit/192khz. It can be used immediately after connecting the USB cable and performing simple settings.
High-quality sound reproduction can be easily achieved by simply connecting a USB cable to a PC
USB audio and optical digital audio signals from a PC can be converted to analog signals and output from the line output terminal and headphone output terminal. When used as a USB DAC, it operates with the USB Audio 2.0 driver of the PC (Windows or MacOS) and supports up to 32bit/192khz. It can be used immediately after connecting the USB cable and performing simple settings.
ES9016K2M from ESS Technology is used as the DAC chip
The HP-A3 uses a high-quality DAC chip, and the supported sampling frequency has been greatly enhanced from 24bit/96 kHz of the HP-A3 to 32bit/192 kHz. This allows users to enjoy higher quality sound without sacrificing ease of use. S/P DIF input is limited to a maximum of 96 kHz.
Analog circuitry with further improved sound quality
The analog circuitry has been newly designed to match the higher supported sampling frequency, and has improved THD (Total Harmonic Distortion) and other performance features that are comparable to those of higher-end products.
Gain switch added to accommodate various playback sources
The headphone output amplifier gain can now be switched between HI and LO positions, with the HI position providing a 10 dB increase in volume over the LO position. The HI position is effective for low-level input signals and can be used with a variety of playback sources.
