Overview
High quality sound DAC + headphone amplifier supporting DSD 5.6MHz / PCM 192kHz for easy high-resolution experience via USB bus power.
Features
- Operates on USB bus power.
- Linear PCM audio up to 24bit/192kHz and DSD audio up to 5.6MHz can be played back.
- DSD audio playback requires DSD-compatible playback software on a PC. This unit supports DoP and ASIO methods.
- HI/LO gain switching (10dB) supports a wide range of headphones.
- Asynchronous mode (asynchronous mode) using a custom crystal (crystal oscillator) is adopted.
- Digital filter with roll-off characteristics and cut-off frequency that can be switched according to the sound source.
- High-quality sound DAC (Burr Brown PCM1792A).
- USB Audio Class 2.0 compatible.
- Compatible with Windows XP (SP2 or later)/Vista/7/8/8.1/10 and MacOSX10.6 or later.
