The HD Audio Center is an excellent device for converting digital and analog audio
sources. It allows for simultaneous conversion of a digital or an analog audio input to all
digital and analog audio outputs. Featuring a sampling rate converter to 44.1 kHz ~ 192
kHz (up to 24-bit) output, supports LPCM 2CH audio, HDMI, USB Audio 2.0, Optical and
Coaxial digital input/output.
For professionals, the Ti TPA6120A2 headphone amplifier, XLR (Low-noise Professional
Balanced output) and 6.3mm headphone jack (3.5 mini-jack adaptor supplied) offer
unparalleled audio quality. With a highly accurate PLL and low jitter reduction clock
system and an OLED display and IR remote for controlling the device, the HD Audio
Center is an incredibly useful tool for getting the most out of your audio devices.
