ASUS Xonar DSX
Q6: What is the most important benefit of the Xonar DSX for musicians?
Answer:
1. Ultimate Fidelity: Xonar DSX has the highest quality of audio in/out for the
cleanest sound production.
2. Duplex HD: Supports audio sampling rates up to 24bit/192KHz for output and
24bit/96KHz for input.
3. ASIO 2.0: Xonar DSX includes an ASIO 2.0 driver for low-latency, low-
distortion music creation application.
Q7: Is PCM sound output through S/PDIF limited to 2-channels even with
different analog output channels?
Answer:
The S/PDIF protocol specification (IEC-60958) can only carry 2-channel PCM
data or non-PCM AC3/DTS data. When a user selects PCM output for S/PDIF,
the Xonar sound card will always deliver 2-channel PCM data through the S/PDIF
output port. For attaining 5.1 channel surround sounds, you can select DTS
Interactive encoding output from the S/PDIF out menu, which will allow the Xonar
DSX to deliver up to 7.1 surround sound for games, DVD movies, and even stereo
music.
Q8: Why can I hear and record sound from other recording devices when
Wave/Digital is selected in Record on Windows
®
Vista?
Answer:
Unlike Windows
®
XP, Windows
®
Vista manages multiple audio devices and audio
streams, identifying them as either digital input or analog input. This system allows
for multiple recording devices to run simultaneously in Windows
®
Vista. Wave In or
SPDIF-In, considered as a digital input, is an independent recording device from
Analog Devices such as Mic In, Line In, or Aux In. Therefore, if you have analog
input other than Wave In in use and set to be monitored, you are able to hear
and even record sound from those analog devices even if Wave In / SPDIF-In is
selected as the default recording device.
Turn off the monitoring function for analog input devices if you only prefer to hear
and record Wave In / SPDIF-In sound.
Q9: Why are sound effects not available when playing 96K or 192KHz sound
sources?
Answer:
The sound effects feature on the Xonar DSX currently supports standard 44.1K
and 48KHz sound sources. However, users are assured of high fidelity playback
for 96K sound sources. This is the common setup professional audiophiles and
musicians prefer.
