XDA-3 DAC
Differential Reference
5. HDMI ARC (Digital) Input
Use this input to connect the XDA-3 to the ARC (Audio Return Channel) output of a TV set or
projector. The XDA-3 is a STEREO DAC and so will only accept a stereo audio input.
See the section entitled Using The HDMI ARC Input for more details.
Note: The HDMI-ARC connection on your TV is intended to deliver a digital audio OUTPUT to
an AVR or preamp/processor when the audio source is either an App running on your TV or
a device connected directly to one of the other inputs on your TV. HOWEVER, EVEN THOUGH
YOU WILL BE USING THE HDMI-ARC CONNECTION ON YOUR TV TO OUTPUT A DIGITAL AUDIO
SIGNAL, BECAUSE THAT CONNECTION IS ALSO NORMALLY USED TO INPUT A VIDEO SIGNAL TO
THE TV, IT WILL BE LABELED ON YOUR TV AS AN "HDMI-CEC INPUT" or "HDMI/ARC INPUT".
Note: The HDMI-ARC connection between your TV and the XDA-3 uses an ordinary HDMI cable.
This connection does not require a high speed HDMI cable. HOWEVER, BE SURE TO USE AN
HDMI CABLE THAT INCLUDES AN ARC CONNECTION, WHICH VIRTUALLY ALL MODERN HDMI
CABLES INCLUDE. IF YOU PLAN TO USE A SPECIAL POWERED HDMI CABLE OR OTHER TYPE OF
HDMI EXTENDER, BE SURE THAT IT ALSO SUPPORTS ARC. ALSO NOTE THAT, WHILE WE EXPECT
HDMI-ARC ON THE XDA-3 TO WORK WITH MOST POWERED CABLES AND EXTENDERS THAT
SUPPORT ARC, WE CANNOT PROMISE THAT IT WILL, AND CANNOT PROVIDE SUPPORT IF YOU
ARE UNABLE TO GET IT TO WORK.
6. Optical 1 & Optical 2 Toslink Optical S/PDIF (Digital) Inputs
Coaxial 1 & Coaxial 2 Electrical S/PDIF (Digital) Inputs
These inputs accept optical S/PDIF (Toslink) and electrical S/PDIF (Coax) digital audio signals, in
stereo PCM format, at sample rates up to 192k and bit depths up to 24 bits.
Note: The XDA-3 is a stereo PCM DAC and only accepts STEREO PCM digital audio signals. The
XDA-3 CANNOT decode DTS, Dolby Digital, or other surround sound audio formats.
Note: For computer-based sources, or other source devices that support either higher sample
rates, or other formats like DSD, use the USB Digital Audio input.
Note: If you attempt to play DTS-encoded audio files on some equipment that doesn't recognize
DTS encoding, the undecoded DTS audio files may be sent to the XDA-3, which may result in an
unpleasant digital screeching noise. (This will not harm anything, but suggests that your source
equipment either cannot properly process DTS-encoded files, or is not configured correctly to
do so.)
6. Trigger Input & Trigger Output
The Trigger Input will enable the XDA-3 to be turned on by a trigger signal from another piece
of trigger-enabled gear. The Trigger Output on the XDA-3 will enable the XDA-3 to turn on other
trigger-enabled gear. The Trigger Output on the XDA-3 is active when the XDA-3 is On.
Note: The XDA-3 can only be turned on by a trigger signal if it is in Standby Mode. The
XDA-3 will NOT respond to a trigger signal if the rear panel AC Power Switch is Off.
