z1 :
Multi LPCM signals are output when “BD Audio Mode” is set to “Mix Audio Output ” (vpage 33).
Multi LPCM signals are output when outputting HDMI video signals with resolutions of 480i/576i or
480p/576p.
z2 :
Super Audio CD audio signals are output at 44.1 kHz 16-bit.
Even if “HDMI Setup” – “Audio Setup” on the GUI menu is set to “Auto” (vpage 25), multilinear PCM
or downmixed 2-channel linear PCM signals are output if a device that does not support bitstreams is
connected.
Copyright protection system
In order to play back digital video and audio such as BD-Video or DVD-Video via HDMI connection,
both the player and TV or the AV Amp need to support the copyright protection system known as
HDCP（High-bandwidth Digital Content Protection System). HDCP is copyright protection technology
comprised of data encryption and authentication of the connected AV device. The DVD-A1UD
supports HDCP.
NOTE
If a device that does not support HDCP is connected, video and audio are not output correctly. Read the
owner’s manual of your television or AV Amp for more information.
The audio signal from the HDMI output terminal (sampling frequency, number of channels, etc.) may
be limited by the HDMI audio specications of the connected device regarding permissible inputs. For
example, if the HDMI audio specication of the connected device is 5.1 channels, 5.1-channel audio will
be automatically output even when playing back 7.1 channels by the DVD-A1UD. In this case, analog
audio output will also be 5.1-channel.
Audio signal input may not be supported depending on the HDMI compatible monitor (projector, etc.)
being used.
When the DVD-A1UD is connected to this kind of device, audio signals are not output from the HDMI
terminal.
