option is set to [DTS re-encode], the audio
output is limited to 48 kHz and 5.1Ch. If the
[HDMI] or [Digital Output (SPDIF)] option is
set to [DTS re-encode], the DTS Re-encode
audio is outputted for BD-ROM discs, and
the original audio is outputted for the other
discs (like [Primary Pass-Thru]).

If [HDMI] option is set to [PCM Multi-CH]
and [Digital Output (SPDIF)] option is set to
[Primary Pass-Thru] while playback Dolby
Digital Plus or TrueHD audio, DIGITAL AUDIO
OUT is limited to “PCM 2ch”.

If the HDMI connection is version 1.3
and Dolby Digital Plus/Dolby TrueHD is
outputted from HDMI OUT jack, DIGITAL
AUDIO OUT jack is limited to “PCM 2ch”
(When the HDMI and DIGITAL AUDIO OUT

The Dolby TrueHD audio recorded on some

through DIGITAL AUDIO OUT jacks and “DD
” displays on the screen if TrueHD audio is
not output (for example, when [HDMI] is set
to [PCM Stereo] and [Digital Output (SPDIF)]
is set to [Primary Pass-Thru]).

You must select a digital audio output
and a maximum sampling frequency that
your Amplifi er (or AV receiver) accepts
using [Digital Output (SPDIF)], [HDMI] and
[Sampling Freq.] options on the [Setup]
menu (see page 27-28).

[Digital Output (SPDIF)] or [HDMI] option is
set to [Primary Pass-Thru].

If the audio format of the digital output
does not match the capabilities of your
receiver, the receiver will produce a strong,
distorted sound or no sound at all.
