MP3/WMA file and PCM 44.1kHz/16 bit for Audio
CD while playback.
y The Dolby TrueHD audio recorded on some Blu-
ray discs consists of Dolby Digital and TrueHD

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]).
y You must select a digital audio output and
a maximum sampling frequency that your
Amplifier (or AV receiver) accepts using [Digital
Output (SPDIF)], [HDMI] and [Sampling Freq.]
options on the [Setup] menu (see page27).
y With digital audio connection (DIGITAL AUDIO
OUT or HDMI), Disc Menu button sounds of BD-
ROM may not be heard if the [Digital Output
(SPDIF)] or [HDMI] option is set to [Primary Pass-
Thru].
y 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.
y Multi-channel Digital Surround Sound via digital
connection can only be obtained if your receiver
is equipped with a Digital Multi-channel decoder.
