yy The audio is outputted as PCM 48 kHz/16 bit for MP3/WMA file and PCM 44.1kHz/16 bit for Audio CD while playback.

yy The Dolby TrueHD audio recorded on some Blu- ray discs consists of Dolby Digital and TrueHD audio. Dolby Digital audio is output 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]).

yy 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).

yy 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].

yy 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.

yy Multi-channel Digital Surround Sound via digital connection can only be obtained if your receiver is equipped with a Digital Multi-channel decoder.
