DOLBY SETUP
Under this menu, the Dolby Digital’s Dynamic Range Control can be adjusted as well as the settings for
Dolby Digital Pro Logic IIx Music.
Dyn Range Ctrl :You can select the eective dynamic range (subjective range from soft to
loud) for playback of Dolby Digital soundtracks. For fully cinematic eect, always select 100%, the
default. Settings of 75%, 50%, and 25% progressively reduce dynamic range, making soft sounds
comparatively louder while limiting the peak loudness of loud ones.
The 25% setting will yield the least dynamic range and is best for late-night sessions or other times
when you wish to retain maximum dialog intelligibility while minimizing overall volume levels.

DTSHD MASTER AUDIO
DTS-HD Master Audio is a technology that delivers master audio sources recorded in a professional
studio to listeners without any loss of data, preserving audio quality. DTS-HD Master Audio adopts
variable data transfer rates, facilitating data transfer to the maximum rate of 24.5 Mbps in the Blu-ray
disc format, 18.0 Mbps in the HD-DVD format, which by far exceeds that of a standard DVD. These high
data transfer rates enable lossless transmission of 96 kHz/24-bit 7.1-channel audio sources without
deteriorating the quality of the original sound. DTS-HD Master Audio is an irreplaceable technology
that can reproduce sound faithfully as intended by the creator of music or movies.
DTS ES EXTENDED SURROUND ™ DTS ES
This is a new multi-channel digital format which greatly improves the 360° spatial sensation of the
Surround impression thanks to the greater space expansion of the surround signals, providing high
compatibility with the conventional DTS format.
In addition to the 5.1 channels, the expanded DTS-ES Surround also oers the back surround (also
sometimes called the “surround centre”) in reproduction, providing a total of 6.1 channels. The
expanded DTS-ES Surround includes two formats, with two dierent methods of surround signal
