Dolby Headphone

This system incorporates Dolby Headphone
technology. Dolby Headphone allows you to
enjoy multichannel surround sound effects
with two-channel stereo headphones. Dolby
Headphone works with both multichannel
sources, such as Dolby Digital and DTS
DVDs, and stereo sources. Surround sound
from stereo sources is achieved using Dolby
Pro Logic II decoding.
About Dolby Headphone effects
Music and movie soundtracks through
headphones can sound rather unnatural.
This is because they are mixed and produced
to be listened to through speakers some
distance in front of you (or around you in the
case of multichannel sources).
Dolby Headphone recreates the sound of
speakers in a room, thereby making the
sound through headphones more natural for
the listener.
You can choose between three room types:
DH1: Mixing room with very little
reverberation.
DH2: Ordinary listening room with
moderate reverberation (default setting).
DH3: Small movie theater.

Dolby Pro Logic II

Dolby Pro Logic II is a decoding technology
for playing two-channel sources in 5.1
channel surround. Like Dolby Digital, the
main five channels are full bandwidth. Dolby
Pro Logic II decoding has minimal impact on
sound quality and creates a very natural
surround sound effect.
