Dolby Virtual Speaker mode
• The Dolby Virtual Speaker mode is a mode using 3D sound technology from Dolby Laboratories to achieve
multi-channel surround sound using only two speakers for the front channels.
• With two speakers for the front channels, one of two modes can be selected: Reference or Wide.
• The Dolby Virtual Speaker mode can be used not only with Dolby Digital and DTS multi-channel sources but
also with 2-channel sources. With 2-channel sources, one of two 2-channel modes can be selected: Virtual 1
(Dolby Pro Logic
II
Cinema) and Virtual 2 (Dolby Pro Logic).
• With a multi-channel speaker configuration (for example 5.1 channels), the Dolby Virtual Speaker mode
provides different effects according to the speaker configuration.

DOLBY VS (Dolby Virtual Speaker mode):
• REF (Reference mode)
This is the standard mode.
• WIDE (Wide mode)
This mode expands the front channel sound field.
D.COMP. (Dynamic range compression):
• This parameter adjusts the dynamic range of the
Dolby Digital sound. When listening with the
volume turned relatively low, at night for
example, set this to the “HI” side to lower the
peak of the sound and amplify the quieter
sounds, narrowing the dynamic range and
making the sound easier to listen to. Set to
“OFF” to turn this function off.
LFE (Low Frequency Effect):
• Program source and adjustment range
1. Dolby Digital : –10 dB to 0 dB
2. DTS Surround : –10 dB to 0 dB
• When Dolby Digital encoded software is played,
it is recommended that the LFE LEVEL be set to
0 dB for correct Dolby Digital playback.
• When DTS encoded movie software is played, it
is recommended that the LFE LEVEL be set to 0
dB for correct DTS playback.
• When DTS encoded music software is played, it
is recommended that the LFE LEVEL be set to
–10 dB for correct DTS playback.
