Enjoying stereoscopic sound fields
(CINEMA DSP 3D)
CINEMA DSP 3D creates a natural stereoscopic sound field in your
room.
CINEMA DSP 3D functions when both of the following conditions
are met.
• One of the sound programs (except 2ch Stereo and 7ch Stereo) is
selected (p.48).
• "CINEMA DSP 3D Mode" (p.79) in the "Option" menu is set to
"On".
"CINEMA DSP -_" lights up
Enjoying unprocessed playback
You can play back input sources without any sound field effect
processing.
Playing back in original channels
(straight decode)
When the straight decode mode is enabled, the unit produces
stereo sound from the front speakers for 2-channel sources such as
CDs, and produces unprocessed multichannel sounds for
multichannel sources.
Press STRAIGHT.
Each time you press the key, the straight decode mode is
enabled or disabled.
• We recommend using presence speakers in order to experience the full effect of
the stereoscopic sound fields. However, even when no presence speakers are
connected, the unit creates Virtual Presence Speaker (VPS) using the front,
center, and surround speakers to produce stereoscopic sound fields.
Enjoying sound field effects without
surround speakers (Virtual CINEMA DSP)
If you select one of the sound programs (except 2ch Stereo and
7ch Stereo) when no surround speakers are connected, the unit
automatically creates the surround sound field using the front-side
speakers.
• To enable 6.1/7.I-channel playback from 5.1-channel sources when surround
back speakers are used, set "Extended Surround" (p.80) in the "Option" menu to a
setting other than "Off".
