Virtual CINEMA DSP

With Virtual CINEMA DSP, you can enjoy all DSP
programs without rear speakers. It creates virtual speakers
to reproduce a natural sound field.
You can listen to virtual CINEMA DSP by setting “1C
REAR LR” in the set menu to NON. Sound field
processing changes to VIRTUAL CINEMA DSP
automatically.

Note

• This unit is not set in the virtual CINEMA DSP mode even if

“1C REAR LR” is set to NON in the following cases:
– when the 6ch Stereo, DOLBY DIGITAL, Pro Logic, Pro

Logic II, or DTS program is selected;

– when the sound effect is turned off;
– when 6CH INPUT is selected as the input source;
– when a digital signal with a sampling frequency greater

than 48 kHz is input to this unit;

– when using the test tone; or
– when connecting the headphones.

■

SILENT CINEMA DSP

You can enjoy a powerful sound field similar to what you
could expect from actual speakers through headphones,
with SILENT CINEMA DSP. You can listen to SILENT
CINEMA DSP by connecting your headphones to the
PHONES jack while the digital sound field processor is
on. The “SILENT” indicator lights up on the front panel
display. (When sound effects are off, the unit reproduces
the source in normal stereo.)

Notes

• This feature is not available when 6CH INPUT is selected or

the unit is receiving a digital signal with a sampling frequency
greater than 48 kHz.

• The sound from the LFE channel will be mixed and output

from the headphones.
