Delay time ( b)
[DVD-V] (Dolby Digital, center and surround speakers only)
For optimum listening with 5.1-channel sound, all the speakers, except for
the subwoofer, should be the same distance from the seating position. If you
have to place the center or surround speakers closer to the seating position,
adjust the delay time to make up for the difference.
If distance
d (from the center speaker) and f (from the surround speak-
ers) are the same as or greater than e (from the front speakers), leave the
delay time as “0”, the factory preset.
If either distance
d or f is less than e, find the difference in the relevant
table and change to the recommended setting.
Changing the delay time
1. Use [3, 4, 2, 1] to select the delay time box and press [ENTER].
2. Move [3, 4] to adjust the delay time and press [ENTER].

2. While listening to the test signal, move [3, 4] to adjust the vol-
ume of the center and surround speakers so they are the same
apparent volume as the front speakers.
(The front speakers cannot be adjusted here.)
3. Press [ENTER].
The test signal stops.
Note
No signal is output for the subwoofer. To adjust its volume, play something,
then return to this screen to adjust to suit your taste.
When you are finished
Use [3, 4, 2, 1] to select “Exit” and press [ENTER].
Note
The unit may be unable to output as set here due to limitations imposed by
the unit itself or the disc being played. (The FL display’s “P.PCM” indicator
lights or “D.MIX” indicator goes out in these cases.)

PCM Down Conversion
Select how to output the high-quality audio signals (sampling frequencies
of 96 kHz and 88.2 kHz) on discs that do not have copyright protection.
Choose the settings to suit the equipment you have connected.
Note
≥ Some equipment cannot handle sampling frequencies of 88.2 kHz, even
if they can handle 96 kHz. Read your equipment’s operating instructions
for details.
≥ Signals are down-sampled to either 48 kHz or 44.1 kHz despite the
above settings if they have a sampling frequency of 176.4 kHz or more or
are copyright protected.
Dolby Digital, DTS Digital Surround and MPEG §
Bitstream: Select if the equipment you connected can decode the signal.
(Factory preset for Dolby Digital)

(Factory preset for DTS Digital Surround and MPEG)
IMPORTANT
If the equipment you connected cannot decode the signal, the setting
must be changed to PCM. If not, signals the equipment cannot pro-
cess will be output by this unit, causing high levels of noise which
can damage your hearing and the speakers.
