Multi channel surround setup
(continued)
Tip
The ]_ceiver alhlws you to inpul the speaker position
in terms of distance. However, it is not possible to set
die center speaker furdter than the front speakers.
Also, tile center speaker cannot be set more than
1.5 meters (5 fee0 closer than the front speakers.
Likewise, tile sttrround and surround back speakers
can not be set farther away from tile listening position
dlan the front speakers. And they cart be no more than
4.5 meters (15 feet) closer.
This is b_ause incorrect speaker placement is not
conducive to enjoy surround sound.
Please note that, setting the speaker distance closer
than the actual location of the speakers wil! cause a
delay in tile output of the sound from that speaker. In
other words, the speaker will sound like it is f_r tber
away.
For example, setting tile center speaker distance
I-2 m (3-6 feet) closer than the actual speaker
position will create a t3irly l_alistic sensation of being
"inside" the Selden. If you cannot obtain a satisfactory
SmTOUnd effect because the surround speakers are too
close, setting the surround speaker distance closer
(shorter) than the actual distance will creale a larger
sound stage.
Adjusting these parameter while listening to the
sound often results in much better surround sound.

• LFE high cut filter (LFE HIGH CUT •
XXX Hz)
Lets you select the cut off frequency of the
LFE ch_mnel high cut filler. Normally, select
"STD'. When using a passive sub woofer
powered by a separate power _unplifier, it may
be better to change the cut off frequency.
• Sub woofer phase polarity (S.W
PHASE)
Set the sub woofer phase polarity. There is
usually no problem when the sub woot?r ph_rse
polarity is set to "NORMAL". However,
depending on the type of front speakers, the
position of the sub woofer, and the cut-off
frequency of the sub woofer, setting the phase
pokwity to "REVERSE" may produce better
bass. Besides bass reproduction, the richness
_md tightness of tbe overNl sound may also be
_fffected. While listening from tbe main
listening position, select the setting that best
suits your environment.
