• Sub woofer selecuon .W.
• If you connect a sub wool?r, select "YES'.
• If you do not connect a sub woofer, select
"NO". This activates the bass redirection
circuitry and outputs the LFE signals from other
speakers.
• In order to take full advantage of the Dolby
Digital bass redirection circuitry, we
recommend setting the sub woof_r's cut off
frequency as high as possible.
• Front speaker distance (_ _ DIST.
XX.X m)
Set the distance from your listening position to
the front speakers (O on page 15).
• Center speaker distance (_ DIST.
XX.X m)
Set the distance l¥orn your listening position to
the center speaker. Center speaker dist*mce
should be set from a distance equal to the front
speaker distance (O on page 15) to a dist_mce
1.5 meters closer to your listening position (_
on page 15).
• Surround speaker d,stsnce (_
DIST. XX.X m)
Set the distance from your listening position to
the surround speakers. Surround speaker
distance should be set l?om a distance equal to
the front speaker distance (_ on page 15) to a
dist_mce 4.5 meters closer to your listening
position (_ on page 15).
Tip
The ]_ceiver allows you to input _he speaker position
in terms of distance. However, it is not possible to set
the center speaker furdler than the front speakers.
Also, the center speaker cannot be set more than
1.5 meters closer than the front speakers,
Likewise, tile st_rround speakers can not be set farther
away from tile listening lx)sition than the front
speakel\a. And they can be no more than 4.5 meters
closer.
This is b_ause incorrect speaker placemenl is not
conducive to enjoy surround sound.
Please note that, setting tile speaker distance closer
than the actual location of the speakers will cause a
delay in the output of the sound from that speaker. In
other words, the speaker will sound like it is farther
away.
For example, setting the center speaker distance
1_2 m closer than the actual speaker position will
create a fairly l_alistic sensation of being "inside" the
screen. If you cannot obtain a satisfactory surround
effect because tile surround speakers are too close,
setting tile stlrround speaker distance closer (shorter)
than lhe actual distance will create a larger sound
s_age.
Adjusting these parameter while listening to tile
sound often results in much better surround sound.
Give it a try!
