SPEAKER PLACEMENT
The ideal surround speaker system for this unit is
7-speaker systems, using front left and right
speakers, a center speaker, surround left and right
speakers, a surround back left and right speakers,
and a subwoofer.
For best results we recommend that all front
speakers be of the same type, with identical or
similar driver units. This will deliver smooth pans
across the front sound stage as the action moves
from side to side.
Your center channel speaker is very important as
over 80 % of the dialog from a typical motion
picture emanates from the center channel.
It should possess similar sonic characteristics to
the main speakers. Surround channel speakers
need not be identical to the front channel speakers,
but they should be of high quality.
The surround center speaker is useful for playback
of Dolby Digital Surround EX or DTS-ES. One of
the benefits of both Dolby Digital and DTS is that
surround channels are discrete full range, while
they were frequency limited in earlier “Pro Logic”
type systems.
Bass effects are an important part of home theater.
For optimal enjoyment a subwoofer should be used
as it is optimized for low frequency reproduction. If
you have full range front speakers, however, they
may be used in place of a subwoofer with proper
setting of the switches in the menu system.
Front left and right speakers
We recommend to set the front L and R speakers
with 45-60 degrees from the listening position.
Center speaker
Align the front line of the center speaker with the
front L/R speakers. Or place the center speaker a
little backward from the line.
Surround left and right speakers
When the SR7500 is used in surround operation,
the preferred location for surround speakers is on
the side walls of the room, at or slightly behind the
listening position.
The center of the speaker should face into the
room.
Surround back left and right speakers
Surround back speakers are required when a full
7.1-channel system is installed.
Speakers should be placed on a rear wall, behind
the listening position.
The center of the speaker should face into the
room.
Subwoofer
We recommend using a sub-woofer to have maximum
bass effect. Sub-woofer bears only low frequency
range so you can place it any where in the room.
HEIGHT OF THE SPEAKER UNITS
Front left and right speakers, and a center speaker
Align the tweeters and mid-range drivers on the
three front speakers at the same height, as best as
possible.
Surround left and right speakers, and surround
back speaker
Place the surround left, right and surround back
speakers higher than your ears by about 70cm–
1m. Also place the speakers at the same height, sa
best as possible.
Note:
• Use magnetically-shielded speakers for front left,
right and the center speakers when the speakers
are installed near the TV and the TV is a monitor
type.
