Denon AVR-1803 Operating Instructions Manual page 59

Here we describe a number of speaker settings for different purposes. Use these examples as guides to set up your system according to the type
of speakers used and the main usage purpose.
1. DTS-ES compatible system (using surround back speakers)
(1) Basic setting for primarily watching movies
Surround back speakers
(1 spkr or 2 spkrsl
As seen from above
l
Set the front speakers wrth therr front surfaces as flush with the TV
or monitor screen as possrble. Set the center speaker between the
Surround speaker
front left and right speakers and no further from the listening position
than the front speakers.
Pornt slightly

l
Consult the owner's manual for your subwoofer for advtce on placing
the subwoofer withrn the hstenrng room.
l
If the surround speakers are direct-radiating (monopolar) then place
them slrghtly behind and at an angle to the lrstenrng position and
parallel to the walls at a posrtron 60 to 90 centrmeters (2 to 3 feet)
above ear level at the prime lrstenrng posrtion.

l
When using two surround back speakers, place them at the back
facing the front at a narrower drstance than the front left and right speakers. When using one surround back speaker,
place It at the rear center facing the front at a sirghtly higher position (0 to 20 cm) than the surround speakers.
l
We recommend installrng the surround back speaker(s) at a slrghtly downward facing angle. This effectively prevents
the surround back channel srgnals from reflectrng off the monitor or screen at the front center, resulting in interference
and making the sense of movement from the front to the back less sharp.
(2) Setting for primarily watching movies using diffusion type speakers for the surround speakers
For the greatest sense of surround sound envelopment, diffuse radiation speakers such as bipolar types, or dipolar types, provide a wider
dispersion than is possible to obtain from a direct radiating speaker (monopolar). Place these speakers at either side of the prime listening
position, mounted above ear level.

speakers to the listening position
l
Set the front speakers, center speaker and subwoofer rn the same
positrons as rn example (Ii. Surround speaker Surround back I
l
It IS best to place the surround speakers drrectly at the side or slightly
to the front of the vrewing posrtron, and 60 to 90 cm above the ears.
l
Same as surround back speaker installatron method (I).
Usrng drpolar speakers for the surround back speakers as well is
more effective.
l
Connect the surround speakers to the surround speaker jacks.
l
The srgnals from the surround channels reflect off the walls as
shown on the dragram at the left, creating an enveloping and realrstrc
surround sound presentatron.

For multi-channel musrc sources however, the use of bipolar or dipolar
speakers mounted at the sides of the listening position may not be satisfactory in order to create a coherent 360 degree
surround sound field. Connect another pair of direct radiating speakers as descrrbed rn example (3) and place them at
the rear corners of the room facing towards the prime listening position.
2. When not using surround back speakers

l
Set the front speakers wrth thetr front surfaces as flush wrth the TV or
monrtor screen as possrble. Set the center speaker between the front left
and right speakers and no further from the Irstenrng posrtion than the front
speakers.
l
Consult the owner's manual for your subwoofer for advrce on placing the
subwoofer within the lrstenrng room.
l
If the surround speakers are drrect-radrating (monopolar) then place them
slightly behrnd and at an angle to the lrstenrng posrtron and parallel to the
walls at a posrtion 60 to 90 centimeters (2 to 3 feet) above ear level at the
prime listening posrtion.
