Speaker Setting Guide

In order to achieve an even better surround
effect, it is important to accurately position
the speakers and make their volume and tone
characteristics uniform so as to finely focus the
multi-channel sound.
The three major elements in positioning the
speakers are

distance

angle

and

orienta-

tion

(the direction in which the speakers are

pointing).

Distance

: The distance of all the speakers

should be equal.

Angle

: The speakers should be horizontally

symmetrical.

Orientation

: The orientation should be horizon-

tally symmetrical.
In most homes, however, it is not possible to
achieve this environment. For the distance, on
this receiver it is possible to automatically cor-
rect the speaker distance electrically to a preci-
sion of 0.5 inch using the Full Auto MCACC
Setup function (page 26).

: For the volume and sound quality

as well, accurate sound field correction using
the equalizer and speaker phase characteristic
correction using the Full Band Phase Control
function (page 39) together make it possible to
achieve the ideal listening environment.

Step 1: Speaker layout and

distance adjustment

Use speaker stands or the like to make sure the
speakers are steady, and leave at least 10 cm
(4 inches) from the surrounding walls. Position
the speakers attentively so that the speakers on
the left and right are at equal angles from the
listening position (center of the adjustments).
(We recommend using cords, etc., when adjust-
ing the layout.) Ideally all the speakers should
be equidistant from the listening position.

Note

If the speakers cannot be set at equal

distances (on a circle), use the Auto MCACC
Setup speaker distance correction and Fine
Speaker Distance functions to make them
equalize the distance artificially.

Step 2: Adjusting the speaker

height

Adjust the heights (angles) of the different
speakers.
Adjust so that the front speaker units reproduc-
ing mid- and high frequencies is roughly at the
height of the ears.
If the center speaker cannot be set at the same
height as the front speakers, adjust its angle of
elevation to point it to the listening position.
Set surround speaker 1 so that it is not under
the height of the ears.

Step 3: Adjusting the speaker

orientation

If the left and right speakers are not pointing
in the same direction, the tone will not be the
same on the right and left, and as a result the
sound field will not be reproduced properly.
However, if all the speakers are pointed towards
the listening position, the sound field will seem
cramped. Testing by the Pioneer Multi-channel
Research Group has shown that a good sense
of sound positioning can be achieved by point-
ing all the speakers towards an area 30 cm to 80
cm (12 inches to 31 inches) behind the listening
position (between the surround speakers and
the listening position).
However, the sense of sound positioning can
differ according to the conditions in the room
and the speakers being used. In smaller envi-
ronments in particular (when the front speakers
are close to the listening position), with this
method the speakers will be pointed too inward.
