Positioning the loudspeakers
X
Carry out the following steps very accurately, since the more accurate the physical arrange-
ment of the loudspeakers in the room, the more accurate the reproduction will be at the
listening position .
X
Observe the recommended distances between the loudspeakers and your listening position:
• Recommended listening distance: 1 .0 m – 2 .5 m
• Min ./max . listening distance: 0 .75 m – 6 .0 m
X
Avoid positioning the loudspeaker at a distance (d
wall
) of 0 .8 to 1 .75 m from the wall behind
the loudspeaker . When positioning bass-managed loudspeakers, avoid a distance (d
wall
) of
0 .8 to 1 m from a solid wall behind the loudspeaker . Similarly, avoid these distances from
solid side walls or a solid ceiling . Respecting these positioning limitations reduces the
chances of dips in the low frequency response (comb filtering) caused by strong reflections .
X
Print out the “Installation angles” diagram that can be found at the end of this operating
manual .
X
Place the diagram at the listening position or the center of the listening area .
X
Using a tape measure, place the loudspeakers at the same distance from the center of the
diagram “Installation angles” . To ensure good imaging, do this at an accuracy of at least
1 cm .
X
If the loudspeakers cannot be placed at the same distance from the listening position, com-
pensate for distance differences > 1 cm by delaying closer loudspeakers by 30 µs/cm . The
MA 1 – Automatic Monitor Alignment
software automatically compensates for different dis-
tances between the loudspeakers and the listening position .
X
Arrange the loudspeakers as follows:
• 2 .0 systems (stereo): ± 30°, plus optional subwoofer(s)
• 5 .1 systems:
ITU-R BS .775-1:
0°, ±30°, ±110° (±10°), plus optional subwoofer(s)
(center, front left/right, surround left/right)
ANSI/SMPTE 202M:
0°, ± 22 .5°, one surround array left and right, plus optional
subwoofer(s)
• 7 .1 systems:
0°, ± 30°, ± 90°, ± 150°, plus optional subwoofer(s)
(center, front left/right, side left/right, back left/right)
• 3D systems
See the recommendations from Dolby, DTS, Auro3D and
ITU-R BS .2051-0 for loudspeaker positioning .
The acoustical axis of the loudspeaker is between the bass and tweeter drivers .
X
Always point the acoustical axis, in the horizontal and vertical planes, towards the listening
position .
The acoustical axis is a line perpendicular to the loudspeaker’s front panel along which
the microphone was placed to tune the loudspeaker’s crossover when the monitor was
designed . Pointing the acoustical axis, in the horizontal and vertical planes, toward
the listening position or center of the monitoring area will give the best measured and
perceived transient response quality .
X
Position the loudspeaker so that there is a direct line of sight from the listening position to
the bass and tweeter drivers .
X
Make sure that the ports are not blocked or partially covered .
X
Keep sharp edges away from the port outlets, as they can cause air noise .
