Audyssey Setup
8. Do not adjust Volume during the measurements as this
will cancel the measurements.
9. Do not hold the setup microphone in your hand during
measurements.
10. Avoid placing the setup microphone close to a seat back
or wall as sound reflections may give inaccurate results.
Measurements will be performed by placing the setup
microphone successively at multiple positions through -
out the entire listening area. For best results, we recom -
mend you measure in
six or more positions, as
shown in the illustration
(up to eight positions)
about the main listening
position (*M). Refer to
figure 18A.
The main listening
position is the position
where listeners would
normally sit or where
one would normally
sit alone within the
listening environment.
The ideal Loudspeaker
Placement in a room for the best sonic effect is in the
Side View Illustration. Refer to figure 18B. Both the
Front Height and Rear Height Loudspeakers should
be pointed slightly downward. Before starting Audys -
sey Setup, place the setup microphone in the main
listening position. Audyssey MultEQ
®
XT32 uses the
measurements from this position to calculate speaker
distance, level, polarity, and the optimum crossover
value.
The acoustic characteristics of the connected speak -
ers and listening room are measured and the optimum
settings are made automatically.
Assemble the supplied setup microphone and stand,
then place it in the main listen-
ing position. Refer to figure 17.
Keep the following things in
mind during the Audyssey pro -
cedure:
1. When placing the setup micro -
phone, adjust the height of the
sound receptor to the level of
the listener’s ear.
2. When performing Audyssey
Setup, MultEQ

functions
become active.
3. Make the room as quiet as
possible. Background noise
can disrupt the room measurements. Close windows,
silence cell phones, televisions, radios, air condition -
ers, fluorescent lights, home appliances, light dimmers,
or other devices as measurements may be affected by
these sounds.
4. Cell phones should be placed away from all audio
electronics during the measurement process as Radio
Frequency Interference (RFI) may cause measurement
disruptions (even if the cell phone is not in use).
5. Do not unplug the setup microphone from the main unit
until Audyssey Setup is completed.
6. Do not stand between the speakers and setup micro -
phone or allow obstacles in the path while the mea -
surements are being made. This will cause inaccurate
readings.
7. Loud test sounds may be played during Audyssey
setup. This is part of normal operation. If there is
background noise in the room, these test signals will
increase in volume.
When using a Powered Subwoofer(s) adjust the
controls on the Subwoofer for neutral settings, as
Audyssey will be making the adjustments of volume,
crossover frequency, etc. Refer to the Subwoofer Own -
ers Manual for additional information.
