The microphone should be positioned as far out from the stand as possible to 
minimize the effect of stand reflections. 

NOTE:  You must place the microphone in a vertical position with the capsule 
facing the ceiling for all measurements. Refer to illustration on page 3. 

Quiet the room as much as possible. Background noise can disrupt the room 
measurements. Turn off cell phones, televisions, radios, air conditioners, fluorescent 
lights and other devices or home appliances. Close any open windows. 

Refrain from talking and do not sit or stand directly between any of the speakers and 
the microphone during the room measurements. Each speaker will emit a series of 
test signals during the measurements and your body and background noise can 
disrupt the microphone’s ability to properly record the room response to the test 
signal. 

For the Position 1 measurement, place the microphone at the primary or most central 
listening location. The height should be the ear height of a listener seated at this 
position.  

NOTE:  It is important to have the microphone in the primary listening position for 
the first measurement. Every position measurement will record the room’s frequency 
and time response but Position 1 also detects the absolute polarity of each speaker, 
calculates the exact distance (within a half inch) for setting delays and determines 
levels (within half a dB) for each speaker. The polarity, distance and level from the 
Position 1 measurement are displayed later on the Detection Results screen (refer to 
“Detection Results” on page 9). 

Press the Measure button. The Audyssey test signal will play a series of 10 “chirps” 
through each channel. The name of the speaker being measured will be indicated 
under the status bar while the test signal plays.
