The auto-equalizer automatically measures the
car interior acoustic characteristics, and then
creates the auto-equalizer curve based on that
information.
0 To prevent accidents. never carry out auto-
equalizing while driving. When this function
measures
the
car interior acoustic characteris-
tics to create an auto-equalizer curve, a loud
measurement tone (noise) may be output
from the speakers.
0 Carrying out auto-equalizing under the follow-
ing conditions may damage the speakers. Be
sure to check the conditions thoroughly before
carrying out auto-equalizing.
-.When speakers are incorrectly connected.
(e.g., When a rear speaker is connected to a
subwoofer output.)
-When a speaker is connected to a power
amp delivering outpul higher than the speak-
er's maximum input power capability.
0 If the microphone is placed in an unsuitable
position the measurement tone may become
loud and measurement may take a long time,
resulting in a drain on battery power. Be sure
to place the microphone in the specified loca-
tion. (Refer to "Carrying out auto-equalizing".)
s Carry out auto-equalizing in as quiet a place
as possible, with the car engine and air condi-
tioning switched off. Also cut power to car
phones or portable telephones in the car, or
remove them from the car before carrying out
auto-equalizing. Sounds other than the mea-
surement tone (surrounding sounds engine
sound, telephones ringing etc.) may prevent
correct measurement of the car interior
acoustic characteristics.
* Be sure to carry out auto-equalizing using the
supplied microphone. Using another micro-
phone may prevent measurement, or result in
incorrect measurement of the car interior
acoustic characteristics.
0 When neither front nor rear speaker is con-
nected, auto-equalizing cannot be carried out.
* When this product is connected to a power
amp with input level control, auto-equalizing
may not be possible if you lower power amp
input level. Set the power amp's input level to
the standard position.
0 AIrto-equalizing changes the audio settings as
below:
-The fader/balance settings return to the cen-
ter position. (Refer to page 41.)
-The graphic equalizer curve switches to
"FLAT". (Refer to page 4.6.)
-When a subwoofer is connected to this prod-
uct, it will be adjusted automatically to either
subwoofer output and high pass filter setting
for rear speaker.
s If you carry out auto-equalizing when an auto-
equalizer curve already exists, the previous
curve will be
erased.
that is as quiet as
If the engine is left running, engine noise
may prevent correct auto-equalizing.
