reating the auto-equalizer curve
The auto-equalizer automatically measures the
car interior acoustic characteristics, and then
creates the auto-equalizer curve based on that
information.
WARNING:
• 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.
PRECAUTION:
• 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 output higher than the speak-
er’s maximum input power capability.
• 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.)
Before operating the auto-equalization
function
• 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.
• 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.
• Auto-equalizing changes the audio settings as
below:
– The fader/balance settings return to the cen-
ter position. (Refer to page 43.)
– The graphic equalizer curve switches to
“FLAT”. (Refer to page 48.)
– 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.
• If you carry out auto-equalizing when an auto-
equalizer curve already exists, the previous
curve will be erased.
Carrying out auto-equalizing
1. Stop the car in a place that is as quiet as
possible, close all doors, windows and
the sun roof, and then turn the engine off.
If the engine is left running, engine noise
may prevent correct auto-equalizing.
