Before Setting MultEQ
WARNING
While driving, do not set up MultEQ.
To prevent accidents, do not set up MultEQ while driving. The setting of the MultEQ
function is required to mount the microphone in the vehicle in order to measure sound
characteristics. Also, during measurement, loud measurement tone (signal) from the
speakers may be output. Making such settings may distract you from driving and result in
an accident.
Read following provisions before setting MultEQ.
• The MultEQ setting should be made in as quiet a place as possible after turning off the engine, air-
conditioner and heater. If you have a car phone or cellular phone in the vehicle, remove them from the
vehicle or turn its power off. If sound other than measurement tone to be measured (engine or receiving
sound of car phone, etc.) occur, sound measurement in the vehicle may not be accurate.
• When setting MultEQ, be sure to use the microphone supplied with this unit. If a microphone other than
the supplied one is used, measurement may not be possible or sound measurement in the vehicle may not
be accurate.
• If a power amplifier or a powered subwoofer with an input level control is connected and this level is
lowered, measurement may not be possible. However, the input level should set lowered than normal
level to adequately perform measurement.
• If a power amplifier with a low-pass filter is connected, measure MultEQ when the low-pass filter of the
power amplifier is turned off. If a low-pass filter is built into the powered subwoofer or power amplifier
for subwoofer, set the cut-off frequency to the highest value.
• If MultEQ is set and the function is turned on, MX, X-OVER, Time Correction, User's EQ, Parametric
EQ and Graphic EQ are automatically adjusted. Therefore, they cannot be individually adjusted.
• After you have stored the result of MultEQ you adjusted in the CDA-9887/CDA-9887R, if you store the
results of MultEQ again in the CDA-9887/CDA-9887R, the previously stored MultEQ will be
completely cleared and replaced by the new one.
