Before Calibrating MullEQ
I ~ WARNING
While driving, do not set up MuItEQ.
NEVER try to calibrate MultEQ while driving. Road noise and vibration prevents any
measurement from being anywhere close to accurate. Mic placement and the measurement
test tone are critical to the accurate calibration
of MultEQ. The slightest movement while
driving and passengers sitting in the
car (including the driver) all contribute to poor
acoustical characterization. While all this is going on, the possibility
of being distracted and
causing an accident, is too obvious to even mention.
Don't do it!
Read following provisions before calibrating MuItEQ.
• Calibrate MultEQ in a setting with no background noises (or, at least very little). Turn off the engine, air-
conditioner, heater and anything else that could make noises during testing. For example, a phone (any
type as long as it can make noises to attract your attention) or dog (any breed for the same reason)
shouldn't be left in or around the vehicle. Any extraneous noises prevent accurate characterization of the
vehicle.
• Use only the microphone supplied with this unit for calibration.
It has been specifically selected for
optimum performance during the calibration procedure.
•
If amplifiers are being used to drive any of the speakers in the system, make sure the gains are set at
optimum levels for normal listening. Additional adjustments may be required
if initial calibration is not
satisfactory.
•
If an amplifier is being used to drive satellites in a 2-way system (satellite/subwoofer), the high-pass
filter used for the satellite amplifier must be turned
off before running MultEQ calibration. If a low-pass
filter is built into a powered subwoofer
or subwoofer amplifier, turn it off (if possible) or set the cut-off
frequency to the highest possible value.
•
Once MultEQ calibration is completed, MX, X-OVER, Time Correction, User's EQ, Parametric EQ and
Graphic
EQ are adjusted according to MultEQ's parameters. While MultEQ is on, they cannot be
adjusted independently.
• Storing the MultEQ settings in the
PXA-H I 00 erases any data previously saved from earlier calibrations.
MultEQ Calibration
1 Preparing for calibration
• Park the vehicle in a quiet location,
• Close doors, windows, sunroof, etc,
•
Turn off the engine of the vehicle.
• Set the air-conditioner and heater to
OFF.
2 Turn ignition switch of the vehicle to ACC (on).
