Auto-Equalizing Function; Before Operating The Auto-Equalization - Pioneer DEH-P9100R Manual

Auto-equalizing Function

This product's Auto-equalizer automatically measures car interior acoustic characteristics, and
then creates the Auto-equalizer curve based on that information.

Before Operating the Auto-equalization

WARNING:
• To prevent accidents, never perform Auto-equalizing when driving. When this function measures car
interior acoustic characteristics to create an Auto-equalizer curve, a loud measurement tone (noise)
may be output from the speakers.
Precaution:
• Performing Auto-equalizing under the following conditions may damage the speakers. Be sure to
check conditions thoroughly before performing 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 speaker'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 location. (Refer to page 69.)
Read this before performing Auto-equalizing
• Perform Auto-equalizing in as quiet a place as possible, with the car engine and air conditioning
switched off. Also cut power to car or portable telephones in the car, or remove from the car before
performing Auto-equalizing. Sounds other than the measurement tone (surrounding sounds, engine
sound, telephones ringing etc.) may prevent correct measurement of car interior acoustic
characteristics.
• Be sure to perform Auto-equalizing with the supplied microphone. Using another microphone will
prevent measurement, or result in incorrect measurement of car interior acoustic characteristics.
• With no front or rear speaker connected, Auto-equalizing cannot be performed.
• When 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.
• After normal completion of Auto-equalizing, fader/balance settings (refer to page 56) return to the
center position (initial settings).
• If you perform Auto-equalizing when Auto-equalizer curve already exists, the previous curve is
erased.
• If you change the rear speaker output setting or the Subwoofer output setting after you performed
Auto-equalizing, Auto-equalizer curve is erased. In this case, perform Auto-equalizing again.
• If you perform Auto-equalizing, the equalizer curve switches to flat.
• If you perform Auto-equalizing while a Subwoofer is connected to this product, it will be adjusted
automatically either Subwoofer output and High Pass Filter output settings or Non-Fading output
level setting. (Subwoofer output or Non-Fading output is automatically turned on and adjusted even
if you have turned it off before.)
• After the Auto-equalizing function countdown has started, if you switch a source ON by loading a
CD or with the voice controller, source Audio Menu 1 settings change. Do not switch a source ON
after Auto-equalizing has begun.
