Auto-Equalizing Function; Before Operating The Auto-Equalization - Pioneer MEH-P9100R Operation 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

7 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.
7 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 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 location. (Refer to page 57.)
7 Read this before performing Auto-equalizing
• Perform Auto-equalizing in as quiet a place as possible, with the car engine and air con-
ditioning 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 measure-
ment tone (surrounding sounds, engine sound, telephones ringing, etc.) may prevent cor-
rect measurement of car interior acoustic characteristics.
• Be sure to perform Auto-equalizing with the supplied microphone. Using another micro-
phone 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.
