!When this unit is connected to a power amp with input level control, auto TA and EQ may not be possible if you lower power amp input level. Set the power amp’s input level to the standard position.
!When this unit is connected to a power amp with an LPF, turn off the LPF on the power amp before carrying out auto TA and EQ. In addition, the
!The time alignment value calculated by auto TA and EQ may differ from the actual distance in the following circumstances. However, the distance has been calculated by computer to be the optimum delay to give accurate results for the circum- stances, so please continue to use this value.
—When the reflected sound within a vehi- cle is strong and delays occur.
—When delays occur for low sounds due to the influence of the LPF on active subwoofers or external amps.
!Auto TA and EQ changes the audio settings as below:
—The fader/balance settings return to the center position. (Refer to page 57.)
—The graphic equalizer curve switches to Flat. (Refer to page 65.)
—When a subwoofer is connected to this unit, it will be adjusted automatically to both subwoofer output and high pass fil- ter setting for rear speaker.
!If you carry out auto TA and EQ when a pre- vious setting of this already exists, the set- ting will be replaced.
!When connecting tweeters, please confirm the tweeter’s usable frequency range. When you set the
!Auto TA uses higher range than 10 kHz for measurement. Therefore, using the tweeter that cannot reproduce 10 kHz frequency
range may damage the tweeter. When Auto TA&EQ is operated, be sure to set the ap- propriate
Carrying out auto TA and EQ
1Stop 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 TA and EQ.
2Fix the supplied microphone in the cen- ter of the headrest of the driver’s seat, fa- cing forward, using the belt (sold separately).
#The auto TA and EQ may differ depending on where you place the microphone. If desired, place the microphone on the front passenger seat to carry out auto TA and EQ.
3Turn the ignition switch to ON or ACC.
# If the car’s air conditioner or heater is turned on, turn it off. Noise from the fan in the air condi- tioner or heater may prevent correct auto TA and
EQ.
# Press SOURCE to turn the source on if this unit is turned off.
