Before operating the auto TA and EQ function

!Carry out auto TA and EQ in as quiet a place as possible, with the car engine and air conditioning switched off. Also cut power to car phones or portable telephones in the car, or remove them from the car be- fore carrying out auto TA and EQ. Sounds other than the measurement tone (sur- rounding sounds, engine sound, tele- phones ringing etc.) may prevent correct measurement of the car interior acoustic characteristics.

!Be sure to carry out auto TA and EQ using the supplied microphone. Using another microphone may prevent measurement, or result in incorrect measurement of the car interior acoustic characteristics.

!When front speaker is not connected, auto TA and EQ cannot be carried out.

!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 cut-off frequency for built-in LPF of an active subwoofer should be set to the highest frequency.

!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 72.)

—The equalizer curve switches to FLAT. (Refer to page 77.)

—It will be adjusted automatically to high pass filter setting for front, center and 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.

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 conditioner or heater may prevent correct auto

TA and EQ.
