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.

Carrying out auto TA and EQ

 

1 Stop the car in a place that is as quiet

 

the sun roof, and then turn the engine off.

 

If the engine is left running, engine noise may

 

prevent correct auto TA and EQ.

 

2 Fix 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.
