Before operating the Auto EQ
function
●
Perform Auto EQ in as quiet a place as possible, with the
vehicle engine and air conditioning switched off. Also, cut
power to car phones or cellular phones in the vehicle, or
remove them in advance. Surrounding sounds may prevent
correct measurement of the vehicle’s acoustics.
● Be sure to use the microphone for acoustical measurement
(sold separately). Using another microphone may prevent
measurement, or result in incorrect measurement of the
vehicle’s acoustics.
● To perform Auto EQ, the front speakers must be connected.
●
When this product is connected to a power amp with input
level control, Auto EQ may be impossible if the power amp’s
input level is set below the standard level.
● When this product is connected to a power amp with an LPF
(low pass filter), turn the LPF off before performing Auto EQ.
Also, set the cut-off frequency for the built-in LPF of an active
subwoofer to the highest frequency.
● The distance has been calculated by a computer to provide
optimum delay to ensure accurate results. Do not change
this value.
— The reflected sound within the vehicle is strong and delays
occur.
— The LPF on active subwoofers or external amps delay the
lower sounds.
●
If an error occurs during measurement, check the following
before measuring the vehicle’s acoustics.
— Front speakers (left/right)
— Rear speakers (left/right)
— Noise
— Microphone for acoustical measurement (sold separately)
— Low battery
