Notes on Auto-equalization
To assure correct measurement,
perform auto-equalization in an as quiet
environment as possible and after
switching the car engine, air conditioner
and heater off. The measurement of the
acoustic property in the car
compartment is affected by noise from
the surroundings of the car, the engine,
air conditioner or heater.
Always use the provided microphone to
perform the auto-equalization. Other
microphones may not be capable of
performing
auto-equalization or
measuring the acoustic property in the
car compartment.
The auto-equalization cannot be
performed if the middle/bass speaker
units are not connected in PRO mode or
the front speakers are not connected in
STD mode.
The auto-equalization is not carriad out
if fine-tuning of the position (fader/
balance) (P.32) is extremely set. Do not
adjust the fine tuning of the position
extremely.
When a power amp which has RCA
input level controls, be sure to set the
RCA input level controls to the 12
o'clock position.
If the level controls are
set at low position, auto-equalizing can
not be carried out correctly.
The results of the auto-equalizing
depend on the settings of the network
adjustment (P. 18). Be sure to adjust the
network before performing auto-
equalizing procedures.
(If correct auto-
equalizing result cannot be obtained,
adjust the network again.)
Only one auto-equalizer curve can be
created. In case auto-equalization is
performed while there has already been
an auto-equalizer curve, the previously
created auto-equalizer curve will be
cleared from memory.
When auto-agualization ic carriad out.
the currently set equalizer curve (the
curve created by yourself (P. 29)) is
reset and made flat. If you want to keep
the current equalizer curve, store it in
the memory of this unit before
performing auto-equalization.
(Refer to "Storing Equalizer Curves" on
page 30.)
When auto-equalization is performed,
the following network adjustment items
adjusted by the user (P. 18) are altered.
—
Level of each speaker unit.
—
Phase of the sub-woofer.
—
Cutoff frequency and slope of rear-
speaker HPF "R" in STD mode (only
when the front, rear and subwoofer
are connected).
When the auto-equalization is carried
out, the all setting of the fine-tuning of
the position (fader/balance) (P. 32) are
initialized.
