EQ-6000
@ Dual Amp Balancer
Allows adjustment of the balance between the front and rear speakers.
Moving upwards causes rear speaker output to be reduced until only the
front speaker sounds. Moving downwards causes front speaker output
to be reduced until only the rear speaker sounds.
@ Parametric Frequency Control
Use this control to change heavy bass frequency when operating the para-
metric equalizer. The control allows to choose your desired frequency from
between 40 Hz and 80 Hz according to the type of speakers and the
piece of music listened to.
© Parametric Level Control
Use this control to adjust the level of the heavy bass frequency sound
chosen with the Parametric Frequency Control @.
@ Equalizer Control
Sliding vertically allows creation of a desired sound.

© Equalization Switch
Press to activate the equalizer control function and illuminate the indica-
tor on the equalizer control lever.
@ Hlumination Color Change
To change illumination color, press the button Illumination Color Change.
Pressing allows change from green to amber and vice versa.
¢ If your car stereo has a fader control, set it to the center position.
© Changes in low pitched sounds may not be discernible even when the
60 Hz frequency level is adjusted if the program source does not in-
clude components in the 60 Hz vicinity or if the small diameter speakers
are used.
* Changes in high pitched sounds may not be discernible even when
the 16 kHz frequency level is adjusted if the program source does not
include components in the 16 kHz vicinity.

@ Equalization Switch
Press this button, and @, ©, and @ lever indicators will illuminate and
the equalizer control function will activate.
© Crossover Frequency Switch
Allows to change the upper limit of crossover low range frequency for
subwoofer speakers or the lower limit of crossover mid to high range fre-
quency for other speakers. Select the best crossover frequency while
listening to music according to the acoustic characteristics of both cabin
and speakers, Set the switch at the ‘‘OFF’’ position when not using the
subwoofer system.
@ Subwoofer Level Control
Allows adjustment of the output level of the subwoofer speaker. Use this
control to adjust the low range of the output.
@ Illumination Color Change
To change illumination color, press the button Illumination Color Change.
Pressing allows change from green to amber and vice versa.
© Subwoofer Phase Switch
Allows switching of the phase of the subwoofer speaker. Usually this
switch is left in the NOR (normal) position. Set to the REV (reverse phase)
position to switch the phase to accommodate for speaker position and
music type.
¢ Controls @, @ and @ operate when the subwoofer system is con-
nected.
¢ !f your car stereo has a fader control, set it to the center position.
¢ Changes in low pitched sounds may not be discernible even when the
40 to 80 Hz frequency level is adjusted if the program source does
not include components in the 40 to 80 Hz vicinity or if the small di-
ameter speakers are used.
¢ Changes in high pitched sounds may not be discernible even when
the 16 kHz frequency level is adjusted if the program source does not
include components in the 16 kHz vicinity.
