Special features
3
Large FL display, 14-band equalizer
and 27-spectrum analyzer
The large FL display, 14-band equalizer and 27-spectrum analyzer features
high visibility of information and make it possible to set EQ (equalizer) curves
with high accuracy.
MANUAL/REFERENCE modes
PARAMETRIC/GRAPHIC modes
MANUAL:
Five preset patterns have been factory-preset for this mode, too. In
this mode, it is also possible to preset (assign) equalizer patterns
created by the user in place of the factory presets.
@
REFERENCE:
Five exemplary patterns have been preset at the factory. #
PARAMETRIC: Equalizer curves can be created by setting up to 3 center
frequencies and the equalizing levels for them.
%
GRAPHIC:
The equalizer curve can be adjusted in a detailed way for every
frequency range. It is also possible to fine-adjust a curve which
has been created in the PARAMETRIC mode. The GRAPHIC
mode is to be used when detailed adjustment of acoustic
compensation is required.
&
GENRE mode
A total of 30 playback patterns have been factory-preset by combining five
recommended equalizer patterns with six music genres, so that any of them
can be selected by actually comparing them. Similarly, selection from 30
types of recording patterns for playback on car stereo or from 30 types of
recording patterns for playback on headphone stereo is also available. Select
the optimum equalizer pattern according to the music genre and purpose of
use of the pattern.

IMPORTANT SAFEGUARDS
G-EQ300 (En/K)
3Caution : Read this page carefully to ensure safe operation.
13.Lightning – For added protection for this appliance during a
lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and
disconnect the antenna or cable system. This will prevent
damage to the appliance due to lightning and power-line
surges.
18.Power lines – An outside antenna system should not be
located in the vicinity of overhead power lines or other electric
lightorpowercircuits, orwhereitcanfallintosuchpowerlines
orcircuits.Wheninstallinganoutsideantennasystem,extreme
care should be taken to keep from touching such power lines
or circuits as contact with them might be fatal.
5
14.Abnormal smell – If an abnormal smell or smoke is
detected, immediately turn the power OFF and unplug
the appliance from the wall outlet. Contact your dealer or
nearest service center.
19.AC outlets – Do not connect other audio equipment
with a power consumption larger than that specified to
the AC outlet on the rear panel. Never connect other
electrical appliances, such as an iron or toaster, to it to
prevent fire or electric shock.
POWER OFF!
15.Damage requiring service – The appliance should be
serviced by qualified service personnel when:
A. The power-supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the
appliance.
20. Overloading – Do not overload wall outlets, extension cords,
or integral convenience receptacles as this can result in a risk
of fire or electric shock.
C. The appliance has been exposed to rain or water.
D. The appliance does not appear to operate normally by
following the instruction manual. Adjust only those controls
that are covered by the instruction manual as an improper
adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the appliance to its normal operation.
21. Attachment – Do not use attachments not recommended by
the appliance manufacturer as they may cause hazards.
22. Replacement parts – When replacement parts are required,

manual. All other servicing should be referred to qualified
service personnel.
17.Outdoor antenna grounding – If an outside antenna is
connected to the appliance, be sure the antenna system
is grounded so as to provide some protection against
voltage surges and built up static charges. Article 810 of
the National Electrical Code ANSI/NFPA 70, provides
information with respect to proper grounding of the
mast and supporting structure, grounding of the lead-in
wire to an antenna discharge unit, size of grounding
conductors, location of antenna discharge unit,
connection to grounding electrodes, and requirements
for the grounding electrode. See Figure.

Safety precautions
Beware of condensation
Whenwatervaporcomesintocontactwiththesurfaceofcoldmaterial,
water drops are produced.
If condensation occurs, correct operation may not be possible, or the
unit may not function correctly.
This is not a malfunction, however, the unit should be dried.
(To do this, turn the ON/STANDBY switch ON and leave the unit as it
is for several hours.)
Be especially careful in the following conditions:
¶When the unit is brought from a cold place to a warm place, and there
is a large temperature difference.
¶When a heater starts operating.
¶When the unit is brought from an air-conditioned place to a place of
high temperature with high humidity.
¶When there is a large difference between the internal temperature of
the unit and the ambient temperature, or in conditions where conden-
sation occurs easily.

Functions of graphic equalizer
Book shelf
Curtain
Compensation for the audio
characteristics of the listening room
The listening room may contain several objects. Some
of them reflect sound and some absorb sound , thus
the sound reaching your ears is considerably affected
Speaker
by these objects.
In such cases, the graphic equalizer can be used to
adjust the frequency response of the room for a flat
response from low to high frequencies.
¶Low frequencies are absorbed by beds, chairs, etc.
¶High frequencies are absorbed by curtains, screens,
etc.
¶The room structure can cause the low frequencies to
beunclear, orthesoundleveltoincreaseordecrease
depending on the frequency.
Carpet
Adjustment of sound to your individual taste
When the reproduced sound contains several musical
instruments and voices, the graphic equalizer allows
you to enhance or attenuate the sound of specific
instruments or voices.

Bass

Original, or ideal, speaker sound
Actual sound reaching the listener
Sound equalization
Super bass range (40 Hz ~ 63 Hz)
When this control is moved up, the bass instrument (double bass, bass
drums, or pipe organ, etc.) sound is increased.
Mid-high range (1.5 kHz ~ 2.5 kHz)
This range is related to stimulus and metallic sound. When this range
is well compensated, vivid sound can be obtained.
When the super bass sound is boomy, move this control down.
High range (3.9 kHz ~ 6.3 kHz)
Bass range (98 Hz ~ 160 Hz)
Usually, the listening room resonance frequency is in this range.
To eliminate bass resonance, move this control down.
Thisfrequencyrangeisrelatedtothehardnessofthesound. Whenthis
control is moved up, strings or brass instruments, such as flutes or
piccolos, are emphasized. When the control is moved down, the sound
will be more soothing.
Mid-bass range (250 Hz ~ 400 Hz)
Super high range (10 kHz ~ 16 kHz)
This range is the basis of music. Whether the sound is rich or not,
depends on this range. When the playback sound is not so good, move
this control up.
This frequency range is related to the details of the music. When this
control is moved up, super high frequency instruments, such as
triangles or cymbals, are emphasized, resulting in wide sound and
echoes.
Mid range (625 Hz ~1 kHz)
When this control is moved up or down, the baritone or soprano voice
is emphasized/de-emphasized. This range is related to the “presence”
of music.
