Be sure to read the instructions in this section carefully before use.
Make sure to observe the instructions in this manual as the conventions of safety symbols and messages
regarded as very important precautions are included.
We also recommend you keep this instruction manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
When Installing the Unit
Do not expose the unit to rain or an environment
where it may be splashed by water or other liquids,
as doing so may result in fire or electric shock.
Use the unit only with the voltage specified on the
unit. Using a voltage higher than that which is
specified may result in fire or electric shock.
Do not cut, kink, otherwise damage nor modify the
power supply cord. In addition, avoid using the
power cord in close proximity to heaters, and never
place heavy objects -- including the unit itself -- on
the power cord, as doing so may result in fire or
electric shock.
Be sure to replace the unit's terminal cover after
connection completion. Because high voltage is
applied to the speaker terminals, never touch these
terminals to avoid electric shock.
Be sure to ground to the safety ground (earth)
terminal to avoid electric shock. Never ground to a
gas pipe as a catastrophic disaster may result.
Avoid installing or mounting the unit in unstable
locations, such as on a rickety table or a slanted
surface. Doing so may result in the unit falling
down, causing personal injury and/or property
damage.
When the Unit is in Use
Should the following irregularity be found during
use, immediately switch off the power, disconnect
the power supply plug from the AC outlet and
contact your nearest dealer.
Make no further attempt to operate the unit in this
condition as this may cause fire or electric shock.
If you detect smoke or a strange smell coming
from the unit.
If water or any metallic object gets into the unit
If the unit falls, or the unit case breaks
If the power supply cord is damaged (exposure of
the core, disconnection, etc.)
If it is malfunctioning (no tone sounds.)
To prevent a fire or electric shock, never open nor
remove the unit case as there are high voltage
components inside the unit. Refer all servicing to
your nearest dealer.
ITC
ITC
Do not place cups, bowls, or other containers of
liquid or metallic objects on top of the unit. If they
accidentally spill into the unit, this may cause a fire
or electric shock.
Do not insert nor drop metallic objects or
flammable materials in the ventilation slots of the
unit's cover, as this may result in fire or electric
shock.
SAFETY PRECAUTIONS

An all-pole mains switch with a contact separation of at least 3 mm in each pole shall beincorporated in
the electrical installation of the building.
When Installing the Unit
Never plug in nor remove the power supply plug
with wet hands, as doing so maycause electric
shock.
When unplugging the power supply cord, be sure
to grasp the power supply plug; never pull on the
cord itself. Operating the unit with a damaged
power supply cord may cause a fire or electric
shock.
When moving the unit, be sure to remove its power
supply cord from the wall outlet. Moving the unit
with the power cord connected to the outlet may
cause damage to the power cord, resulting in fire or
electric shock. When removing the power cord, be
sure to hold its plug to pull.
Do not block the ventilation slots in the unit's cover.
Doing so may cause heat to build up inside the unit
and result in fire.
Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.
When the Unit is in Use
Do not place heavy objects on the unit as this may
cause it to fall or break which may result in
personal injury and/or property damage. In
addition, the object itself may fall off and cause
injury and/or damage.
Make sure that the volume control is set to
minimum position before power is switched on.
Loud noise produced at high volume when power is
switched on can impair hearing.
Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
Contact your dealer as to the cleaning. If dust
is allowed toaccumulate in the unit over a long
period of time,a fire or damage to the unit may
result.
ITC
If dust accumulates on the power supply plug or in
the wall AC outlet, a fire may result. Clean it
periodically. In addition, insert the plug in the wall
outlet securely.
Switch off the power, and unplug the power supply
plug from the AC outlet for safety purposes when
cleaning or leaving the unit unused for 10 days or
more. Doing otherwise may cause a fire or electric
shock.

3. OPERATION
1. Equalizer adjustment method:
Subwoofer 20Hz-40Hz, appropriate, powerful sound. Able to control thunder, bass
drum, organ and bass sounds. Will enhance the music becomes too turbid.
Bass 40Hz-150Hz, a sound basis for part of its energy accounts for 70% of the
audio energy is the important component of the performance of musical styles.
Appropriate, proper relaxation bass, voice full soft, low voice thin, 150Hz, over time
will enhance the sound of nausea, decreased brightness, increased nasal.
Bass 150Hz-500Hz, a sound structural elements, the human voicein this position,
less than, the concert will be music drowned the sound,sound soft and weak,very
vigorous when appropriate to enhance effective and improve the sound intensity and
loudness. Will increase when the bass becomes too stiff, 300Hz at the excessive
increase 3-6dB, if coupled with reverb, would severely affect the clarity of the sound.
Alto 500Hz-2KHz,contains most of the instruments of the low-order harmonics and
overtones,is a snare drum and percussion sound characteristics. Appropriate, thorough
sound bright, low sound dim. Improve over the phone when you have a similar sound.
Alt: 2KHz-5KHz, the strings, and the characteristics of sound (pull string in the bow and
the string sound of the friction and shoving, playing the pull string music the sound of a
finger).Insufficient penetration of the sound down, too strong language when
masking syllable recognition.
Treble: 7KHz-8KHz,is the layering of sound frequency.Excessive increase will piccolo,
flute,prominent voices, the language and tone scared increase dental
High tone 8KHz-10KHz
When appropriate,triangle and fork set high permeability of the metal sense, the rhythm
of the sand clock clearly visible.Excessive sound will not improve the natural, easy to
burn high-frequency unit.
2.Should be balanced sweet sound
150Hz or less (bass) should be plump, soft and elastic
150Hz-50Hz (bass) should be deep and powerful are not opacity per
500Hz-5KHz (alt) should be bright, blunt and not thoroughly
5KHz above (treble) should be thin, smooth and not shrill Park
When the flat frequency response: full and natural sound and flexible, clear layer
along pleasant garden. Frequency response of multi-peak hours: the rough sound
muddy, treble harsh scared, no layering prone to feedback howling sound reinforcement

3. Characteristics of pitch frequency
30 ~ 60Hz boring without considerable loudness, the ear is difficult to feel
60 ~ 100Hz heavy 80Hz can produce very strong near the "heavy feeling"
effect,
loudness and will not give a high feeling comfortable, you can give a strong stimulus.
100 ~ 200Hz full
200 ~ 500Hz hum efforts can lead to mental anguish.
500~ 1KHz uncertain as to enhance near 800Hz 10dB, noise will obviously produce
a sense,narrow sense.
1K ~ 2KHz translucent 2800Kz luminosity relation near the maximum.
2K ~ 4Kz the formation of sharp 6800Hz wailing, sharp feeling.
4K ~ 8Kz crisp 3400Hz easily cause hearing fatigue.
8K ~ 16Kz slim> 7.5KHz pitch Qingche fine. The development trend of the equalizer
The use of digital filter called the equalizer consisting of digital equalizer, digital
equalizer can be made icons EQ, there can be made parametric EQ, you can make both,
the EQ, it is not only excellent performance indexes, easy to operate, but also at the
same time save a balanced frequency response characteristics of a variety of
purposes, be selected for different programs can be stored up to 99 frequency
response curve.
