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.
Do not place cups,bowls, or other containers of
liquid or metallic objects ontop of the unit. If they
accidentally spill into the unit, this maycause a
fire or electric shock.
Do not insert nor drop metallic objects orflammable
materials in the ventilation slots of the unit'scover,
as this may result in fire or electric shock.
When Installing the Unit When Installing the Unit
Should the following irregularity be found during
use, immediately switch off the power, disconnect
the power supply plug from theAC outlet and contact
your nearest dealer. Make no furtherattempt
to operate the unit in this condition as thismay 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 expose the unit to rain oran environment
where it may be splashed by water orother 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, andnever
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. Becausehigh 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 mayresult.
Avoid installing or mounting the unit in unstable
locations, such as on a rickety table or a slanted
surface. Doing so may result in theunit falling
down,causing personal injury and / or property
damage.

3
An all-pole mainsswitch with acontact separation ofat least 3mm in eachpole shall beincorporated in
the electrical installationof the building.
Never plug in nor remove the power supply plug
with wet hands, as doing so may cause 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.
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 ontrol 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. Thisis 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 to accumulate in the unit over a
long period of time, a fire or damage to the unit
mayresult.
ITC
Ifdustaccumulates onthe power supplyplug orin
the wall AC outlet, afiremay result.Clean it peri-
odically. Inaddition, insertthe plugin thewalloutlet
securely.
Switchoff thepower, andunplugthe powersupply
plugfrom theAC outletfor safetypurposes when
cleaningorleaving theunitunused for10 days or
more.Doingotherwise maycausea fire orelectric

Due to product upgrades, while some of the
features and specification in the user manual
does not match the actual functions, sorryfor
any inconvenience and thanks for your kind
understanding!

22.DC INPUT TERMINALS
These terminals are provided for the conne-
ction of backup battery.Connect a 24VDC 50A
battery source to these terminals.Make certain
the red terminal is connected to the battery's
positive (+) side,and the black terminal to the
battery's negative (-) side.
23.INPUT GAIN CONTROLS(TRIM VR)
These knobs provide continuous control of the
input levels for each of the six input channels.
When adjusting the input gain, make certain
that the levels are not set too high, or distortion
will result.
NOTE: It is safe to connect most modern dynamic
microphones or line level devices to the
channel Inputs when phantom power is
activated. However, some older ribbon
microphones may be damaged by phan-
tom power, and certain unbalanced line
level devices maymalfunction or produce
an Audible hum when phantom power is
active.
24.MIC INPUT CHANNEL 1~4
This is a special connector which will accept
either a 3-conductor XLR or a 3-conductor 1/3
jack.These inputs are suitable to receive signal
from microphones level devices.
