TROUBLESHOOTING

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.
1. SAFETY PRECAUTIONS
3

An all-pole mains switch with a contact separation of at least 3 mm in each pole shall be incorporated 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 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.
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 to accumulate 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.
SAFETY PRECAUTIONS

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

It is a high-efficiency four-channel professional power amplifier with a combination of high-performance
switching power supply and class D power amplifier; Support four balanced / unbalanced inputs and
a high-fidelity circuit design with extremely low distortion THD+N<0.02% @ 1W. It adopts 2U standard
cabinet design, with high efficiency, light weight and beautiful appearance. Ideal for medium and large-
scale theaters, outdoor performances, theaters, stadiums, clubs, night clubs, entertainment venues,
bars, rental, auditorium, banquet halls and concert, etc.
2. GENERAL DESCRIPTION
1. Adopting the latest class-D power amplifier design scheme, with small distortion and high efficiency;
2. The power supply adopts switching power supply, which has high efficiency; it is soft-started at startup
to prevent large current from being absorbed into the power grid and interfering with other power-
consuming equipment.
3. Effectively suppress power supply harmonics and meet EU green power standards.
4. Intelligent peak clipping limiter can control power module and speaker system work within safe range;
5. It is more convenient for users with different demands to adopt simple interfaces, namely standard
XLR + TRS1/4" composite input interfaces.
6. There are three levels of input sensitivity optional in two-channel power amplifier, which can easily
accept wide range signal source input.
7. Stereo or bridge operation mode is optional to adaptation for different occasions.
8. Input grounding pin grounding and suspension control switch, which has noise suppression.
9. With overvoltage protection, undervoltage protection, over temperature and pressure limit, over
temperature shutdown, overcurrent voltage limit, overcurrent shutdown, DC protection, output short
circuit protection, temperature control fan, power amplifier frequency synchronization, PWM frequency
synchronization, etc.
10. Built-in recoverable unique cut-off switch.
11. The detachable structure of the panel cleans the dustproof cotton by itself.

5. Power status indicator;
6. CLP— Clipping indicator. When the (yellow) indicator light on the machine is lit by a signal, the
output signal is distorted at this time, indicating that the input signal is too large. Please reduce
the input signal.
7. PRO—Protection indicator. The first 3 seconds of booting is the machine startup process. At this
time (red) the protection light is on. If the self-test of the whole machine is normal, it start the whole
machine after 3 seconds and turn off the light. If it is in a protected state for a long time after power
on, the whole machine is faulty. Please contact your dealer.
8. SIG—Signal indicator, when the machine is normally input, the (green) indicator is on. When the
machine fails or the signal is not input correctly, the (green) indicator does not light up.
NOTE:
To prevent the fan holes from being blocked and the machine from overheating, remove the dust
filter on the panel regularly for cleaning.
Cleaning method: first remove the four screws on the panel, take out the dust filter to clean it. After
the filter is cleaned and dried, install it back to the original position.
