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 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 shaky 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 Mixhits Audio dealer. Do not attempt to
operate the unit in this condition as this may cause
fire or electric shock.
•If you detect smoke or an odor 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.
•If it is malfunctioning (no sound.)
• To prevent a fire or electric shock, never open or
remove the unit case as there are high voltage
components inside the unit. Refer all servicing to
your Mixhits Audio dealer.
•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 or 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 the
minimum position before the power is switched on.
Loud noise produced at high volume when power is
switched on can damage 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.
•If dust is allowed to accumulate in the unit over a
long period of time, a fire or damage to the unit
may result. Contact your Mixhits Audio dealer to
schedule a cleaning of the unit.
•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 several days. Doing otherwise may
cause a fire or electric shock.

SAFETY PRECAUTIONS
1. FEATURES
1. Rated Power:60W /120W.
2. 100V / 70V constant voltage outputs and 4~16Ohms constant resistance output.
3. Commercial-grade torroidal transformers produce high performance audio on a wide range of
frequencies with min noise and high fidelity, even at high volume.
4. Reliable protection against overload, short ciruit, and power fluctuation for optimum
reliability.
5. VOX feature mutes AUX inputs when input is detected on MIC 1. Time Adjust control allows
resumption of music to be sharp or gradual.

Be sure to reattach the supplied terminal cover after connecting speakers to avoid
risk of shock. Never touch the terminals.
MUTE FUNCTION
1.Tel has priority over all inputs.
2.MIC 1 is secondpriority and can override all
other input signal except tel signal.
1. Check all inputs and
mute functions.
2. Incorrect speaker
connections.
OPERATIONWARNING
Do not use 70V/100V and the 4/16 ohm outputs at the
same time. The wattage sum off all speakers when using
70V/100V should never exceed the rated total watts of
the Mixer / Amp. It is strongly suggested to only utilize
85% of the rated power to allow for headroom.
