1. SAFETY PRECAUTIONS

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.

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

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.

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.

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.

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!

2. GENERAL DESCRIPTION

This range of power amplifiers are designed for general commercial and industrial public address ap-

plications. Rack mount design in 2U type, rated power ranges from 60W to 240W which provides a

wide selection to meet different size sound system needs. Both balanced and unbalanced line inputs

make it selectable for installer, balanced line output feeds to another power amplifier as well as secu-

res the signal transmission is less noise and longer distance. 70V, 100V and 4-16ohm speaker outputs

are convenient for installation when selection different speaker matching. A master volume control is

included. Complete protection includes clip, short circuit, high temp and overload. Indications for

power,signal, clip, protection and temp.

3. FEATURES

1. Rack mount amplifier in 2U type

2. Rated power from 60W to 240W

3. 70V, 100V and 4~16ohm speaker outputs

4. solated transformer for human safety operation

5. Balanced XLR type line input and unbalanced 1/4 inch TRS phone jack line input

6. Balanced XLR type line output feeds to another power amplifier

7. Reliable protection of over heat, over load, clip & short circuit.

8. Indications for power, signal, clip, protection and temp

4. PROT

The protection indicator will be light on when the constant output is 160% higher than the rated

output, the output will be cut to protection the amplifier from damage. This indicator will be

extinguished when amplifier is under normal working conditions.

High impedance and low impedance both speaker output for different application use. Only choose one of the positive end from 4~16 & 70V& 100V, then connect the negative end"COM" and one the positive end to the speaker's according ends. High impedance speaker output only for high impedance speaker connection and low impedance speaker output only for low impedance speaker connection. Speaker total power output shall be no higher than 80% percent of the amplifier rated power output.

Notice:

No mixing connected the positive and negative ends between the amplifier and loudspeaker.

Never allowed to use more than one output among 4~16 /70V/100V.

Speaker continuous power output never higher than 80% of the amplifier rated power output.

Never connect high impedance output to low impedance speaker nor connect low impedance output to

high impedance speaker.

Please cover the speaker output ends after wiring to avoid any touch. The speaker output are high voltage, never touch by human body to avoid electricity shock.

plug on the connected-ground wire-net

As formidable shock or impact on machine s-

uch as (thunder shock, halfway signal pause,

excess rated signal input or other interference),

the machine will auto-check and restart auto-

matically.
