.Do not open the cover because existdangerous voltage,please ask theprofessional to repair
Do not expose it to the raining ormoisture.
Do not put it under the direct sunshine, hightemperature or heat source.
Keep good ventilation, not stop the ventilating hole.
Note the local voltage must matched withthe voltage required.
Please put off the plug if not use for a long time.
Connect with right load, not work under overload for a long time.
Do not let the obstacle into the unit,keep the unit away the obstacles.
Please stop using if the cable is damaged.
The equilateral triangle with lightning bolt warnsthe user of dangerous voltage levels
localized within the cabinet.
The equilateral triangle with exclamatory mark meansthe important operation on the
user's manual.
Symbols:
BA is a integrated amplifier with completed functions,can meet the demand of
small public address system separately.
series
1 > Five channels input
INPUT1-INPUT4 can be choosed to be balanced microphone input with low impedance,
built-in 24V eidolon power microphone inputor line balance input with high impedance.

other channel output
2 > Balanced rated voltage outputwith 100V 70V, 4 Ohms rated impedance output .
3 > Separately volume controlfor each channels,the total volumecontrol is also available
and convenient
4 > HF/LF adjust
5 > Separated areas with Six channels
6 > The DC 24Vinterface is available under the urgent situation to provide the power supply
when the local voltage has problems
7 > Power supply isoptional for 110V/220V
8 > Auto power off function underOutput short circuit, over loading, overheatprotection
9 > Include DC24V/1A output port, it can provide 24Vmaximum 1A for outside devices.

Please ensure that the back voltageshowing is according with the localvoltage.
This unit have voltage selector, can be used for different voltage.
Before operation, please chck the localvoltage is optional for the 110/220V selectorvoltage,
you can connect it if correct and optional.If not optional, please put the selector to thecorrect
voltage value, please note cut offthe power supply when select.
The operation as:
230V
THIS IS OPTIONAL FOR 220V
115V
THIS IS OPTIONAL FOR 110V
Be sure that the power inputsocket is good, power cable isnot damaged when
connecting, Please power off when notusing unit.
The normal working voltage is 250VA(BA5120/125VA), the peakpower cost about
600VA(BA5240/300VA).
When selected to 220V, please use 2.5A(BA5120/1.5A) 5*20mm delay style fuse
When selected to 110V, please use 5A(BA5120/2.5A) 5*20mm delay style fuse
Please use the correct fuse when voltage power changed
Note that the voltage will be putto 220 when leaving factory

OPERATIONS
1 Start
a set the right function and connect the right cable
b check the output line and see if it isshort circuit or loading is too low
c check the local voltage is same as therequire of power
d adjust the volume to Min
e connect the power supply,then open the sound source, pre and effect equipments,
must sure all equipments work well.
f Open the power supply,and sure the indicator is lit up.
g Adjust the volume to right placeclockwise
2 Put off
a adjust volume to Min. counter-clockwise
b put off the power supply, and sure the indicator off
c put off the pre and effect equipments andsound source equipment
PLEASE OBEY THE FOLLOWING:
3 Volume adjust
Connect the input signal and open the sound source, adjust the volume, ifthe indicator
is not lit up, please check thesound source. Adjust according to the voltage output and
the signal. When 0dBoutput voltage is lit up, theoutput is RMS, if is too much, willcause
the distortion.
4 Area setting
Six buttons and six yellow indicators, when the six indicators are litup, it means that
there are output in six areas, press the area button, the relative area will be closed and
the indicators will be off.
BA Series Completed functions give the amplifierand speaker a good protection to avoid
the damage, like short circuit,overloading,and overheat.
1 Circuit protect:
2 Cverload protect:
3 Overheat protection:
If the unit will be back to required range, the nuit will be backto home.
PROTECTION FUNCTIONS
when exist the short circuit, it will be off automatically.
it will be off automatically when input impedanceis too low.
if the temperature heat sink isover the standard degree.
