Please ensure that the back voltage showing is according with the local voltage
This unit have voltage selector, can be used for different voltage
Before operation, please chck the local voltage is optional for the 110/220V selector voltage,
you can connect it if correct and optional. If not optional, please put the selector to the correct
voltage value, please note cut off the power supply when select.
The operation as:
230V
THIS IS OPTIONAL FOR 220V
115V
THIS IS OPTIONAL FOR 110V
Be sure that the power input socket is good, power cable is not damaged when
connecting, Please power off when not using unit.
The normal working voltage is 250VA, the peak power cost about 600VA.
When selected to 220V, please use 2.5A 5*20mm delay style fuse
When selected to 110V, please use 5A 5*20mm delay style fuse
Please use the correct fuse when voltage power changed
Note that the voltage will be put to 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 is short circuit or loading is too low
c check the local voltage is same as the require 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 place clockwise
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 and sound source equipment
PLEASE OBEY THE FOLLOWING:
3 Volume adjust
Connect the input signal and open the sound source,adjust the volume,if the indicator
is not lit up,please check the sound source.Adjust according to the voltage output and
the signal.When 0dB output voltage is lit up,the output is RMS, if is too much,will cause
the distortion
4 Area setting
Six buttons and six yellow indicators, when the six indicators are lit up, 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-3240 Completed functions give the amplifier and 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 back to home
PROTECTION FUNCTIONS
when exist the short circuit,it will be off automatically
it will be off automatically when input impedance is too low
if the temperature heatsink is over the standard degree.
