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.
