corresponding volume knob counterclockwise
to the two-color power sdtatus indicator is
always light blue. b. The load is too big or the
line transformer of the load does not match
(bad quality). If so, re-calculate the power of
load if it is bigger than the power of almplifier.
If the load power is bigger than the amplifier
power, then reduce the number of loads,
if not bigger than the amplifier power, line
transformer of the load (ceiling speakers,
or sound column, etc) and does not match
amplifier (voltage is not ight or poor quality)
should replace the load.
• If the two-color power status indicator turns
red, turn off for 1 minute asnd then turn it on
again. If it is still red, then the load is too heavy
or load local short circuit, please exclude the
above factors and the try again. Connect with
not load, the two-color power status indicator
is red, then the amplifier failure.
Operations
Anticlockwise rotate all the potentiometers at the
front panel to full closed, turn the unit on, after
the dual-color power status indicator is always
blue, turn right the knob of the corresponding
potentiometer, you also can adjust the 2-band
equalizer and the master output level until the
Design and product specifications are subject to change without prior notice.
output level is just fit for you. Remember that you
should reduce the input signal level when the last
one of the level indicator is always on, if not, the
unit will be overloading and the output power
signal will be clipping.
Turn the High/Low equalizer knob clockwise is raise
the treble/bass, turn the High/Low equalizer knob
anticlockwise is reduce the treble/bass. When rise
or reduce the treble/bass, should adjust (in the
opposite direction) the Master Volume to keep the
original sound volume uncharged.
This unit use 6-band knob to control the section
volume, and change the volume by choosing 6
different voltages. Must turn anticlockwise the
master output level control potentiometer 9 to the
end (close the volume control).
Turn the 6-band knob to select the volume of
each section (0 is close, 1 is min volume, 5 is max
volume). After all the three section volume is
chosen, then adjust the master volume control 9 to
right position.
Notice: It is strictly forbidden to adjust this 6-band
knob when the Volume control is not closed.
Otherswise it will damage the unit.
