power outlet; The power switch is turned off; The volume knob is completely
closed (counter clockwise to the limit).
The equipment is high power, around a strong magnetic field. Keep the
signal sensitive equipment away (preferably not less than 20cm),
ortherwise may produce noise.

3.4 Cooling instructions
The cooling mode of the equipment is as follow:
the cold air is sucked through the ventilation hole of
the front panel, and the heat are taken out from the
rear panel. In order to ensure good heat dissipation,
please put the equipment in the 0
℃
~40
℃
environment,
and ensure that the front and rear panel airway open.
If the temperature exceeds 85 degrees, output voltage
will be reduced, avoid excessive temperature rise. If
the temperature continues rise up to 90 degrees, the
power amplifier will be shunted down, when the
temperature dropped to a safe temperature, the
equipment will restart automatically.
After working for some time, if the cooling effect
is not good, please turn off the equipment and remove
the dust net cover to clean up the dust.
3.5 Power cord
The grounding end of the power cord must be grounded,
otherwise there is a risk of electric shock!
PROFESSIONAL
POWER
AMPLIFIER
The power cord must have sufficient current capacity, AC power supply voltage and frequency
must be in range of ±10% of the nominal value.
