3 Installation preparation
Warning: before installation, please confirm that you see and read
the safety warning.
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.
For the normal operation, following parts is needed:
1
、
Input connection cable
2
、
Output connection cable
3
、
Ethernet cable (for Ethernet interface power amplifier)
4
、
Cabinets or equipment mounting rack
Before installation,make sure that the power cord is not connected to the
power outlet;The power switch is turned off;The volume knob is
completely.
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
℃
environm
ent, and ensure that the front and rear panel airway
open. If the temperature exceeds 85 degrees, outp
ut voltage will be reduced, avoid excessive tempera
ture rise. If the temperature continues rise up to 90
degrees, the power amplifier will be shunted down,
when the temperature dropped to a safe temperat
ure, the equipment will restart automatically.
After working for some time, if the cooling effe
ct is not good, please turn off the equipment and re
move 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!
