Cooling Description
This digital amplifier series is designed according
to international 1 U size standards.
The cooling methods is: pumping the outside air
into inside the unit through the vents of the front
panel, and the bring out the heat through the
aluminium radiator in the unit and then out frim
the rear panel vents. The "smart" variable speed
DC fan is equipped in the unit, and then it can
adjust the wind speed through the temperature
detection and circuit detection for the heat sink
module. When the unit inside overheats, it will
adjust the fan speed to increase cooling efficiency
immediately.

If ant heat-sink overheats, the detection circuit
will reduce output power. If the amplifier over-
heats, the temperature protection detection
circuit and its circuit will shut down and power
off until it cools to safe temperature.
After using this unit for a period of time (not
referring to the turn-on time), if it can not meet
the cooling effect after the fan running with high
speed for a long time, please turn off the ma-
chine and remove the mesh enclosure to clean
up the dust (only for the unit with the mesh
enclosure design).
The air flow diagram of the unit cooling is shown
as below, please ensure that there ir enough
space for the ixed installation of the unit.
