ΣM SERIES PROFESSIONAL POWER AMPLIFIER
2.2.Cooling Description
This digital amplifier series is designed according to international 1 U size standards.
The cooling method is: pumping the outside air into inside the unit through the vents of
the front panel, and then bring out the heat through the aluminum radiator in the unit
and then out from 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 any heat-sink overheats, the detection circuit will reduce output power. If the
amplifier overheats, the temperature protection detection circuit and its circuit will
shut down and power off until it cools to a 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 machine 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 is
enough space for the fixed installation of the unit.
