The environment must be dry and dustless. Do not expose the unit to rain or water splashes,and do not place liquid containers or incandescent objects like candles on top of the unit. Do notobstruct the ventilation grids with any kind of material.In case there is some type of intervention and/or connection-disconnection of the amplifier, itis most important to previously disconnect the mains power supply. There are no user or serviceableparts inside the amplifier.You should avoid that the supply cable twists with the shielded signal cables, as this couldlead to unwanted hum.The indicated situations can produce hum noise. To avoid this, the AMPACK series wears anadditional high pass filter with fixed cut-off frequency at 100Hz. This filter can be easily activated using ajumper as shown on the configuration diagram.In order to protect the unit from an eventual electrical overload or momentary power peaksfrom the internal circuits it carries a fuse. Should it ever blow up, unplug the unit from mains andreplace it with an identical one.
