Air intakes with grilles and filters
Do not obstruct these air intakes!
Filters are necessary to prevent dust from entering the amplifier. The grilles are removable
for easy filter cleaning. The fan’s variable speed control ensures the proper ventilation
(according to the internal temperature) and low noise operation.
