To assure proper operation and to avoid the potential for safety hazards, place the unit on a
firm and level surface capable of supporting 100 pounds or more. When placing the amplifier
on a shelf, be certain that the shelf and any mounting hardware can support the weight of
the amplifier and any additional items in the equipment rack, or on the shelf.
When positioning the amplifier in its final location, make certain that it has adequate
ventilation on all sides, as well as on the top and bottom. In particular, it is a good idea
to provide at least two or three inches of room above the amplifier for air circulation. DO
