2.3 Cooling
Never block the side vents and front air intake of the amplifier. Allow at least
45 cubic feet (1.3 cubic meters) per minute of air flow per amplifier. All empty
rack spaces should be covered with blank panels to prevent improper
recirculating air flow. The air flow should be augmented with a rack cooling
system if the amplifier must operate at consistently high output levels.
When mounting the amplifier in a rack cabinet, the side walls of the rack
should be at least 2 inches (5 cm) away from the chassis as shown in
Illustration 2–1.
If the rack cabinet has a front door that could block air flow to the amplifier's
air intakes, provide adequate air flow either with a grille in the door or by
pressurizing the air behind the door. See Illustration 2–2. Wire grills, as
opposed to perforated grilles, are recommended for this application, because
they tend to cause less turbulence.
