Crown amplifiers draw air in the front and exit out the sides (CE Series and Contractor Series (CH/CL Series) amplifiers exit air out the back). For this reason do not install auxiliary fans POINTING IN toward the amplifiers. The following are two suggestions:
- Place the fan in the back of the rack pointing out or away from the amplifier(s)
- Seal the back of the rack with the road case cover. Mount the fans to the TOP of the road case back cover POINTING OUT.
