3.3 Ensure Proper Cooling

When using an equipment rack, mount units
directly on top of each other. Close any open
spaces in rack with blank panels. DO NOT block
front, rear or side air vents. The side walls of the
rack should be a minimum of two inches (5.1
cm) away from the amplifier sides, and the back
of the rack should be a minimum of four inches
(10.2 cm) from the amplifier back panel.
