Install Your Amplifier
CAUTION：
Before you begin, make sure your amplifier is disconnected from the power source,
with power switch in the “off” position and all level controls turned completely down
(counter clockwise).
Use a standard 19-inch (48.3 cm) equipment rack. You may also stack amps without
using a cabinet.
NOTE：
When transporting, amplifiers should be supported at both front and back.
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 or rear 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.
