3.1 Unpack Your Amplifier
Please unpack and inspect your amplifier for
any damage that may have occurred during
transit. If damage is found, notify the
transpor tation company immediately. Only you

WaRNiNg: Before you start to set up
your amplifier, make sure you read and
observe the important Safety instruc-

manual.
3.2 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 (counterclock-
wise).
Use a standard 19-inch (48.3 cm) equipment
rack. See Figure 3.1 for amplifier dimensions.
You may also stack amps without using a
cabi net.
NOTE: When transporting, amplifiers should be
supported at both front and back.
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 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.
