Setup; Installation; How To Attach Rack Ears - Crown 180MAx Pack Operation Manual

2 Setup

2.1 Installation

CAUTION: Before you begin, make sure your
180MAx is disconnected from the power
source, with the power switch in the "off"
position and all level controls turned com-
pletely down (counterclockwise).
Use a standard 19-inch (48.3 cm) equipment rack
(EIA RS-310B). See Figure 2.1 for amplifier dimen-
sions.
You may also stack mixer-amps without using a
cabinet, or you may place a single mixer-amp on a
surface with 12 inches of air space around the unit
for convection cooling.
NOTE: When transporting in a rack, mixer-amps
should be supported at the front and back.
When using an equipment rack, do not mount units
directly on top of each other. Allow 2 rack units (3.5
inches) between units for convection cooling. 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.
