2.1 Installation

CAUTION: Before you begin, make sure your
amplifier 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 amps without using a cabinet,
or you may place a single amp on a surface with 12
inches of air space above the unit for convection
cooling.
NOTE: When transporting in a rack, 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 2U 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 open.
