MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equip­ment such as preamplifiers or tape decks directly
above or below the unit. Because this amplifier has
a high power density, it has a strong magnetic field
which can induce hum into unshielded devices that
are located nearby. The field is strongest just above
and below the unit.

If an equipment rack is used, we recommend locat­ing the amplifier(s) in the bottom of the rack and the
preamplifier or other sensitive equipment at the top.

Commercial Audio Series Business Music System

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 com­pletely down (counterclockwise).

Use a standard 19-inch (48.3 cm) equipment rack
(EIA RS-310B). See Figure 2.1 for amplifier dimen­sions.

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.

2.2 How to Attach Rack Ears

1. Locate the two rack ears and two rack-ear screws
supplied.

2. See Figure 2.2. Remove the two screws from each
side of the chassis near the front.

3. Place a rack ear flush with the right front of the
chassis.

4. Insert a screw that you removed into the bottom
hole of the rack ear and chassis. Screw it in.

5. Insert a screw that you removed into the center
hole of the rack ear and chassis. Screw it in.

6. Insert one of the supplied screws into the top hole
of the rack ear and chassis. Screw it in.

7. Repeat steps 3-6 for the left side of the chassis.

2.3 Choose Input Wire and Connectors

Crown recommends using pre-built or professionally wired bal­anced line (two-conductor plus shield), 22-24 gauge cables and
connectors. Unbalanced line may also be used but may result in
noise over long cable runs.

The 180MAx has two types of input connectors: Phoenix-type
and RCA.

• Mic/Line Connectors and Amp Input Connectors: 3-pin
Phoenix-type, balanced, one per input channel (Figure 2.3).

• Dual RCA Input Connector: For stereo music signals,
unbalanced, summed together, two connectors per input for
inputs 1, 2 and 3 (Figure 2.4).

• Transformer-isolated 600-ohm input: 3-pin Phoenix­type. Summed into Input 1 for paging from a telephone system.
See Figure 2.5.
