2.1 Installation
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.
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.
Figure 2.2 How to Connect Rack Ears
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.

2.3 Choose InputWire 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.
MIC
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 Phoenix-
type. Summed into Input 1 for paging from a telephone system.

INSTALLING THE ANTENNA
OPERATING THE XM TUNER
You can control the XM tuner by the 180MAx front-panel buttons or by the
included remote control. If the power fails, the tuner will automatically
return to its state before power loss.
1. Connect the antenna.
Connect the included XM antenna to the XM antenna input on the back of
the 180MAx.
A display will appear similar to the one below:
The XM tuner display and controls are shown below.
You will be mounting the antenna near a south-facing wall. The antenna
comes with 20 feet of cable. If that is not sufficient to reach the 180MAx,
purchase a 50-foot cable extension kit. Up to two extensions can be used
together for up to 120 total feet of cable. Alternatively, you can use custom
lengths of 50 ohm RG58U, or obtain extension kits from third-party
sources. For outdoor antenna installation options, go to

• The Scroll knob lets you scroll through the XM channels and select

At the bottom right of the screen is a small box that indicates signal
strength. Orient the antenna to achieve maximum signal strength (fill the
box as much as possible).
2.Turn on the 180MAx.
Verify the power indicator is illuminated and the display backlight is on.
Infrared remote sensor
Scroll knob
LCD display
If the antenna does not have a clear path to the satellites, the display will
read “NO SIGNAL”.
If the message “CHECK ANTENNA” appears, check that the antenna
connector is tightly connected and that the antenna cable is not shorted.
5. Set the listening volume.
3. Align the antenna.
Turn up the XM input volume control until you hear the XM radio signal at
a low volume. If the system is working, you will hear XM programming on
channel 1 and you can proceed to activate the 180MAx.
For indoor installation on a flat surface:
Set the antenna on its base on a flat horizontal surface, ideally near a
south-facing wall, and near a window if possible.
6. Activate your XM account.
Turn the base of the antenna so that the XM logo is facing to the south if
you are in the eastern half of the U.S. and to the south/southeast if you are
in the western half of the U.S.
After verifying channel 1 audio, you must activate your XM account to
access all XM channels. Commercial accounts must sign up for and
activate under the terms of XM’s Commercial Service.
Default Display
For outdoor installation:
First obtain the XM Radio ID number of your unit. Turn the Scroll knob
until you see channel 0 on the LCD display and press the Scroll knob to
select this channel, or press Direct Entry then 0 and OK on the remote
control. The 8-digit XM Radio ID will appear in the top section of the
display.
The default display shows the current channel number, channel name,
Category name, artist name and song title. The word “Direct” appears at
the bottom left of the screen. That means the tuner is in Direct mode: you
can select channels directly from the remote control if you wish. You can
also select channels using the front-panel controls.
For indoor wall mounting:
You will mount the antenna near a south-facing wall, and near a window if
possible.
1. Insert four screws (not supplied) in the wall so they align with the
holes in the base of the antenna.
2. Tilt the antenna fully back on the base.
3. Place the antenna base on the four screw heads with the antenna pivot
at the top.
4. Pull down the base approximately 1/4 inch until the base is firmly
secured. The XM logo will be upside down when the antenna is properly
installed.
Record the 8-character ID in the space below, noting that letters I, O, S and
F are not used and that the number zero has a line running diagonally
through it.

4 Troubleshooting
CONDITION: No sound.
CONDITION: No power.
POSSIBLE REASON:
POSSIBLE REASON:
•
The amplifier is in “fault” mode. A Fault status
can be triggered when one of the amplifier’s
protection circuits is activated. First disconnect
your speakers from the affected channel(s) one
by one to determine if one of the loads is
shorted. If an amplifier channel has a thermal
fault, there will be no indication on the front
panel, but the amp will recover after cooling. If
operation does not return to normal after
restarting your amp, press the Reset button on
the back panel, or return mixer-amp to Crown or
an authorized Crown Service Center for
servicing.
•
•
The mixer-amplifier’s Power switch is off.
The mixer-amplifier is not plugged into the
power receptacle.
•
The mixer-amplifier’s high-voltage power
supply circuit breaker has tripped. Verify that
the AC mains voltage is correct, then press the
Reset button on the back panel.
•
•
No input signal.
Input signal level is very low.
CONDITION: Distorted sound.
POSSIBLE REASON:
•
Input signal level is too high. Turn down your
input volume controls. NOTE: Your mixer-
amplifier should never be operated at a level
which causes the Clip LED to illuminate
constantly.
•
Master volume level is too high. Turn it down to
about 3/4 of maximum level.
