2.1 Installation
side walls of the rack should be a minimum of two
inches (5.1 cm) away from the mixer-amplifier
sides, and the back of the rack should be a mini-
mum of four inches (10.2 cm) from the mixer-
amplifier back panel.
CAUTION: Before you begin, make sure your
mixer-amplifier is disconnected from the
power source, with the power switch in the
“off” position and all level controls turned
completely down (counterclockwise).
2.2 How to Attach Rack Ears
Use a standard 19-inch (48.3 cm) equipment rack
(EIA RS-310B). See Figure 2.1 for amplifier dimen-
sions.
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.
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

2.3 Choose Input Wire and Connectors
Crown recommends using pre-built or professionally wired bal-
anced 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 140MPA 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 (Figure
2.4).
• Transformer-isolated 600-ohm input: 3-pin Phoenix-
type. Summed into Input 1 for paging from a telephone system.

AMPLIFIER OUTPUTS
Amplifier Output Connections: Slip the cable lugs under the
output screw terminals and tighten (Figure 2.6). Cover the output
connections with the supplied non-touch cover.
Crown recommends using pre-built or professionally wired,
high-quality, two-conductor, heavy gauge speaker wire and con-
nectors. You may use crimp-on spade lugs for your output con-
nectors. To prevent the possibility of short-circuits, wrap or
otherwise insulate exposed loudspeaker cable connectors. Cover
the output connections with the supplied non-touch cover.
Using the guidelines below, select the appropriate size of wire
based on the distance from amplifier to speaker. The wire sizes
apply to the 4-ohm tap.

Music-On-Hold Connections
If you have an external FM or XM tuner connected to the
140MPA, you can play its music over a phone line while
the caller is on hold. Use one of the connectors below to
connect the 140MPA to the Music-On-Hold input on your
telephone system interface/PBX.
CAUTION: Never use shielded cable for output power
wiring.
Use 2-conductor shielded cable and a 3-pin Phoenix-type con-
nector for Preamp Line Output (Figure 2.7), and for MOH 1V or
1W output (Figure 2.8).
• MOH 1V Line Output Phoenix Connector: 3-pin
Phoenix connector, 600-ohm transformer-isolated output,
provides Music-On-Hold signal of approximately 1 volt.
See Figure 2.8.
Use 1-conductor shielded cable and RCA plugs for the MOH 1V
Line Output RCA Connector (Figure 2.9).
• MOH 1W Line Output Connector: 3-pin Phoenix
connector provides Music-On-Hold signal of approxi-
mately 1 watt. See Figure 2.8.
To telephone system

• MOH 1V Line Output RCA Connectors: Two RCA
connectors (mono) for 1-volt Music-On-Hold output (in

2 Setup
2.5 Wire Your System
Typical input and output wiring is shown in Figure 2.10.
INPUTS: For Input 1, connect a microphone or balanced line-level
signal to the Input 1 balanced input. Set the Mic/Line switch accord-
ingly. Connect unbalanced line-level signals to the RCA input con-
nectors.
Satellite Receiver
For Inputs 2-4, connect a balanced line-level signal to the balanced
input. Connect unbalanced line-level signals to the RCA input con-
nectors.
OUTPUTS: Maintain proper polarity (+/–) on amplifier output con-
nectors.
Connect the Amplifier Output screw terminals to the loudspeaker
loads. Use terminals marked COM and 70V or 100V for constant-
voltage loudspeaker loads. Use terminals marked COM and 4 ohms
for 4-ohm speakers.
Connect the COM terminal to speaker negative (–) lead; connect one
of the other terminals to speaker positive (+) lead.
2.6 Phantom Power
Condenser mics require phantom power to operate. If you are using a
condenser microphone on Input 1, turn on the Phantom Power
Switch on the back of the 140MPA. The microphone must be able to
work on 15V phantom power, which the 140MPA mic input connector
provides.
2.7 Link In/Out Switch
This switch (Figure 2.11) affects which signals are heard when
another mixer is wired to the 140MPA.
IN: Any signal applied to the AMP INPUT connector will be mixed
with the input signal(s).
OUT: Only the signal from the AMP INPUT connector will appear at
the amplifier output.
Figure 2.10 Input and Output Wiring
How to link another mixer to the 140MPA:
Connect the extra mixer’s LINE OUT connector to the 140MPA AMP
INPUT connector. Set the Link switch to IN.
How to set up Music-On-Hold output:
Connect 140MPA LINE OUT to the Music-On-Hold input on a tele-
phone system interface/PBX. Set the LINK SWITCH to IN.

Crown 1-VCAP level control to the Phoenix-type cable connector ter-
minals as shown in Figure 2.12.

3 Operation
3.1 Powering Up
1. Turn off any equipment connected to the Line Out connectors.
2. Plug the amplifier’s power cord into a 3-wire grounded AC outlet.
3. Turn down the input volume controls.
4. Turn down the master volume control.
5. Turn on the Power switch. The Power indicator should glow.
6. Turn the input volume controls in use about 3/4 up.
7. Turn up the master volume control(s) until the desired loudness or power
level is achieved.
8. Touch up the input levels as needed for equal loudness from each micro-
phone.
9. Turn on any equipment connected to the Line Out connectors.
If you ever need to make any wiring or installation changes, disconnect the
power cord.
Figure 3.1 Priority Ducking Controls
and Connectors
3.2 Priority Ducking
If you want a microphone to duck (turn down) the background music or other
input signals, follow this procedure. On the back of the 140MPA,
1. Connect a push-to-talk mic contact to the Priority Connector (Figure 3.1).
Input 1 is the priority input for the amplified output, so Input 1 ducks the other
inputs. Threshold of activation depends on input voltage. Ducking does not
affect MOH outputs.
2. Adjust the VOX Threshold trim pot on the back of the unit to set how loud
the voice must be before ducking occurs. It can be set for no ducking.
3. Adjust the Priority Release trim pot for the desired ducking release time.
The Active Indicator lights when ducking is active.
3.3 Music-On-Hold
On the back of the unit, adjust either the 1V or 1W MOH Level Control to obtain
the desired level of Music-On-Hold on your phone system.

4 Troubleshooting
CONDITION: No sound.
CONDITION: No power to the
mixer-amplifier.
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 of the unit. If that does not work, return
the unit to Crown or an authorized Crown Ser-
vice Center for servicing.
•
•
The mixer-amplifier’s Power switch is off.
[NO GRAPHIC IS NEEDED
HERE]
The mixer-amplifier is not plugged into the
power receptacle.
•
The mixer-amplifier’s high-voltage power sup-
ply 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 LEDS to illuminate con-
stantly.
•
Master volume level is too high. Turn it down
to about 3/4 of maximum level.
