2.1 Installation
2.2 How to Attach the Unit to a Rack
CAUTION: Before you begin, make sure
your mixer-amplifier is disconnected from
the power source, with power switch in the
“off” position and all level controls turned
completely down (counterclockwise).
1. Order the optional Rack-Mount Kit from your
Crown dealer. Part no. RM1 is a “single rack mount
kit” for mounting a single MA unit in a rack. Part
no. RM2 is a “double rack mount kit” for mounting
two MA units side-by-side in a rack.
Use a standard 19-inch (48.3 cm) equipment rack
with an optional rack-mount kit. See Figure 2.1 for
dimensions.
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.
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.
4. Insert a screw that you removed into the bottom
hole of the rack ear and chassis. Screw it in.
Figure 2.2 How to Connect Rack Ears
(Not to Scale)
5. Insert a screw that you removed into the center
hole of the rack ear and chassis. Screw it in.
NOTE: When transporting in a rack, mixer-amps
should be supported at the front and back.
6. Insert one of the supplied screws into the top
hole of the rack ear and chassis. Screw it in.
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 mixer-ampli-
fier sides, and the back of the rack should be a
minimum of four inches (10.2 cm) from the mixer-
amplifier back panel.
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, 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.
PRIORITY
The 135MA and 160MA have two types of input connectors:
Phoenix-type and RCA.
• Mic/Line Connector (CH1): 5-pin Phoenix-type, balanced,
pins 3, 4 and 5 (Figure 2.3).
• Dual RCA Input Connector (other channels): For stereo
music signals, unbalanced, summed together, two connectors per
input (Figure 2.4).

Crown recommends using pre-built or professionally wired, high-qual-
ity, two-conductor, heavy gauge speaker wire and connectors. You may
use crimp-on spade lugs for your output connectors. To prevent the pos-
sibility of short-circuits, wrap or otherwise insulate exposed loudspeaker
cable connectors. Cover the output connections with the supplied clear
non-touch cover by sliding the cover on.

Use 2-conductor shielded cable and a 3-pin Phoenix-type connector for
Preamp Line Output (Figure 2.7).

Music-On-Hold Connections
If you have an external music source connected to the 135MA or
160MA, you can play its music over a phone line while the caller is on
hold. Use the connection shown in Figure 2.8 (either 8 ohms or 600
ohms) to connect the mixer-amp to the Music-On-Hold input on your
telephone system interface/PBX.
To telephone system
interface/PBX input
If your phone system needs to be electrically isolated from the 135MA
or 160MA, you can order an accessory isolation transformer from your
Crown dealer, part no. IST. It connects either to the MOH output or to
Input 1.

3.1 Powering Up
1. Turn off any equipment connected to the Preamp Output connector.
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 music and voice.
9. Turn on any equipment connected to the Preamp Output connector.
If you ever need to make any wiring or installation changes, disconnect the power cord.

PRIORITY
3.2 Priority Muting
If you want a microphone’s push-to-talk switch to mute the background music or other input
signals, follow this procedure. On the back of the 135MA or 160MA,
1. Turn DIP switch 2 off. Turn DIP switch 3 on.
2 . 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 mutes the other inputs.
3.3 Voice-Activated (VOX) Muting
If you want a voice to mute the background music or other input signals, follow this proce-
dure. On the back of the 135MA or 160MA,
Mic push-to-talk switch
1. Turn DIP switch 4 on. Turn DIP switches 2 and 3 off.
2. Talk into the microphone. Adjust the VOX Threshold trim pot on the back of the unit to set
how loud the voice must be before muting occurs. It can be set for no muting.
Figure 3.1 Priority Muting Controls and Connectors
3.4 Music-On-Hold
On the back of the unit, adjust MOH Level Control to obtain the desired level of Music-On-
Hold in your phone system.
3.5 Security Knobs
To prevent user tampering with the knobs, you can order the accessory 10-pack of security
knobs from your Crown dealer, part no. S-Cover.
1. Pull off an existing knob.
2. Remove the nut.
3. Screw the security knob over the potentiometer shaft. The knob will not rotate.

4 Troubleshooting
CONDITION: No power to the
mixer-amplifier.
CONDITION: No sound.
POSSIBLE REASON:
POSSIBLE REASON:
• The mixer-amplifier’s Power switch is off.
• 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
Service Center for servicing.
• 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.
CONDITION: Distorted sound.
CONDITION: No sound.
POSSIBLE REASON:
POSSIBLE REASON:
• Input signal level is too high. Turn down your
input volume controls. NOTE: Your mixer- am-
plifier should never be operated at a level which
causes the Clip LEDS to illuminate constantly.
• No input signal.
• Input signal level is very low.
CONDITION: Distorted sound.
