1.3 Back Panel Controls and Connectors
J. AC Power Inlet
Detachable IEC.
K. Mixer Config Switch
A DIP switch with two functions:
1. Assigns one of the inputs as the priority input for each
output, thereby temporarily muting the remaining inputs.
Muting is activated by contact closure.
2. Global enable switch for phantom power. Does not affect
RCA inputs. Default position is off.
L. Input Routing Switch (28M only)
DIP switches that assign each input signal to each output.
Two switches per input.
M. Mic/line Switch
Selects mic-level or line-level input signals. One switch for
each balanced input.
N. Dual RCA Input Connector
For stereo music signals, unbalanced, summed together,
two connectors per input channel. If required, both the mic/
line and RCA inputs may be used at the same time. The mic/
line gain switch does not affect the RCA gain, which is fixed
relative to mic/line. The mic/line and RCA signals are mixed.
Note: Other equipment connected to the RCA jacks should
be connected to the same AC power source as the mixer to
avoid hum.
O. Mic/Line Input Connector
3-pin Phoenix-type, balanced, one per input channel.
P. Fuse
Protects the power supply.
Q Priority Connector
3-pin Phoenix-type connector allows Input 1 or Input 5
(28M only) to mute other input signals by contact closure.
R. Auxiliary Power Input
2-position terminal strip for 24 VDC (±10%) backup power.
Accepts up to 10 AWG terminal forks. NOTE: To prevent a
spark when attaching a battery, have unit turned on and
connected to the mains supply.
S. Line Out Connector
One 3-pin balanced Phoenix-type connector per output
channel. Level controlled by master volume control.
The tone generator has been omitted. Call Crown Tech
Support if you have tone generator questions.

2.2 How to Attach Rack Ears
CAUTION: Before you begin, make sure your
mixer is disconnected from the power
source, with the power switch in the “off”
position and all level controls turned
completely down (counterclockwise).
1. Locate the two rack ears 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 top hole
of the rack ear and chassis. Screw it in.
6. Repeat steps 3-5 for the left side of the chassis.
Use a standard 19-inch (48.3 cm) equipment rack
(EIA RS-310B). See Figure 2.1 for amplifier
dimensions.
You may also stack mixers without using a
cabinet, or you may place a single mixer on a
surface.
Figure 2.2 How to Connect Rack Ears
NOTE: When transporting in a rack, mixers should
be supported at the front and back.
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 mixer back panel.

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. You should use 3-pin Phoenix-type cable ends at
the mixer inputs. Unbalanced line may also be used but may
result in noise over long cable runs.
Figure 2.3 shows connector pin assignments for balanced wiring,
and Figure 2.4 shows connector pin assignments for unbalanced
wiring. The RCA input connectors can also be used for
unbalanced inputs.

2.6 Input Routing
In the 28M, any input can be assigned to Output 1, Output 2 or both. The
two DIP switches labeled INPUT ROUTING are used (Figure 2.7). Follow
the settings printed on the back panel next to the INPUT ROUTING switch.
For example, to send input Channel 3 to Output 1 and Output 2, turn on
DIP switches 13 and 14.
Figure 2.7 Input Routing DIP Switches
2.7 Phantom Power
To turn on phantom power on all mic inputs, turn on the switch number 7
in the AMP CONFIG DIP switch.
2.8 Priority Muting
A back-panel AMP CONFIG DIP switch (Figure 2.8) can assign Input Ch. 1
or Input Ch. 5 (28M only) as the priority input for each mixer output, which
temporarily mutes the remaining inputs. Muting is activated by contact
closures.
For example, suppose you configured Channel 1 as the priority input. Mic
1 is plugged into Channel 1. A press-to-talk switch in Mic 1 is wired to the
Priority connector in the mixer-amplifier. When you press the mic switch,
all other signals are muted so you can make an announcement on Mic 1.
One DIP-switch selection enables Channel 1 as the priority input, which
mutes all other inputs to Out 1. In the 28M only, another DIP switch
selection enables Channel 5 as the priority input, which mutes all other
inputs to Out 2. In the 28M only, another set of DIP switches enable
Channel 1 as the priority input into both Out 1 and Out 2, effectively
muting any input.
To give priority to the Channel-1 input to Out 1 and Out 2:
Set the OUT CONFIG DIP switch as follows:
1 OFF
2 ON
3 ON
4 ON
To set the mixer for normal mode with no priority:
Set the OUT CONFIG DIP switch as follows:
1 ON
2 OFF
3 OFF
4 OFF
5 ON
6 OFF
Also, wire a SPST switch to the PRIORITY connector between COM and
CH1 Out 1. Close the switch when you want the Channel-1 input to mute
all other inputs feeding Out 1 and Out 2.
Note: The routing configuration is extremely versatile. Many configurations for additional applications not highlighted in this document can be
created by examining the signal flow in the block diagram on page 13.
To give priority to the Channel-1 input to Out 1 only:
Set the OUT CONFIG DIP switch as follows:
1 OFF
2 ON
3 OFF
4 OFF
Also, wire a SPST switch to the PRIORITY connector between COM and
CH 1 OUT 1. Close the switch when you want the Channel-1 input to mute
all other inputs feeding Out 1.
To give priority to the Channel-5 input to Out 2 only:
Set the OUT CONFIG DIP switch as follows:
5 OFF
6 ON
Also, wire a SPST switch to the PRIORITY connector between COM and
CH 5 Out 2. Close the switch when you want the Channel-5 input to mute
all other inputs feeding Out 2.

2.9 Powering Up
1. Turn off any equipment connected to the Line Out connectors.
2. Plug the mixer’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. Have someone talk into a microphone. Turn up the master volume
control(s) until the output clip LED flashes, then turn down the master
volume control(s) about 1/4 turn for headroom.
8. Turn on any equipment connected to the Line Out connectors.
9. Turn up the power amplifier level control until the desired loudness or
power level is achieved.
10. Touch up the input levels as needed for equal loudness from each
microphone.
If you ever need to make any wiring or installation changes, disconnect the
power cord.

3 Troubleshooting
CONDITION: No power to the
mixer.
POSSIBLE REASON:
•
The mixer’s Power switch is off.
•
The mixer is not plugged into the power
receptacle.
•
The mixer’s high-voltage power supply circuit
fuse has opened. Verify that the AC mains
voltage is correct, then press the Reset button
on the back panel.
•
If the unit is operated from a 24V DC supply, the
internal fuse may have opened. (The power
switch has no effect on 24V operation.)
CONDITION: No sound.
POSSIBLE REASON:
•
Check the fuse and replace if necessary, or
return mixer to Crown or an authorized Crown
Service Center for servicing.
•
No input signal.
•
Input signal level is very low.
CONDITION: Distorted sound.
POSSIBLE REASON:
page 14
•
Input signal level is too high. Turn down your
input volume controls. NOTE: Your mixer
should never be operated at a level which
causes the Clip LEDS to illuminate constantly.
•
Master volume level is too high. Turn it down to
about 3/4 of maximum level.
