Detachable IEC.  
Q Priority Connector  
3-pin Phoenix-type connector allows Input 1 or Input 5  
(28M only) to mute other input signals by contact closure.  
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.  
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.  
R. Auxiliary Power Input  
2-position terminal strip for 24 VDC ( 10%) backup power.

2.1 Installation  
2.2 How to Attach Rack Ears  
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.  
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).  
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 InputWire 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 Balanced Input  
Connector Wiring  
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.

NOTE: Custom wiring should only be performed by  
qualified personnel. Class 2 wiring is required.

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.  
2.6 Input Routing  
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  
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.  
To set the mixer for normal mode with no priority:  
Set the OUT CONFIG DIP switch as follows:  
1 ON  
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.  
2 OFF  
3 OFF  
4 OFF  
5 ON  
Note: The routing configuration is extremely versatile. Many configura-  
tions for additional applications not highlighted in this document can be  
created by examining the signal flow in the block diagram on page 13.  
6 OFF  
Figure 2.7 Input Routing DIP Switches  
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  
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  
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.  
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.  
To give priority to the Channel-5 input to Out 2 only:  
Set the OUT CONFIG DIP switch as follows:  
5 OFF  
6 ON  
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.  
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 sound.  
CONDITION: No power to the  
mixer.  
POSSIBLE REASON:  
POSSIBLE REASON:  
Check the fuse and replace if necessary, or  
return mixer to Crown or an authorized Crown  
Service Center for servicing.  
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.)  
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  
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.
