INTRODUCTION
Thank you for selecting a Peavey Pro Comm PCX-
U12 quartz controlled single channel true diversity wireless
microphone system. Before operating and installing this
system please read this instruction manual carefully and
thoroughly in order to attain the correct operating
procedures and to achieve the best results.
True Diversity Receiver
The Peavey Pro Comm PCX-U12 quartz controlled
receiver is a true diversity wireless system. This system is
also equipped with “Superior frequency tracking and muting
techniques” that is effective in eliminating the random noise
interference when the receiver is in standby state. The
Peavey Pro Comm PCX-U12 receiver is equipped with both
balanced and unbalanced outputs.
This system includes the following accessories:
• AC/DC Adapter
• Mic Clip
• Antenna (2)
• Instruction Manual

2. Power Switch and Indicator:
When the switch is turned on the red indicator
illuminates to denote normal power status.
3. RF Signal Level Indicator:
Indicates the RF signal strength received from the
microphone. As soon as the signal is emitted from
the microphone the LED indicator illuminates.
4. Audio Signal Level Indicator:
Indicates the audio signal level. As soon as the
microphone signal is modulated, the LED indicator
illuminates.
5. Volume Control:
Adjusts the AF output level of the receiver.

7. DC 12V Input Jack:
Connect the 12V DC plug from the AC/DC adapter.
8. Balanced Audio Output Jack:
XLR type connector
9. Unbalanced Audio Output Jack:
1/4" Phone Jack
10. Unbalanced Level Switch:
“LOW selection is for “Microphone-Level” output.
“HIGH” selection is for “Line-Out” level output.
11. Squelch Adjustment:
Adjust the squelch level to eliminate the RF noise
interference at the receiver.
2. INSTALLATION OF THE RECEIVER
1. Install one of the antennas at the antenna input
connector A. Then install the other antenna at
the antenna input connector B.
2. AC/DC Power Connection:
Figure 3
Connect the AC/DC adapter cable to the DC 12V
input jack. Then plug the adapter unit into an
appropriate AC outlet as shown in Figure 3. Caution:
Make sure the correct voltage is present at the AC
outlet as indicated on the AC/DC adapter.

3. Audio Output Connection:
a. Unbalanced Level Switch Setting Position:
Make sure to match the unbalanced output
setting to the device input setting. The
incorrect setting could result in low sensitivity
level or over load distortion. Ex. (If you are
going into the “Line” input on a mixer or
amplifier then the switch should be set to the
high position. If you are going into the “Mic”
input of an amplifier or mixer then the switch
should be set to the low position.)
b. Unbalanced Output:
Connect the 1/4" phone plug of the audio cable
into the unbalanced output connector on the
back of the receiver. Connect the other end of
the cable to the proper input of the desired
device. Make sure the unbalanced level switch
is in the proper position before applying power.
c. Balanced Output:
Connect the male XLR connector into the
balanced output connector on the back of the
receiver. Connect the other end of the cable
into the “Mic/Balanced” input of the desired
device. The characteristics of the 3-pin XLR
connector are shown below in Figure 4.

3. TWO 19/2-INCH UNITS RECEIVER INSTALLATION
A. Setup for single half-rack receiver
1. Push the rack mount brackets (RM-11)
upwards until it is firmly attached to the
receiver. (Figure 5)
Figure 5
B. Setup for dual half-rack receivers
1. Remove the screws at the top and
bottom of the receiver where they will
be joined together. Remove one steel
plate from each receiver. Push the
receivers next to each other. Refer to
Figure 6.
2. Insert the steel plate in between the two
receivers (top and bottom). Align and
fasten the screws tightly as shown in
Figure 6.
3. Align and fasten the rack mount
7
brackets (RM-12) on the outer sides of
both receivers as shown in Figure 6.
Figure 6
4. After completion, it can be rackmounted
into an EIA standard rack case. Shown
in Figure 7.
5. Make sure that the system performs
correctly by placing the system away
from noise sources. Place the receiver
at least one meter above the ground
and one meter away from noise
sources. Place the microphone at least
one meter away from the receiving
antenna, as shown in Figure 8.
