INTRODUCTION Thank you for selecting a Peavey Pro Comm PCXU302 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-U302 quartz controlled receiver is a true diversity wireless system.
1. Antenna Input Connector A 2. Power Switch and Indicator: When the switch is turned on the red indicator illuminates to denote normal power status. 3. Group Selector: Selects a group of frequencies. 4. Channel Selector: Selects a channel within a group. There are six group numbers available. Groups one through four each have six available channels (one through six). Groups five through six each have three available channels (one through three).

Balanced Audio Output Jack: XLR type connector 13. Unbalanced Audio Output Jack: 1/4" Phone Jack 14. Unbalanced Level Switch: “LOW” selection is for “Microphone-Level” output. “HIGH” selection is for “Line-Out” level output. 15. Squelch Adjustment: Adjust the squelch level to eliminate the RF noise interference at the receiver. 2.
2. AC/DC Power Connection: Fig. 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.
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. GND PIN 1 PIN 2 PIN 3 Fig.
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) Fig. 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).
Fig. 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. Fig. 7 Fig.
4. OPERATION INSTRUCTIONS 1. Turn the volume controls of the receiver and device in use to a minimum setting before turning on the microphone transmitter. After the receivers power switch is set to the on position, the power switch’s red indicator illuminates to denote normal power status. 2. If the SIGNAL LED indicators of the receiver are illuminated before switching on the microphone or transmitter, it indicates the receiver is receiving interference signals.
illuminate according to the strength of sound level. If the LEDs do not illuminate or sound is not present at the output, the system is not functioning properly and must be checked. 4. RECEIVER AND AMPLIFIER VOLUME ADJUSTMENT: a. Unbalanced Audio Output: Switch the level switch on the rear panel of the receiver to the left “LOW” Position, then adjust the volume control to twelve o’clock position. Adjust the volume control of the amplifier or mixer to an appropriate sound level.
d. If the receiver output level is adjusted to a level that is near the maximum input level of the desired device, it will cause saturation distortion of the device when the receiver output level is increased due to a increase in level by the sound source. Conversely, S/N ratio will decrease if the receiver volume control is adjusted too low. 5. Plug the cable of the mains unit into DC socket on the receiver’s back panel. Thread the cable through the cable grip as shown in the figure below (Figure 10).
SELECTING A FREQUENCY CHANNEL ON THE RECEIVER Your local dealer/distributor should be able to advise you on the best frequency selection for your area and help with selecting combinations of non interfering frequencies for multi channel installations. Interference is the most commonly reported “fault” with wireless microphone systems; we offer thirty channels from which to choose to help solve the problem.
HANDHELD WIRELESS MICROPHONE TRANSMITTER Like the receiver, the hand held microphone features advanced synthesized PLL design. It is preprogrammed with 30 user selectable frequencies and incorporates “Superior frequency tracking and muting techniques” dual squelch circuitry. The unique soft velvet rubber finish and overall balance of the microphone offers comfort and durability for the user.
on indicates that the battery is either dead or not installed. A constant glow indicates a weak batter that should be replaced. 5. On-Of switch. Push forward to turn the transmitter on and slide back to turn the transmitter off. RF signal is transmitted almost immediately the switch is turned on (and the corresponding RF present lamp will glow on the receiver), setting the receiver in to ‘stand by’ mode. AF signal is only transmitted when a RF link is active and the microphone threshold is opened, i.e.
2. BATTERY INSTALLATION 1. 2. Fig.12 Unscrew the grill/ball screen assembly at the collar to expose the battery compartment. 2. Insert the 9-volt battery taking care to observe the correct polarity. If the polarity is correct, the battery status indicator lamp will flash briefly. If no flash is observed, then it is likely the polarity is incorrect or the battery is dead flat and needs to be replaced. 3.
once audio is present. As mentioned previously, the level of these two indicators will indicate their signal strength at the receiver. When the microphone is not in use, please switch it off to conserve the battery BELT PACK TRANSMITTER 1 2 3 4 5 7 10 8 6 9 Figure 14 Like the receiver, the belt pack transmitter features advanced synthesized PLL design.

Group selector switch: make sure this setting matches the group selection on the receiver. 10. Channel selector switch: make sure this setting matches the channel selection on the receiver. 11. Battery compartment and cover: accepts one standard 9V battery.
3. Select a group/channel combination, making sure that it matches the combination already set on the receiver. 4. Connect your lapel microphone, guitar lead, or other input. Connection details are as per figure 15. 5. Adjust the gain control on the belt pack to the desired level.
