SINGLE SYSTEM SETUP

RECEIVER CONNECTIONS

NOTE: If you are installing multiple ULXP4 Professional systems, or systems with multiple ULXP4 receiv-

ers, refer also to the Advanced Programming section of this manual.

1. Plug the dc power supply into the power connector on the back of the receiver, as shown in Figure 4. Connect the
other end of the power supply into an electrical outlet.

FIGURE 4

2. Attach the two antennas to the ANTENNA connectors, as shown in Figure 5. The ULXS4 is supplied with 1/4 wave
antennas; the ULXP4 is supplied with 1/2 wave antennas.

3. Connect audio cable(s) (not supplied) from the audio output(s) to the audio input(s) of your audio system, mixer and/or
amplifi er, as shown in Figure 6.

4. If the receiver XLR output is used, make sure the MIC/LINE switch setting matches the input requirements of the
mixer or amplifi er, as shown in Figure 7. The Mic/Line switch does not affect the output of the unbalanced 1/4 inch
phone jack.

TIPS FOR ACHIEVING OPTIMUM PERFORMANCE

Maintain a line of sight between the transmitter and receiver antennas. •
Avoid placing transmitter and receiver where metal or other dense materials may be present. •
Avoid placing the receiver near computers or other RF generating equipment such as CD players, DAT machines, and •

digital signal processors.
Avoid placing the receiver in the bottom of an equipment rack unless the antennas are remotely located. •
Point the receiver antenna tips away from each other at a 45° angle, and keep them away from large metal objects. •
Do not obstruct the receiver antennas. •
Use the proper cable when remotely locating receiver antennas. For best performance, use Shure UA825 or UA850 low •

loss coaxial antenna cable, or 50 ohm low loss cable such as RG-8U.
For remote antenna placement, use Shure UA820 1/2 Wave Antenna and UA830 Active Remote Antenna Kits, along •

with Shure UA844 Antenna Distribution System.
Mount diversity antennas at least 1/4 wave apart. This can be achieved by remote placement of one or both 1/2 wave •

antennas using Shure UA825, UA850, or UA8100 low loss coaxial cable and a Shure UA830 Active Remote Antenna
Kit in conjunction with a Shure Antenna Distribution System. For multiple system installations, use the Shure UA844
Antenna/Power Distribution System.

Try to maintain a distance of at least 5 meters (15 ft) between the transmitter and receiver. •

TURNING THE RECEIVER ON

NOTE: These instructions assume no other wireless microphone systems are in use.

CAUTION: DO NOT TURN ON THE TRANSMITTER BEFORE POWERING UP THE RECEIVER. TURNING

THE TRANSMITTER ON FIRST WILL INTERFERE WITH THE RECEIVER’S FREQUENCY SCAN­NING FUNCTION.

Turn the receiver on by pressing the power On/Off switch. The default Group 1 Channel 1 setting will appear on the receiver
display, as shown in Figure 8.

SCANNING FOR THE NEXT OPEN CHANNEL

1. To enter the Scan Mode, press the MODE button on the receiver once. SCAN CHANNEL will fl ash on the display,

as shown in Figure 9

.

2. Press the
nel number will appear on the display, as shown in Figure 10.

NOTE: If “NO” appears on the display, the receiver has not detected an open Channel in the current

Group. Change the Group according to the instructions on the following page. After changing the
Group, repeat Steps 1 and 2 above.

3. To tune the receiver to the new Channel, press the SET button. The display will return to the default mode, as shown
in Figure 11.

THE RECEIVER IS NOW READY TO USE.

UNLESS THE RECEIVER IS MOVED TO A DIFFERENT LOCATION, THIS PROCEDURE DOES

NOT NEED TO BE REPEATED. PROCEED TO TRANSMITTER SETUP SECTION.

CHANGING THE RECEIVER GROUP SETTING

1. Press the MODE button twice. The word GROUP will fl ash on the display, as shown in Figure 12.

FIGURE 12

2. Press the buttons (ULXS4) or rotate the control knob (ULXP4). The new frequency Group number will appear
on the display, as shown in Figure 13.

FIGURE 13

3. To tune the receiver to the new Group, press the SET button. The display will advance to the Change Channel mode.
Press the MODE button once more to return to the default mode.

NOTE: The receiver always defaults to the fi rst Channel in any new Group.

CHANGING THE RECEIVER CHANNEL SETTING

1. Press the MODE button three times. The word CHANNEL will fl ash on the display, as shown in Figure 14.

FIGURE 14

2. Press the buttons (ULXS4) or rotate the control knob (ULXP4). The new Channel number will appear on the
display, as shown in Figure 15.

3. To save the new Channel, press the SET button. The receiver will then return to the default mode.

ADJUSTING THE RECEIVER DISPLAY CONTRAST

1. Press the MODE button for two seconds. “LCD” will appear on the display, as shown in Figure 16.

FIGURE 16

2. Press the buttons (ULXS4) or rotate the control knob (ULXP4) to increase or decrease display contrast, as
shown in Figure 17.
