Receiver Connections
NOTE: If you are installing multiple ULXP4 Professional systems, or systems with multiple ULXP4 receivers,
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.
FIGURE 5
3. Connect audio cable(s) (not supplied) from the audio output(s) to the audio input(s) of your audio system, mixer and/
or amplier, as shown in Figure 6.
FIGURE 6

4. If the receiver XLR output is used, make sure the MIC/LINE switch setting matches the input requirements of the
MIC LINE
mixer or amplier, as shown in Figure 7. The Mic/Line switch does not affect the output of the unbalanced 1/4 inch
phone jack.
FIGURE 7
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.
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 ash on the dis-
play, as shown in Figure 9.
FIGURE 9
2. Press the or buttons (ULXS4) or rotate the control knob (ULXP4) clockwise one quarter turn. The next open Channel
number will appear on the display, as shown in Figure 10.
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.
