SINGLE SYSTEM SETUP 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.
4. If the receiver XLR output is used, make sure the MIC/LINE switch setting matches the input requirements of the mixer or amplifier, as shown in Figure 7. The Mic/Line switch does not affect the ouput of the unbalanced 1/4 inch phone jack. LINE MIC 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.
Changing the Group 1. Press the MODE button twice. The word GROUP will flash on the display, as shown in Figure 12. FIGURE 12 2. Press the or 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.

TRANSMITTER SETUP Transmitter Battery Installation Open the battery cover and insert a fresh 9V alkaline or lithium battery, as shown in Figure 20. + + – – FIGURE 20 ULX1 Bodypack Connections If you are using a Bodypack system with a Shure lavalier microphone or instrument adapter, plug the microphone cable or instrument adapter cable into the transmitter input connector, as shown in Figure 21. NOTE: The wiring of the input connector on the transmitter is designed for Shure microphones.
Checking Transmitter Battery Power With the transmitter turned on, observe the Battery Level icon on the display. The number of shaded bars on the icon indicate the approximate amount of battery life remaining, as shown in Figure 23. NOTE: Stated battery life is based on a 9V Duracell alkaline battery. For details on other battery types, refer to the “Battery Life” paragraph, or go to the Shure web site at www.shure.com and refer to the FAQ section.
4. To change the transmitter Channel number so that it matches the Channel number on the receiver display, press the SET button to advance to the desired Channel number, as shown in Figure 27. FIGURE 27 5. Press the MODE button again to select the new Channel setting. “FrCh” will appear briefly on the display, indicating that the frequency has changed. Then the new Group and Channel settings will appear. Refer to Figure 28. FIGURE 28 6.
SYSTEM OPERATION Speak into the microphone or play your instrument. Assuming your audio system is properly set and functioning, you should hear the sound of your voice or instrument coming through the loudspeakers. The RF and Audio LEDs on the receiver should also illuminate. Refer to Figure 30. FIGURE 30 Transmitter Gain Adjustment If necessary, adjust the transmitter gain until only the yellow LEDs on the receiver light up as you speak into the microphone or play your instrument.
Locking Transmitter Frequency Settings 1. 2. 3. Slide the power switch to the OFF position and wait for the display light to turn off. Hold down the SET button. Slide the power switch back to the ON position. “Fr L” will appear on the transmitter display, indicating that the frequency setting is locked. The locked frequency Group and Channel will then appear. See Figure 32. 1 1 2 2 ULX1 ULX2 FIGURE 32 Unlocking Transmitter Frequency Settings 1. 2. 3.
Unlocking Power On/Off Switch 1. 2. Verify that the power ON/OFF switch is in the ON position. While holding down the SET button, press and hold the MODE button until “Po UL” appears on the display.See Figure 35. This display indicates that the Power On/Off switch is unlocked. The transmitter will then return to normal operating mode. 1 2 3 ULX1 1 2 3 ULX2 FIGURE 35 ADVANCED PROGRAMMING MODE (ULXP4 MODELS ONLY) Scanning Frequency Groups 1. Hold down the SET button and press the MODE button once.
Adjusting the Receiver Squelch Setting The receiver squelch control is factory preset for optimum performance. Normally, no further adjustment is required. However, it is possible to adjust the squelch control to improve either signal quality or increase system range. NOTE: Increasing the Squelch level causes the receiver to demand a higher quality signal (less noise before muting), but it reduces operating range.
NOTE: If the volume control knob has been set to a level higher than the locked level, the output level will remain locked and the Volume Level warning indicator will flash on the receiver display. See Figure 45. Rotate the volume control knob counterclockwise until the Volume Level warning indicator stops flashing. This will unlock the output level setting.
Rack Mounting Dual ULXP4 Receivers 1. 2. Align the receivers side by side so that the front panels both face the same direction. Place the supplied straddle bars in the recesses on the top and bottom of the receivers, so that the bars overlap both receivers. Refer to Figure 49. Ñ ÑÑÑ ÑÑÑÑÑÑÑ ÑÑÑ Ñ ÑÑÑ ÑÑÑ Ñ ÑÑÑÑÑÑÑ Ñ ÑÑÑ ÑÑÑ Ñ ÑÑÑ FIGURE 49 3. 4. 5. Secure the straddle bars to the receivers using the supplied screws. Refer to Figure 50. CAUTION: Do not overtighten the screws.
TIPS FOR ACHIEVING OPTIMUM PERFORMANCE S Maintain a line of sight between the transmitter and receiver antennas. S Avoid placing transmitter and receiver where metal or other dense materials may be present. S Avoid placing the receiver near computers or other RF generating equipment such as CD players, DAT machines, and digital signal processors. S S S S Avoid placing the receiver in the bottom of an equipment rack unless the antennas are remotely located.
