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 output of the unbalanced 1/4 inch phone jack. MIC LINE 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 Receiver Group Setting 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 1. Open the battery cover and insert a fresh 9V alkaline or lithium battery, as shown in Figure 20. FIGURE 20 ULX1 Bodypack Connections 1. 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 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. Press the SET button to advance to the desired Channel number, as shown in Figure 27. FIGURE 27 5. To reverse the direction of the Group or Channel search, hold down the SET button and press the MODE button. See Figure 28. FIGURE 28 6. 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 29. FIGURE 29 7.
SYSTEM OPERATION Speak into the microphone or play your instrument. If your audio system is properly set and functioning, you should hear the sound of your voice or instrument coming through the loudspeakers. The LEDs on the receiver should also illuminate. The top TX AUDIO LED is red and should only illuminate momentarily when you speak loudly or play your instrument loudly. Refer to Figure 31.
Locking Transmitter Frequency Settings 1. Refer to Figure 33. Slide the transmitter power switch to the OFF position and wait for the display light to turn off. 2. Hold down the SET button. 3. 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. ULX1 1 ULX2 3 2 2 1 4 3 5 4 5 FIGURE 33 Unlocking Transmitter Frequency Settings 1.
Locking the Power On/Off Switch 1. Turn the transmitter on by sliding the power switch to the ON position. 2. While holding down the SET button, press and hold the MODE button for four seconds. “Po L” will appear on the display. See Figure 35. This display indicates that the Power On/Off switch is locked. The transmitter will remain on, even when the power ON/OFF switch is moved to the OFF position. NOTE: Make sure both buttons are depressed when trying to lock the transmitter.
ADVANCED PROGRAMMING MODE (ULXP4 MODELS ONLY) Scanning Frequency Groups 1. Hold down the receiver SET button and press the MODE button once. The words GROUP and SCAN will flash on the display. Refer to Figure 37. FIGURE 37 2. To begin scanning, rotate the control knob one quarter turn clockwise, as shown in Figure 38. The receiver will automatically begin scanning each Channel in all Groups. This may take up to two minutes, and the word “BUSY” will appear on the display. FIGURE 38 3.
2. Rotate the control knob. The new Squelch setting will appear on the display, as shown in Figure 42. 3. To accept the new Squelch value, press the SET button. The display will then return to the Default Mode, press FIGURE 42 the MODE button again. Locking the Receiver You can lock the ULXP4 receiver frequency and output level to prevent unauthorized or accidental changes to the settings. To access the Lock functions, proceed as follows: 1.
RECEIVER INSTALLATION Table Mounting the ULXS4 Standard Receiver To mount a ULXS4 Standard receiver on a table or other horizontal surface, attach the four adhesive bumpers to the bottom corners of the receiver and place the receiver on the mounting surface. See Figure 47. FIGURE 48 NOTE: The ULXS4 can also be rack mounted, using one of the Rack Mount Kits listed on page 24. Rack Mounting a ULXP4 Professional Receiver 1.
Rack Mounting Dual ULXP4 Receivers 1. Align the receivers side by side so that the front panels both face the same direction. 2. 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 50. 1/4 IN. FIGURE 51 3. Secure the straddle bars to the receivers using the supplied screws. CAUTION: Do not overtighten the screws. Doing so may damage the printed circuit boards. 4.
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.

NOTE: Batteries stored for more than a year or stored in excessively hot environments may experience a higher failure rate. NOTE: When using rechargeable batteries, do not use any battery with a fully-charged rating of greater than 9v, for example, 9.6V ULX Transmitters use a DC-to-DC converter, which require a minimum 6 V to operate. It the battery does not provide this threshold voltage, the transmitter will not operate.
INDICATOR STATUS PROBLEM RECEIVER ULXS4 ULX4P SOLUTIONS TRANSMITTER ULX1 ULX2 Sound level from the receiver is different from that of a cabled guitar or microphone. • • Adjust transmitter gain as necessary. Adjust receiver volume as necessary. Sound level is different when you change guitars. • Adjust transmitter gain to compensate for differences when you change between guitar output levels. Distortion increases gradually. • Replace transmitter battery.
