ENGLISH SYSTEM DESCRIPTION The Shure UHF Wireless microphone system is a frequency-agile diversity system operating in the UHF band. Both the receiver and the transmitter are synthesizer controlled via Phase Locked Loop (PLL) circuitry for clear, steady radio frequency (RF) signal. The receiver is available in either dual or single models that fit into a standard 19 inch (482 mm) equipment rack. An auxiliary unswitched AC output jack allows multiple receivers to be linked “daisy chain” style.

ENGLISH RECEIVER SETUP Installing Rear Mounted Receiver Antennas Attach the supplied UHF antennas to the antenna BNC connectors on the receiver back panel, as shown in Figure 5. For best performance, orient the antennas with tips pointing away from each other at a 45° angle from vertical. FIGURE 5 Installing Front Mounted Receiver Antennas 1. Insert the two bulkhead adapters through the larger holes on each side of the front panel, and secure them from each side, using the supplied attaching hardware.
ENGLISH 2. Connect the supplied antenna cables to the receiver and the bulkhead adapters, as shown in Figure 7.

Once the receiver is in the rack, it is more difficult to insert the bulkhead adapters and connect the antenna cables. 3.
ENGLISH Basic Receiver Connections (Figure 10) 1. Connect the receiver output to the mixer or amplifier input, using a standard audio cable with a female 3-pin XLR connector or 1/4-inch phone plug. 2. If desired, plug a set of headphones into the headphone monitor output connector.
ENGLISH 3. Connect the female end of a modular power cord to the male power input connector on the rear panel of the receiver. Then plug the power cord into a suitable AC power source. NOTE: If the receiver is rack-mounted, or if using front–mounted antennas, the antennas should extend above the rack cabinet or be remotely located. Improved diversity performance may be obtained by installing one or both antennas at a remote location and separating them by 1.5 meters (60 inches) or more.
ENGLISH 4. Press the “SELECT” button to choose Group or Channel. The current Group, Channel, and TV channel setting appears, as shown in Figure 13.

Press the – button to make more changes, or press + to save the new squelch setting and return to the Group/Channel/TV display. FIGURE 28 NOTE: If more than 20 seconds of inactivity elapse, the display returns to the original settings. Locking the Receiver Display 1. Press the MENU button. The “+ MENU –” display appears, as shown in Figure 29. FIGURE 29 2.
ENGLISH 3. Press the SELECT button. The “CODE?” display appears, as shown in Figure 31. FIGURE 31 4. Press +, –, +, in that order, to engage the display lock. The display shown in Figure 32 appears. FIGURE 32 NOTE: Write down the lock code (+, –, +) and keep it in a secure place. If no code is entered, the system times out and return to the main display. 5. A small “lock” symbol appears in the upper right corner of the status screen displays, as shown in Figure 33.
ENGLISH TRANSMITTER SETUP Transmitter Battery Installation (Figure 34) 1. Make sure the transmitter power ON/OFF switch is in the OFF position. 2. Open the transmitter battery compartment as follows: • U1 Transmitter: Squeeze the two tabs on either side of the transmitter and flip the battery cover down. • U2 Transmitter: Unscrew the battery cover and slide it down. 1.5V AA 1.5V AA 1.5V AA 1.5V AA FIGURE 34 3.
ENGLISH Checking Transmitter Batteries (Figure 35) 1. Turn the transmitter power ON/OFF switch to the ON position. 2. Observe the battery fuel gauge displayed on the transmitter screen and on the right side of the receiver screen. The number of black segments displayed indicates battery power level. As transmitter batteries are consumed, the displayed segments will gradually disappear.
ENGLISH Connecting a Lavalier Microphone or Instrument Cable to the U1 Transmitter (Figure 36) 1. Plug the microphone cable or instrument cable into the transmitter input connector. 2. Attach the lavalier microphone to your tie, shirt, or collar. If using a headset, put the headset on. 3. If using an instrument adapter cable, attach the other end of cable to the instrument output connector.
ENGLISH 3. Press and hold down the MODE button until only the Group number displays, as shown in Figure 38. FIGURE 38 4. Press the SET button to increment the Group setting, as shown in Figure 39. FIGURE 39 NOTE: If the SET button is held for more than 5 seconds, the display goes into the fast increment mode. If more than 20 seconds of inactivity elapse, the display returns to the original settings.
ENGLISH 5. Press the MODE button again so that only the Channel number displays, as shown in Figure 40. FIGURE 40 6. Press the SET button to change the Channel setting, as shown in Figure 41. FIGURE 41 7. Press the MODE button again so that the new Group and Channel numbers both display. NOTE: On transmitter, the transmitter operating frequency does not change until new settings are saved.
ENGLISH Locking the Power Switch in the ON Position To lock the power switch, press and hold the SET button, then press and hold the MODE button. Hold both keys down until “PoL” (for power locked) displays, as shown in Figure 42. FIGURE 42 NOTE: When the Power On Lock function is activated, “–– ––” will flash on the transmitter screen every 5 seconds when the transmitter power ON/OFF switch is in the OFF position.
ENGLISH Activating the Frequency Lock Function The Frequency Lock function prevents accidental frequency changes, and is particularly useful in preventing accidental or unauthorized changes. The lock function is retained in memory, even if the transmitter is turned off and the batteries removed. To activate the Frequency Lock function, proceed as follows: 1. Turn the transmitter power off. 2. Turn the power back on while holding down the SET button until the fuel gauge on the transmitter is active.
ENGLISH NOTE: When the Frequency Lock function is engaged, the Power On Lock function can still be activated. However, if the Power Lock and the Frequency Lock functions are engaged, the Power Lock function must be disengaged before cancelling the Frequency Lock. Cancelling the Frequency Lock Function (Figure 46) To cancel the Frequency Change Lock function, repeat the steps in the preceding Activating the Frequency Lock Function paragraph.
ENGLISH 5. Turn the receiver on by pressing the upper section of the POWER switch. The receiver display and RF LEDs glows. 6. Make sure the transmitter and receiver are tuned to the same Group, Channel, and Frequency. If necessary, change the settings on either the transmitter or receiver. 7. If using a headphone monitor, push the monitor knob on the receiver (U4S) or half the way down (U4D). The headphone monitor light, located below the knob, glows.
ENGLISH ADJUSTING TRANSMITTER AUDIO GAIN LEVEL (FIGURE 47) The transmitter audio gain level has been factory pre-set to provide satisfactory output in most applications. However, for loud singers or high-output musical instruments, the preset level may be too high, as indicated by constant glow of the red audio level LED. Soft-spoken talkers or singers may find that the factory setting is too low, as indicated by the failure of the amber audio level LED to glow at all.
ENGLISH ADJUSTING TRANSMITTER AUDIO INPUT LEVEL (FIGURE 48) NOTE: The factory-preset (–6 dB) should match most applications. Before changing the audio input level, try adjusting the transmitter gain (see Figure 47). The U1 body-pack transmitter has an attenuator switch allowing you to set the audio input level for different types of applications.
ENGLISH TIPS FOR ACHIEVING OPTIMUM PERFORMANCE S 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. S Avoid placing the receiver near computers or other RF generating equipment. S Avoid placing the receiver in the bottom of an equipment rack unless the antennas are remotely located. S Use the proper receiver antennas.
ENGLISH Problem Solution No receiver sound; RF and Audio Level meter LEDs glowing. Turn up the receiver audio output Level control. Check for proper connection between receiver and microphone mixer. Talk into the microphone and observe the receiver audio level LEDs. If they glow, the problem is elsewhere in the sound system. Received signal is noisy or contains extraneous sounds with transmitter on. Check transmitter Power/Battery Fuel Gauge and replace battery if power is low.
ENGLISH APPENDIX: NETWORK INTERFACE PIN MAP The U4S and U4D receivers both have a 25–pin network interface located on the rear panel. The interface allows future monitoring and control of all receiver functions, including audio level, RF level, and “A/B” diversity indication, from a remote location via an interface device. The table below identifies the signal output by each pin on the connector. Contact you Shure dealer for addition information.
