English SYSTEM FEATURES Shure LX Wireless Systems offer a number of exceptional features, including: • Exclusive Shure MARCAD Circuitry (LX4). MARCAD (MAximum Ratio Combining Audio Diversity) circuitry constantly monitors signals from both receiver sections and combines them to create a single output signal. The result is improved reception and exceptional freedom from dropouts. Half-Rack Receiver Size.

LX Wireless System RECEIVER MOUNTING SINGLE RACK-MOUNTED RECEIVER (FIGURE 6) If the receiver is to be located on a table or other horizontal surface, attach the four adhesive bumpers to the bottom corners of the receiver. If the receiver is to be mounted in an audio equipment rack, identify the rack-mount kits supplied with your system and follow the appropriate assembly directions below. 1. Remove two screws from each side of the receiver. 2.
English RECEIVER CONNECTIONS 1. Attach the supplied quarter-wave antenna(s) to the antenna connector(s) on the receiver back panel. For best performance, the LX4 receiver antennas should be oriented with the tips pointing away from each other at a 45° angle from vertical. The LX3 receiver antenna should be vertical. 2. 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. 3.

English CHECKING THE TRANSMITTER BATTERY Turn the transmitter PWR/OFF switch to the PWR position and observe that one or two of the three lights on the transmitter glows. The amount of battery life remaining will be indicated by the color of the light(s), as shown in the following table.
LX Wireless System ATTACHING THE LX1 TO A BELT OR GUITAR STRAP Attach the LX1 body-pack transmitter clip to a belt, waistband, or guitar strap by depressing the tab marked PRESS and slipping the belt or strap between the transmitter body and the belt clip, as shown in Figure 11. The clip holds tightest if the material is drawn to the clip's top wire (especially thinner guitar straps).

LX Wireless System OPERATING THE LX2 HAND-HELD SYSTEM LX2 TRANSMITTER RECEIVER LX2 HAND-HELD MICROPHONE SYSTEM OPERATION FIGURE 15 1. Slide the transmitter PWR/OFF switch to the PWR position. One of the three lights on the transmitter illuminates. 2. Press the POWER button on the receiver. The green power on indicator and the RF light(s) illuminates. 3. Slide the transmitter ON/MUTE switch to the ON position and begin speaking or playing your instrument.
English GAIN AND SQUELCH ADJUSTMENT ADJUSTING THE TRANSMITTER AUDIO GAIN LEVEL 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 the constant glow of the red light on the receiver audio level meter.
LX Wireless System ADJUSTING THE RECEIVER SQUELCH CONTROL The receiver squelch control is factory preset at the 12 o'clock position for optimum performance. No further adjustment is normally required. However, it is possible to adjust the squelch control to emphasize either signal quality or system range. • To raise the squelch threshold, rotate the control clockwise. This causes the receiver to demand a higher quality signal (less noise before muting), but it reduces the operating range.
English TROUBLESHOOTING 18 Problem Solution No sound; receiver RF light(s) and AUDIO lights not glowing. Make sure POWER switches on transmitter and receiver are on. Check transmitter Power/Battery Fuel Gauge to ensure that battery is providing power. Replace battery if necessary. Check receiver squelch setting. Check receiver antenna connection(s). Make sure at least one antenna is in the line of sight of the transmitter. If necessary, reduce the distance between transmitter and receiver.
