1. STACKING AND RACK MOUNTING RECEIVERS Multiple AXU4 receivers may be stacked or rack mounted as shown in Figure 9 Renee D l STACKED RECEIVERS FIGURE 9 RECEIVER MOUNTING RACK MOUNTED RECEIVERS To stack multiple receivers attach the rubber feet to the bottom corners of both units and make sure the bottom receiver is on a flat stable surface Extend antennas fully and point them away from each other at a 45 angle To rack mount one or two receivers slide the receiver s into a standard audio rack space Refer to the Optional Accessories paragraph for rack mount accessories If two receivers are mounted side by side the outer antennas should be at 45 and the inner antennas should be vertical WIRELESS SYSTEM OPERATION OPERATING YOUR WIRELESS SYSTEM 1 Slide the transmitter MUTE switch to the ON position 2 Sing speak or play your instrument at typical volume levels AXUGD systems turn the volume control on your guitar or bass all the way up Normal operation is indicated by Steady glow of one or both yellow DIVERSITY A B lights Flickering of the red TRANSMITTER AUDIO PEAK light when loud sounds are transmitted NOTE If the yellow DIVERSITY A B lights do not glow con sult the Troubleshooting Section in this guide If the red TRANSMITTER AUDIO PEAK light on the receiver does not flicker occasionally refer to the Wireless System Adjustmen2. unexpectedly sending loud bursts of noise through the receiver when the transmitted signal is weak or turned off Unlike conventional wireless systems Shure Access systems use a noise squelch circuit that analyzes signal quality instead of signal strength A special detector monitors the level of high frequency noise When the transmitter signal is strong the system s noise lev el is low and the receiver sends audio through When the transmit ter signal is weak or absent the system s noise level is high and the squelch circuit will mute the receiver This virtually eliminates the possibility of annoying bursts of noise coming through the receiver TIPS FOR ACHIEVING MAXIMUM PERFORMANCE Make sure you can always see a receiver antenna from the transmitter position Keep the distance from transmitter to receiver antenna as short as possible e Point receiver antennas away from each other at 45 from vertical Avoid placing the receiver antennas near metal surfaces and obstructions Monitor battery fuel gauge and replace battery as soon as red light is on Let the body pack transmitter antenna hang freely do not coil or keep in pocket f stacking or rack mounting receivers in a multiple system use situation do not allow antennas to touch or cross Perform a walk through before performance or presentation If dead spots are found adjust location of receiver If dead spots remain mark spots and avoid

Electronics counterclockwise English RECEIVER VOLUME ADJUSTMENT The volume control on the front panel of the AXU4 receiver can be adjusted to make the wireless system output level identical to that of a cabled guitar or bass or wired microphone After making any necessary transmitter gain adjustments adjust the receiver volume control until the output reaches the desired level Rotate the volume control clockwise to increase output Rotate it coun terclockwise to decrease output RECEIVER SQUELCH ADJUSTMENT The squelch control on the AXU4 receivers is factory preset for optimum performance No further adjustment is normal ly required It is possible to adjust the squelch control setting to emphasize either signal quality or system range Turning the squelch control clockwise causes the receiver to demand a higher quality signal less noise before mut ing but decreases operating range Turning the squelch control counterclockwise allows a low er quality signal through more noise before muting but in creases operating range To return the receiver squelch control to the factory setting ro tate it to the mid range position so the slot is vertical ABOUT THE SHURE NOISE SQUELCH SYSTEM Conventional squelch circuits analyze RF signal strength they cannot distinguish between noise and desired signals Conse quently when a conventional wireless system is used in a noisy RF environment its circuits may open
