Modeled after the popular MX392 boundary microphone, the MX692 maintains the MX392s sleek profile, modern design, and ease of customization. In addition, the MX692 includes a built-in Shure UC wireless transmitter, allowing freedom of microphone placement and movement. Drilling wire exit holes in desks and tabletops is a thing of the past. With the flexibility to move from room-to-room and system-to-system, the MX692 increases the effectiveness of most any boardroom, classroom, or other sound installation.

Use the 0dB position for nor-
mal voices. Use the -20dB position for loud voices. Transmitter Output Gain Control Changes the audio level to accommodate various input volumes. Use the supplied screwdriver
(Xcelite R3322 or equivalent) to make adjustments. Channel Setting Control Rotating the Channel dial changes the Channel setting. Use the supplied screwdriver (Xcelite R3322 or equivalent) to make adjustments. Group Setting Control Rotating the Group dial changes the Group setting. Use the supplied screwdriver (Xcelite R3322 or equivalent) to make adjustments. English 6 REPLACING THE BATTERY To access the battery compartment, as well as the internal gain and channel settings, turn the microphone over. Unlatch and open the battery compartment door. To remove the battery, simply lift up on the edge opposite the contact points. English 7 ADJUSTING THE TRANSMITTER GAIN LEVEL The transmitter audio gain level has been factory preset to the mid position. For optimal perfor-
mance, adjust the audio gain control on the bottom of the transmitter so that the audio LED meter on the receiver regularly reaches amber and will momentarily flash red during the loudest sounds. CHANGING THE TRANSMITTER GROUP/CHANNEL SETTINGS 1. Turn the transmitter off and open the battery compartment to expose the GROUP and CHANNEL switches. 2. Using the supplied screwdriver, rotate the GROUP switch until the desired setting is reached. Then rotate the CHANNEL switch until the desired setting is reached. IMPORTANT: Use a single group and successive channels when setting frequencies. Transmitter GROUP and CHANNEL settings must match receiver GROUP and CHANNEL settings. English 8 NOTES ON MICROPHONE USE This wireless microphone operates from 782806 MHz (UA) and from 692716 (UB) frequencies. These broadcast frequencies may be used exclusively in Canada, the U.S., Mexico, all Central and South American countries, and Australia. Do not use the MX692 microphone on metal surfaces. Do not place laptop computers, open or closed, in front of the microphone during use. When using multiple wireless systems, use a single group and successive channels. This will avoid interference between systems. The MX692 wireless microphone/transmitter uses the Shure UC4 wireless receiver. English 9 POSITIONING THE MICROPHONE With the standard cardioid cartridge installed, the MX692 will pick up audio at conversational volume levels within 1.5 M (5 ft.) in a 130 degree radius. As a general rule for tables with multiple seats, a single microphone should be used for every two people speaking. 130
< 1.5M (5 FT.) English 10 POSITIONING MULTIPLE MICROPHONES In any installation, good vocal amplification can be achieved by following the positioning rules on page 10. For information on receiver setup and positioning, see your UC4 Wireless System user guide. English 11 POSITIONING YOUR RECEIVER
>3 M (10 ft.)
<15 M (50 ft.) MX692 UC4 72 The receiver may be wall-mounted or used in conjunction with a remote antenna system, such as the Shure UA500. The distance between transmitter and antenna should never be greater than 15 meters (50 feet) or less than 3 meters (10 feet). See your UC4 user manual for additional information on receiver and system setup. English 12 REMOVING THE GRILLE 1. Open the battery compartment 2. Remove the battery 3. Loosen and remove the screw at the base of the battery compartment 5. Insert the screwdriver into the opening above the battery compartment 4. Remove the retainer 6. Press gently on the underside of the microphone grille with the tip of the screwdriver until the grille pops out English 13 ADDITIONAL OR REPLACEMENT CARTRIDGES Additional or replacement cartridges may be purchased for the MX692. For more information or to order cartridges, contact the Shure service department or an authorized Shure service center. Omnidirectional Cartridge ............................................R183 Supercardioid Cartridge ...............................................R184 Cardioid Cartridge ........................................................R185 To replace the microphone cartridge:
1. Remove the grille (see page 13) 2. Loosen the screw and remove the cartridge clamp 3. Turn and remove the existing cartridge 4. Reverse procedure to install new cartridge English 14 THE INTERNAL DIP SWITCHES The behavior of the touch-sensitive switch on the microphones front panel (see page 5) can be customized using the internal DIP switches. See page 16 for customization options.

Make sure both the transmitter and the receiver are turned on Check the MX692 battery gauge, and replace the battery if necessary Make sure the transmitter and receiver frequency group/channel settings are identical Make sure there is an unobstructed line-of-sight between the transmitter and receiver If necessary, reposition the receiver, or decrease the distance between transmitter and receiver Remove local sources of RF interference, such as lighting equipment For in-depth troubleshooting, see your UC Wireless System user guide.
