INTRODUCTION The Shure MX692 Microphone and Wireless Transmitter brings the flexibility and ease of wireless microphone use to the well-established Microflex line of installed-sound microphones. Modeled after the popular MX392 boundary microphone, the MX692 maintains the MX392’s 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.

GAIN AND CHANNEL SETTINGS To access gain and channel settings, open the battery compartment (see page 7). 1 Input Attenuation Control This two position switch lets you select either 0 dB or -20 dB attenuation, depending on the volume of the speaker’s voice. Use the 0dB position for normal voices. Use the -20dB position for loud voices. 3 901 01 AB CD 2 Changes the audio level to accommodate various input volumes. Use the supplied screwdriver (Xcelite R3322 or equivalent) to make adjustments.
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.
ADJUSTING THE TRANSMITTER GAIN LEVEL The transmitter audio gain level has been factory preset to the mid position. For optimal performance, 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.
NOTES ON MICROPHONE USE • • • • • This wireless microphone operates from 782–806 MHz (UA) and from 692–716 (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.
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.
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.
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.
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 4. Remove the retainer 5. Insert the screwdriver into the opening above the battery compartment 6.
