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. 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.

microphone over. Unlatch and open the battery compartment door.
To remove the battery, simply lift up on the edge opposite the contact points.
English – 8
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.

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.
This will avoid interference between systems.
• The MX692 wireless microphone/transmitter uses the Shure UC4 wireless receiver.
English – 10
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.
< 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.
English – 12
POSITIONING YOUR RECEIVER
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.

TROUBLESHOOTING
If your system is properly configured and you are having troubles, check the following:
• 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.
