INTRODUCTION

The MX692 wireless boundary microphone is for use in a variety of boardroom, education,
government, and house of worship applications that require a clean, cable-free installation. Ad­ditionally, the MX692 is useful in retrofit installations where the modification of existing architec­ture and furnishings is unwelcome, and in facilities where a flexible, mobile audio system is
required.

The user-programmable mute switch and interchangeable microphone cartridges allow cus­tomization of microphone behavior and audio response to suit many applications. The transmit­ter antenna is mounted internally, giving the microphone a sleek appearance.

The MX692 integrates a boundary microphone and a wireless transmitter. The transmitter
broadcasts on the UA (782.125–805.750 MHz) and UB (692.500–715.625 MHz) frequency
bands. These frequencies are legal for broadcast in the U.S., Canada, Central and South Amer­ica, and Australia.

The Shure UC Wireless system divides frequency bands into “groups” and “channels.” Up to
sixteen individual MX692 transmitter/UC4 receiver pairs, each with its own channel, may be as­signed to a single group. With two frequency bands to choose from, it is possible to run up to 32
microphones simultaneously in a single sound system.
