Shure MX690-G4

Wireless Boundary Microphone

The Shure MX690-G4 is a frequency-agile wireless boundary microphone operating in the G4 (470–494 MHz) UHF band. Designed for boardrooms and conference spaces where wired microphones are impractical, it features an internal transmitter that sends audio to a receiver without the need for drilled cables.

This tabletop transmitter includes a cardioid condenser boundary microphone compatible with SLX4 and SLX4L receivers. The cardioid polar pattern captures audio directly in front of the microphone and rejects much of the off-axis ambient noise. It is great for one or two speakers sitting close together. 

The MX690-G4 ensures reliable transmission and high-quality audio, along with easy installation. It provides up to 8 hours of operation on two AA batteries, with a fixed 30mW RF power output and a transmission range up to 100'.
