The Shure MX690 Microflex is a tabletop transmitter equipped with a cardioid condenser boundary mic compatible with SLX4 and SLX4L receivers. The cardioid polar pattern focuses audio capture in front of the mic and rejects much of the off-axis ambient noise, great for picking up one speaker or allowing two panelists sitting next to each other to share a single mic.
Quick to set up and tear down, the MX690 offers a smart solution for conference and meeting spaces where wired mics are impractical and users demand flexibility with high performance. The unit's low profile is ideal for applications such as video-conferencing where minimum visibility is required.
The transmitter 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'. Run up to 12 mics per frequency band with a maximum of 42 mics in the room at the same time.
