The BG-EXM-SM5 is an expansion microphone that extends the pickup range of the BG-SMB-5M speakerphone. Featuring 360 degrees of audio pickup, the maximum range of the BG-SMB-5M can be extended up to 33 feet when combined with the BG-EXM-SM5. Up to two of these extension mics can be connected directly into the host microphone.


The BG-EXM-SM5 expansion microphone connects to one of the two RJ11 ports on the BG-SMB-5M. This unit benefits from the main unit’s full-duplex echo cancellation to eliminate the feedback commonly experienced when using the built-in microphones on most laptops. In addition to echo cancellation, this unit also utilizes noise reduction and a proprietary wideband HD voice enhancement algorithm to provide high-quality audio in any environment. The expansion microphones are equipped with a mute button and red/green status indicator.
