  • Description

    The M40 is a miniaturized condenser microphone with a fully integrated preamp designed with very high sensitivity for distance miking. The primary applications for the M40 include ceiling mounted video conferencing, distance learning, hospital rooms, surveillance, and ambient room miking. The M40 has complete immunity from RF interference caused by cell phones and GSM devices.

    The M40, which comes with a cardioid capsule, is also available with hypercardioid or shotgun capsules, allowing the microphone the ability to be used in a wide variety of applications. The M40 is easy to install requiring only that a 5/8 inch hole be drilled in the ceiling with no additional tools required. The cable assembly is equipped with a Phoenix connector. For installations where plenum rated cable is to be used, an optional nickel plated metal junction safety box is available.
