The M45 is optimized for speech intelligibility and offers high sensitivity, a built-in preamplifier, immunity to RF interference, and is easy to install in a 1-1/2'' hole with no additional tools required. Microphone level signal and LED control are via an RJ45 connection. An adapter is included to convert from RJ45 to an 8-conductor plug-in terminal block. For use in Dante® networks, the AUDIX DN4 Enhanced Onramp for Dante AES67 is required, which supports up to four devices and includes logical LED control.'
