Active Noise Cancelling
The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call. Hear and be heard more clearly.
The M400BB has a built-in 10W amplifier that increases the audio output from an additional external speaker. The public address function allows you to make an announcement from the microphone like a loud speaker, and the foghorn can also be emitted from the external speaker.
When connected to an external GPS receiver, current position and time are shown on the COMMANDMIC™ display. When receiving DSC information from another vessel, the radio can transfer it to a navigational device via NMEA 0183 connectivity.
