Not just a simple radio interface. We use the latest electronic technology to enabled us to produce an efficient powered radio interface, with very low power consumption typically only 6mA , and all the features a pilot would require.The user can change various selectable features which reconfigure radio type (i.e. from type'A pcom A20] to Type 'BB' [lcom A6]) etc, control intercom volume levels, mute audio levels, etc.
The Microavionics Interface Power Lead is used for connecting external power supply to radio interface. Used with a powered radio interface. Note external power is not required to power interface but using the external power the interface will trickle charge the headsets and power a VHF radio.
