All control and audio for the radio and electronic equipment is handled by an interface box below decks in the rear just under the captains seat.  This interface also handles the AC power distribution and switching for the inbuilt 25 Amp battery charger, and AC inverter.

Interface controller box shown.  The six molex connectors are 24 pins each, most of which route to and from the turret on the helm console.  Two additional connectors are for future use.  The two RCA phono jacks route the left and right channel stereo audio to the low power 100 milliwatt broadcast transmitter on board.   The four orange AC connections bring power into the interface for battery charger switching, and AC inverter control and distribution.  All wiring is tagged and documented for maintenance and future expansion.  To the left is the 25 AMP battery charger that charges the batteries when connected to shore power at the dock.
