Two rocker switches marked 'Interior' and 'Bullets'
separately turn on or off all the flybridge and aft deck speakers
or all the external Bullet pods by controlling the amplifiers.
Three remote level controls operate JL Audio line drivers
that in turn provide individual zone controls labeled 'aft',
'cockpit' (lower aft deck) and 'bow'. These remotely controlled
line drivers avoid long 'to' and 'from' audio cable runs.
Also, the line drivers provide considerably more line level
voltage than would otherwise be divided among 14 amplifier
inputs. The Clarion source unit fades between all flybridge
/lower aft deck speakers and all exterior bow and transom
speakers. We also utilized the Clarion's dedicated sub level
control.

 Three
JL Audio amplifiers provide a total of fourteen channels,
two of which are bridged to drive the subwoofer. The amplifiers
are attached to a custom mounting panel and concealed under
a seating console. Because of the conservative approach, which
maintains a 4-ohm load throughout most of the system, these
amplifiers barely get warm when run for long periods.

| Two pair of JL Audio 6½
-inch installed over the rear section of the flybridge
in order to surround the two captains' chairs. This provided
ambience and minimized the directional and localizing
effects of having speakers in such close proximity to
listeners.

At the rear of the flybridge a downfiring JL Audio
acoustic suspension 10-inch sub is loaded into a poly-coated
waterproof enclosure. Two louvered vents allow the bass
radiation to freely flow from the bench seat console.

|
|

 Fiberglass
mesh to the interior of the vents keep the bugs out. JL Audio
makes two marine subs. One is designed for a small sealed
enclosure while the other is intended for free-air or infinite
baffle applications.

To the front of the cockpit we used oversized 7.7-inch
coaxials to provide a little extra midbass since they
are more removed from the aft subwoofer.

JL Audio 'T' series 7.7-inch coaxials are optimized
for small pod displacement versus the free-air application
of the 'C' (cockpit) version. These oversized coaxials
are fitted into 8-inch diameter powdercoated spun aluminum
pods. The pods feature dual quick-release clamshell
brackets for easy removal and reinstallation. Quick-disconnect
waterproof deck plugs also make R&R convenient.
No tools are required.
These speakers do a great job of flooding the bow deck
with sound. Perfect for sun bathing or star gazing.
The individual zone controls are a must.

Two pair of JL Audio 'T' oversized 7.7-inch coaxials
project music over the swimdeck and out into the water.
They're perfect for relaxing on a raft or for swimmers.
Plus, these exterior speakers have their own zone control
allowing you to isolate, eliminate or blend in with
the rest of the system.

A DirecTV satellite receiver has high-definition
cable connections to the salon LCD TV, stateroom LCD, and
flybridge LCD plus a composite cable to the helm E-120 Raymarine
chartplotter. The Sat TV and salon DVD player use UHF digital
modulation for distribution to all TVs throughout the entire
boat. A radio frequency remote control for Sat TV adds wholeboat
control.
A high-isolation AB switch selects between the KVH TrackVision
in-motion antenna and a boathouse DirecTV antenna.

A concealed custom panel recesses an AC outlet,
antenna connection, HDMI jack and stereo RCA jacks. The RCAs
deliver the video soundtrack to the Clarion source unit for
complete audio impact on the flybridge.

A 32-inch LCD TV was added to the flybridge. A Sunbrella
protective cover will be added. The cover will be designed
to function as a safe carry and storage bag.
The LCD TV is removable. A powdercoated aluminum stanchion
fits into a console-mounted socket. A pin key keeps
the TV from freely rotating. A KingStarboard polymer
strikeplate protects the top of the powdercoated socket.
