Motivator’s PO
(previous owner) installed the above LCD television and a surround sound system
with a VHS tape/DVD player. As a friend
said, the only VHS tape we have left is our wedding video. Besides being dated, the LCD TV and 110 volt Panasonic
entertainment system was an ASD (amp sucking dog).
The first thing to go was the LCD TV in favor of a Samsung
LED TV. Power consumption of LED TV’s is
much less, and they do not produce the heat that LCD’s produce.
Finding a replacement for the
Panasonic entertaiment system was more of a challenge because the PO had cut a
hole in the cabintry for the install. We
finally decided on a Pioneer DVD receiver that are normally used in vans to
entertain the rug rats in the rear seats.
While the receiver has a small touch screen, we mainly were interested
in the available component connections on the back and that it is a 12 volt
system. Unfortunately, the superior HDMI
connections are not availible on vehicle units yet, so the connection to the TV
was via AV cables.
The DVD/receiver was connected to the PO’s interior speakers
that were still in good shape unlike the non-marine grade speakers that were
used on the rear deck.
New marine grade speakers were added on the rear deck and
connected via a 12 volt pre amp to the DVD/receiver. The old system could drive the deck speakers
without a pre amp, but we found it cumbersome to operate and occasionally found
that we were letting the rest of the marina listen to the sound track to Lethal Weapon II.
Because we were adding more 12 volt components a dedicated
fuse box was added for the entertainment system. This allowed for the correct amperage fuse to
protect each component.
One piece of entertainment kit that we have really enjoyed
is a Western Digital Live TV Hub with a 1 TB hard drive. The Hub allows us to load our favorite
movies, song and pictures to the drive for playback. Because it also connects to the Internet it
allows streaming of venues like YouTube.
We watched the Presidential debates and some of the America’s Cup via
live streaming.
The Hub is connected to the TV via a HDMI, however we are
now getting more HDMI components than available inputs on the TV, so a HDMI
selector was added to the system. The
Hub initially was a 110 volt component, but like many items it can be converted
to 12 volts by simply cutting off the transformer on the power cord and
connecting to a 12 volt supply.
A Blu-ray disk player was added to the system because
occasionally we can only find certain movies in Blu-ray format, and the vehicle
receivers do not support Blu-ray, yet.
Plus, because of the hole cut by the PO in the cabinetry, we have room
to fill.
We now have three 110 volt components that need to be
powered. This is not a problem when we
are on shore power or have a generator running, but we want it to be efficient
when we are quietly sitting at anchor.
Motivator’s 2500 watt
inverter/charger can easily handle the entertainment components, but not as
efficient as a smaller dedicated inverter.
But, if the 110 volt power strip is connected directly to the dedicated
inverter, the system will be drawing on the batteries needlessly when on shore
power or one of the generators is running.
An AC/DC transfer switch solves this problem. The one we used is from KISAE
Technology. Besides automatically selecting
the power source it transfers rapidly enough that we barely get a blink when
switching from generator to batteries.
Previously we had to shutdown the Hub or DVD player prior to switching
over.
Because we want the system to be networked, an Ethernet hub
was added and connected to Motivator’s LAN.
(Note: not shown are satellite
TV and iPod connections)
One more component can’t hurt, so a 1 TB Network Accessible
Storage (NAS) was also added for additional storage and computer backup.
The original hole cut by the PO for the Panasonic system was
trimmed out and a flip up black Plexiglas door was fabricated to cover the
components and switches.
On the back side, inside the cabinet, a facing was added to
hide all of the cabling sins while providing access to components that
occasionally need attention. A switch with
a LED light for the rear deck speaker’s pre amp gives us visual assurance that
we are not sharing Lethal Weapon II with
the rest of the marina.
But, what’s the”Parking Brake?” Pioneer and all manufactures of vehicle video
devices want to ensure that the driver is not watching a movie while
driving. So, the unit is designed to be
connected to the parking brake switch so that video is only available when the
parking brake is engaged. I contacted
Pioneer and explained that my parking brake is called an anchor, but they
advised that there was no way around this “safety feature.”
