Sea Ray 420 DA Hardtop

This Sea Ray 420 Sundancer boasts a full compliment of audio and video entertainment amenities.

We installed a 27-inch TV in the slip. The slip’s TV accesses the satellite TV receiver which is located in the boat. The single ship-to-shore antenna run carries both the input to the Sat TV receiver and its output.
 

 The commercial-grade mounting bracket was supplemented with aluminum ‘L’ brackets and stainless steel hardware to keep this heavy TV secure. Also, a Sunbrella cover will protect the TV from harsh weather.
The boathouse DirecTV antenna and galvanized steel extension to clear the roof. 

A watertight non-metallic enclosure provides a serviceable ship-to-shore link and gives protection to electronic components.


In order to install a KVH TracVision, a custom built tower was needed to adapt to a sloping hardtop. The KVH is elevated to clear any obstruction from the open-array radar scanner. A forward one degree lean is maintained to match the radar mounting pad. Also, as part of the tower design, connecting cables are concealed and routed into the hardtop’s internal raceways.

EXTERIOR AUDIO AND VIDEO

We installed a 20-inch LCD TV on the cockpit. A custom powder-coated aluminum mount features a quick-release bracket making safe storage easy.

The LCD is viewable from the captain’s chair to the bench seat along the transom. Everybody gets a view.

A digital remote control at the helm and one on the transom.

Also, radio frequency remote controls add convenience from the bow deck, slip or in the salon when using the theater sound. In this case two RF fobs are coded into the RF receiver.

A 7-band equalizer delivers six output channels of 7-volts. This is an effective line driver to maintain a high dynamic range when splitting the signal among ten channels of cockpit amplification.

Zone controls include a.) fade from cockpit interior speakers to exterior speakers, b.) subwoofer level control, c.) dedicated transom speakers level control, and d.) dedicated bow speakers level control.

The three cockpit audio system amplifiers are mounted behind the salon couch.


We upgraded the factory speakers to MB Quart marine oversized integrals. These speakers have bridge mounted titanium tweeters that can be rotated to compensate for their position.
Port and starboard speakers at the helm.

Port and starboard speakers high in the arch/hardtop with the tweeters aimed forward toward the helm.
Here is Port starboard speakers in the combing at the aft deck. A special flushmount trimring and concealed baffle provide ideal speaker acoustical placement while allowing the motorized deck to clear.

White powder-coated spun-aluminum enclosures house MB Quart speakers. White polymer mounting flanges are contoured to fit the curved surface of the hardtop interior as well as level the speakers against an angled surface. These speakers are intended to project out over the slip or out to those afloat on rafts or tubes behind the swim deck.

 

The bow deck pads provide for comfort when sunbathing, stargazing or just using the bow deck as a remote location for conversation. A pair of Boston Acoustics Voyagers deliver music from their removable bow rail mounts.

Two downward louvered vents allow the subwoofer radiation to flow freely.

Within the rear cockpit seating console a downfiring 10-inch subwoofer is mounted in a waterproof polyurethane enclosure.

At the helm a second 10-inch subwoofer ensures an even level of bass throughout this sprawling cockpit.

CABIN AUDIO VIDEO

Over the galley and facing the salon a motorized lift reveals or conceals a 20-inch LCD.


Permanently concealed within a galley cabinet the satellite TV receiver uses an infrared emitter to get its remote control commands. Just below the cabinet doors, a DVD player also uses an emitter to receive commands from the cockpit or slip.

The factory Clarion source unit and CD changer is concealed behind a smoked glass door. The Clarion’s auxiliary input is used to provide theater sound from the satellite TV receiver or DVD player.

A radio frequency remote fob controls the theater sound volume without having to get up and access the Clarion source unit.

Just inside the cabin door switches provide instant and independent cut-off of the cabin and cockpit audio systems.
 
 Concealed within an overhead salon cabinet we built in a white laminated electronics control panel. The panel contains the Glomex UHF/VHF amplified antenna control, the KVH on/off switch and diagnostic port, the salon’s theater sound center channel level control, the salon’s bass level control, the ship-to-shore satellite TV antenna selector, plus the cockpit audio system equalizer and zone controls. Everything is labeled for EZ operation.

A flush ceiling-mounted Boston Acoustics NX series 6 1/2-inch coaxial is used as a center channel speaker. The factory grill cloth has been replaced with a more acoustically transparent material.

Silver Canton miniature two-way speakers are used for the left and right front satellite channels.

Canton speakers concealed behind the blinds deliver the surround sound left and right rear fill.

Separate left and right 8-inch subwoofers are concealed underneath the salon couch.

Behind the salon couch a JL Audio six-channel amplifier drives the salon’s two subwoofers and five satellite speakers.

In the master stateroom we upgraded the speakers to Boston Acoustics. We also modified the speaker mounting bezels to be more open and applied a new and more acoustically transparent grill cloth.

Concealed within a cabinet we installed a dedicated volume control in the master stateroom.

Just below the TV/DVD combo in the master stateroom, we installed an infrared target for full control of the satellite TV receiver.

We programmed this universal remote control with separate screens for each zone, including salon, cockpit and boathouse. Custom macros provide one touch master on/off control for multiple components. This remote control can be programmed for either IR or RF operation as it applies to each component.

We also programmed the universal remote control to operate the Sea Ray’s factory air and heat controls.

Additionally, EARMARK offers a broad range of lighting options. In particular, an amber (doesn’t attract bugs) LED array outlines the slip for easy docking at night. The system is controlled via a small radio frequency fob so that you can activate the system when approaching the boathouse. We also have step and courtesy light packages in just about any color for on the boat.
