II. **SYSTEM OVERVIEW**

    A.  Objective

        1.  The park is renovating and adding on to their Visitor
            Center. Part of the existing building will become a Theater
            requiring an audiovisual system with automated control.

        2.  Provide a fully functional and operating audio and video
            playback system comprised of Contractor provided and
            Government-Furnished equipment and materials at the Visitor
            Center Theater at the George Washington Carver National
            Monument. The system's primary function is to present
            visitors with a Park orientation film from a DVD player.
            Operation of a single illuminated pushbutton located at the
            Visitor Center Information desk shall cause the film (DVD
            Video) to start play in an automated mode.

        3.  The AV system will be comprised of a DVD Video player, AV
            receiver/amplifier, loudspeakers, video projector,
            microprocessor based media player controller. In addition,
            miscellaneous cable, connectors, relays, custom panels, and
            hardware as necessary to fabricate and install the system in
            a professional and craftsman-like manner and operable as
            described here.

    B.  Operation

        1.  The Park Staff will start the AV presentation from the
            control panel at the information desk. They will also be
            able to monitor the program audio from this panel.

        2.  Park Staff will start-up the system at the beginning of the
            day with a single pushbutton on the control panel at the
            equipment rack. This will power on the projector, audio
            receiver/amp and DVD player and the show will play for one
            minute when the projector is fully functional. Staff will
            then check the AV show verifying proper operation of system
            components.

        3.  Park Staff will stop the programs at the end of the day with
            a single pushbutton on the control panel at the equipment
            rack. This will power down (or stand-by mode) the projector,
            audio receiver/amp and DVD player. Staff will verify a
            proper shut down.

        4.  The equipment rack will normally remain powered up 24 hours
            a day, 7 days a week. A switched power strip on the front of
            the rack will allow the AV equipment to be turned off when
            required. This may occur during extended Visitor Center
            closures or dangerous storms.

        5.  In addition to its automated show, there will be auxiliary
            input sources for special presentations. Park staff will
            select the auxillary sources from control panel at the rack.
            They will operate the auxiliary player(s) by the player's
            front panel controls or IR remotes.

             width electronic apparatus in 1.75" height increments. The
             rack will accommodate 70" (40 rack unit spaces) vertical
             mounting height. The Contractor shall install all AV system
             equipment in the rack in a fashion similar to the
             accompanying elevation. Equipment not manufactured for
             traditional rack mounting methods shall be provided with a
             rack mount shelf sized appropriately for that equipment.

        signal levels must be maintained throughout. Crimp type
        connections shall be accomplished with ratchet type crimping
        tools as recommended by the crimp connection device
        manufacturer. Possession by any Contractor employee or personnel
        under the Contractor's supervision of a single-action crimp tool
        on the job site will be sufficient evidence to require the
        Contractor to reconstruct all such connections in the work. Use
        of gender adapters; video or audio connection adapters;
        prefabricated, molded, or modular connecting cables are
        prohibited for use in these systems. Unused conductors, shields,
        or drain wires shall be dressed under heat shrink tubing not
        cut. Label all cables with a unique ID number, optionally with
