Digital Control Head
The Digital Control Head is the heart of the ADVANCED entertainment system. It provides
control, and monitors the functions of the various system components. It incorporates digital
microprocessor technology to perform its various functions, which include the following:
-Audio level control of the passenger's audio.
-Separate speaker zone selection.
-Four selectable Passenger's audio inputs; Radio, Video 1, Video 2, and CD.
-Remote VCP control of Play/Stop and Rewind operations.
-Remote CD Changer control of Play/Stop, Disc up, and Track up.
-Three PA input lines; two with separate volume levels.
-Audio level control of the Driver's audio level.
-Two selectable Driver's audio inputs; Radio and CD.
-Serial communications controller.
The Public Address function of the system is controlled by the Control Head. There are three
primary microphone inputs. When any one of these inputs become active, the system switches
over to its PA mode. The display will indicate `PA' and all other audio will be muted. Any
sound going into the microphone will be heard over the passenger's speakers. While the PA is
active, the volume level for that PA channel may be adjusted using the volume up and down
buttons on the front of the Control Head. The last audio level used for each channel is retained in
memory for that channel until it is re-adjusted or the Control Head is reset to its factory set
default audio levels. PA1 channel has priority over PA2 channel. The PA system will
automatically activate whenever a microphone is keyed, even if the Control Head is not turned
on. There will be a short delay before audio can be heard over the speakers while the amplifier
powers up. During this period, the display on the Control Head will indicate 'WAIT'.

dome tweeters; and two 8 inch bandpass subwoofer enclosures. The full range speakers are
mounted on the sloped area of the parcel rack, angled towards the widow to reflect their sound
back into the passenger's listening area providing clear separation and a full range of audio. The
tweeters are mounted along the upper edge of the parcel rack, angled down towards the listening
area providing clear high-frequency response. These 30 tweeters and full range drivers are
divided into 4 distinct channels. One channel for the right rear, one for the left rear, one for the
right front, and one for the left front. This allows for customized listening zones and the tailoring
of the sound to match the coach environment. The front channels, both right and left, consists of
2 tweeters and 2 full range drivers. The rear channels consist of 5or 6 tweeters and 5 or 6 full
range drivers. Since the right side parcel rack is shorter, the right side rear channel has only 5
tweeters and 5 full range drivers. The front and rear channels may be individually selected via the
speaker button on the Control Head, giving the option of a 'quiet' zone within the coach. The two
8 inch subwoofer enclosures are mounted in the luggage compartment area, one in the right front
and one in the left rear. Their sound is passed into the coach interior via three 2-1/2 inch ported
tubes. The subwoofers have a dedicated channel from the amplifier, allowing for independent
level adjustment. These units are designed to pass frequencies between 42 Hz. to 200 Hz. which
produce a impressive bass response that, when combined with the tweeters and drivers, give a
full range of high-fidelity sound.
A-29
Video System
The Video System on the Renaissance Coach utilizes REI's custom 10 inch, 24V monitor that
now features enhanced picture quality to offer video entertainment to the passengers. The
supporting pieces of equipment have been designed to incorporate flexibility, modularity, and
total integration that allows the user to control and monitor the various pieces. The system is
controlled by the dash mounted Control Head. It is its responsibility to activate the system,
monitor it, and provide remote operation of it while displaying the system's current operating
parameters. The basic Video System consists of the following components:
-Digital Control Head.
-10 inch, 24V, slide mounted video monitors.
-Video cassette player (VCP).

The Digital Control Head is mounted in the dash and is used to monitor and control the operation
and functions of the Video System. It may remotely control the Play / Stop and Rewind
functions of the VCP along with selecting between two video sources.
The 10 inch, 24V video monitors are mounted beneath the parcel racks on custom trim panels
and feature a patented slide bracket that allows for easy insertion and removal. The monitors and
brackets are covered with soft foam covers for esthetics and safety.
The Video Cassette Player is mounted in the modular equipment rack located in the left front
parcel rack. It functions as the main video source for the monitors and may be remotely
controlled and monitored via the Control Head. It plays standard VHS tapes.
The Video Control Module is also mounted in the equipment rack and serves as a video
distribution amplifier along with controlling the power to the monitors and switching between
two sources of video.
The Power Distribution Module is a centralized power filtering and distribution point for the
system, supplying both 24 and 12 Volts to the system.
The UHF/VHF Tuner is mounted in the equipment rack and may be used to receive and display
off-the-air television transmissions on the monitors.
The Scenic View Camera is mounted on the dash and provides the passengers the same view as
the driver via the monitor system.
V-1
24V, 10 inch MONITOR
The 10" Monitors provides the video picture to the passengers. They are mounted strategically
throughout the coach to provide optimum viewing at all seat locations. The units are specially
designed to operate at 24V and manufactured specifically for the coach environment. They are
housed in an all-steel chassis that features a tapered design for increased headroom. Each
monitor has individual controls, located in the monitor's rear panel, for vertical hold, vertical
size, contrast, brightness, horizontal hold, color and tint. These adjustments are preset at the
factory, but may be fine-tuned by the operator to custom tailor the picture to their viewing
requirements. It receives its video signal via a 75-ohm coax from the Video Control Module
mounted in the equipment rack in the parcel area. It uses an NTSC unbalanced video signal.
The power is also supplied via the VCM and is switched on only when the video system is
activated by the Control Head. When the system is in Video mode, and the monitor is on but no
video signal is present, (i.e. no videotape is playing, etc.), the monitor will display a blue screen.
CUSTOM MONITOR SLIDE BRACKET
The patented Slide bracket is the accompanying mount used for securing the monitor and
provides easy installation and removal of the monitor. Power and video is transferred into the
monitor through special blind mate connections, so no external wiring to the monitor is required.
The monitor is secured in place via a key lock located on the rear of the unit to lock the monitor
into position. All monitors use the same key, and therefore, any key can be used in any position.
The slide bracket has one 4-pin connector that is used to carry power and a BNC connector for
video. The slide bracket is secured with four 1/4-20 bolts to a trim panel attached to the parcel
rack by T-bolts that are inserted into a T-channel within the rack. See installation guide for
further details.
V-4
ADVANCED V-3000 12V VCR
The ADVANCED V-3000 VCR is a custom manufactured 12V video cassette player designed
specifically for use in the coach environment. It incorporates upgraded circuitry and mechanics
for durability. The unit is mounted in the modular equipment rack located in the front left parcel
area behind the driver, and receives its power from the VCM when the Video system is activated.
In return, it supplies a NTSC video signal to the VCM for distribution to all monitors. This
video signal is connected via a coax cable with a BNC connector labeled 'VIDEO OUT'. Power
and serial data is transferred to the unit through a 10-pin connector on the rear chassis labeled
'VCP CONNECT'. The machine may be remotely controlled from the Control Head, (only while
in the Video Mode). Functions that may be accessed include PLAY/STOP, and REWIND. The
unit may also be directly operated by the front panel controls on the player itself. Other features
include an auto-repeat mode to continually play the same tape without operator intervention,
push button up and down tracking control, and a integral dew sensor, that detects the presence of
moisture and prevents the machine from operating, protecting both the machine and tape from
possible damage. The dew sensor indicator, located on the front of the player, comes on when
the sensor circuit is active. The Control Head will also indicate this condition by displaying
DEW. Upon initial insertion of the video cassette tape, there will be a short time of picture
instability while the auto-tracking feature of the machine is operational. Once the auto-tracking
has locked onto the correct tracking setting, the video picture will become stable. As previously
mentioned, this control can also be manually adjusted.
*NOTE: Please observe all CAUTION and WARNING labels on the video player. They warn
against using the machine during cold temperatures without a proper warming up period and also
forcing a tape into the unit, which may cause damage or possibly break the loading mechanism of
the machine.
V-17
VIDEO CONTROL MODULE
(VCM)
The ADVANCED Video Control Module, or VCM, is a customed designed video signal and data
communication center for the video system. The unit is mounted in the bottom slot of the
modular equipment rack in the front left parcel area behind the driver. The module is positioned
so that the power and video connections are made through an opening on the right side of the
rack. The VCM is responsible for the distribution of switched power, and the video signal from
a video source (VCP, Tuner, or other video equipment) to the monitors through a 4 pin connector
and an associated BNC connector for each monitor present. The monitor connections are divided
into two banks, labeled VIDEO OUT 1 and VIDEO OUT 2 on the VCM . The 4-pin connector
carries power and ground to each monitor. This power is internally switched on and off by the
VCM when instructed by the Control Head. Power is only turned on when the system is in the
video mode. This switched power is supplied to the VCM from the Power Distribution Module,
(PDM), where it is filtered and conditioned. Each power line is individually protected against
over-current conditions. The unit itself has a 20 Amp circuit breaker located on the right side of
the module labeled Main Breaker. The video signal is distributed to each monitor through the
BNC connection made for that monitor directly above the 4-pin connector. The VCM conditions
and amplifies the video signal to provide a stable signal regardless of the number of monitors
within the system. The VCM will automatically detect the presence of a video signal and
indicate this condition via the LED labeled VSP (Video Signal Present), located on the left side
of the unit. In the absence of video, the VCM produces a sync signal that stabilizes the picture
and produces a blue screen on the monitors. The unit is capable of accepting two separate video
sources, labeled Video A and Video B, and switching between these two sources via the Control
Head, using the VID 1 and VID 2 button. The video sources are connected to the VCM through
a 10-pin connector and an associated BNC connector. The 10-pin connection carries audio, data,
and power. The associated BNC carries the video signal. Whichever video source is selected will
be distributed to all the monitors present. Control of the selected video sources is transferred at
this time. The selected video source is indicated by its associated LED, (labeled Video A and
Video B) on the left side of the VCM. The Control Head will also indicate which video source is
selected, both by illuminating the corresponding LED, (VID 1 or VID 2) and by displaying VID 1
or VID 2. If a second source is selected, but is not present within the system, (i.e. not connected
to the VCM), the Control Head will display the message NO VID 1 or NO VID 2, depending on
which source is not used. There are also separate gain controls to adjust the relative audio level
from each video source. These controls are located on the left side of the unit and labeled Audio
Input Level A and B.

antenna). This system switches between the two antennas to locate the strongest signal from the
microphone. The antenna in use is indicated by lighting either the A or B LED. The wireless
microphone is also capable as acting as a sing-a-long microphone that allows the user to mix
their voice with the current audio source being played through the Passenger's speakers. This
function is enabled by toggling the Normal / Sing-a-long button. When the sing-a-long function
is active the LED inside the button illuminates. When in the normal mode, the wireless acts as a
PA override microphone, muting all audio except for the microphone source. Both the receiver
and the microphone have manual channel selectors. The channel is set with a small screwdriver
and both the channel selectors on the microphone and receiver must match.
The unit is a FCC approved device operating on the following 16 frequencies:
175.000 MHz
175.300 MHz
175.600 MHz
175.900 MHz
176.200 MHz

12V, UHF\VHF TELEVISION TUNER
The 12V Tuner is capable of receiving both UHF and VHF television broadcasts and displaying
them on the monitors. The unit is mounted on the right side of the modular equipment rack
located in the front left parcel area behind the driver. The tuner receives 12V power from the
Power Distribution Module, (PDM) via the 6-pin connector at the rear of the unit labeled 12V.
For optimum reception, the tuner requires an external UHF\VHF antenna to be connected to the
Antenna In jack, also located at the rear of the unit. The received channel is split internally into
separate audio and video signals. The video and audio outputs of the tuner are connected to the
video and audio inputs of the VCP to be displayed on the monitors. The tuner has a red LED that
indicates power is present. This LED becomes brighter in intensity when the unit is turned on
via the power button on the front. There are three channel control buttons labeled AUTO,
CHANNEL UP, and CHANNEL DOWN also on the front of the unit. The AUTO channel
button is pressed to automatically program the unit to receive broadcast signals of sufficient
strength to produce a viewable picture. The channels programmed will vary with geographical
location and signal strength. The CHANNEL UP and CHANNEL DOWN buttons increment or
decrement respectively the programmed channels within the unit's memory. As the coach travels
to different locations, the auto-programming feature may need to be repeated to update the tuner's
channel memory for that broadcast area.

Remote Command Module
The Remote Command Module (RCM) duplicates all the functions of the Digital Control Head
of the ADVANCED entertainment system. The RCM was designed for a tour guide and works
in conjunction with the Digital Control Head. The RCM provides control, and monitors the
functions of the various system components. All functions entered at the RCM are sent to the
Digital Control Head via the serial interface. The RCM incorporates digital microprocessor
technology to perform its various functions, which include the following:
-Audio level control of the passenger’s audio.
-Separate speaker zone selection.
-Four selectable Passenger’s audio inputs: Radio, CD, Video1, and Video2.
-Remote VCP control of Play/Stop and Rewind operations.
-Remote CD Changer control of Play/Stop, Disc Up, and Track Up.
-Three PA input lines: two with separate volume control.
-Displays Driver’s audio status.
