WELCOME
Dear Fellow ADCOM Product Owner,
Welcome to the ADCOM family! For more than twenty years, ADCOM products have delivered
excellent performance and value for customers around the world. Our products are designed by
our experienced and demanding engineering team, built to the highest standards in our factory,
and sold and serviced through dealers, custom installers, and other retailers whose primary goal
is your complete satisfaction.
We know you are anxious to see and hear your new DVD player in action, but please take a few
minutes to read this owner’s manual before connecting the DVD player to your system. It is
particularly important that you connect your DVD player to your preamplifier while the ampli-
fier and preamplifier are unplugged and your other equipment is turned off. This will protect
your equipment from potential short circuits that may occur during installation. In addition, it is
important that you allow for adequate ventilation around your DVD player and other equipment,
since excessive heat buildup can shorten the life of any electronic product, including the DVD
player. Once you have correctly connected your new DVD player to your other components, you
should be able to enjoy many trouble-free years of performance.
We conduct a thorough quality and performance test on each and every DVD player we build in
our factory prior to shipment. In the rare case of a defect that may occur after shipment, we
stand behind our DVD players with a two-year parts and labor warranty. To register for this war-
ranty, please complete and mail the enclosed warranty card back to ADCOM. Also, please keep
a copy of your sales receipt with the owner’s manual so you may provide proof of eligibility for
the warranty should the need arise.
We know you will be very happy with the audio and video performance of your new DVD player. We
hope you will also consider other ADCOM products, such as our line of multichannel amplifiers and
preamplifiers. In addition, we design and manufacture complementary products such as surge sup-
pressors and speaker selectors. Please visit our web site at www.adcom.com to learn more about

for physical imperfections and tested
for all electrical parameters as a
routine part of ADCOM’s systematic
quality control. This, along with full
operational and mechanical testing,
should ensure a product awless in
both appearance and performance.
After you have unpacked the GDV-850,
inspect it for physical damage. Save
the shipping carton and all packing
material as they are intended to
reduce the possibility of transportation
damage should the DVD player ever
need to be shipped again. In the
unlikely event damage has occurred,
notify your dealer immediately and
request the name of the carrier so
a written claim to cover shipping
damages can be initiated. The right to
a claim against a public carrier can be
forfeited if the carrier is not notied
promptly in writing and if the shipping
carton and packing materials are not
available for inspection by the carrier.
Save all packing materials until the
claim has been settled.

1.4 Input & Output
System Connections
Like the front panel, the GDV-850’s
rear panel is carefully arranged to
make hookup, configuration, and use
as simple as possible. However, the
GDV-850’s capabilities take some study
to use most effectively. We strongly
suggest that you read this section of
the manual before beginning to hook
up your player. You will save yourself
much time and effort if you carefully
think out what you expect from your
system, consider the components you
will use, where they’ll be placed,
and how you will want them to work
together. The notes in this section and
the connection diagrams that follow
will probably answer most of your
questions about interfacing the GDV-
850 into your system.
[11] Region Code
The GDV-850 is configured for use in spe-
cific geographic locations. Geographic
regions around the world are assigned a
numeric code by the DVD forum which is
indicated on this icon. See section 7.0 of
this manual for more information.
[12] Component Output
Use this output to connect the GDV-850
to a preamp that accepts component
video input or directly to your display. A
component video signal typically refers
to Y/Pb/Pr, which consists of three
75-ohm channels: one for luminance
information, and two for color.
[13] Video Format Switch
With the GDV-850 you have the abil-
ity to switch between progressive-scan
(480p) and an interlaced (480i) video
signal. Use this switch to set the video
output format. When the progressive
output is selected the S-video and
composite outputs are disabled and the
progressive status indicator on the front
panel will illuminate.
[14] S-video Output
S-video may also be referred to as
Y/C, the abbreviation for luminance/
chrominance. The S-video cable uses
a four-pin connector that is most com-
monly used with VCRs and DVD players.
S-video delivers a better picture than
composite connections and should be
used whenever possible unless you can
use component connections, which typi-
cally deliver better video than S-video.
[15] Composite Output
Composite video is used in nearly all con-
sumer video devices. Both chrominance
and luminance signals are carried on the
same 75-ohm RCA cable. Chrominance is
carried in a 3.58-mHz (NTSC) sideband
and filtered out by the TV’s notch or
comb filter. Poor filtering can result in
dot crawl, hanging dots, or other im-
age artifacts. We recommend using this
output only when component or S-video
inputs are not available.
[16] RS232 Input
Allows control of the GDV-850 via com-
puter or home automation system. A DB-9

cable is used to make the connection to
the GDV-850. Refer to section 2.3 for
more detail.
[17] Analog Audio Output
Using the analog audio output allows
the internal DSP and DACs to decode
and convert the data from the disc to
analog signals. This output is used when
connecting the player to an analog stereo
preamp, and is necessary for use in many
distributed audio setups. This output
can also make use of analog direct
modes available on many preamplifiers
like ADCOM’s GTP-880.
[18] 5.1 Audio Output
To enjoy the high resolution playback
of multichannel DVD-Audio discs,
connect these six RCA jacks to the 5.1
analog inputs on your preamplifier or
receiver. Use six separate RCA cables
to make the connection to your pre-
amp. Due to copy protection issues,
the digital output may need to be off
during playback of DVD-Audio discs.
[19] Digital Audio Output
Dolby Digital and DTS movie sound
tracks will be sent to your preampli-
fier via the digital audio output. Your
preamplifier must be able to decode
Dolby Digital and/or DTS digital sig-
nals. Otherwise, you will need to use
the GDV-850’s 5.1 analog outputs to
enjoy Dolby Digital and DTS sound.
[20] 12V DC Trigger
A trigger, if properly hooked-up, can prove
to be very convenient. Use the 12V DC
trigger in conjunction with your preamp
to turn the player on and off. The trigger
output from your preamp should go in to
the trigger input on the rear panel of the
GDV-850. A pass-through output jack is
provided to allow trigger control of ad-
ditional components in your system.
[21] IR Input
Use the IR input jack to connect an
external IR sensor to the GDV-850
when the unit is installed behind doors
or where it is not otherwise visible to
the remote.
[22] Voltage Switch
Before plugging the unit in make sure
the voltage is set to your country’s
voltage configuration. The GDV-850
should be unplugged prior to flipping
this switch. If you are uncertain, please
have your installer or dealer verify
before proceeding.
[23] Main AC Power Switch
Turns the current to the GDV-850 on
or off. Setting this button to the on
position supplies power to the unit,
enabling use of the standby power
button on the front panel. When the
main power switch is in the off posi-
tion, current is cut off to the unit.
[24] IEC AC Input
Use to connect the supplied IEC re-
movable AC power cord (see page 2
for all warnings). Before proceeding,
please observe the following precau-
tions when connecting devices to your
new GDV-850.
Do not plug the power cord into your
GDV-850 until all other connections
have been made.
Insert the supplied power cord into
the AC input of the rear panel of the
GDV-850. Do not use a power cord
other than the one supplied with the
GDV-850. It’s designed for use with the
GDV-850 and should not be used with
any other device.
Caution: Before you plug the power cord
into an AC wall outlet, confirm that all
connections to the GDV-850 have been
made correctly.
Warning: Never disconnect the power cord
from the GDV-850 while the other end is
plugged into an AC outlet. Doing so may
cause an electric shock. Always connect
power by plugging into the AC outlet last
and disconnect by unplugging from the AC
outlet first.

2.2 Remote Overview
The GRC-815 remote control is a pre-
programmed remote control that has
been designed specifically to work
with the GDV-850 DVD player. While
a disc is spinning up and playing the
opening title sequences, some func-
tions may be non-functional.
NOTE: A hand icon is displayed when
a button press is not a valid operation
accepted by the unit for the disc you
are playing.
Alkaline batteries are recommended
for maximum operating life. Two AAA
(R 03) batteries should be fitted into
the battery compartment at the rear
of the remote control. When replacing
batteries, check that they have been
put in correctly, as indicated in the
battery compartment.

[48] Menu Button
The menu button will always display
the menu for a disc when pressed. If
pressed when in a playback mode, the
location is marked and play may be
resumed by using the resume button
on the remote, as described below.
[49] Navigation Buttons &
Select Button
This group of buttons is used to navi-
gate the OSD for the menus of the DVD
player itself and the menus for discs
during playback. This group of buttons
is comprised of four direction buttons
and a select button in the center.
[50] Subtitle Button
The subtitle button will display subti-
tles in languages available on the disc.
Continue to press this button to cycle
to the next language or to turn sub-
titles off. If a preference has been set
to display subtitles in the DVD player’s
setup menu, making this selection
during playback will only affect that
single playback of the DVD-disc.
[51] Zoom Button
Use the zoom button to magnify the
video track. Press the zoom button to
first set the magnification to a level of
X1.5, pressing this button again will set
the level to X2.0. Use the navigation
buttons to move to different areas of
your magnified image. The movie will
continue to play while the zoom fea-
ture is active. To exit the zoom mode
press the zoom button a third time.
[52] Angle Button
An angle is a scene recorded from dif-
ferent viewpoints. Each angle is equal
in time length, and an angle block may
contain up to nine (9) angles. Pressing
this button will cycle through any
available angles. If none are available
a white hand will be displayed.
[53] Resume Button
The resume button functions much
like the play button and will resume
playback when using other functions
of the DVD player, such as slow/step
or while in the menu.
[54] RGB Video Output Button
Pressing this button turns the optional
RGB video output on. Note: This fea-
ture may be disabled in some regions
due to copy protection requirments.
[55] Compnt (Component)
Video Output
Pressing this button turns the compo-
nent video output on. Note: This fea-
ture may be disabled in some regions
due to copy protection requirments.
[56] Digital Audio Out Off
Pressing this button turns the digital
audio output off. When turned off
the GDV-850 will output the highest
resolution signal via the analog out-
put jacks. Note: This feature may be
disabled in some regions due to copy
protection requirments.
[57] Digital Audio Out On
Pressing this button turns the digital
audio output on. The bitstream select-
ed on disc will be sent to preamp. Due
to copy protection requirments, when
playing a DVD-Audio with digital audio
out on, DVD-Audio will be truncated to
16bit/48k operation.
2.3 RS232 / IR Control
The Adcom GDV-850 can be controlled
via its serial RS-232 port. The serial port
can be connected to a PC or ‘dumb ter-
minal’ via a straight-through standard
9-pin serial port cable (MALE on one
end and FEMALE on the other end).
When using a PC, a terminal emulator pro-
gram, such as ProComm or the Windows
“Terminal” program can be used.
The communications parameters
should be set as follows: 9600 baud,
8 data bits, no parity, 1 stop bit and
Hardware Flow Control
Some of the commands can only be sent
to the Video Switch when it has been
‘unlocked’. This protects it against
inadvertent re-programming of its
serial number, and its default settings.
NOTE: all commands are CAPITAL let-
ters (ASCvII characters)...lower case
letters, or unrecognized commands
are ignored and a ‘?’ may be returned.
Data bytes associated with a command
can be upper or lower case letters and
numbers as appropriate.
Commands can only be entered after
the “>” prompt character is displayed.
The exception to this rule is that the
GDV-850 does not echo the command
prompt when first plugged in. After
the first command is received, prompts
are then automatically generated.
When a command has been received,
the command letter is echoed, fol-
lowed by a CR/LF, then “>” as a
prompt character.
If the command is one that returns
data (e.g. “S” – Status), then the data
is returned, followed by the echoed
command letter, and a CR/LF, then
“>” as a prompt character.
Command echoing can be turned on and
off by issuing the ”E” command (see
below). The GDV-850 echoes commands
by default on line cord power-up.

3.4 OSD Overview
The GDV-850 displays icons, status
indicators, and interactive menus on
the TV monitor. Many of these screens
are used to set up preferences and
activate advanced features of the
unit. Others offer information and
choices useful during normal opera-
tion of the unit.
NOTE: The default language for all
GDV-850 On-Screen Displays can be
changed. See the General Setup topic
in the Setup section of this manual.
Status Indicators
During operation of the unit, various
status indicators appear on screen
such as NO DISC, LOADING, PLAY,
PAUSE, etc. These information displays
are self-explanatory. When using spe-
cific features during playback (such as
Language selection, Time Display,
Repeat Mode, etc.), indicators appear
in the On-Screen Display showing the
current status of that feature as you
make changes.
NOTE: A hand icon is displayed when
a button press is not a valid operation
accepted by the unit for the disc you
are playing.
Menu Screens
A number of menu screens can appear
during configuration of the GDV-850
such as the sample below:
The menu screens provide access to
various settings and features described
in the next section of this manual. The
menu system appears when the setup
button is pressed, typically whether
the disc or stopped or playing. The
on-screen display (“OSD”) menu does
not appear when a DVD-A disc is play-
ing. The Preferences menu screens
are only available when disc playback
is stopped.

GDV-850 Setup Menu
4.1 Setup Overview
All congurations for the GDV-850 are
made in the setup menu. The setup
menu is displayed on the OSD and
accessed with the setup button on the
GRC-815 remote control. When the setup
button is pressed your source material,
if playing, is paused and a transparent
blue menu is displayed over the source
video. Please note that not all options
can be modied while source material
is active. Use the navigation keys on the
remote to navigate the setup menu, all
selections will be saved when you exit
setup. Pressing the setup button while in
the setup menu will exit the menu and
playback of your material will resume.
Changes can be made to the GDV-850 in
four main areas: general setup, speaker
setup, audio setup and preferences.
4.2 General Setup
The General Setup page provides a
number of setup items relating to the
type of TV monitor, progressive scan-
ning, and the appearance of On-Screen
Displays and the front panel display.
TV Display
The TV display option allows the DVD
player video output to be congured
to match the size of your TV and your
viewing preferences. First, you need
to decide which type of TV you are
using. There are two different aspect
ratio TVs available today: standard (4:
3) and widescreen (16:9). If your TV is a
widescreen set, then you should select
the “widescreen” option. If your TV is
the standard 4:3 then you should select
either pan/scan or letter box. The let-
ter box option will display black bars at
the top and bottom of the picture when
you are watching widescreen material.
If you don’t want to see the bars, then
you should select the pan/scan option.
When you are viewing widescreen mate-
rial, the pan/scan options cuts off the
extreme left and right sides of the pic-
ture, and lls your entire TV screen.
PIC Mode
This setting optimizes the Progressive
Scan mode. The setting is only in effect
if you are using an NTSC TV monitor.
It has no effect unless your monitor
accepts progressive scan video signals
and the GDV-850’s Progressive Scan fea-
ture is activated. Progressive scanning
combines two interlaced (480i) elds
into a single progressive (480p) image
for display on digital monitors. When
source material was originally lmed
with video cameras, this is a relatively
straightforward digital conversion since
video is shot with a frame rate of 60
interlaced frames per second which
is then displayed at 30 progressive
frames per second. However, mate-
rial originally shot on lm presents a
more difcult challenge since it was
shot at a frame rate of 24 frames per
second. When converted to video with
30 frames per second, this material may
show artifacts on fast motion scenes. An
advanced lm mode technique known
as reverse 3:2 pulldown improves the
picture with lm-based recordings.
Auto
The GDV-850 recognizes the picture
type based on ID codes embedded at
the start of the disc.
Film: This option activates the reverse
3:2 pulldown feature and is optimized
for lm source images. It should only be
used to force the progressive scanning
into lm mode.
Video
This option is optimized for video source
material and is used to force the progres-
sive scanning into video mode.
Smart
The option may be best for discs with
mixed lm source and video source
material that cannot rely on an identi-
fying code inserted at the beginning of
the disc. The GDV-850 senses the type
of recording for each scene and adjusts
the progressive scanning accordingly.
Super Smart
This option is the default setting and
usually provides the best performance.
In addition to activating lm or video
modes based on embedded codes, it
analyzes the video signal in real time
and uses motion adaptive interpolation
to optimize the display for rapidly moving
images or still images.
Angle Mark
You can choose whether or not to have
the unit display an angle icon in the
corner of the screen to inform you

| ADCOM GDV-850 Owner’s Manual20
21ADCOM GDV-850 Owner’s Manual |
when alternate angles are available
for a scene on a DVD Video disc.
On: Activates the display of the angle
icons, indicating that alternate angles
are available for the current scene.
Off: Turns off the display of angle icons.
Note: Even with Angle Mark off, the
angle icons appear when the ANGLE
button on the remote is pressed.
OSD Language
The language that the OSD displays may be
changed to your preference. The options
are English, Chinese and German.
Last Memo
Some DVDs have the ability to let you
watch part of a movie, take the disc
out, then re-start the movie from
where you left off. Not all discs have
this feature.
Captions
Much like subtitles, captions are a tex-
tual representation of the audio infor-
mation in a video program. Captions
are usually intended for the hearing
impaired, and therefore include addi-
tional text to identify the person speak-
ing, off-screen sounds, and so on. The
options are on and off.
Scr (Screen) Saver
After your player sits idle for a few min-
utes the screen saver will be activated.
This option will help to increase the
life span of your monitor by preventing
images from burning into the display.
The options are on and off.
IRE
Grayscale in video is measured and
tracked on a scale of 0 (black) to 100
(white) IRE units. In NTSC video is tradi-
tionally assigned the 7.5 IRE value as being
the black cutoff in a picture. Setting the
output to a 0 IRE signal will present richer,
deeper black tones in every image. The
options are IRE 0 and IRE 7.5.
Dimmer
The brightness of the front panel display
can be reduced to avoid distraction while
viewing in a darkened room. To adjust, use
the CURSOR buttons to select a setting
on the vertical slider control on the right
side of the menu screen. A setting of “1”
is the brightest setting. A setting of “7” is
the dimmest setting. The “OFF” setting
turns the front panel display off.
4.3 Speaker Setup
Speaker setup is an important step to
ensure you get the most out of your
system.
