Congratulations on your decision to
purchase the GTP-860II 7.1 tuner/
preamplifier. Multichannel audio and
home theater are better than ever.
Your new ADCOM component was
designed to deliver all the impact
of your favorite action flick and the
subtle harmonic texture that makes
high resolution audio amazing.
Audition the GTP-860II paired with
an ADCOM power amp and DVD player
and you will experience what high
performance is all about. To realize
the full potential of your GTP-860II,
and before making any connections
to it, please read these operating and
installation instructions thoroughly.
Key Features
• Dolby Digital and DTS decoding
• ADCOM 7.1m2
• Component video switching
• 24 bit/192kHz DACs
• RDS tuner
• External 5.1 input
• Torriodial power transformer
Unpacking the GTP-860II
Before your new ADCOM preampli-
fier left our factory, it was carefully
inspected for physical imperfections
and tested for all electrical parameters
as a routine part of ADCOM’s system-
atic quality control. This, along with
full operational and mechanical test-
ing, should ensure a product flawless
in both appearance and performance.
After you have unpacked the GTP-
860II, inspect it for physical damage.
Save the shipping carton and all pack-
ing material as they are intended to
reduce the possibility of transporta-
tion damage should the preamplifier
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 dam-
ages can be initiated. The right to a
claim against a public carrier can be
forfeited if the carrier is not notified
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.
Placing the GTP-860II
Although the GTP-860II does not
generate much heat, it is good prac-
tice to ensure the preamplifier’s
long-term, trouble-free operation to
provide adequate ventilation for the
unit. Therefore, the GTP-860II should
be kept away from external sources
of heat such as radiators and hot-air
ducts.
We recommend that you exercise care
when placing components on top of
the GTP-860II. If you are placing a
heat producing component (such as
an amplifier) on top of or below the
GTP-860II, it is recommended that you
allow at least three (3) inches vertical
spacing for proper airflow.
We also recommend that you leave five
(5) inches of space behind the unit for
additional airflow and to allow space
for interconnects to hang freely.
If you observe these recommendations,
the GTP-860II will perform reliably
in any reasonable environment. You
should also pay attention to such nor-
mal considerations as protection from
excessive dust and moisture.
The optimal performance of your new
GTP-860II will ultimately depend on
the care with which you make the con-
nections between the amplifier, pream-
plifier and loudspeakers. All input and
output signal connections should be
made only with high quality, low-loss,
low capacitance cables. For recom-
mendations of the type and quality of
interconnections that are best for your
applications, consult with your ADCOM
dealer.
Safety Information
There are no user serviceable parts
inside. Refer all servicing to qualied
service personnel.
The unit must be connected to a power
supply only of the type and voltage
specied on the rear panel. Connect
the component to the power outlet only
with the supplied power supply cable or
an exact equivalent. Do not modify the
supplied cable. Do not defeat grounding
and/or polarization provisions. The
cable should be connected to a 3-pin
polarized wall outlet, matching the
wide blade of the plug to the wide slot
of the receptacle. Do not use extension
cords. Do not route the power cord
where it will be crushed, pinched,
bent, exposed to heat, or damaged in
any way. Pay particular attention to
the power cord at the plug and where
it exits the back of the unit. The power
cord should be unplugged from the wall
outlet if the unit is to be left unused
for a long period of time. Immediately
stop using the component and have
it inspected and/or serviced by a
qualied service agency if:
• the power supply cord or plug has
been damaged;
• objects have fallen or liquid has
been spilled into the unit;
• the unit has been exposed to rain;
• the unit shows signs of improper
operation; or
• the unit has been dropped or
damaged in any way.

[3] Display Window
The display area shows all vital infor-
mation when the unit is operational.
[4] Volume Knob
The Volume control adjusts the over-
all loudness of the signals being fed
to the preamplifier outputs. Unlike
conventional controls, the GTP-
860II’s volume control doesn’t have a
start or end position. Volume can also
be adjusted from the remote control
using the Master Volume Up or Down
buttons [31]. The Volume control
does not affect recordings made using
the Tape, Video 3 and Video 4 outputs
but will affect the signal going to the
Preamp Outputs. The volume level is
indicated in the lower right hand side
of the front panel display and on the
OSD(On Screen Display).
On the remote control, press the
Mute button [29] to temporarily
switch off the sound to the Preamp
outputs and headphones. Mute mode
is indicated by “MUTE” in the display
area. Press Mute again to restore
sound. Mute does not affect record-
ings made using the Tape, Video 3
and Video 4 outputs but does affect
the signal going to the Preamp
Outputs.
[5] Headphone Output/
Video 5 Input
A 1/4” stereo jack socket is provided
for headphone listening and will work
with conventional headphones of any
impedance. The volume and tone
controls are operative for headphone
listening. Use a suitable adapter to
connect headphones with other types
of connectors such as 3.5mm stereo
‘personal stereo’ jack plugs. Inserting
a headphone will automatically turn
off the signals from the Preamp
Outputs, and set the listening mode
to Stereo.
REMEMBER: Listening at high levels
can damage your hearing.
The video five input is located on the
front panel to simplify connection of
a camcorder or a video game console.
To select video five, push the cor-
responding front panel button in the
input selector section.
[6] Surround Backs
Pressing this button engages ADCOM’s
proprietary 7.1m²™ decoding algo-
rithm as long as the surround back
speakers have been turned on in the
speaker setup section of the OSD.
The 7.1m²™ decoding process mixes
the signals from the left surround
and right surround channels to derive
two unique signals sent to each back
output. The benefit of our 7.1m²™
decoding process is enhance imaging
between the surround speakers and
the creation of a more diffuse ambi-
ent sound field. The 7.1m²™ process
has the same benefits when com-
pared to other matrix decoding as
stereo signals have over mono signals.
The 7.1m²™ process can also be used
to drive your surround back speakers
when you are listening to an exter-
nally decoded DVD audio or SACD
multi-channel disc. Due to the varying
nature of film soundtracks and music,
you may prefer to activate or deacti-
vate the surround back channels. For
example, Dolby Digital 5.1 and DTS
soundtracks benefit greatly from the
addition of the 7.1m²™ processing.
Pro Logic soundtracks on the other
hand provide a mono surround signal
track, which yields a less satisfying
experience when using the surround
back channels.
The level of the Surround Back chan-
nels can be adjusted in the same
manner as the other channels, either
through the On-Screen-Display (OSD)
or with the Bal. or Test functions
from the remote control. Be sure to
experiment to find the balance that
best suits your taste.
[7] Input Selector
These buttons select the active video
and audio input for the GTP-860II.
The source that is currently selected
will be shown on the top line of the
front panel display and the LED in
the source button will be red. On
the left side of the bottom line of
the front panel display the current
type of audio input will be displayed.
The audio input can be assigned to
the input select buttons using the
setup function as described in section
three of this manual. The currently
selected source signal is sent to the
main preamp outputs after process-
ing and the video 3, video 4, aux and
tape outputs. Video signals associated
with an input give priority to s-video
sources over composite video signals.
The video one and video two inputs
also have component video switch-
ing capabilities. This component
video switching is independent of the
composite/S video signal and does not
support on-screen display messages.
Ext 5.1: Selects the multi-channel
output signal from a DVD player or
external decoder source (such as
DVD-Audio) connected to the ext 5.1
input as the active input. This func-
tion can be selected for each source
using the On screen setup functional-
ity as described in section three of
this manual.
Tape Monitor: Selects the output
from a tape recorder when playing
back tapes or monitoring recordings
being made through the Tape sockets.
Press the Tape Monitor button once
to select it and again to return to the
normal input selection.
The Tape Monitor function does not
override the current input selec-
tion that is sent to the tape outputs.
When the Tape Monitor is selected,
you are listening to the signal that
is coming back into the Tape Input
jacks. The currently selected source
is still being sent to the Tape Out
where it can be recorded. This

| ADCOM GTP-860 II Owner’s Manual8
9ADCOM GTP-860 II Owner’s Manual |
function enables you to check on a
recording that you are making with-
out affecting the recording process.
When Tape Monitor is selected, the
button will remain lit until Tape
Monitor is disengaged again. This
function is only active when a stereo
analog source is selected.
[8] Surround Mode
With the Surround Mode button the
available surround sound modes can
be selected. The selected surround
mode is permanently indicated in the
display area on the right side of the
top line of the display. The Surround
Mode button scrolls through the avail-
able surround sound modes when
pressed repeatedly.
The surround modes are:
Stereo: The Stereo mode provides
signals to the front left and right
speakers and possibly the subwoofer.
Hall: In the Hall Surround mode, a
realistic level of ambiance is added
to a normal stereo source such as a
CD or FM radio.
Pro Logic II: Dolby Pro Logic II is the
new advanced version of Pro Logic,
Dolby’s original surround matrix with
center channel output. Pro Logic
II has enhanced imaging and wider
bandwidth surround signals than
original Pro Logic. Dolby Pro logic II
is intended for use with most mov-
ies and television programs that are
designed to be listened to using Pro
Logic decoding. In addition to the
standard Dolby Pro Logic II, which is
known as Prologic II Cinema(PLII-C).
“Pro Logic II Cinema”(PLII-C) is opti-
mized for movies and television. The
GTP-860II supports two other ver-
sions of Pro Logic II processing, which
were designed for specific types of
programs. “Pro Logic II Music” (PLII-
M)mode was designed for use with
regular stereo recordings and it can
utilize all your speakers in your sys-
tem when listening to a CD. “Pro
Logic II Panorama” (PLII_P)is a version
of Pro Logic II that is intended for
use with movie playback that spreads
the images from the front left and
right speakers around to the surround
speakers. The original Pro Logic pro-
cessing mode is also available.
5 ch Stereo: This mode is designed
for use with stereo program mate-
rial. It is designed to get maximum
output from all your speakers. The
rear speakers are driven with the
same signal as the front left and
right, while the center speaker is a
monophonic summation of the front
speakers.
With any of the Digital Inputs, the
GTP-860II automatically recognizes
if the selected source carries a Dolby
Digital™ or DTS™ signal. Dolby Digital
and DTS have six independent chan-
nels available in total: Left, Center,
Right, Surround Left, Surround
Right and an “Effects Channel”
(Subwoofer). With either Dolby Digital
5.1 or DTS digital input, the Stereo,
Dolby Pro Logic and Hall surround
modes cannot be selected. The Dolby
Digital signal allows for several chan-
nel configurations. Most two-channel
Dolby Digital recordings will allow
the Pro Logic listening mode to be
applied. If the GTP860II detects a
Dolby Digital™ or DTS™ signal it will
be indicated on the front panel dis-
play in the surround mode section.

The GTP-860II is fitted with Bass and
Treble tone controls to adjust the
overall tonality of your system. The
12 o’clock position is ‘flat’ with no
boost or cut and a detent indicates
this position.
Rotate the control clockwise to
increase the amount of Bass or
Treble. Rotate the control counter-
clockwise to decrease the amount
of Bass or Treble. These controls
affect the Left and Right Front chan-
nels. The Tone controls do not affect
recordings made using the Tape or
Video line outputs.

System Connections
Like the front panel, the GTP-860II’s
rear panel is carefully arranged to
make hookup, configuration, and use
as simple as possible. However, the
GTP-860II’s capabilities take some
study to use most effectively. We
strongly suggest that you read this sec-
tion of the manual before beginning
to hook up your system. You will save
yourself much time and effort if you
carefully think out what you expect
from your system: consider the com-
ponents you will use, where they’ll
be placed, and how you will want
them to work together. The diagrams
and notes in this section will probably
answer most of your questions about
interfacing the GTP-860II with other
components in your system.
Note that the GTP-860II’s RCA-style
jacks have color-coded centers to
make connections easier. Use this key
to help route cables properly:
RED centers = RIGHT CHANNEL
ANALOG AUDIO inputs or outputs
WHITE centers = LEFT CHANNEL
ANALOG AUDIO inputs or outputs
YELLOW centers = VIDEO inputs
(composite)
BLACK centers = DIGITAL AUDIO
inputs, CENTER CHANNEL and
SUBWOOFER inputs and outputs
[10] Antenna Connections
AM Antenna: An AM loop antenna is
supplied with the GTP-860II and is
required for AM reception. Open the
clip terminal lever and insert the
wire from the antenna. Closing the
lever will lock the wire in place. Test
various positions for the antenna, but
always ensure the loop is placed verti-
cally for best reception. Placing the
antenna close to large metal items
such as metal shelves or radiators may
interfere with reception.
NOTE: When reception is not satis-
factory using the supplied AM loop
antenna alone, connection of an
external antenna is recommended.
The antenna cable to the loop anten-
na must not exceed three meters.

| ADCOM GTP-860 II Owner’s Manual10
11ADCOM GTP-860 II Owner’s Manual |
FM Antenna: A ribbon wire FM anten-
na is included and should be connect-
ed to the FM connector at the rear
of the unit using the ‘balun’ adapter
supplied. The ribbon aerial should be
mounted on a vertical surface and
placed so that it forms a ‘T’.
Experiment with placement of the
antenna to find the position that
gives the best signal strength and
lowest background noise. An inad-
equate FM signal normally results in
high levels of hiss, especially in ste-
reo, and interference from external
electrical sources. In areas of poor
FM reception, the tuner section’s per-
formance can be improved by using
an externally mounted FM antenna. A
qualified aerial installer will be able
to advise and fit a recommended aer-
ial for your reception conditions.
[11] Preamp Outputs
Before making any connections, check
that the GTP-860II and the power
amplifiers it will be connected to are
switched off. Connect the RCA-to-
RCA leads from the Front Left and
Right, Center, Surround Rear Left and
Right, and Surround Back Left and
Right Preamp Outputs to your external
amplifiers. The subwoofer preamp
output allows for connection to a
sub-bass speaker system with its own
external or integrated power amplifier
(“active” or “powered” subwoofers).
With volume turned down to a low
level, switch power on only after all
connections have been made.
[12] Auxiliary Outputs
The auxiliary outputs allow a line level
connection to various devices, such as
an audio system in another room. The
output is the selected source.
[13] Monitor Outputs
Composite Video and S-Video out-
puts are for connecting a TV or Video
Monitor to view video sources connect-
ed to Video 1 through Video 5. Using
a Video RCA-to-RCA lead or S-Video,
connect the ‘Video Line In’ on the TV
or monitor to the MONITOR OUT.
Note that an S-video input signal
will also be available as a composite
video signal on the Monitor out if
the corresponding source is selected.
Composite video input signals will
also be available as S-Video signals on
the Monitor output.
The video signal available on the S-
Video and Video Composite outputs
is dependent on the selected video
input (Video 1, Video 2, Video 3,
Video 4, Video 5). However, when one
of the audio-only sources is selected
(FM, AM, CD, Tape Monitor or ext
5.1) the last selected video signal
from one of the video inputs will be
present on these outputs. This way
you can watch a DVD player or video
while using the 5.1 analog audio
inputs from a DVD player, as you
might do when listening to a DVD-A or
SACD disc.
[14] Video/Analog Audio
Inputs & Outputs
Apart from the audio signal, these
inputs will also accept a video signal
which will be routed to the Monitor
Out sockets [13] for a television or
video projector. Composite connec-
tion (using the yellow RCA socket) or
an S-Video connection (using the Mini-
Din connector) is available.
The S-Video standard allows for high-
er quality video signal transfer when
compared to the Video Composite
standard. If your video components
have an S-Video connector use dedi-
cated S-Video leads to connect them
to the GTP-860II in the same way as
described with the Video Composite
equivalents.
A video signal fed to an S-Video input
socket will be available on both
the S-Video Monitor Out and Video
Composite Monitor Out.
Video 1 & Video 2: Inputs for the
audio playback and video signal from
a video device such as a stereo TV,
DVD player, satellite cable TV receiver
or a Laser Disc. Using twin RCA-to-RCA
leads, connect to the left and right
‘Audio Out’ of the video device to
these inputs. Using a single RCA-to-
RCA lead (Video Composite) or S-Video
lead, also connect the video output
of the video device. Video 1 & Video
2 can be used for video playback only.
Use Video 3 or Video 4 if you want to
connect a VCR for recording and play-
back through the GTP-860II.
Video 3 & Video 4: Connections for
the audio recording and playback to a
VCR or other video recorder. Using twin
RCA-to-RCA leads, connect to the left
and right ‘Audio Out’ of the VCR to the
Video 3 or Video 4 IN connectors for
playback. Connect the left and right
‘Audio In’ of the VCR to the Video 3
or Video 4 OUT connectors for record-
ing. Using a single RCA-to-RCA (Video
Composite) lead or S-Video lead, also
connect the video output of the VCR to
Video In for Video playback. Connect
the Video Input of the VCR to Video
Out of the GTP-860II preamplifier for
recording of video signals.
[15] Component Video
Inputs & Output
The GTP-860II can switch between
two sources with component video
output. The “video 1” and “video
2” sources have the capabilities to
accept component video signals. Each
component video signal uses three
RCA type connections (Y-green plug,
PB – blue plug, and PR – red plug), all
three connections should be made
for optimum video performance.
Be sure to use high quality video
specific cables for connection. The
Component video connection is inde-
pendent from the S-Video/Composite
video jacks. In order to maximize
signal quality, no On-screen text will
appear on the component outputs.
The “video component output” jacks
should be connected to component
video input on your TV.

[16] Multi-Zone Source
Outputs
These output jacks provide a dupli-
cate of the analog audio signal that
are connected to Video 1-4, CD and
Tape inputs. They are designed to
allow the user to interface the sourc-
es connected to the GTP-860II with
an external stereo receiver or tuner/
preamplifier to facilitate multi-zone
operation. When using the GTP-860II
in conjunction with the GTP-506/
GFA-6006 (a three room stereo tuner-
preamplifier and amplifier combina-
tion) the user can deliver sound to
three additional rooms using the same
source components hooked up to the
GTP-860II. See drawing on next page
(page 13) for details.
[17] Tape Inputs/Outputs
Connections for analog recording and
playback to an audio tape recorder
of any type, such as a cassette, reel-
reel, DAT, MD or CD-R. Using twin
RCA-to-RCA leads, connect to the
left and right ‘Audio Output’ of the
tape machine to the TAPE IN connec-
tors for playback. Connect the left
and right ‘Audio Input’ of the tape
machine to the TAPE OUT connectors
for recording.
[18] CD Analog Inputs
Input for CD player (analog audio sig-
nal) or other line-level signal source.
Use a twin RCA-to-RCA lead to con-
nect the CD player’s left and right
‘Audio Outputs’ to this input.
[19] External 5.1 Analog In
Inputs for the multi-channel audio
signals from an external decoder,
such as an SACD or DVD-Audio player
with integrated decoder. Use two
twin RCA-to-RCA leads to connect the
decoder’s front left and right ‘Audio
Outputs’ to the Front left and right
inputs, and the decoder’s Surround
left and right outputs to the Surround
left and right inputs. Use a third
twin RCA-to-RCA lead to connect the
decoder’s subwoofer output to the
Subwoofer input and the decoder’s
Center channel output to the Center
channel input. Make sure to follow
color coding of the plugs to ensure
that both Center and Subwoofer are
connected correctly; for instance, use
the red plugs at either end to connect
the center channel and the white
plugs for the subwoofer channel.
[20] Digital Audio Inputs
Use these inputs to connect the
coaxial and optical digital audio signal
output from such digital devices as
CD, DVD or LD players. These inputs
are fully assignable using the OSD.
[21] AC Power Cord
After you have completed all connec-
tions to the amplifier, plug the AC line
cord into a “live” wall socket.
[22] 12V DC Trigger
To facilitate remote turn-on and
turn-off of other components (power
amplifiers, for example), this 3.5mm
mini-jack provides a constant signal
(12 volts DC) whenever the GTP-860II
is fully powered. When the GTP-860II
is turned off (via the front panel
switch) or placed in standby mode (via
the “power” button on the remote
control), the jack has no output.
[23] Voltage Switch
The GTP-860II can be configured for
either 120V or 230V operation using
this switch. Extreme caution must
be used when changing the voltage
of the unit, as an incorrect voltage
selection will cause severe damage to
the unit. See your dealer or contact
ADCOM for more details regarding the
operation of this switch.
NOTE: We strongly recommend the
use of our surge suppressor/ line con-
ditioners, the ADCOM ACE family of
products, for systems with substantial
amplifiers and many source compo-
nents. The ACE products relieve the
GTP-860II from handling large current
surges, while they protect your entire
system by filtering and conditioning
the AC current. In addition to the
numerous heavy duty AC outlets of
the ACE-315, the ACE-615 includes
sequential power-up and power-down
modes to minimize “thumps” when-
ever you turn your system on or off.
[24] IR Input
The IR input allows hook up of an
external IR sensor that sends IR infor-
mation to the microprocessor in the
GTP-860II. This feature can be very
useful if the GTP-860II is placed
behind a non transparent door or is
used with an after market remote con-
trol system.
[25] RS232 Control (dB 9)
Allows control of the GTP-860II via
computer or home automation system.

The drawing above illustrates the
proper hook-up to provide audio to
multiple zones using a signal source
with the GTP-860II. As illustrated
above we use a GTP-506 and GFA-

2.1 GRC-800 Overview
The GRC-800 remote control is a
learning remote control that is
capable of saving commands for all
remote controls in your home theater
system. In this way, you may elimi-
nate the confusion of using multiple
remotes. Although such power comes
with some added complexity, the
complexity is minimal and with some
repetition will become second nature.
Eight Source Select Buttons
The single most important aspect to
master about the GRC-800 remote
control is the function of the eight
source select buttons at the top of
the remote. These are the buttons
labeled [53] and [26] in the figure
on the opposite page. Each of these
buttons cause two things to happen
when used. First, they select the cor-
responding input on the GTP-860II.
Second, THESE KEYS REMAP ALL OF
THE OTHER BUTTONS ON THE REMOTE
CONTROL. You can think of each of
these buttons as having a page of
commands associated with it. Some
buttons, such as volume up and down,
are pre programmed to operate the
GTP-860II for each source. These
buttons can be “written over” if you
like, but default to GTP-860II opera-
tions for your convenience.
Most of the GTP-860II remote com-
mands are saved under the main
remote page. Whenever you desire
to control the GTP-860II via remote,
you must first ensure the main page is
active. As an example, press [53] main
on the remote control. Now, press
the dim button. If your GTP-860II is
on, the brightness of the front panel
display changes. Notice also that the
main button on your remote illumi-
nates. This serves as a reminder that
the main remote page is currently
active. Now press the CD button and
then the play button. Notice now
that the CD source button lights. The
CD remote page is now active. If you
have an ADCOM CD player, this com-
mand will cause an idle CD to play.
Now, press the dim button again. You
should note that CD button does not
light. The dim command is not pre
programmed in the CD remote page.
If your GTP-860II is on you will also
notice the display does not respond
to this command. Press the [53] main
button again to reenter the main
remote page. The dim button will now
again change the GTP-860II display.
The button description that follows
distinguishes the function of each
button dependent on the page the
remote is in. The remote is shipped
from the factory with ADCOM com-
mands saved under the main, tuner,
and CD pages, and with important
GTP-860II functions such as volume
saved under each page.
The ADCOM universal remote control-
ler is preset to operate all GTP-860II
functions (MAIN and TUNER device
mode) and most GCD-700/750 CD
functions (CD device mode).
Alkaline batteries are recommended
for maximum operating life. Four AAA
(R 03) batteries should be fitted in
the battery compartment at the rear
of the remote control. When replac-
ing batteries, check that they have
been put in correctly, as indicated on
the base of the battery compartment.
Remote Features
[26] Source Selectors (vid
1, vid 2, vid 3, vid 4, vid 5, tuner,
CD):
These buttons serve two functions.
• First, they switch inputs on the
GTP-860II so you can hear the source
you’ve just selected.
• Second (and even more important),
they can change the functions of
all the other buttons on the remote
controller. In other words, if you
first push the CD device selector, the
remote’s play button generates a
command code for your DVD player.
If you then press the vid 5 device
selector, the same play button would
send a different command code
that might, for example, start your
mini-disc player. (Of course, this all
depends on how you programmed the
remote in the first place. This will be
covered shortly.)
[27] Power Button
In all modes, this is pre programmed
to turn the GTP-860II on and off.
[28] Input Selector
In main mode, these are similar to
the source selectors described above
but they switch only GTP-860II inputs.
They DO NOT automatically change
the functions of other remote buttons.
[29] Mute Button
In all modes, this button is pre pro-
grammed to mute outputs of device.
Mute does not affect recordings
made using the Tape outputs but will
affect the signal going to the Preamp
Outputs. When the unit is in mute
mode, any adjustment of the Volume
Control on the front panel [4] will
release the muting, i.e. the original
volume level will be resumed.
[30] Dynamic Range
In main mode, this button is pre pro-
grammed to adjust dynamic range of
Dolby Digital encoded sources.
The d. range button, which can be
used only in combination with a Dolby
Digital source, incrementally reduces
the audio track’s dynamic range in
four steps (100%, 75%, 50% and 25%)
to allow for comfortable listening
under a variety of conditions. The
normal or default position is 100%. To
adjust the dynamic range, each con-
secutive press of the d. range button
will reduce the value in 25%
increments, as shown in the alpha-
numeric display section.
Although we usually prefer to repro-
duce a source’s full dynamic range
(the difference between very loud
and very soft sounds), it may occa-
sionally be desirable to reduce the
dynamic range. For example, when
playing a movie late at night, loud

| ADCOM GTP-860 II Owner’s Manual16
17ADCOM GTP-860 II Owner’s Manual |
explosions might wake sleeping family
members. Simply turning the volume
control down would probably make a
whisper in the next scene inaudible.
The d. range button solves this dilem-
ma by progressively lowering the
volume of loud peaks while increasing
the level of softer sounds.
[31] Volume Up/Down
In all modes, these buttons change
the master volume setting of the
GTP-860II. In all modes except main,
they can be reprogrammed with new
commands. The Volume control does
not affect recordings made using the
Tape and Video, or Tape, Video 3 and
Video 4 outputs but will affect the
signal going to the Preamp output.
[32] Mode Button
In main mode, this is pre programmed
to cycle through the surround modes
of the GTP-860II. Pressing repeatedly
will cycle through Pro Logic, Hall,
and Stereo, when available. Refer to
the Surround Mode description [8] for
more information.
[33] Play Button
In CD mode, it is pre programmed for
play with an ADCOM CD player.
[34] Pause Button
In CD mode, it is pre programmed to
pause an ADCOM CD player.
[35] Stop Button
In CD mode, it is pre programmed to
stop an ADCOM CD player.
[36] Arrow Buttons
The arrow buttons allow navigation
throughout the GTP-860II OSD (On
Screen Display) menus (as well as
the menus of other devices, once the
commands are learned). Please refer
to section 3.1 for further explanations
on the OSD.
Left arrow: In main mode, this is pre
programmed to step through the vari-
ous choices you might wish to select
while a menu item is highlighted.
In CD mode, it is pre programmed for
audible reverse scan with an ADCOM
CD player.
Up arrow/Setup: In main mode, this
is pre programmed to enter the OSD
menu system, as well as scroll up to
the next choice on a menu screen.
Right arrow: In main mode, this is
pre programmed to step through
the various choices you might wish
to select while a menu item is high-
lighted.
In CD mode, it is pre programmed for
audible forward scan with an ADCOM
CD player.
Down arrow: In main mode, this is
pre programmed to scroll down to the
next choice on a menu screen.
[37] Select Button
In main mode, this is pre programmed
to enter a selection chosen via the
menu system.
[38] Direct Access Keys
(buttons “1” through “10,” and
“+10”): In CD mode, buttons are pre
programmed as track access com-
mands for the ADCOM CD player.
[39] Test Button
Pressing the test button engages the
test signal generator. The test signal
cycles through the activated channel-
sautomatically with 3-second intervals
from Front Left, Center, Front Right,
Rear Right, Back Right, Back Left,
Rear Left, to Subwoofer in continuous
cycles. Press the test button again
to turn of the test signal. You can
make adjustments to channel balance
with the test tone generator using the
Channel Test section of the On Screen
Display setup menus.
[40] Bal (balance) Button
In main mode, this button is pre pro-
grammed to initiate balance check
procedure. Even when the GTP-860II
is correctly set-up, it may sometimes
be desirable to make minor adjust-
ments to suit the material you are
listening to. Pressing the bal button
allows for direct adjustment of all
active channels. Use the up and down
arrow buttons to select the channel
you wish to adjust and the left and
right arrows to modify the level. Both
the front panel display and the OSD
show the current status of adjust-
ments. Press the Bal button a second
time to exit this function, the new
levels will automatically be saved.
[41] Backs Button
In all modes, this button is pre pro-
grammed to toggle on and off the
Surround Back speakers.
[42] Repeat Button
In CD mode, this button is pre pro-
grammed as “repeat” command for
ADCOM CD player.
[43] Random Button
In CD mode, this button is pre pro-
grammed as “random” command for
ADCOM CD player.
[44] Tuning Up/Down
In tuner mode, these buttons are pre
programmed to scan up or down the
GTP-860II’s AM or FM band.
[45] Pre/Tune Button
In main and tuner modes, this button
toggles between manual tuning and
preset station functions for the tuning
up and down buttons [43].
[46] RDS Button
This button selects the type of RDS
information that will be displayed
when it is available from the currently
selected radio station. The PTY mode
will indicate program material type
such as jazz or rock or classical. The
call mode will usually dispaly the call
letters of the station (WXYZ), but may
also include additional information

2.2 Remote Function Table
This table supplements the infor-
mation you’ve just read. Use it to
quickly review button functions. The
controller’s capabilities are extensive
and may be somewhat intimidating at
first. However, you will soon find that
its logical button arrangement and
programming capabilities will greatly
increase your enjoyment as you dis-
cover the ease with which you can
operate your entire system from just
one remote!
Look down the left-hand column until
you see the button you want to learn
about. Then look under MAIN to see
if it is pre programmed for a GTP-
860II function, under CD to see what
CD commands are pre programmed,
and under TUNER to see all pre pro-
grammed tuning functions.
NOTES: Direct sunlight or very bright
ambient lighting may affect the oper-
ating range and angle for the remote
control handset.
The infrared remote control command
receiver, located to the right of the
Power button, receives commands
from the remote control. There must
be a clear line-of-sight path from the
remote control to this window; if that
path is obstructed, the remote con-
trol may not work.

2.3 Programming Your
ADCOM GRC-800 Remote
The ADCOM universal remote control-
ler operates eight different audio/
video components. As you’ve already
seen, it’s pre programmed to control
ADCOM’s GTP-860II Preamp/Tuner
and the GCD-700/750 CD players. In
addition, it has seven “component
memory banks” available so you can
program the remote to learn com-
mands for your DVD player, satellite
box, laser disc player, VCR, etc. This
lets you use one remote controller for
your entire system.
Using Pre programmed Commands
Using the remote controller’s pre
programmed commands is simple.
For most GTP-860II functions (volume
up/down, changing surround modes,
etc.), follow these easy steps.
1. Press the main source selector
button. This tells the remote that
you want to use GTP-860II pre pro-
grammed commands. The main button
will flash red to tell you it under-
stands.
2. Press the appropriate function but-
ton (volume up, volume down, etc.)
If you’ve selected a button that actu-
ally triggers a GTP-860II command,
the main button will again flash red to
confirm your choice. If the main button
does not flash, you’ve selected a func-
tion button that isn’t pre programmed.
For tuner functions (changing
stations, etc.):
1. Press the tuner source selector
button. It will flash red.
2. Press the tuning up (or tuning
down) function button to change sta-
tions. The tuner source selector will
flash red to confirm that the func-
tion button you’ve selected actually
triggers a command. (Again, use the
table to see which buttons are pre
programmed.)
Press the CD source selector first to
access pre programmed commands for
ADCOM CD players.
NOTE: You can program new com-
mands over the pre programmed com-
mands in tuner and CD if you wish.
However, you cannot program any
buttons, even those unprogrammed
with GTP-860II command codes, while
you’re in main mode. This safety fea-
ture assures you that you will always
be able to fully enjoy the GTP-860II’s
capabilities.
Programming Your Own Commands
You can supplement pre programmed
commands with commands to oper-
ate other components. Before you
begin to follow these steps, note the
status LED located at the top left
corner just above the remote’s but-
ton panel: It will flash red, orange,
or green to signal particular functions
as you enter new commands into your
ADCOM remote.
Begin by deciding which source com-
ponent’s commands you will be trans-
ferring to the ADCOM remote. Then
press the appropriate source selector
button. For example, if you’re teach-
ing your ADCOM remote commands for
your Video 1 source, press the vid 1
source selector first. You can “teach”
your remote new commands for any
function button (except backlight)
after you’ve selected vid 1, vid 2, vid
3, vid 4, vid 5, tuner, or CD.
1. Place the source component’s
remote “head to head” with the
ADCOM remote. They should be in
line with each other about 2 to 3
inches apart.
2. Press the ADCOM remote’s appro-
priate source selector and select but-
tons simultaneously. Hold both but-
tons until the status LED turns orange
and the source selector button glows
red. Both indicators should remain lit.
3. Decide which function button on
the ADCOM remote you want to learn
a new command. Press it. The orange
status LED will begin to flash and the
source selector LED will go out.
4. Find the corresponding button on
the source component’s remote. Press
and hold it until the status LED on
the ADCOM remote flashes green once
and remains green until the button on
the source remote is released. Once
the button on the source remote is
released, the status LED will start
flashing orange again.
5. Verify that the ADCOM remote has
learned the new command by pressing
and holding the same button on the
source remote. The ADCOM remote’s
status LED should flash green twice
and then go back to steady orange.
This indicates successful program-
ming. Release the button on the
source remote.
Repeat Steps 3 through 5 for any
other commands you want to teach
your ADCOM remote for that source
component.
Save the commands you’ve just pro-
grammed into the ADCOM remote by
pressing and holding the appropriate
source selector and select buttons
simultaneously. Hold until the status
LED and source selector LED flash
twice and then go out. Repeat these
steps for any other source commands
you wish to program.
Deleting (Clearing) Individual
Programmed Commands
1. Press the ADCOM remote’s source
selector and select buttons simultane-
ously and hold until the orange status
LED and the source selector button
glow steadily.
2. Press the function button you wish
to clear. The status LED will flash
continuously.
3. Press the backlight button. The
status LED will then flash green twice
and then revert to steady orange. The
source selector button will continue
to glow.
Repeat steps 2 and 3 for any other
command you wish to delete for the
same source component.
