future reference.
HEED WARNING - All warnings on the appliances and in the operating
instructions should be adhered to.
.
FOLLOW INSTRUCTIONS - All operating and use instructions should be
followed.
WATER AND MOISTURE - The appliances should not be used near water - for
example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet
basement, or near a swimming pool, etc.
LOCATION - The appliances should be installed in a stable location.
WALL OR CEILING MOUNT - The appliances should not be mounted to a wall
or ceiling.
VENTILATION - The appliances should be situated so that their location or
position does not interfere with their proper ventilation. For example, the
appliances should not be situated on a bed, sofa, rug or similar surface
that may block the ventilation openings.
HEAT - The appliances should be situated away from heat sources such as
radiators, heat registers, stoves, or other appliances that produce heat.
POWER SOURCES - The appliances should be connected to a power supply
only of the type described in the operating instructions or as marked on
the appliances.
GROUNDING - Make sure that the units in the system are always connected
to a standard three-prong grounded outlet (the circular pin is ground).
When operating this unit at a higher voltage with a different power cord
configuration, consult your dealer for the proper power cord/outlet com-
bination to use before operating this unit.
POWER CORD PROTECTION - Power supply cords should be routed so that
they are not likely to be walked on or pinched by items placed upon or
against them, paying particular attention to cords at plugs, convenience
receptacles, and the points where they exit from the appliances.
CLEANING - The appliances should be cleaned only with a polishing cloth or
a soft dry cloth. Never clean with furniture wax, benzine, insecticides or
other volatile liquids since they may corrode the face plates.
POWER LINES - An outdoor antenna should be located away from power lines.
PERIODS OF DISUSE - The power cord of the appliances should be unplugged
from the outlet when the units are not in use for a long period of time.
OBJECT AND LIQUID ENTRY - Care should be taken so that objects do not
fall and liquids are not spilled into the enclosures through openings.
DAMAGE REQUIRING SERVICE - The appliances should be serviced by an
authorized service center or qualified service personnel when:
• The power supply cords or plugs have been damaged; or
• Objects have fallen, or liquid has been spilled into the
appliances; or
• The appliances have been exposed to rain; or
• The appliances do not appear to operate normally or
exhibit a marked change in performance; or
• The appliances have been dropped; or the enclosures have
been damaged.
SERVICING - The user should not attempt to service the appliances beyond that
described in the operating instructions. For all other servicing, contact the
factory.
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRI-
CAL SHOCK, DO NOT EXPOSE THE APPLI-
ANCES IN THIS SYSTEM TO RAIN OR MOIS-
TURE. REPLACE FUSE ONLY AS MARKED.
CAUTION:
TO PREVENT ELECTRIC SHOCK, DO NOT
PLUG THE UNITS IN THIS SYSTEM INTO ANY
OUTLET OR EXTENSION CORD WITHOUT THE
STANDARD THREE-PRONG CONFIGURA-
TION, WHERE THE CIRCULAR HOLE IS USED
FOR THE GROUND PLUG.
IMPORTANT:
The exclamation point within the equi-
lateral triangle is intended to alert the
user of the presence of important op-
erating and maintenance (servicing)
instructions in the literature accompa-
nying the appliances.
CAUTION:
TO PREVENT RISK OF ELECTRICAL SHOCK, DO NOT
REMOVE COVER (OR BACK). NO USER-SERVICEABLE
PARTS ARE INSIDE ANY OF THE UNITS IN THIS SYSTEM.
REFER SERVICING TO QUALIFIED SERVICE PERSON-
NEL.
The lightning flash with the arrowhead,

HTR-2400 REAR PANEL CONNECTIONS
To ensure that proper connections are maintained, wire management needs to be consid-
ered. It is recommended that wires and cables be fastened in such a way that as much of
their weight as possible be secured to something other than the actual connector or jack on
the HTR-2400. For pull out racks, make certain that there is enough room behind the rack to
permit the wires and cables to retract without pinching, pulling or crunching.
TUNER CONNECTIONS
The HTR-2400 features two tuner modules. At
the time of this printing, the modules available
are an XM Radio Module and an FM/AM/WX
(Weatherband) radio module. These modules,
like all of the HTR-2400’s rear-panel assembly,
are cards that slide in and out of the chassis on
tracks. As such, they can be updated or re-
moved.
The tuner modules feature an antenna input and
a stereo audio output. In order to hear the out-
put of these tuners, you need to loop this audio
output to inputs on the HTR-2400. Typically, you
will loop Tuner Module one (far left side of rear
panel) to Audio Input 1 and Tuner Module 2 to
Audio Input 2 as show to the right.

When installing the HTR-2400, you will need to connect audio and video sources for the
home and theater, digital sources and S-Video/Component video for the theater, antenna
connections for the tuners, AC and IR source connections, keypads, perhaps RS-232, speaker
lines for the house, speaker lines for the theater, perhaps line-level theater outputs, low-
voltage triggers for theater, and record analog, digital and S-Video outputs.

(or other FM Antenna)
For basic antenna connec-
tions, one can run the radio
antenna directly into the HTR-
2400’s FM/AM/WX Module.
Please note, that in order to get
both FM and AM, you will need to provide the re-
quired antennas and combining components. The
XM Antenna, provided with the HTR-2400 can be
connected to the HTR-2400. Again, placement of
the XM antenna needs to be in such a manner that XM Radio reception is possible.
ADA also provides the ACB Antenna Combiner Boxes (ACB-1 and ACB-2) which take both
the FM antenna, AM antenna, and XM antenna and combine these signals on a single RG-6
type coax cable. This cable can be run up to 200 feet to the HTR-2400’s equipment rack. The
ACB-1 and ACB-2 are sold as a set and the AML-1 AM Loop Antenna is sold separately.

Because the HTR-2400 is actually two system in
one, it is important to remember that the analog
sources that play in the house can also play in
the theater while the digital sources that play in
the theater will not play in the house. As such,
some sources will require two audio connections.
For example, a DVD player will require an ana-
log audio connection for playback in the house
while the theater will require a digital audio con-
nection for playback of 5.1 encoded material. The
theater connections will be discussed later.
The HTR-2400’s out of the box source setup is:
Even if you are not distributing composite video
throughout the house, you will still want to con-
nect the sources’ composite video outputs to the
HTR-2400. Because the front panel 16 x 9 color
LCD display only runs composite video, in order
to preview images on this display, the HTR-2400
must receive a composite video signal.

The Home Theater source setup is more flexible
than the multi-room system. The multi-room
audio and video jacks are linked together numeri-
cally (audio input 1 tracks video input 1, audio
input 2 tracks video input 2, etc.). For the Home
Theater, the source names (input names) can
be openly assigned to any audio jack (analog or
digital), composite video, S-Video, and compo-
nent video input. This makes it easy to both cus-
tomize the HTR-2400 to your particular installa-
tion and maximize your inputs.
While the HTR-2400’s out of the box setup (as
shown in the chart to the right) shows for 20 in-
put labels, note that several use the same jacks.

6 CHANNEL DVD AUDIO INPUT
Because you can limit the number of inputs dis-
played, rename the source names, reassign
jacks, this setup serves only as an example of
what can be done and corresponds to the HTR-
2400’s out of the box factory default setup.
For digital audio sources, if coax type connec-
tions are available, ADA suggests using these
over TOS-Link connectors. When using TOS-
Link interconnects ADA suggests using the best
caliber cable available (frosted tip or convex tip).
TOS-Link cables have been known to reflect
against the TOS-Link receiver causing for audio
dropouts. Better cables help prevent this.
For DVD Audio discrete 5.1 playback, a six-chan-
nel analog bypass input is used on the HTR-
2400. Please note, that in order to access this
input, you will need to select a source name that
is not used, relabel it to read DVD AUDIO, and
assign the audio input to ANALOG BYPAS.
Because the HTR-2400’s Home Theater has
open input assignment, it can use open (or un-
used) composite video inputs. In a common
setup, house inputs 1-4 are used by the tuners
and CD players and these devices typically do
not output any video. As such, the Home The-
ater can use these video inputs for theater spe-
cific sources like a DVR, VCR or Laser Disc
player.
The S-Video switcher of the HTR-2400 permits
four S-Video signals to be routed to two outputs.
Both outputs play the same signal. Please note
that an S-Video input only comes out of an S-
Video output.
The component video switcher of the HTR-2400
permits three component video signals to be
routed to one component video output. The com-
ponent video output only routes component video
inputs. If you wish to view composite or S-Video
sources on your display, you will need to con-
nect both composite video, S-Video and compo-
nent video from the HTR-2400 to your display
device.

The HTR-2400 provides class D (digital) power
amplification for the eight rooms in the house.
Each zone output is stable down to 2 Ohms but
best performance will be achieved when operat-
ing speaker loads in the 8-4 Ohm range. The
room amplifier channels are bridged. This means
that the ground (-) is unique to the left and right
channels. You cannot short the grounds together
because they are not common. Because of the
close proximity of all speaker outputs, pay close
attention to cleanly terminate speaker wires.
Each zone also has a composite video
output. These can be used to provide
video to local TVs or video capable
touch-screens.
Room 1 shares its video output with
Home Theater zone. If any of the Home
Theater sources have their composite
video active (set to ON), even if that
source is not selected, then as Room 1 selects a source, video will not follow. However if the
Home Theater is only being driven by S-Video or component video and all home theater
sources have composite video set to OFF, then when an input is selected for Room 1, the
video will follow. This feature permits you to determine if Room 1 is a video capable zone or
not. For a flexible Home Theater setup, ADA suggests assigning Room 1 to a zone that does
not have a video display.

The HTR-2400 also features line-level audio outputs for the home theater zone. In many
cases, while you may be using the power amplifier in the HTR-2400 for all of the theater’s
speakers, you may need to use its line-level audio outputs for connection to a self-powered
(active) subwoofer. Alternately, you can connect additional power amplifiers or a multi-chan-
nel power amplifier to the HTR-2400.

In the event that you are using an external power
amplifier in the Home Theater, the HTR-2400
features a low-voltage trigger output (12VDC)
that can be used to trigger an ADA power ampli-
fier. Using a 2-conductor low-voltage wire, con-
nect the HTR-2400 trigger to the trigger input on
the ADA power amplifier (set the amplifier Trig-
ger Switch accordingly). You will also need to
set the DC Trigger to ON when programming the
HTR-2400 Theater Sources.
The HTR-2400 video
outputs connect to the
Theater’s video display.
The extra S-Video out-
put can connect to a
recording device.

devices. The analog output only passes analog
sources and the digital output only passes digi-
tal sources.

IR LEARNER - CONNECTIONS & FEATURES
The HTR-2400 features an internal
eight source IR Learner that is based
on ADA’s IRL-5000. The latter sec-
tion of this manual discusses the pro-
gramming of the IRL. The diagram
to the right shows the out of the box
setup of the HTR-2400. Ports can be
reassigned during the HTR-2400
setup to suit your custom installation.
The IRL can be removed to alter IR port operation or to even program the IRL in the shop
while the HTR-2400 chassis begins to be installed. To do this, simply connect a 12VDC
500mA power supply to the IRL board to program the IRL outside of the HTR-2400 chassis.
There are three types of jumper pin settings; IR Flasher, IR Repeating, and Serial Data Con-
trol. The IR Flasher jumper pins are a group of eight jumper pins together. The out of the
box setup has these jumper pins offset (un-shunted) so the pins are there but simply not in
place. When these pins are offset (not in place, un-shunted), the port they reference are set
to use an IR flasher (emitter). When the jumper pin is in place (shunted), the port is set for
serial data control with the IR carrier stripped out.
The other two types of jumper pins are grouped by port number. The IR Repeating jumper
pin determines if the port will pass IR that comes down the ADA Bus from IR receivers located
in keypads (or the IRR-5000). To defeat IR repeating entirely for a port, remove or offset the
jumper pin. If you require IR repeating, set the jumper pin to the appropriate position (IR
flasher or serial connection {no IR carrier}). If the IRL is working from the PC program’s
Simulator but not from the keypads, and the keypads have been programmed to track
the appropriate IRL ports, then turn IR repeating OFF by offsetting (removing) the IR
repeating jumpers. REASON - When a keypad issues a transport command, the RS-232 code for the IRL
is sent down the ADA Bus to the IRL so that it can then issue the source’s IR command. If repeating is on, the
keypad’s command first emits through the IR flasher. If the source component’s IR receiver is slow to cool down
(so that it can take the next IR command), when the IRL releases the actual command (a moment later), the
source component’s IR receiver may reject it. By turning off IR repeating, only the IRL source function is sent.
The last jumper pin is the Serial Data Control jumper pin which is only used if you are
connecting to a source component’s rear panel serial data connection. Here you can opt to
send the serial data in the nor-
mal (Norm) position or inverted
(Invert) position.
There is also an IR Repeater
Frequency trim pot that ad-
justs the IR carrier frequency for
IR repeating only. This pot has
no effect with keypad control.

ADA keypads connect directly to the HTR-
2400’s eight RJ-45 female connectors. The
suggested wire is standard Cat. 5 cable.
Wiring is the most critical aspect of an ADA
installation. ADA keypads wire straight-
through (no crisscross). Make certain that
your wiring is free of error or damage prior
to connecting keypads! The diagram and
chart to the right show a typical Cat. 5 to RJ-
45 connection. Your color code may vary but
it is critical that point to point connections be
in tact.
If you need to connect additional ADA key-
pads, please contact ADA as to the best re-
sult based on the number of extra keypads
needed. The HTR-2400’s ADA Bus jack can-
not simply connect to another ADA wire har-
ness (i.e. WH-2000) and then to more key-
pads because the power supply on the ADA
Bus jack is not designed to drive keypads. In
order for this to function, an additional power-
supply will most likely be required.
In the event your Cat. 5 cable is damaged,
you can still get full operation by leaving off
both pins 1 & 8 (leave both wires off even if
you have 7 good Cat. 5 wires).

SELECT MENU OFF
FRONT PANEL CONTROL
The HTR-2400’s easy to use front panel permits
you to control the entire home. The buttons flank-
ing the LCD display are source transport func-
tions (source control). How these operate will
depend on how your custom installation profes-
sional programmed the HTR-2400’s infrared
learner (IRL). Because the two tuners are inter-
nal to the HTR-2400 and are not controlled by
the IRL, their operation is explained below.
To the left of the color LCD display
are numeric source transport but-
tons including * and Enter. There is
also the black Master Power switch
located to the far left of the bezel.
The right side of the display fea-
tures additional source transport
buttons including play, stop,
pause, reverse play, forward, re-
wind and navigation buttons.
The Master Power switch needs to be pushed in for the HTR-2400 to operate. When servic-
ing the system, it is wise to turn this button off. Turning the button off is similar to unplugging
the HTR-2400.

Just like source selection, the HTR-2400
permits you scroll through the available
modes without actually making the change
until the desired mode is displayed in area
“D”. The current mode will remain on the
display in area “C” until the switch is en-
acted. To change the mode, press the
Mode knob.
Note, because the HTR-2400’s DSP (digital signal processor - the home theater’s brain) is
“auto-sensing”, it will only display modes that can be used. For example, when playing back
a 5.1 channel encoded DVD, only “Cinema Modes” will appear as you turn the Mode knob.
When playing back a normal CD in the DVD player, only “2 Channel” modes will appear.
Adjusting Volume
The volume in the Theater Zone can be raised
or lowered using the Volume knob.
Muting Volume
To mute the volume in the Theater Zone, press
the Off button. To unmute, press the Off button
again or give the Volume knob a slight turn.
Turning the Theater Zone Off
Press and hold the Off button to turn the Theater
Zone off. Please note, that this will not perform
an All Off function for the other eight rooms on
the system. The Theater Zone operates inde-
pendently from the rest of the home with respect
to all off.

Tone Presets
The Theater Zone has four Tone Presets. This
is actually a complex feature set of the HTR-
2400. Tone Presets permit the installer to cre-
ate two groups of speakers (A and B). Each
grouping can have an independent bass fre-
quency point, bass level, treble frequency point,
and treble level. These features are used for
room equalization.
To recall a Tone Preset, press the Volume knob
so that the flashing * (cursor) is on TONE RE-
CALL #. Turning the Volume knob will allow you
to select one of the four Tone Presets. Preset
recall is immediate and will occur a second after
the tone preset number is displayed.
Balance Presets
Balance presets contain both levels and delay
settings of all speakers in your theater. This per-
mits your installer to optimize the sound in the
theater for multiple seating positions (hot spots).
Please note, that in order for this feature to work,
you must have stored Balance Presets.
To recall a Balance Preset, press the Volume
knob so that the flashing * (cursor) is on BAL
RECALL #. Then turn the Volume knob until the
desired preset number is displayed. Preset re-
call is immediate and will occur a second after
the balance preset number is displayed.
Volume Presets
Volume presets contain the master volume level
of the theater. Your custom installation profes-
sional will have had to store these presets if you
wish to use this feature as intended. There are
four Volume Presets permitting you to perhaps
set up a low, medium, high and super demo level.
To recall a preset, press the Volume knob until
the * is flashing on VOL RECALL. Then turn the
Volume knob to select the preset number. Pre-
set recall is immediate and will occur a second
after the balance preset number is displayed.

and what source is playing to it.
On this page you can:
1Select a room.

vance downward to the next room with each
press of the Room knob.
