INTRODUCTION
The Model 903 Control Panels connect to the Access™ Demonstration Network switching
system to show the products currently selected to play and to provide an easy method of
controlling the display to select products, store and recall systems, and activate special
features. The panel controls are divided into two functional sections - a selection keypad and
a Product Group selection. See the illustration below.
Please read and follow these instructions carefully. If you have any difculties during the installation, don’t hesitate
to call us for assistance! We’re open Monday through Friday from 8:30 AM until 5:00 PM, Eastern Time. Also check our
website for diagrams and tips: audioauthority.com/access_tips.
The Selection Keypad includes:
• 0 – 9 numeric keypad
• UP and DOWN arrow keys for scrolling through selections
• A/B/C comparison keys for easy system comparison
• SECURE key for accessing various secure modes and system features
• SilenTouch™ circuit indicator
• Infrared remote receiver window
The Product Group Section includes the following for each of the 8 Product Groups:
• A Select key for activating each Product Group
• A LED indicator that illuminates when each Product Group is Selected
• A 2-digit display that shows the number of the ACTIVE component
• An ID window for slide-in Product Group labels
In addition to the 903 Control Panel, the Access™ System can also be operated by:
• Product Select Buttons - push-button located next to each product
• IR Remote Control - Download IR codes from website
• By using a computer touchscreen with custom software congured to enable product selections
and other control functions

One unique characteristic of the Access System is that all of these different modes of product selection may be used in
the same system. This means that your system could contain a Control Panel, an IR Remote, and Product Select Buttons,
as well as an external computer touchscreen. So, it is important for you to be familiar with your system and know the
different modes of access (input) to your system.
Model 903 Control Panel - Rear View
Conguring the Control Panel
On the back of the Control Panel is a bank of Conguration DIP Switches that enable or disable certain functions. These
switch settings should have been adjusted to match your merchandising requirements during the installation, however,
they may be changed at any time. The following chart details the function of each switch.

INSTALLING A CONTROL PANEL
Preparation
A.Cut an opening for the Control Panel if you wish to ush mount it in your
display or other surface.
• For a 903 Control Panel, cut an opening 7” (178 mm) wide by
5-1⁄8” (130 mm) high.
• Use the panel to mark screw hole locations and drill 7⁄64” (2.5
mm) holes for the screws.
• Insert the appropriate slide-in Product Group labels provided with a 903 control panel into the product group
display windows to identify each component group on the panel. Consult page 6 of your 903 User’s Guide for
more information on Product Group labeling.
Note: The 903 Control Panel can also be remotely controlled using a third party IR remote programmed with the IR codes avail-
able at audioauthority.com/access_tips.
B. Using the ten foot cables supplied, plug the 903 into the 980 System Module at the header marked 903 (Figure 3).
C. Set the Conguration Switches on the control panel (See Switch Settings on page 5.)
D. Mount the control panel using the four screws provided. Do not overtighten the screws.
Testing SYSTEM Function
903 Test Sequence
Test the Control Panel. Reboot the system (press Secure, 88, Secure) and
observe the following test results on the Control Panel. If you encounter
any problems, keep a note pad handy to record results as they are
reported in the Control Panel windows.
1. All display segments and indicators on the control panel are lit briey
(lamp test).
2. The Info Display at the left of the panel shows software version
(e.g., 3.4).
3. A System Bus Test is performed.
a. If the word “bUS” ashes in the Info display, it indicates a
problem with a system bus cable or switching module.
b. To nd the faulty cable or module, use this process of
elimination: carefully unplug portions of the yellow-red-blue-black system bus cable to isolate them from the
980 module, then press any key on the control panel. If “bUS” still appears on the Info Display, plug the cable
back in and try a different cable.
c. If “bUS” disappears from the Info Display, you have isolated the module or bus cable that is faulty.
Re-address the module and cycle power or replace the cable.
d. Call Audio Authority®Technical Service at 800-322-8346 for assistance with parts replacement.
4. After the bus test, the diagnostic program scans the active range of module addresses in every Product Group. You
will observe these module addresses counting up in the Info Display as the product group number is displayed in each
group’s Product Group window. Lowest group numbers rst, and electronics groups come up before speaker groups
(e.g., 922, 942, 945, 955, 956, (all electronics), 932, 939, (speakers).
Figure 4.
Info Display PG Window
Figure 3.

7
If the numeric displays begin ashing during the module scan, then two or more modules have the same address.
Duplicate addresses are disallowed because the control panel is unable to tell two identically addressed modules apart
unless they are left and right modules in a stereo pair.
a. Make a note of the last group number displayed in the Product Group windows and the module number
shown in the Info Display nd the two modules that both have this address. For example, if the control panel
is ashing, the Info Display shows 002, and the third Product Group window shows S4, you would look for
two speaker modules (932) with the same address of “Group 4, Module 02, Right.”
b. Remember that pairs of speaker modules must have the same Group and Module ID address, but must be
identied Left and Right to avoid a duplication.
c. If the problem address disappears too quickly to write down, press SECURE, 88, SECURE to reboot the
system and repeat the test.
d. As each new group number appears in a PG window (Product Group, Figure 4), the Info Display counts up
the number of modules in that group that can be recognized. Write down the highest number reported in the
Info Display and the Group number with it. For each group, compare the reported module tally with a physical
count of the modules.
e. If the module count in a group does not match the number
of modules you actually have, look for disconnected or
mis-addressed modules. For example in a system has four “E
Group 0” modules, four “E Group 4” modules, and three pairs
of “S Group 4” modules.
1.The top PG window displays “E0” as Info Display
scans up to 4 (good).
2.The second PG window displays “E4” as Info Display
scans up to 5 (bad)
3. The third PG window (shown in Figure 5) displays
“S4” as Info Display scans up to 3 (good.)
In this case you would look for a mis-addressed, unplugged,
or faulty E4 module (Electronics Group 4.)
f. Also check for gaps in the series of Module ID settings in that
group. For example, 0, 1, 2, 4, 5 is not allowed and will be
reported as 3 modules; in this case, the modules addressed
4 and 5 must be corrected to 3 and 4, respectively.
How Product Groups Appear on the Control Panel
Module addresses set during installation determine the order in which Product Groups appear on the Control
Panel. If the rules for addressing described in the Installation Manual are followed, the rst (top) Product
Group should be Sources, with the next logical component Product Group in the signal path being the second
Product Group (e.g. ampliers, or maybe preamp EQs or processors). Here are examples of how Product
Groups might be congured on your Control Panel:
Electronics Speaker Product Group 903 Control
Product Group Product Group Number Panel Display
Sources - 0 1
Processors - 2 2
Receivers - 4 3
- Front Speakers 4 4
- Center Speakers 5 5
- Surround Speakers 6 6
- Subwoofers 7 7
Figure 5. Address Scan: In Control Panels, "E" refers to
Electronics switching modules and "S" refers to Speaker
switching modules.
Info Display PG Window

8
Notice that the Product Groups are in a logical order that represents the normal signal ow of the components if
they were “hard-wired.” Notice also that speaker Product Groups follow their related amplier’s Product Group. Your
particular demonstration needs may not require that all Product Groups be used, leaving some vacant (i.e. no attached
switching modules). If this is the case, then your 903 Control Panel can be used very creatively by programming a single
promotional system into each unused Product Group, for instant one-button activation.
The last Product Group can store up to 99 preprogrammed systems of your choice if there are no components assigned
to that Product Group. To enable this feature, DIP Switch “C” on the Control Panel’s Conguration DIP Switch array must
be ON. See the diagram on page 5.
Blank and printed labels for all types of component Product Groups are included with your 903 Control Panel. However,
you may wish to make your own labels using different words, symbols or languages. If so, custom label inserts can be
printed on 20 - 24# paper using the following specications:
Label size: .45” H x 2” W Max. Text Width: 1-3/8”
Text Center: 11/16” from left edge Max. Text Height: 3/8”
Selecting Products
To select a product from the Control Panel by the product number:
1. PRESS the desired Product Group Select Key if that group is not already Selected.
2. Enter a 1 or 2 digit product number using the numeric keypad (the Product Group display clears
and then ashes the new entry).
3. PRESS the Product Group Select Key to enter your new selection.
You may also simply wait 2 seconds and the new selection will be entered automatically without PRESSing
the SELECTED Product Group key. Any component in any Product Group can be SELECTED in this manner
(Auto-Enter).
To play multiple pairs of speakers in the same Product Group:
1. Make sure the desired speaker Product Group is SELECTED (LED ON).
2. Enter 1 or 2 digit number of speaker pair you wish to add and LPRESS Product Group key.
The SELECTED speaker’s Product Group window will alternately display the two speaker pair numbers. You may add
more speaker pairs in the same manner (depending on system limitations set during installation), but remember that you
could be presenting a severe load (low impedance) to the amp’s output, so be careful. Check the receiver or amplier
manufacturer’s recommendations for maximum number of speakers.
To deselect one of the speaker pairs playing in the same Product Group:
1. Enter the 1 or 2 digit number of the pair you wish to deselect, and
2. PRESS the corresponding Product Group key or simply wait for Auto-Enter.
Note: The maximum number of speakers that can play at the same time is determined by DIP Switch
settings on the 980 System Module Board. If you cannot select multiple speakers to play simultaneously,
please refer to the Installation Manual’s instructions on setting the 980 System Module or call the factory at
800-322-8346.
To turn off all products in a Product Group.
This may be done by either of two ways:
1) Deselect the Product Group by DOUBLE-CLICKing its Select Key, or
2) Deselect the ACTIVE product within that GROUP by entering its number again.
In both cases the result is the same. The Product Group window will display dashes (– –), indicating that the
Group is available, but not ACTIVE.

Storing and Demonstrating Component Systems
There are three different ways to store complete systems with 903 Control Panels. During product demonstrations,
it is normal to “build” a system for your customer as you qualify his/her needs during the selling process. Once the
components of the desired system are active, the system may be stored in one of the following ways:
1) LPRESS the A, B, or C keys. These keys are essentially used like scratchpad or “ash” memory.
Once a system has been stored in this way, PRESS A, B, or C to instantly compare the stored
systems. Future systems can be stored in A, B, or C by repeating the same process thereby overwriting
the previously stored systems.
2) LPRESS any unused Product Group Select Key to store the system that is currently playing. Once
stored, the system can be SELECTED by simply PRESSing the Product Group key. When selected,
“SY” will be displayed in the system’s Product Group window and all the components comprising
the system will have their numbers displayed in their respective Product Group windows. Future
systems can be stored in the same manner by simply overwriting with a newly selected system.
3) Store as 1 of up to 99 systems in the Systems Product Group. To do this:
• Select the Systems Product Group by PRESSing its Select Key.
(DIP Switch-C must be ON).
• Enter a 1 or 2 digit number (e.g. #22) for the system.
• LPRESS the Systems Product Group’s Select Key to store.
Continue this procedure to store up to 99 systems. Systems that have been temporarily stored using the A, B, or C keys
may be copied to the System Product Group to prevent being erased.
To select a system previously stored in the System Product Group:
1) SELECT the Systems Product Group,
2) Enter the 1 or 2 digit system number you wish to play, and
3) PRESS the Systems Product Group key or wait 2 seconds for auto-enter.

ABOUT SECURE FEATURES
Beyond the basic operational features are many special features and functions that can dramatically enhance the
switching system’s convenience and utility. Secure Features allow you to control and restrict access to the display, put
the switching system into the SLEEP mode, protect stored systems from accidental erasure, etc. These special features
are initiated with the SECURE Key. Properly used, Secure Features will eliminate most of the risks associated with giving
customers access to the switching system, making offensive “Please Don’t Touch” signs unnecessary. The Access System
is designed to be equally appropriate for operation by you or your customer.
Control over these special features is by two different SECURITY CODES – a MANAGER CODE and an OPERATOR
CODE. Whenever a Code is required to execute a Secure Feature, “coA” will appear in the display window to prompt
for the Manager Code, or “coB” to prompt or the Operator Code.
Security Codescan be any number from 0 to 999. Or, either Code
may be set to null or empty, to bypass the requirement of entering a
Code altogether. The Manager’s Code is used to control access to
certain system setup parameters, while the Operator Code is used
to restrict Customer access. The MANAGER CODE, or Code A, is
factory set at 999. The OPERATOR CODE, or Code B, is factory set
as blank or null.
Changing the Manger’s Code requires you to press and hold the
recessed button on the Control Panel. To reach the button, you must
unbend a paper clip and insert it through the hole in the Control
Panel (Figure 6). While holding the recessed button, short press
the A key. The Manager’s Code will appear. To change the code,
press the C key to backspace, and then enter a new three digit code
and long-press the A key to enter. Release the recessed button to
exit Change Password Mode. Changing the Operator’s Code is a
similar process: while holding the recessed button, short press the
B key. The Operator’s Code will appear. To change the code, press
the C key to backspace, and then enter a new three digit code.
Long-press the B key to enter. Release the recessed button to exit Change Password Mode.
All Secure Commands are initiated by PRESSing the SECURE Key, followed by the number of the desired feature or
function. During Secure Command key sequences, the SECURE Key is used like an “Enter” key to conrm input and
move to the next operator prompt. Also, the Arrow Keys, depicted as for UP and for DOWN, are used to toggle between
available choices. When one Secure Command has an impact on, or is dependent on another, that is also noted. The
Manager Code may be substituted at any prompt for the Operator Code. Of course, the opposite is not true.
Most secure functions have a TIMEOUT function that automatically terminates the command in process and puts you
back where you were previously if the keystrokes are not entered properly or if you take too long. So if you are interrupted
in the middle of entering a Secure Command, you need not worry about the system being inadvertently left vulnerable.
It may take a little practice for the Secure Features to become second nature. After all, this aspect of the Control Panel’s
operation is security related and should not be too obvious.
TIP: If you experience any initial uncertainty in entering any Secure Command, DOUBLE-CLICKing the SECURE Key will
terminate the current command sequence and return the Control Panel to its previous state, allowing you to start over.
The different Secure Commands are listed in the following section along with an explanation of what each code does.
Using the Secure Features
Please acquaint yourself with the Secure 91 and Secure 95 Codes rst, since they are generally required for other Secure
Features to operate. Generally, those Secure Features that are used frequently and by store personnel have lower
numbers to reduce keystrokes. Secure Features requiring the Manager Code to make changes generally have higher
numbers.
In this section, the keys to press are capitalized. Keystrokes are separated by a dot (•). The entry of numbers is indicated
by the # sign, one for each possible digit. An asterisk (*) indicates that a keystroke is optional, that is, it will automatically
execute if the key is not pressed.

USING PRODUCT SELECT BUTTONS
Product Select Buttons (PSBs) offer a very friendly interface
that encourages self-service. They also make a powerful
addition to the merchandising exibility of systems that use
Control Panels. If you have both a Control Panel and PSB,
notice that the PSBs communicate with the ControlPanel and
vice versa through the bidirectional architecture of your system.
Any selection made with a PSB will be conrmed by the PSB’s
LED and in the selected component’s Product Group window
on the Control Panel.
Usually, PSBs are located adjacent to the component they
select. To use a PSB, simply PRESS it momentarily. The green
LED will light and your selection will play, assuming you have
source material. PRESSing an alternate component’s PSB
will activate the new selection and deactivate the previous
selection. To turn a selected component OFF, simply PRESS
its PSB.
One can play multiple pairs of speakers using a PSB by adding additional pairs to the current selection (the maximum
number of pairs allowed is determined at installation). To add a pair of speakers to the current selection, LPRESS the
PSB for the set of speakers you wish to add. To deselect one of the multiple pairs playing, PRESS its PSB.
Product Select Buttons
A product select button is a momentary switch, usually with an LED to indicate when a product is selected. Each button
has a four-pin cable and four-conductor wire connecting the button to the switch module. Audio Authority carries several
button styles and colors, check with your Account Manager for colors and availability.
TROUBLESHOOTING
There are two common conditions that can cause a system to malfunction:
1) Switching Modules that are not properly addressed.
2) Buses are improperly connected (system bus, high-level bus, low-level bus).
Either of these conditions can cause the system to be “confused” since the Control Panel cannot then communicate
with all switching modules. All of the module addresses should have been set and all the bus networks connected
by the person(s) who originally installed your system. If this was not properly done or if any module addresses have
been changed, or new modules added to the system since the original installation, someone will have to verify all the
address settings and check all the bus connections in your system before further troubleshooting can continue. Run the

Denition of Terms
To successfully install your new Access Demonstration Network, you should familiarize yourself with the
following terms:
Active Any Component or Product Group that is currently selected to play, i.e. part of the
signal path. The 2-digit number for all active components is shown in its respective
Product Group window
Address A number that pinpoints the identity and location of a switch module within a system. The
installer sets numeric switches like the ones in Figure 20 for each module which provides
a unique address in the proper sequence for each component connected to the system.
Bus A Bus is a pathway for signals to travel from module to module; a cable connecting
modules. There are three types of buses found in most AccessEZ Systems:
• System Bus A four wire harness (red, black, yellow, blue) connected to every
Access module. The System Bus carries the signals that control the selection of
the components and perform various housekeeping functions among the modules
in the system.
• Speaker Bus (or High-level Bus) A four wire harness (green, white, brown, gray)
that carries speaker-level signals from source and/or amplier modules to
speaker modules.
• Low-level Bus A signal bus using RCA patch cables to carry low-level audio
signals between source modules and equalizer or amplier modules.
Control Panel Control Panels, like the 903, 906G or third party Touchscreen, add central control and
display capabilities to a system. Any control panel can operate hand-in-hand with product
select buttons.
Component The merchandise or products connected to the switching system.
Double-Click To press and release a key twice in rapid succession. Used for alternate key functions,
such as turning off an active Product Group.
Hold To HOLD a key down while PRESSing other keys, like the “Shift” key on a
computer keyboard.
Lpress To press and hold a key until the Control Panel beeps (about 1/2 second) then
release. LPRESS is generally used to store values. Examples are dening systems
and storing current selections using A/B/C keys, etc.

16
Module A basic component of the Access™ System. There are ve types of modules normally
found in home entertainment applications:
• Switching Modules select and connect products for demonstration and
communicate with other system components through the System Bus. Examples
are Models 922, 932, 942, 945 and 955.
• Expander Modules add channel capacity to switching modules. Examples are
Models 920X and 940X.
• System Module (Model 980) performs basic control, interface and housekeeping
functions within the system.
Press A momentary press and release of a key. The PRESS is used for primary key functions
like entering numbers or selecting a Product Group.
Product Group A group of functionally similar components within the display, such as DVD players,
or Group ampliers, subwoofers etc. The 903 Control Panel has provisions for eight product groups
and has capacity for 99 components in each product group.
Product Select A push-button mounted at, or near the product location. Pushing this button selects the
Button (PSB) product for demonstration and lights an LED to conrm the selection.
Selected The Product Group currently selected to be the object of keypad input. A Product Group
Product Group is selected by pressing its Select Key and conrmed by the illumination of its red LED
indicator. When selected, input from the numeric keypad will be displayed in the Product
Group’s 2-digit window and directed to its switch modules.
SilenTouch™SilenTouch mutes the sound for a brief period during the switching process to eliminate
transient noises while changing from one product to the next.
System 1. A network of switching modules interconnected by buses where a control panel and/
or PSBs are employed to select and thereby interconnect specic components for
demonstration.
2. A conguration of audio products or components playing together which can be stored
in control panel memory and A/B compared with other “systems.”
Timeout The automatic termination of an incomplete keypad or remote control command
after a set amount of time; the control panel is restored to its previous state.
