What is the Access™System?
The Access™ System consists of a variety of intelligent switching modules. These modules communicate with
each other via the “system bus,” allowing you to construct the exact demonstration system configuration you
desire from the sources, processors/equalizers, amplifiers, speakers, and subwoofers in your display. The
switching modules are located near the actual products on display creating a “distributed switching net-
work.” The products are connected to the modules rather than being wired to one central point. Selected
product signals are then sent across the network through “buses” that interconnect the modules. A simplified
view is shown below.
DEFINITION OF TERMS
To successfully install your new Access Demonstration Network, you should
familiarize yourself with the following terms:
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 for each module which
provides a unique address in the proper sequence for each
component connected to the system.
AutoDamping™When merchandising many pairs of different speakers in a
showroom, the drivers of the unselected speaker pairs
become passive radiators when the currently active
speaker pair is playing, absorbing much of the sound
coming from the speakers being played. AutoDamping™ is a circuit in the Model 93 that
electrically disconnects (shorts) speakers not being played, thereby automatically damping
them as passive radiators and improving sound quality in the showroom.
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
AccessEZ 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 Le el Bus) A four wire harness (green, white, brown, gray)
that carries speaker-level signals from source and/or amplifier modules to
speaker modules.
•Low-le el Bus A signal bus using RCA patch cables to carry low-level audio
signals between source modules and equalizer or amplifier modules.

Figure 2. This example shows an
address setting of 0/00. Typically
this would represent the first
module (components 1 through 4)
in the Source Product Group.

Bypass A way to hear a system without a particular in-line component (EQ, Crossover, Amplifier,
etc.). For example, when you wish to hear a system without the processor, the system can
route the signal past the processor group and directly to the amplifiers. In this expample,
Position #4 on the last module in the Processor Product Group is used as the bypass
location. When this position is selected, or the Product Group is deselected, the audio
signal continues through the bypassed group to the next Product Group. To activate
bypass, turn ON the Bypass switch only on the last module in the group.
Control Panel Control Panels, like the 90 , 903, 906 or AccessPC Touchscreen, add central control and
display capabilities to a system. Any control panel can operate hand-in-hand with prod-
uct select buttons.
Module A basic component of the AccessEZ™ System. There are five types of modules normally
found in car audio applications:
•Switching Modules select and connect products for demonstration and commu-
nicate with other system components through the System Bus. Examples are
Models 910D, 9 , 93 , 94 and 958.
•Expander Modules add channel capacity to switching modules. Examples are
Models 9 0X and 940X.
•System Modules perform basic control, interface and housekeeping functions
within the system. Examples include Models 980 and 988.
•DC Power Modules distribute DC power to sources, EQs, and amps. Examples
include Models 915X and 916X.
•Signal Distribution Modules, such as the 985EZ and 975, distribute audio and/or
video signals to output devices such as Video monitors.
Position The numbered point of connection (1-4 for electronics, or 1-8 for speakers) of a product to
a switching or expander module. The product select button (PSB) must be connected to
the corresponding position on the module. For example, if a component is connected to
position 3, its product select button must be connected to PSB position 3. When a “bypass”
is required, always use the fourth position (see “bypass”). Control Panels select positions
through the System Bus, and are not connected to individual positions.
Product Group A group of functionally similar products, such as sources, amplifiers, subwoofers, etc.
product group also refers to the windows to the right on 90 /903 control panels.
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 confirm the selection.
System 1. A network of switching modules interconnected by buses where a control panel and/or
PSBs are employed to select and thereby interconnect specific components for demonstra-
tion. . A configuration of audio products or components playing together which can be
stored in control panel memory and A/B compared with other “systems.”
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.
TheftAlert™A special circuit that senses ground continuity of the products connected to the switching
modules. If an alarm device is connected to the system, it will sound if a product is
disconnected from the system without authorization. TheftAlert is an optional feature
available through your Audio Authority® Account Manager. TheftAlert may also be added
after your initial purchase. A special transformer is required for the feature to work and is
provided per your request. You then will need to install it in the proper position on the
switch modules.

HOW THE ACCESS™SYSTEM WORKS
When a product is selected for demonstration, signals are sent through a network of buses between switching
modules to activate that particular product position.
Selecting Products in the Access System
Products can be selected in a system in different ways that can all be combined into a single system, if desired.
You may select products in the following ways:
• By pressing a Product Select Button (PSB) connected to a switching module. This allows the user to build
different systems of product configurations manually.
• By using a control panel, if the system is so equipped. Control panel use is covered in detail in a separate
manual that accompanies each control panel.
• By issuing commands with the Model 905 IR Remote Control, which is included with the 90 Control
Panel and available with the 903. One 905 remote is recommended per salesperson.
• By using a computer touchscreen with AccessPC or custom software configured to enable product selec-
tions and other control functions.
• A combination of these methods.
Buses
Signals are passed between modules by “buses,” which are nothing more than cables that go from module to
module to module, connecting them into functional groups within the system’s architecture.
The System Bus connects all switching and system modules, allowing them to send messages to each other,
controlled by the addresses that are set by the installer. These signals instruct the modules to select the
inputs/outputs of a particular unit, such as a head unit or amplifier. Expander modules are not connected
directly to the System Bus. Each expander receives its instruction from the main switch module to which it is
attached.
Signal Buses carry audio signals, either low-level (source low-level output, for example) or high-level signals
(amplifier output).

902 Features include:
• Displays selected products, even when they are selected using Product Select Buttons or by remote
control. Displays diagnostic information for troubleshooting the system.
• Removable Product Group insert labels can be changed to indicate the functions of the LED
displays. An extensive set of labels is included with the control panel.
• Amplifiers can be connected to more than one Product Group allowing one amplifier to be demon-
strated independently as a front, rear, or sub amp (amp sharing).
• If not assigned as an active Product Group, the control panel’s last Product Group can store up to
99 pre-configured systems for immediate recall.
• Speakers with varying input sensitivities can be equalized to play at matched volumes by attenu-
ating the output level of the source. AutoCal™ program can run automatically or calibration
values can be directly written into the system’s memory.
• Optional TheftAlert™ circuit can be armed to sound an alarm should products on display be
disconnected without authorization.
