Introduction

The AccessEZ™ series of demonstration system modules provides a plug-in solution for home, portable audio and car
audio switching systems in retail display environments. This second generation of the highly capable, industry-acclaimed

Access™ System modules offers many new features and benets:

• AccessEZ offers a compact module to t each kind of product, compared with a patchwork of printed circuit boards.

• Modules are protected by attractive and rugged steel covers.

• Expansion, when needed, is done by directly “docking” Expander modules.

• Comprehensive control panels with automated demonstration features.

• Single product group control panel for soundbars, in-wall speaker displays, or any product category.

• Your choice of button-per-product, central control panel/third party touchscreen, or any combination of user interface.

• Sophisticated SilenTouch™ interval muting for quiet switching.

• Capacity for hundreds of products.

All of these features make it easy to design the demonstration system that ts your specic merchandising needs. Your
Account Manager and our Application Engineering staff can assist you in selecting and conguring the appropriate
AccessEZ™ modules to build the ideal system for you.

What is the Access™ System?

The Access™ System is a network of intelligent modules including product selectors, control modules, and signal expander

modules. These modules communicate with each other via the “system bus”, allowing you to construct and control the
exact demonstration system conguration you desire from the sources, receiver/ampliers, speakers, subwoofers and
video monitors in your display. The modular architecture allows the switching modules to be located near the actual
products on display creating a “distributed switching network.” The products are connected to the modules rather than
being wired to one central point, simplifying installation. Selected product signals are then sent across the network through

“buses” that interconnect the modules.

Buses

Signals are passed between modules through “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 source or receiver. 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), high-level signals (amplier
output), or video signals.

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 or a combination of these methods:

Figure 3. Figure 4. Figure 5.

By pressing a Product Select Button

(PSB) connected to a switching
module. PSBs may be used in the
same system with any control panel or
as the sole method of control.

*A touchscreen interface requires custom software that may be created by the user or by Audio Authority.
Custom software charges apply.

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 using a computer touchscreen
with custom software* congured to

enable product selections and other
control functions.

Access™ System Components

User Interfaces

903 Control Panel

• Displays selected products, even
when selected using Product

Select Buttons or other methods.
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.

• If not assigned as an active product
group, the control panel’s last
product group can store up to 99
pre-congured systems for

immediate recall.

• The control panel or any specic
product group can be “locked out”

from unauthorized user input.

906G Control Panel

Perfect for DVD displays, speaker walls, or
home theater package systems. The 906G

Control Panel selects products from one

Product Group, using a rotary encoder knob, and displays the selected product
number in the LCD window. Use the Select Previous button to make instantaneous

comparisons between products. Two 906G Control Panels may be used in one
system, one 906G for each Product Group.

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-conductor (or two-conductor)
cable connecting the button to the switch module (See page 25 if using
two-conductor buttons.) Audio Authority carries several button styles and colors,
check with your Account Manager for colors and availability.

Touchscreen Graphical User Interface

The Access system allows any device to send and
receive commands via RS-232. This includes
a computer with a touchscreen GUI. You can
develop your own interface and connect the
device to our Model 970A Serial Interface

Module via serial cable. Developing a GUI may

be impractical for one or two displays, but it can

be an excellent solution for retailers that have

dozens of locations.

Model 955 Source Selector Module

Model 955 controls four audio/video sources, including digital audio (coax) as well as composite
video. Bus connections are directional (IN from previous source module/OUT to next source module or to next
product group.)

7

Receiver, Amplier and Soundbar Modules

Model 942 Amplier Selector Module

Model 942 controls four two-channel ampliers or receivers. One module accommodates both low-level inputs
and high-level outputs. For high current amplier applications, use 922 for input, but dock a heavy duty 949X
module to it to switch the high current speaker output signals (See also 939 below.)

Model 945 Receiver Selector Module

Model 945 controls four Surround Sound or Digital Audio receivers. One module accommodates low-level and
Digital Audio inputs and front/center/surround high-level outputs, as well as low-level Subwoofer output. Bus
connections are directional (IN from previous receiver module or previous product group/OUT to next
receiver module).

Model 956 Soundbar Selector Module

Model 956 controls four soundbars, digital-to-analog converters, or receivers (with dedicated speakers). One
module accommodates digital (Toslink®) and stereo analog inputs allowing PCM, Bitstream, Dolby TrueHD and

DTS TruSurround.

Speaker Modules

Model 932 Speaker Selector Module

Model 932 controls one channel (e.g. left or right) of eight speakers. Two 932 modules are required for eight
stereo pairs. Use one 932 for center speakers or speaker level subwoofers.

Model 939 High Current Speaker Selector Module

For high current applications, use 939 in place of 932 switch modules (See also 949X on page 7.)

Model 940 High-Level Selector Module

Model 940 controls four speaker pairs, but does not offer SilenTouch™ or AutoDamping™. Use Model 932 for

applications where SilenTouch™ and AutoDamping™ are desired.

SINGLE PRODUCT GROUP SWITCHING SYSTEMS

Individual Access Modules

Most products can be switched with a single AccessEZ™ module, and generally, a 980 System Module. Product Select
Buttons (PSBs) may be installed next to each product or a 906G Single Product Group Control Panel can be used. If
the system is expanded to switch multiple sources, receivers and speakers, the Access™ system can be modied by
adding the necessary switching modules. This section provides a general overview of system layouts; for detailed hookup
instructions, see Appendix A.

Device

Use a 922 Low-Level module for every four CD players, music servers, or satellite radio receivers you plan to

include in your switching system (Figure 10). Connect each source to a 922, and connect the system bus and
low-level bus from the 922 module to the “Bus In” jacks on the 980 System module. Connect an RCA patch cord
from the low-level “Bus Out” jacks on the 980 to the CD input of a dedicated receiver and add a pair of speakers
to complete the display. To add more sources, add 922 modules. For example, to add sixteen sources, connect
system bus and low-level bus from the rst 922 to four more 922 modules.

TV Soundbars

Use a 956B module (Figure 11) for every four soundbars to be demonstrated. The HDMI video from the source
connects to the TV. The 956B switches any digital audio format including Dolby®. To add soundbars to your
display, add 956B modules. For example, to add eight soundbars, add two 956B modules. Connect all modules
with system bus, and all 956B modules with audio/video bus. Be sure to follow signal ow when connecting bus
jacks labeled IN/OUT.

Figure 11. Four Soundbars with dedicated TV. Insert an EDID control device in the HDMI pathway to choose an audio soundstage;
otherwise the TV may cause the source to output 2-channel PCM.

Surround Receivers

Use one 945 module for the input/output for every four receivers (Figure 12). The analog audio bus connects the
dedicated source to the 980 module, and from there it links all the 945 modules in the receiver group. Be sure
you properly connect the bus according to signal ow. The digital audio bus comes directly from the dedicated
source to the 945 module’s IN jacks. Connect all main modules with system bus and speaker bus (for more
detail, nd “bus cable installation” in the index.) To add receivers, just add switching modules. For example, to

add 12 receivers to a surround switching system, add three 945 modules.

Stereo Receivers

Use one 942 module for the input/output for every four stereo receivers (not shown). The low-level bus connects
the dedicated source to the 980 module, and from there it links all the 942 modules in the receiver group.
Connect all main modules with system bus and speaker bus (for more detail, nd “bus cable installation” in
the index.) To add receivers, just add switching modules. For example, to add sixteen receivers to a 2-channel
switching system, add four 942 modules.

Stereo Speakers

The 932 Speaker Module lets you place switching modules close to the merchandise, dramatically reducing
wiring runs. Each 932 handles up to eight speakers in one channel (Figure 13). For every eight speaker pairs,
use two 932 modules, one for the left speakers and one for the right. Install the 980 module between the source

and the receiver in the low-level bus as shown. Connect the 980 and all 932 modules with system bus. To add

speakers, add 932 modules. For example, to add sixteen speaker pairs, add two left 932s and two right 932s. To
demonstrate four speaker pairs (or fewer), use a 940 module (not shown) and a 980 module.

MULTI-COMPONENT 2-CHANNEL SWITCHING SYSTEM

Designing Your Own Application

Home audio demonstration systems can be designed in different
ways. This section explains the basic switching congurations
for a 2-channel display including several sources, receivers, and
stereo speakers. The architecture of Access™ makes it possible
to design a system that ts your needs exactly. Your Account
Manager can help you choose the modules and user interfaces
that will best suit your needs and product mix. If you wish to
change your merchandising approach in the future, Access™

can be rewired and additional modules can be installed to

accommodate a different conguration.

Stereo Receivers Stereo Speaker Pairs Stereo Sources

Organize Products into Groups

When planning the installation, think of each component
type you wish to display as belonging to a particular
family or group, and where each component might
reside in the signal path for a typical audio system.
Generally the Product Groups fall into these categories:
Sources, Receivers, and Stereo Speakers. Only one

product can be selected from each Source and Receiver
Product Group at a time. The Access system can allow up to

four pairs of speakers to play at once in parallel, but you can
determine that number by setting the Speaker Limit Switch

on the 980 System Module.

Note: Some receivers are not recommended to play
more than one speaker pair.

and their order in the signal path (left to right.)

List the Switching Modules

Figure 15 shows the modules needed to switch each type of product in this example display. Each electronics
module supports four products, and each speaker module supports eight speakers. To switch eight speaker
pairs, use one 932 module for the right, and one for the left. The Access System’s architecture was designed for
up to sixteen unique speaker groups, with a capacity within each group for 99 pairs of speakers.

HOME THEATER SWITCHING SYSTEM

Designing Your Own Application

This section explains the basic switching congurations for a 5.1 channel display including several digital sources, Dolby
Digital 5.1, 7.1 or Atmos receivers, surround speakers and subwoofers. Your Account Manager can help you choose the
modules and user interfaces that will best suit your needs and product mix.

Organize the Products

When planning the installation, think of each component type you wish to display as belonging to a particular
family or “group,” and where those components might reside in the signal path, for a typical home theater
system. Generally home theater Product Groups fall into these categories: A-V sources, digital receivers, center,
front and surround speakers, and subwoofers. Only one product can be selected from each electronics Product

Group at a time.

List the Switching Modules

Figure 18 shows an assortment of home theater products you may wish to demonstrate. Figure 19 shows the

modules needed to switch each type of product in this example system. The Source Group may include DVDs,
Blu-ray Players and streaming media devices. Each electronics module supports four products, and each
speaker module supports eight individual speakers. To switch eight speaker pairs, you need two 932 modules:
one for the right and one for the left. For small systems, you can use one 940 module to switch four stereo pairs.
932 modules are better for ve or more speaker pairs because they will automatically prevent unselected pairs
from vibrating sympathetically with the selected pair (AutoDamping™).

Put the System Together

The only other essential module is the “System Module.” It controls certain functions of the Access System, such as
SilenTouch™ (a muting interval) and provides a place to connect a control panel and power supply. A 980 System Module

is shown installed in the signal path between the Source Group and the Receiver Group. By connecting the modules with
bus cables (explained in the denition of terms section) you now have a working switching system.

Add More Products

Simply add enough modules to accommodate the number of additional products you plan to demonstrate.
Instead of four A-V Sources, the example in Figure 21 can demonstrate eight Sources. If you plan to use a 903
Control Panel or PSBs, you can demonstrate up to 99 products in each of eight Product Groups.

Subwoofer Switching Options

Powered subs can be wired low-level in systems where all receivers have a low-level “Sub Out” jack, or they
can be wired high-level, tapping into the full range signal for the front speakers. Call Audio Authority® for more
information on wiring high-level subwoofers. Low-level mono or stereo subwoofers can be switched using the
922 module. For mono subwoofers, use only one channel or use a Y-adapter cable (shown below) to provide
signal to both channels, reducing hookup errors.

VIDEO DISTRIBUTION SYSTEMS

Working with HDMI Signals

Video switching and distribution congurations are both used in retail stores. For a simple video demonstration where one
source device feeds HD video to multiple displays, our HDMI distribution amplier is ideal. You can also use it as part of
the solution when demonstrating HDMI via multiple AVRs. If the capability for video on-screen programming is desired, the
video bus from the source group must be looped through the Receiver Group, and then connected to the video distribution
system. That conguration requires an HDMI switcher as well. Choose a switcher with RS-232 so that it can be controlled
using our Model 970A with custom programming. See an example system here:
www.audioauthority.com/page/hdmi_audio_demo or call for consultation about your specic needs.

ADDING CONTROL INTERFACES

One Interface or a Combination of Interfaces

Your system may be operated by PSBs alone, or you can use a control panel, or both. Your Audio Authority® Account

Manager can help you choose the user interface combination that best suits your needs. Call 800-322-8346.

903 Control Panel

This full featured control panel offers all the selling tools necessary for an effective presentation by qualied sales staff. To
add a 903 to your system, simply plug the Control Panel cable into your 980 System Module as shown.

906G Control Panel

This single product group control panel plugs into the system bus port on any AccessEZ switch module. Set the address
switches to match the address of the target product group’s switch modules. Multiple 906G control panels may be used in
one system, e.g. one 906G controlling sources, another 906G controlling receivers, and a third 906G controlling
speaker pairs.

Custom Touchscreen Software

To use a third-party touchscreen for Access system control, custom software must be congured to work in conjunction
with the 970A. The 970A is connected to the Access bus where it can receive switching commands from any RS-232
device. It also transmits replies and system queries back to the control device.

INSTALLATION

1. Preparation

Follow these steps carefully:

• Review the design of the demonstration area, and make sure the display shelving is correct for your installation.

• Look at the supplied system wiring diagram, or choose one from this manual to serve as an example. Examples are in
Appendix A: Sample Systems.

• Gather the owner’s manuals of other products that are part of your system for reference during the installation.

• Gather the tools and materials you will need. The list below will cover most installations.

• #2 Phillips screwdriver bits

• 1/8” straight (at head) screwdriver

• Power screwdriver (especially one with a torque clutch)

• Wire cutter/stripper

• Cable ties (4 inch are ne)

• 7/64 inch and 3/4 inch drill bits

• 7/16 inch nut driver or open-end wrench

• Flashlight

• 14-18 gauge speaker wire

• High quality RCA patch cords. Any RCA patch cords are suitable for the low-level bus or component
connections; however, we highly recommend that you use low-capacitance RCA patch cables for
optimum system performance and reliability, especially when demostrating turntables, or when longer cable

runs are necessary.

• Check the contents of the shipping cartons. If your system is not pre-installed in a xture or on workboards, use the
packing list and your wiring diagram to determine how each component ts into your wiring plan. Refer to the “Access

System Components” section to help identify the various items.

2. Addressing

A. Number the Product Groups.

Each main switching module has a set of switches for assigning the unique ID or address of that module.
First, determine the portion of the address called the Product Group number. Refer to your system plan to

make a chart like the one below. Start with a Source Group if there is one; otherwise, start with the rst Product Group in
the audio signal path to be switched (TV monitors are not “switched” so they are not assigned a Product Group number.)

Electronics Speaker Product Group 903 Control

Product Group Product Group Number Panel Display

Sources - 0 1
Processors, Preamps - 2 2

Receivers, Ampliers - 4 3

- Front Speakers 4 4

- Center Speakers 5 5

- Surround Speakers 6 6

- Subwoofers 7 7

TECH TIPS

Each group must have a higher number than the previous group in the signal path. Some numbers may be skipped if

appropriate. Note that the receivers and front speakers always have matching group numbers. This determines how the
903 Control Panel, if used, handles display layout of the products in these Product Groups. Figure 25 shows how the 903

Control Panel would arrange these Product Groups on its Product Group display windows.

Be sure to set the receivers to the same Product Group number as the front speakers.

15

Speaker Groups

The Access™ System allows a

maximum of 16 unique speaker
groups, with a capacity within each
group for 99 pairs of speakers.
Some of the unique speaker group

possibilities are:

• Front Speakers

• Center Speakers

• Rear Speakers

• Surround Speakers

• Side Speakers

• Center Rear Speakers

• Ceiling (Atmos) Speakers

• High-Level Subwoofers

• Low-Level Subwoofers

Figure 25. This is how Product Groups appear on the 903 Control Panel. The

display shows which product in each group is selected.

B. Determine the Module ID settings.

Number the modules in each Product Group to organize the products to the desired order within the Group.
Each unique Group can contain up to 99 products.

See the chart below for the correct Module ID setting for each module.

C. Set the Address Switches.

Remember, begin with Group 0/ 00 for the rst module in the Source Group,
and the next module is 0/01. If the Receiver Product Group is next, the rst 945
module will have an address setting of 4/00 (Figure 26), so the rst module in the
Front Speaker Product Group would be 4/00 as well (Figure 27). For an example
system showing addressing, see Appendix A.

D. Set the Programming Switches.

Determine the settings for any remaining switches on each module.

S M B T D (Single Ch., Multi Ch., Bypass, Time, Delay)

The 942 Amplier Module has an array of ve switches used mostly for
Car Audio Demonstration. All of these switches should be OFF in a home

audio demonstration system unless Bypass is required.

Bypass

The Bypass switch should be set to OFF unless you wish to bypass

the Source Group. A recordable DVD player is an example of a Source
Group that might be bypassed. The Product Group will be bypassed
when all the products in that group are unselected. The “bypass

module” is always the last module in the Product Group (only the
bypass module should have the Bypass

switch ON.) For more on bypass, see the
index.

Figure 26. Model 945 Receiver

Left – Right

The 932 Speaker Module (shown right)
has a Left – Right switch in the lower
left-hand corner. For Left speakers,
switch it to the “left,” for Right, to the
“right.” For speakers such as mono

centers or mono subwoofers, the switch

should be set to the “right” position.

E. Fill Out the Labels.

Check all switch settings against your addressing
plan or system drawing. Each module has blank
boxes printed on the metal case. After you have
established your switch settings, use this space
to record the correct settings. Fill in the outlined

arrows with the actual product numbers to be
switched by this module as shown in Figure 27.
This process will help with maintenance and

troubleshooting later.

3. Install the System Hardware

A. Designate the Switching Module Locations

Determine the location for each switching module. Each module controls either four or eight products.

• Follow your system plan design to determine the location of the switching modules in the display xture. If
you are using bus cables provided by Audio Authority®, you may wish to connect all the modules that share
the system bus with system bus cable, power up the system on a bench or table, and check the switching
modules and control panel logic before actually installing the modules in your xture.

• Mark the location of the switch modules near the center of the products they will serve. Modules will serve
four electronic components, or eight speakers.

• Be sure to consider the two foot plug spacing if you are using pre-made factory bus cables.

B. Determine Other Module Locations

In the following installation steps, ignore any references to modules that are not part of your system.

• Position the 980 System Module in the signal path immediately prior to the rst module(s) in your Receiver
Product Group. This position will allow you to feed analog audio signals from the output of your Source
Product Group to the System Module which will then feed the low-level input signal to your Receiver Product
Group. Do not route video or digital audio signals through the 980 module.

C. Mount the Modules

• Use the screws provided with each module.

• Connect any audio signal expander (“X” module) to its respective
main switching module by plugging it directly into the bottom of the
main module as shown. If you encounter difculty with this procedure,
call the factory. It is critical that any signal expander modules be

connected to a header port on the main module labeled “Expand”
or “Expansion.”

Do not plug an audio signal expander module to the header port labeled “DC
Expansion” on the top of 922, 940 or 942 modules (See Figure 28.)

4. Install the Bus Cables

Figure 28.

Pre-assembled bus cables or the raw materials to make the necessary bus cables
on the job site were included with your system purchase. Pre-assembled bus cables have connectors every two feet (RCA

patch cords are available in lengths from three to twenty feet.) If you plan to make your bus cables on the job site, you’ll

need connectors and the special bus assembly tool.

If you are making your own bus cables, be very careful to follow the assembly instructions, especially concerning wire
to connector polarity. Incorrect bus fabrication can cause system failure and damage! Several types of bus cables are
available for specic purposes:

Module expander red/grey/purple/blue/green 802-177

* The System and Speaker Bus extension cables allow you to join remote sections of the Access™ System with the main electronic component

section of your display, as in the case of surround speaker modules in a home theater display xture.

A. Install the System Bus

BUS

The System Bus allows all of the Access™ components to communicate among
themselves, and with the control panel. You may use either header in the location
labeled System Bus. Do not connect System Bus to any expander modules such as the
920X, or 940X. Be careful to observe the correct polarity as shown in Figure 29 (header
connectors are keyed for polarity).

1. Either use pre-assembled bus cables, or assemble bus with cable and 4-pin plugs
(part number 916-0470) using the special assembly tool. If you are making your
own system bus, be sure to leave a small amount of slack in the wire between

the modules and be very careful to assemble the connectors with the wires in the
correct order.

2. Starting at one end of your system, mate one plug of the system bus cable with
either of the 4-pin headers in the location marked System Bus on each module as
shown in Figure 30. If one cable is not long enough, or if you want to make a branch
from your cable run, you may begin another run by plugging it into the vacant

System Bus header. Otherwise, that header may be left vacant.

3. If you are using pre-assembled buses, you may use a system bus extension cable
for long distances between modules. (Or carefully splice 22 gauge cable
where needed, call Tech Services for assistance)

B. Install the Speaker Bus

The Speaker Bus will be used to send high-level signals from receiver outputs to other
high-level modules in the system. It is a green/white/brown/gray cable.

BUS

• Be careful to maintain correct polarity as shown in Figure 31.

• Install the Speaker Bus in the same way you installed the System Bus. For stereo
switching systems, plug a 4-pin Speaker Bus connector into a header marked
Speaker Bus on every 942 module.

• For surround sound switching systems, make three individual buses: Front, Center,
and Rear Speaker Bus. Begin at one end of your Receiver Product Group, and
plug the rst Speaker Bus into a header marked Front Speaker Bus on each 945
module. Plug the next Speaker Bus into a Center Speaker Bus connector on each
945, and the last bus into the Surround Speaker Bus headers in the same way.

• Now connect the Speaker Bus (or Buses) from the Receiver Product Group to
the Speaker Product Group (or Groups for surround sound systems). Plug one
end of the Front Speaker Bus into a 942 or 945 module, then plug a Speaker Bus
connector into a header marked Speaker Bus on every 932 module in the Front
Speaker Product Group. If it is more convenient, connect one channel (e.g. Left)

with one run of bus cable, and the other side with a separate run of cable. Continue
in the same way with the Center and the Surround Speaker Product Groups.

C. Install the Low-Level Buses

Low-Level

• The Low-Level buses carry signals from the Source Product Group to the Receiver Product Group via RCA patch
cables. Be sure to observe IN/OUT bus wiring on 955 and 945 modules.

• The Left and Right Audio Bus begins in the Source Product Group, and continues through the Bus In and Bus Out
jacks of the 980EZ and then on through the Receiver Product Group.

• The Digital Audio Buses follow the same route, but DO NOT loop through the 980 module. Connect them directly from
the Digital Audio Bus Out jacks on the 955 modules to Digital Audio Bus In jacks on the 945 modules.

• Composite Video Bus connects to the yellow Composite Video jacks on the 955 modules, and on to the TV monitor
(See Figure 33.) For HDMI switching, see audioauthority.com/hdmi-demo for details.

• The Subwoofer Output Bus is connected from one 945 to the next, and nally ends up at the Subwoofer

Product Group.

Before continuing any further, double check the following:

• Check the Group and Module ID settings on all modules. Your Group numbers
should follow a similar pattern to the example in Figure 34. Make sure the
Module ID settings are in consecutive order in each Product Group, beginning
with zero, not skipping any numbers.

• Check any Expander Modules in the system to insure that audio signal
expanders are connected to the Expansion header on their main modules, and
not a DC Expansion header. When docking 920X Expansion modules to speaker
modules, ensure the 4-pin connector matches the correct positions (1-4 or 5-8).

• Check programming switches, especially the Left -Right switch. 932 modules
on the left side of your display should be switched to Left, and on the right side,
Right. For mono center channel speakers or mono high-level subwoofers, set the
switch to Right.

• Check signal bus routing. Follow the physical path of signal buses from source
group products, through intermediate product groups, and out to the speakers
and TV monitor(s). Check Bus In/Out wiring on 955 and 945 modules.

• Check the System Bus and Speaker Buses for correct polarity, and make sure
the keyed plug is engaged with all four pins on each header and in the correct

direction as shown in Figure 36.

INSTALLING A CONTROL METHOD

1. Installing a Control Panel

Skip this step if you do not have a 903 or 906G Control Panel. If you have a 903 Control Panel, it is accompanied by a
separate User’s Guide which you should locate for future reference.

Note: The 903 Control Panel can also be remotely controlled using a third party IR remote programmed with the IR codes
available at audioauthority.com/access_tips.

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.

• For a 906G Control Panel, cut an opening 4 -1⁄16” (105 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 5 of your 903 User’s Guide for
more information on Product Group labeling.

B. Using the ten foot cable supplied, plug the 903 into the 980 System Module at the header marked 903.

C. Set the Conguration Switches on the control panel (See Switch Settings on page 24.)

D. Mount the control panel using the four screws provided. Do not overtighten the screws.

2. Installing Product Select Buttons

You may use product select buttons (PSBs) alone, or in conjunction

with a control panel.

A. Determine where each PSB will be located, usually close to the

product the PSB will select, and often near product

information tags.

• For plastic Model 999 PSBs: drill a 11⁄8” hole in the

panel or surface. Remove the nut and feed the switch

through the hole. Tighten the nut and install the white

switch mechanism.

• For stainless steel 803-190 or PSB-224: Drill a 3⁄4"
(19 mm) hole. Maximum panel thickness is 1⁄2”
(12.5 mm). Required depth is 2” behind front panel
surface. Tighten the nut.

B. You may wish to leave the PSB mounted in the product panel,

or install them later, after your components have been mounted.

module has either 2-pin or 4-pin headers above the product connectors
numbered from 1-4, or 1-8 (Figure 39). As you install the display products, you

will connect the PSBs to these headers using the cable assembly supplied with
each, being careful to observe proper polarity (Figure 40).

Note: When using
2-wire buttons

3. Installing Remote Switches (980 System Module)

In systems without a control panel, it is often desirable to add
“outboard” switches for remote operation of certain system

management tools.

A. Remote Power Switch.

• If your system does not include a Control Panel,
you may want to turn the system on and off using
a remote key switch or toggle switch.

• Use any SPST (single-pole, single-throw) switch
you prefer. Low current switches will work

perfectly well.

System Reset

Power

• Connect the switch between the “Power” and
“Com” pins of the 980’s ”Remotes” terminal block.

B. Remote System Reset.

• There is a “System Reset” button on the 980

that enables the user to reset the system in

the unlikely event that the system “hangs up.”
Pressing this button will re-boot the entire system.
Having a Remote Reset switch is a good idea in

any system since the 980 is usually buried inside
the display and would not be readily accessible
if the system ever needed to be reset. You may
wish to “hide” this remote switch from
customer access.

• Connect a SPST switch (Figure 42) between the “Reset” and “COM” pins on the “Remotes” terminal
block located on the 980 (See Figure 41.)

• Your system can now be “Reset” using this remote switch.

TESTING SYSTEM FUNCTION

1. Normal Operation

After installation is complete, all the system’s components need to be tested.
Apply power to the system and observe the following signs of normal operation:

• The green SilenTouch™ LED is lit on

the 980.

• The green Power LEDs on the switching
modules and the 980 are slowly blinking.

• The red 980 Low Voltage LED is not lit,

or is very dim.

Note: If the Low Voltage LED is brightly lit, your
system will not function. Check the output
voltage of your power supply and contact Audio
Authority Technical Support.

• For the moment, ignore the color of

the clear LED “Bus Monitor“ on the

980. Later, when product selections
are made, you will notice that the Bus

Monitor LED ickers and is an orange
color. This orange icker is normal. It
merely indicates that “trafc” is present on the bus.

2. 903 Test Sequence

Test the Control Panel (if your system does not have a 903 Control Panel,

skip to step “3” and ignore other references to control panels.) 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-blue­black 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.

Figure 44.

Info Display Product Group

Window

d. Call Audio Authority® Technical Service at 800-322-8346 for assistance with parts replacement.

26

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, 945, 955, 956, (all electronics), 932, 939, (speakers).

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 (See page 17.)

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 Product Group

window (Product Group, Figure 45), 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 that has

four “E Group 0” modules, four “E Group 4” modules, and
three pairs of “S Group 4” modules:

1. The top Product Group window displays “E0” as Info

Display scans up to 4 (good).

2. The second Product Group window displays “E4” as

Info Display scans up to 5 (bad)

3. The third Product Group window (shown in Figure

Figure 45. Address Scan: In Control Panels, "E" refers to

Electronics switching modules and "S" refers to Speaker
switching modules.

Info Display Product Group

Window

45) 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.

DEMO PRODUCT INSTALLATION

It is now time to begin installing the audio-video components. If you’ve followed the instructions so far, you will have a
working system in short order. It may be a good idea to map out a wiring plan for the audio and video components before
you begin connecting them to the switching system and to AC power. Make sure you will have access to the switching
modules from either the front or rear of your xture shelving.

Usually, it works out best to mount the components to be located at the bottom of your display rst, and work towards
the top of the display so you can avoid masses of hookup wire hanging down from above. Remember that the position of

each component on the shelf should match the number you wish the control panel to display. For instance, in Figure 50

the component in the display is on the bottom shelf, so it should be connected to the set of jacks on the switching module

for component number 4. The Control Panel will now display “04” when this component is selected.

Be sure to save the boxes and accessories for the components so that you can offer your customer a new or almost new
unit when you later take the component out of the display.

1. Install the First Products.

Install one product in each group in order to get a simple system
running. For example, install a source, a receiver, a pair of front
speakers and a TV monitor. Leave your power source on but be
careful using metal tools. If your system does not include PSBs,
ignore any references to PSBs.

A. Sources

Connect a source to an AC power outlet and its low-level audio
or A-V outputs to a product position on the source module (See

Appendix B for hookup diagram.)

• Connect the source unit to the product position on a

922 or a 955 Switch Module.

• Connect the low-level output to the source module’s
red (R) and white (L) female RCA jacks, and

connect composite video output to the yellow RCA

jacks if demonstrated.

• Connect Digital Audio outputs to a 955 module. If
coaxial outputs are not available, use a converter

such as a Model 977T.

• Connect the plug of the PSB’s cable (if PSBs
are used and are not already hooked up) to
the PSB port next to the arrow with the number
corresponding to the source you are connecting.

See Figure 40.

• Install the device in your shelving or cabinet.

B. Receivers

Connect a receiver to AC power. Then connect the receiver’s
audio inputs and speaker outputs to the 945 or 942 Receiver
Selector (See Appendix B for hookup diagram.)

• Connect the receiver to the Audio jacks using high quality RCA and/or optical cables.

• Use 14 or 16 gauge speaker wire to connect the unit’s speaker outputs to the corresponding terminal plug
(front, center, surround). If you are switching subwoofers with low-level, use RCA patch cords to connect the

Subwoofer output from the receiver to the 945.

• If you plan to use video on-screen programming, connect HDMI ports on the receiver to the appropriate

switches and distribution amps as shown here: audioauthority.com/hdmi-audio.

• Install the unit in your shelving or cabinet.

29

C. Speakers

Install a pair of speakers in the Front Speaker Group.

• Connect the left speaker to one of the two position terminal blocks on the Left 932 and the right speaker
to the corresponding position on the Right 932. Wire the positive lead to (+) and the negative speaker
lead to (–).

• Connect the plug of the PSB’s cable, if PSBs are used, to the 4-pin headers on the 932 circuit board at the
corresponding product position. Press the PSB into the hole you drilled earlier in the mounting panel or
display xture.

Note: One PSB will activate both left and right speakers when selected. You may wish to install a PSB on both speaker
locations for easy product selection.

• Install the speakers in the shelving or cabinets.

2. Test Your Initial Product Installation

A. Select the test products using PSBs or the Control Panel. (See the 903 manual for detailed instructions.)

• On a 903, press the rst key at the top of the column of eight Product Group keys. The red LED comes on.

• Enter the number of the rst product in the Source Group using the numeric pad. The Product Group Display
blinks while receiving your input.

• The Product Group Display stops blinking after two seconds and the selected product comes on.

• Enter the numbers of the remaining test products in their respective Product Groups.

B. Adjust the product controls until you hear program material. If none is heard:

• Check for source material (Satellite receiver, DVD, Blu-ray, music server etc.)

• Check your product selection numbers on the control panel for accuracy.

• Check product connections to the switching modules.

• Make sure all products are receiving power.

• Check all Group, Module, and programming switch settings. Refer to the conguration on the information
boxes and your system plan.

Note: If you make any changes to any module’s switch settings, press the System Reset button on the 980 System Module or
cycle power. In systems with control panels, you can also press “Secure, 88, Secure” on the control panel to reset the system.

This enables the modules to recognize the new settings.

• Make sure that PSBs, if present, are connected to the correct header position.

• If PSBs are not installed, plug a test PSB into the respective headers or use the header shorting method (see
Figure 46 on page 28) on the switching modules to make sure that the products are currently selected to play.

• Follow the signal path visually through the product hookups and system buses to make sure there are
no wiring errors or RCA cables that have been pulled loose. If you still have difculty, call Audio Authority

Technical Support at 800-322-8346.

3. Install the Remaining Products

• Install the rest of the sources, receivers and speakers by groups.

• Check all connections in each product group as it is completed.

30

4. Test All Products

This section covers operation of Access™ Systems using PSBs rather than a Control Panel. For operation of systems

utilizing a control panel, please see the separate User’s Guide included with the control panel.

1. Make sure the system is on (check power lights on switch modules.)

2. Select products to play by pressing the PSBs next to one product in each product group. The PSB lights,
conrming that the product is selected.

3. Adjust product controls to get the desired audio level.

4. Select a new product in any group by pressing its PSB. The previous selection is automatically canceled.
Select every product in each group to be certain all products are correctly installed.

USER TIPS

1. Selecting Additional Speaker Pairs with PSBs

The number of speakers per product group that can play at once is limited by the way you set the speaker

limit on the 980 module. The Access™ System is capable of playing up to four pairs at once, but many

ampliers are not recommended to play more than one pair simultaneously. Read each amp’s documentation
to determine the setting you should use.

• To add a pair of speakers to the pair currently playing, “Long Press” the PSB (press and hold about one
second) for the additional pair you wish to add until both pairs are playing.

TECH TIPS

• To turn any current speaker selection OFF, press its PSB.

• A short press on a new speaker selection cancels all previous selections.

2. Deselecting Products with PSBs

Turn any currently selected product OFF by pressing its PSB. The button light goes OFF. If you deselect an in-line
product, such as an EQ, that product is replaced by a direct signal path if you have installed a bypass (for more
information, see “bypass” in the index.)

3. A/B System Comparison

• A/B comparison may be performed on the 903 or 906G control panels. For detailed instructions, refer to the
control panel User’s Guide.

• When you switch a component such as a source, the Access System (congured with a 980 System module)
engages our exclusive SilenTouch™ circuit to mute the audio level briey (for a fraction of a second) during the
switching process. This feature reduces switching noise.

APPENDIX A: SAMPLE SYSTEMS

These samples can help you in addressing and laying out your system as well as installing the buses and products.
Pick a sample that is similar to your overall system and then ignore any parts that are not applicable. For example,

if your system does not have a control panel, you can still use a sample system layout for comparison. If your

system is stereo only, the connections and addressing scheme is very similar. There are also many drawings
available showing unique product hookups and congurations. If you have any questions, or simply want to verify
your system plans or product hookups, don’t hesitate to call technical support at 800-322-8346 (800-32-AUDIO).

Left & Right Speakers

Model 932 Speaker Modules can be congured to function as left, right or mono modules. The slide switch on the bottom
left side of the module is marked ”Left-Right.” Position the switch to ”Left” for left channel function and ”Right” for either
right channel or mono function (if used for mono operation there will not be a corresponding “L” module.)

932 modules in the Front Speaker Product Group are unique in the fact that they share the same Group Address with the
receiver group. For example, if the Receiver Product Group number is “4”, then the Front Speaker Group number would
also be “4”. All other speaker groups should have a higher Group address.

Left and Right modules have the same Module ID (e.g. for front speakers 1-8 both Left & Right modules would be
addressed: Module ID= “0-9” on the slide switch, and “0” on the rotary switch; Group= 4.
The next module pair for front speakers 9-16 both Left & Right modules would be addressed: Module ID= “0-9” on the slide
switch, and “1” on the rotary switch; Group= 4, etc.)

Denition 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 that system.

The installer sets numeric switches like the ones in Figure 26 on page 17 for each module
that 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 932 and 939 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

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.

Bypass A way to hear a system without a particular in-line component (EQ, Crossover, Amplier,

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 ampliers. 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 bypassed Product Group is deselected, the

audio signal continues through the bypassed group to the next Product Group. To activate
Bypass, nd the last 922 module in the Processor group and turn on its Bypass switch.

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.

46

Module A basic component of the Access™ System. There are ve types of modules normally

found in home entertainment applications:

• Switching Modules or Product Selector Modules select and connect products

for demonstration and communicate with other system components through the
System Bus. Examples are Models 922, 932, 942, 945 955 and 956B.

• 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.

• Control Modules - Examples are Models 970A, 1322D

• Adapters and Converters - Examples are 977 and 979

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 head units, ampliers, subwoofers, etc.

product group also refers to the windows to the right on 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 conrm 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 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.”

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.
