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 902, 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, 922, 932, 942 and 958.
• Expander Modules add channel capacity to switching modules. Examples are
Models 920X 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 902/903 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. 2. 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.
