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 AccessEZSystem. 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.
