Module A basic component of the Access
™
System. There are five 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, amplifiers, 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 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
demonstration.
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.
