HOME THEATER SWITCHING SYSTEM
Designing Your Own Application
This section explains the basic switching configurations 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 five or more speaker pairs because they will automatically prevent unselected pairs
from vibrating sympathetically with the selected pair (AutoDamping
™
).
Video Signals
For demonstrating multiple video displays or projectors using HDMI, use our HDMI distribution amplifiers. If your
merchandising plan requires HDMI video switching, Audio Authority can provide a customized 970A-1 to interface
with an HDMI switch. See audioauthority.com/hdmi-demo for details.
