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, find “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 configurations
for a 2-channel display including several sources, receivers, and
stereo speakers. The architecture of Access
™
makes it possible
to design a system that fits 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 configuration.
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.
