Audio Sources
Use a 922 Low-Level module for every four CD players, music servers, or satellite radio receivers you plan to
include in your switching system ( Figure 10 ). Connect each source to a 922, and connect the system bus and
low-level bus from the 922 module to the “Bus In” jacks on the 980 System module. Connect an RCA patch cord
from the low-level “Bus Out” jacks on the 980 to the CD input of a dedicated receiver and add a pair of speakers
to complete the display. To add more sources, add 922 modules. For example, to add sixteen sources, connect
system bus and low-level bus from the first 922 to four more 922 modules.
TV Soundbars
Use a 956B module ( Figure 11 ) for every four soundbars to be demonstrated. The HDMI video from the source
connects to the TV. The 956B switches any digital audio format including Dolby®. To add soundbars to your
display, add 956B modules. For example, to add eight soundbars, add two 956B modules. Connect all modules
with system bus, and all 956B modules with audio/video bus. Be sure to follow signal flow when connecting bus
jacks labeled IN/OUT.
Surround Receivers
Use one 945 module for the input/output for every four receivers ( Figure 12 ). The analog audio bus connects the
dedicated source to the 980 module, and from there it links all the 945 modules in the receiver group. Be sure
you properly connect the bus according to signal flow. The digital audio bus comes directly from the dedicated
source to the 945 module’s IN jacks. 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 12 receivers to a surround switching system, add three 945 modules.
