Model 942 Amplifier Selector Module
Model 942 controls four two-channel amplifiers or receivers. One module accommodates both low-level inputs
and high-level outputs. For high current amplifier applications, use 922 for input, but dock a heavy duty 949X
module to it to switch the high current speaker output signals ( See also 939 below .)
Model 945 Receiver Selector Module
Model 945 controls four Surround Sound or Digital Audio receivers. One module accommodates low-level and
Digital Audio inputs and front/center/surround high-level outputs, as well as low-level Subwoofer output. Bus
connections are directional (IN from previous receiver module or previous product group/OUT to next
receiver module).
Model 956 Soundbar Selector Module
Model 956 controls four soundbars, digital-to-analog converters, or receivers (with dedicated speakers). One
module accommodates digital (Toslink®) and stereo analog inputs allowing PCM, Bitstream, Dolby TrueHD and
DTS TruSurround.
Speaker Modules
Model 932 Speaker Selector Module
Model 932 controls one channel (e.g. left or right) of eight speakers. Two 932 modules are required for eight
stereo pairs. Use one 932 for center speakers or speaker level subwoofers.
Model 939 High Current Speaker Selector Module
For high current applications, use 939 in place of 932 switch modules ( See also 949X on page 7 .)
Model 940 High-Level Selector Module
Model 940 controls four speaker pairs, but does not offer SilenTouch
™
or AutoDamping
™
. Use Model 932 for
applications where SilenTouch
™
and AutoDamping
™
are desired.
SINGLE PRODUCT GROUP SWITCHING SYSTEMS
Individual Access Modules
Most products can be switched with a single AccessEZ
™
module, and generally, a 980 System Module. Product Select
Buttons (PSBs) may be installed next to each product or a 906G Single Product Group Control Panel can be used. If
the system is expanded to switch multiple sources, receivers and speakers, the Access
™
system can be modified by
adding the necessary switching modules. This section provides a general overview of system layouts; for detailed hookup
instructions, see Appendix A.
