Homerun
The 50’ CAT distribution line supplied with the base kit should be sufficient as the
homerun for almost all installations. It may be replaced by a longer CAT cable
to the first emitter without excessive loss or impact privacy signal level difference
between the first and last emitters on the line. Theoretically a CAT coupler and
additional cable could be used rather than a longer homerun but this is not the
preferred method due to the coupler most likely being located in an inaccessible
and/or undocumented location, possibly complicating future servicing.
Emitter cable (interconnects) configuration
The interconnects should be connected the same as in a conventional CSM Qt
masking system, i.e. in a series serpentine layout. This will assure that adjacent
emitters are on different channels to minimize any phase interference issues.
CSM’s Quiet Technology uses four distinct non-correlated sounds that repeat every fourth emitter
automatically. The homerun from the controller to the first emitter may be concealed in a wall stud
space.
How CSM emitter cabling works – homeruns and daisy chaining
Emitters on each line are daisy-chained in series during installation. Each emitter has passive internal
logic which rolls over its input channel to a different channel at its output port. Thus every fourth emitter
is actually operated in parallel with the first.
