Russound CA4 System Installation Manual
Linking Two Controllers
Two CA4 controllers can be linked together for a system that supports eight
zones and four sources. This setup requires two controllers, a CAT-5 linking
cable, RCA "Y" adapters, two wall ports (CA4-WP), and up to eight keypads
(CA4-KP).
Establish four zones for the rst controller and four zones for the second
controller (keypads and speakers). Arrange the zones on each controller with
an aim toward potential source grouping. Give the customer a list of which
zones are on each controller. Source grouping is specic to the controller the
zone is connected to. Zones cannot be grouped across two controllers.
CONTROLLER CONNECTIONS
Connect the audio from the sources (up to four) to both controllers. The audio
must be split using RCA “Y" adapters to connect to both controllers. It is not
necessary to link the IR outputs. The IR communication is carried to the second
controller via the linking CAT-5 cable.
Refer to the diagram below for connections.
