5.48 A.C. Connections
In systems using multiple S4.3
Controllers, ensure that the controllers
are powered from a suitably rated mains
outlet. Ensure when using a mains
distribution unit that it has a high enough
capacity for the total number of
controllers and source components.
If you wish to control the a.c. mains
supply to the source components then
this is possible using the switched outlet
on each of the controllers. Each outlet has
a 460W capacity which must not be
exceeded. It is possible to connect all
source components to one controller
switched a.c. outlet if within the 460W
rating. Alternatively source components
can be connected to different switched
a.c. outlets in a multiple controller
installation provided that the Control Link
detailed in Section 5.13 is in place.
5.49 Engaged Operation
When a single S4.3 Controller is used, the
DMS module lets the user know when
two zones are listening to the same
source by changing the first character of
the source description from upper case to
lower case i.e. from “Cd” to “cd”.
This is a polite message to let the user
know that if they change tracks or skip
channels it will do so in two or more
zones.
When multiple controllers are used this
feature is still operational, but only
indicates the engaged status for the
zones connected to any one controller.
This means that a zone connected to
controller A and a zone connected to
controller B, listening to the same source,
will not indicate “engaged”.

Use this jumper arrangement in a system with 3 Super
Controllers to disable the flood IR emitters on the first
two Controllers and enable the emitter on the third.

5.45 IR Repeater Connections
Use the following connection guide for
multiple S4.3 Controller systems:
a) For 5-8 zone systems (two S4.3
Controllers): Connect all IR repeaters to
only S4.3 Controller “B”.
b) For 9-12 zone systems (three S4.3
Controllers): Connect all IR repeaters to
only S4.3 Controller “C”.
5.46 RC-5 Bus Connection
Some source components feature an “RC-
5” phono socket for sending and receiving
commands. If for example you wish to use
an RC-5 tuner it may not have its own IR
receiver. If this is the case then the only
way of sending commands to the tuner will
be via the RC-5 phono socket on its rear
panel. To connect the tuner to the controller
take a single phono lead and from the RC-5
socket on the controller to the RC-5 IN
socket on the tuner.
NOTE: The Audio lead must be
connected from the tuner to the
controller for this link to work.
5.47 IsoLink Connection
Some source brands such as Pioneer
feature an IR CONTROL BUS similar in
operation to the RC-5 Bus detailed in
section 5.46. QED can supply an optional
adapter called IsoLink which enables
equipment fitted with a suitable 3.5mm
Bus socket to be controlled via an IR TX
Output on the controller. All instructions
are supplied with the adapter.
