5.1 A.C. Line Considerations
5.11 A.C. for the S4.3 Controller
Connect the S4.3 Controller to an unswitched
a.c. source only.
5.12 A.C. for Source Components
At the rear of the S4.3 Controller is a switched
a.c. mains outlet. This can be used to power
source components in installations where the
user wants to power down source
components from a remote zone.
Switched a.c. outlet: When the front panel
switch of the S4.3 Controller is Off, the
switched a.c. outlet is also off. When the front
panel switch is turned On (i.e., when the S4.3
Controller first powers up to “Standby”
mode), the switched outlet remains off until
the S4.3 Controller receives a zone activation
command.
The switched a.c. outlet then remains on until
the front panel power switch is turned Off or
the S4.3 Controller receives a “power down”
command from a remote zone (STBY
command sent for >3 seconds).
5.13 Multi-Controller Control Link
In a multi-controller system, the Control Link
enables the control of all S4.3 Controller
switched a.c. outlets from any zone on any
controller. It is also possible to turn all zones
off from a single zone on any controller when
this link is in place.
Each controller has two 3.5 mm sockets
marked CONTROL LINK IN and CONTROL
LINK OUT on the back panel. To enable the
enhanced a.c. link, connect the CONTROL
LINK OUT socket on the first controller to the
CONTROL LINK IN socket on the second unit.
If appropriate, connect controllers 2 and 3 in
the same way.
CAUTION
To interconnect CONTROL LINK IN and
CONTROL LINK OUT sockets, either obtain a
STEREO 3.5 mm jack plug interconnect lead
from QED or make up suitable leads.
If making up leads, DO NOT USE MONO
LEADS OR PLUGS. Only the TIP and INNER
RING of the stereo jack plugs should be
connected - DO NOT connect the OUTER
ground/earth.
5.14 External Control of Switched
A.C. Mains Outlets.
When external control of the a.c. outlet is
required, connect terminal 6 of the TX
FORMAT connector on the back panel to
terminal 1 (ground). In a multi-controller
system, terminal 6 of the TX FORMAT
connector on each controller must be daisy
chained using suitable hook up wire to enable
full remote control of a.c. switching.
If the pins 1 and 6 are shorted, all controller
a.c. outlets are switched On permanently and
the “power down” command has no effect. If
the external control signal to terminal 6 is
switched Off, the a.c. outlet(s) will be turned
Off unless any zone of any controller is On. In
this case, the a.c. outlet(s) will remain on.
5.15 A.C. Power Recommendations
a) When using the switched mains a.c. outlet to
supply source components it is
recommended that a mains distribution unit
be used with the IEC plug supplied.
b) Ensure that the total power consumption of
all the source components connected to each
switched a.c. outlet does NOT exceed 400W.
c) Power amplifiers are not suitable for
connecting directly to the controller's
switched a.c. mains outlet.
d) Source components featuring a standby
mode i.e. a soft toggle Power On/Off button
should not be used with the switched
controller a.c. mains outlet.
5.2 Source Component Setup
NOTE: Equipment manufacturers change
their remote control systems from time to
time. It is therefore advisable to check the
operation of a source component with the
S4.3 Controller before specifying.
If you encounter any compatibility problems
with the supported components listed in 5.22,
please notify QED using the FAXBACK page
in this manual. This will enable us to check
that you have the latest software, and also to
provide codes for these components in the
future.
