5.32 Front Panel IR Flood Emitter
All S4.3 Controllers are shipped with the
front panel IR “flood” emitter engaged.
However, there may be applications
(system installations on open shelves in
very large, bright rooms, for example)
where the IR “flood” emitter might
interfere with proper source component
operation or will not be particularly
effective in communicating control
pulses.
To disable the IR “flood” emitter, remove
the jumper wire between screws 2 and 3
of the TX FORMAT terminal block located
on the lower right hand side of the S4.3
Controller’s rear panel.
5.33 Rear Panel IR Emitters
The S4.3 Controller rear panel has four
paralleled 3.5 mm mini-jack sockets
labeled "TX OUTPUTS-WE". These accept
the QED window emitters (Order Code
RL-WE).
Use these optional IR window emitters in
situations where the S4.3 Controller is
located some distance away from the
source components or where the IR
“flood” emitter may have difficulty
transmitting reliable source control data.
•
Each IR window emitter is fixed to the
front of the source component by means
of an adhesive. It is very important that
the window emitter is located over the IR
receiver of the source component
(normally behind an acrylic panel). If you
are unsure about the location of the
receiver, send a control code from a
keypad or RHS in a remote zone while
slowly moving the window emitter over
the front panel of the source component.
Once reliable operation is obtained note
the position and affix the window emitter.
NOTE:
•
The adhesive backing should be
removed whilst locating the receivers
“sweet spot”.
5.4 Advanced Multi-Zone
Systems
5.41 8 - and 12 - Zone Systems
The S4.3 Controller is designed to supply
independently controlled sound to four
separate zones. In many instances, a
complex system may require even more
flexibility. To satisfy these requirements,
typically two or three S4.3 Controllers
may be cascaded to form an 8 to 12
independent zone system. Under these
circumstances, all S4.3 Controllers can
still use only one set of source
components.
5.42 Large System Configuration
Should more than three controllers be
required, then this is possible provided
that care is taken to ensure that all
controllers are adequately supported and
ventilated. It is important to ensure that
no more than three controllers are
physically stacked on top of one another.
The following examples explain how two
or three S4.3 Controllers can be linked
together. The same principles apply for
larger systems employing more than
three Controllers.
All hookup instructions will assume that
zones 1-4 will be handled by the bottom
S4.3 Controller (“A”), zones 5-8 by the
S4.3 Controller immediately above it
(“B”) and zones 9-12 by the top unit
(“C”).
Remove this jumper to disable
front panel IR flood emitter.
Optional remote IR
emitters for use in lieu of
front panel IR flood emitter.
