IR Distribution Systems
IRBKIT
The classic in-cabinet solution that puts your remote back
in control and routes IR commands to wherever they are
needed. This unit can be expanded to provide a solution
to almost any IR control problem. Multiple input/output
options are available and you can add extra receivers and
emitters as required (see p28~29 for more details). It is
available ready to use in a number of configurations:
Basic Kit
This kit, comprising the Keene IR Distribution Amplifier,
240V UK mains power adaptor, 2 x universal emitter
wands IRUW and instruction leaflet. Requires input device
or IR receiver (not included).
Basic Kit Plus Standard
Receiver
This is a complete kit, comprising the Keene IR
Distribution Amplifier, 240V UK mains power adaptor, 2 x
universal emitter wands IRUW, 1 x Standard IR receiver
IRSR and instruction leaflet. (HINT – This is far and away
our most popular kit so if you’re wondering where to start
this is a really good choice. You can easily add to it and
expand the system later if needed.)
Basic Kit plus
Panel Mount Receiver
This is a complete kit, comprising the Keene IR Distribution
Amplifier, 240V UK mains power adaptor, 2 x universal
emitter wands (see output component [IRUW] page 28),
1 x Panel Mount IR receiver and instruction leaflet.

IR Signals Explained
I think we are all aware that infrared is just light that we
cannot normally see. It is light at the low (red) end of the
visible spectrum, and shares many of the properties of
visible light. Like visible light infrared travels in straight lines
and will not go around a corner unless there is something
about that will reflect it or refract it. Also like visible light it
is reflected by white surfaces and usually absorbed by dark
surfaces.
It is worth noting that IR emitter LEDs, the sort of thing that
is used in remote controls etc, are like a torch and they have
a narrow beam, and will only “shine” onto a narrow area. A
10 or 15-degree beam width is not unusual.
When you press a button on your remote control a
microcontroller switches the IR emitter on and off very
quickly in a predetermined sequence. This stream or
sequence of IR “data can contain up to as many as 50
digits. The IR receiver on the equipment you are controlling
picks up this IR data, sends it to its microcontroller to be
decoded and responds accordingly - or at least it should do!
Why on earth would I want to get an IR distribution
amplifier?
With an ever increasing number of set top boxes, media
streamers, switchers and recorders etc it is often convenient,
in fact sometimes essential for domestic harmony, to be
able to locate much of the equipment in a small room or
cupboard out of sight. Unless you want to get up and go
to the cupboard / room / loft or wherever every time you
want to change the channel or volume, you will ideally need
some means of controlling all this equipment from your
armchair. This is where an IR distribution system comes in.
An IR distribution system is basically expected to receive the
IR signal and then send it out or “emit it” again in another
location. Over the years they have evolved and improved,
and now the IR receiver, the distribution amplifier and
the emitter are usually separate components. The receiver
can be positioned where you find convenient – usually
somewhere near to the display. The receiver picks up the
signal from your remote and sends this to the distribution
amplifier which in turn sends it back out as IR to one or
more emitters to control the equipment. The net effect is
that you can control your hidden equipment as easily as if
you were pointing the remote directly at it.
There are many ways in which the receiver can be
connected to the distribution amplifier, including dedicated
cable, RF aerial cable, wireless (radio) or even an IP
computer network. We hope that you can use this guide to
see what systems are possible and select the right products
to make your own AV system easy for everyone to control.
IRUW
IRFSW
IRHPW
The IR Universal wand is for use in low power output and can
be mounted directly on the equipment fascia or positioned on
the shelf.
(optional). A slim, short range emitter for direct attachment to
the equipment fascia.
(optional). A very directional high power long range emitter
for use where the IRUW has insufficient range
IRDW
A single jack plug drives a pair of wands that affix directly
to the equipment fascia and give a visible flash as the IR
signal is emitted
IRSR IRWBR
The standard IR
receiver, supplied
with the IRBKITS
(optional) wideband
IR reciever
or or
IRPMR KIRA
(optional) Panel mount
IR receiver
(seperate system). Use
IR output from KIRA
family of products via
LAN or internet
or
There is one output for driving wands to high power.
High power wands can be used to control equipment
located up to 10m away.
The main body of the IR distribution amplifier is usually located out
of sight or within the AV cabinet. It operates from 12v DC allowing
for easy integration in marine or travel installations, a mains to
12v adaptor is supplied.
There are four outputs for driving wands at
low power. Low power wands are usually
placed inside a cabinet and aimed directly
at the AV equipment

the output direct from a
wireless IR sender such
as the Powermid

A simple splitter such as the
KA109 may be used to combine
two sources of IR input.
