READ THIS BEFORE YOU DO ANYTHING!
FOUR IMPORTANT CONSIDERATIONS
1. Where is the IR Receiver going to be located? The IR Receiver must be
‘line-of-sight’ to the remote control being used to be able to control the
system audio/video components. This location should be in a convenient
spot in front of the user when seated in a typical location for watching TV
or listening to music. This will determine how the IR Receiver is going to be
mounted.
2. How is the IR Receiver going to be mounted? The IR Receiver can be
surface mounted directly to the frame on the front of some at panel TVs.
For TVs that do not have a wide enough frame, the TV Mount Adapter
can be used to extend the IR Receiver out from the back of the TV. If the
IR Receiver is going to be mounted in a cabinet door, the Flush Mount
AdapterwillmounttheIRReceiverinan11/16”holeinthecabinetdoor.
If the IR Receiver is going to be placed on a shelf or on top of a cabinet,
the Tabletop Adapter provides an attractive, low prole case for that
application.
3. Where are the audio/video components that are going to be controlled?
TheIRReceiver,EmittersandPowerSupplyallconnecttothe789-44
Connecting Block. The Connecting Block should be in the same location
as the audio/video components. If the A/V components are in a wall unit or
cabinet in the same room and within a few feet of the IR Receiver, then once
the IR Receiver has been mounted, nd a convenient location that allows
access to the Connecting Block for making connections and then simply
connecttheIRReceiver,EmittersandPowerSupply.(TheIRReceiverhas
atotalwirelengthof6feet,8inches,andtheEmittershaveawirelengthof
10feet,usuallyenoughwiretomakeconnectionsinatypicalcabinetorwall
unit.)
If the IR Receiver is going to be mounted across the room or in a different
room from the A/V components, the wire length of the IR Receiver can
beextendedtoaccommodatethosesituations.Pleaseseethesection:
Extending the Receiver Wire for additional information.
4. IMPORTANT NOTE - Placement - The IR Receiver should be located so
that it is not directly facing a light source such as sunlight, lamps or video
displays(CRT,LCD,andPlasma).Whenmountednearadisplay,itshould
be ush to the display and away from light reections that may occur.

INSTALLING THE IR RECEIVER
SURFACE MOUNT
The rst, and easiest, option is to mount the IR Receiver on the front frame of a
at panel TV. This application can also be used to surface mount the IR Receiver
to other objects.
1. Select a location on the TV frame to mount the IR Receiver. Be sure the
receiver will not be blocked by any object to allow ‘line-of-sight’ to the
remote control in normal use.
2. WiththeIRReceiver8”RibbonCabledirectedtowardtheedgeoftheTV,

FLUSH MOUNT ADAPTER
The Flush Mount Adapter allows mounting the IR Receiver in an equipment
cabinet door. This allows IR controlled audio/video components to be controlled
with the cabinet door closed.
Thisapplicationrequiresdrillingan11/16”(17.4mm)holeinthecabinetdooras
shown in Figure 9. It is recommended that the IR Receiver be mounted closer to
the hinged side of the cabinet door so the Electronics Module can be mounted
to an inside wall rather than the door.
1. Select a location on the cabinet door to mount the Flush Mount Adapter.
Besurethereisatleastoneinchofclearancefromthebackofa5/8”thick

EXTENDING THE RECEIVER WIRE
In some applications it may be necessary to extend the IR Receiver wire. Typical
examples would be if the IR Receiver is going to be located across the room
from the Connecting Block and A/V components or if the IR Receiver is going
to be located in a remote room. This will give the user the ability to control IR
controlled audio/video components from a location where the remote control no
longer has direct line-of-sight to the equipment.
To extend the IR Receiver wire, cut the Ribbon Cable between the Electronics
Module and the 3.5mm stereo mini plug. To extend the wire run to the
Connecting Block, use a terminal strip to connect the IR Receiver wire to the
wirerunningtotheConnectingBlock.(Figure 17)Useunshielded3-conductor
stranded wire for the extension as detailed on the next page.

MULTI-ROOM APPLICATION
Another application is multi-room IR control. If an audio receiver is being used to
drive speakers in multiple rooms, it may be desirable to place an IR Receiver in
some or all of those rooms. In many cases, this same application can be used to
controlthemainzoneandsecondzoneofatwo-zoneA/VReceiver.
This will allow a user to turn the system ON/OFF with an IR remote via the IR
Receiver(s)intheremoteroom(s).Thesystemcanalsobecontrolledfromthemain
room with an IR remote using the IR Receiver in the main room.
Installation combines the connections described in the previous Single Room
and Extending the Wire sections. The Main Room IR Receiver gets connected

IR Troubleshooting Guide
NOTE: Due to the many variables in a given installation, the troubleshooting
measures you may need to take can vary in different situations.
Each installation is different due to the number of IR Receivers, length of wire
runs, type of wire, amount of ambient IR noise present, etc….
Therefore, your troubleshooting measures for a particular job can range from
nothing at all, to any combination of the solutions listed below.
Symptom #1: DIM or NO Talkback LED during IR reception or reduced
operational range.
Cause Solution
1. Weakbatteriesintransmitting
remote.
Replace batteries.
2. Bad Emitter or no Emitter
plugged into Connecting Block.
Test Emitter and verify wiring.
3. Signal wire between IR Re-
ceiver and the Connecting
Block is open.
Recheck wiring.
4. Power Supply not putting out
proper voltage.
Verifysupplyisa12VDCregulated
supplyreadingbetween11.5to
13VDCunderload.Usetheincluded
PowerSupply,Model781ERGPS
(12VDCRegulated,200mA)or
782ERGPS(12VDCRegulated,
1.2A)
5. Output from the IR Receiver/
Connecting Block is connected
to a high impedance IR input
jack on a component.
If you are using a passive Con-
nectingBlock,suchasa789-44,
and the system is not working, try
the amplied Connecting Block,
model791-44.Putoneofthesmall
plastic case jumpers supplied with
the block on the pins next to the
Emitter jack. This will provide the
IR-in jack on the component with a
hotter signal.
6. IR Receiver is inoperable. Replace IR Receiver.

®
15
Symptom #2: Talkback LED on IR Receiver (and/or Emitters) dimly lit or
flickering.
Cause Solution
1. Signal and ground wires are
reversed or shorted either at
the Connecting Block or IR
Receiver.
Recheck wiring.
2. Defective Emitter. Replace Emitter.
3. Relatively high levels of ambient
light noise. This can be due to
anyofthefollowing:sunlight,
orescent lighting or Plasma
Displays.
Reposition the IR Receiver away
from the light source or eliminate
the light source.
4. EMIinducednoise(electromag-
neticinterference).Thiscanbe
due to light dimmer controls
or other radiating electronic
devices(PC’soranypoorly
shieldedelectronicdevice).
Reposition the IR Receiver and/or
cabling away from emitting device.
Youcanalsoplacea470-ohm
resistor in parallel with the IR Signal
andGNDconnectionsontheCon-
necting Block. This will also help
alleviate any stray capacitance in
the cable.
5. Plasma Interference. Plasma interference can be re-
ected off of any item it comes into
contact with within approx. 3 feet
of the front of the display. Keeping
this in mind, make sure that the IR
Receiver is free from any object that
might reect Plasma interference
into the receiving eye.

16
Symptom #3: Talkback LED on IR Receiver (and/or Emitters)
constantly on.
Cause Solution
1. Plasma Interference Plasma interference can be re-
ected off of any item it comes into
contact with within approx. 3 feet
of the front of the display. Keeping
this in mind, make sure that the IR
Receiver is free from any object that
might reect Plasma interference
back into the receiving eye.
2. VoltageandGroundwiresare
reversed at the Connecting
Block or IR Receiver
Recheck wiring.
3. Relatively high levels of ambi-
ent noise. This can be due to
anyofthefollowing:sunlight,
orescent lighting or Plasma
Displays.
Reposition the IR Receiver or elimi-
nate the light source.
4. EMIinducednoise(electromag-
neticinterference).Thiscanbe
due to light dimmer controls
or other radiating electronic
devices(PC’soranypoorly
shieldedelectronicdevice).
Reposition the IR Receiver and/or
cabling away from emitting device.
Youcanalsoplacea470-ohm
resistor in parallel with the IR Signal
andGNDconnectionsontheCon-
necting Block. This will also help
alleviate any stray capacitance in
the cable.
5. Power Supply not putting out
proper voltage.
Verifysupplyisa12VDCregulated
supplyreadingbetween11.5to
13VDCunderload.
Symptom #4: Talkback LED on IR Receiver blinks but 283D Emit-
ters do not.
Cause Solution
1. There may be a short, such
as a staple driven through the
SignalandGNDwiresoftheIR
Receiver and/or the Emitter.
Recheck wiring.
2. Emitter may be shorted inter-
nally
Replace Emitter or use TEST EMIT-
TER to check circuit.

Symptom #5: Intermittent IR control (i.e. buttons on remote
need to be pressed multiple times)
Cause Solution
1. Plasma Interference. Plasma interference can be re-
ected off of any item it comes into
contact with within approx. 3 feet
of the front of the display. Keeping
this in mind, make sure that the IR
Receiver is free from any object that
might reect Plasma interference
back into the receiving eye.
2. Relatively high levels of ambi-
ent noise. This can be due to
anyofthefollowing:sunlight,
orescent lighting or Plasma
Displays.
Reposition the IR Receiver or elimi-
nate the light source.
3. LongWireRuns–shieldedwire
typicallyof100feet(30meters)
or longer causes a lter effect
due to accumulated capaci-
tance of the wire. Intermittent,
or no IR control, could actually
be because of the longer wire
runs.
Puttinga470-ohmresistorinparal-
lel at the Connecting Block between
signal and ground will effectively
discharge the capacitance of the
wire. This will allow the signal to
travel farther on shielded wire.
Adding a resistor between the input
and ground of the Connecting Block
will drop the IR level down some-
what. Passive Connecting Blocks,
suchasthe789-44,maynothave
enough signal output for consistent
controloftheequipment.Youmay
have to upgrade to an amplied
Connecting Block to bring the IR
level back to normal. In these
cases,the791-44wouldbeanideal
ConnectingBlockforsinglezone
systemswhilethe795-20would
workbestfora2-4zonesystem.
4. Low batteries in Remote Replace batteries.

Symptom 6: Emitters function but some (or all)
components do not respond.
Cause Solution
1. Emitter placement is incorrect. Reposition the Emitter so that it is
directly over the component’s IR
eye. Shine a small ashlight into the
front panel of the component to lo-
cate the eye or consult the compo-
nent’s owner’s manual for the exact
location of the IR eye.
2. Emitter placement is correct but
the signal is overpowering the
unit or there is bleed-through
from other Emitters close by.
Reposition the Emitter so it is not
directly over the IR eye to reduce
the amount of IR signal the IR eye
on the component being controlled
‘sees’. If the components do not
need to be controlled directly
without an IR Repeater system
(componentsarelocatedinan
equipmentcloset),placeaMouse
Emitter Shield cover over the
Emitter(PN#MS1).Therounded
(non-stick)sideoftheEmitterisa
hi-output side and can reect off
other devices and overpower some
components’ IR Sensors.

Symptom #7: Absolutely No Functionality
(How to determine which component is at fault)
Component to Test Instructions
1. Verify Power Supply WithaMultimeter,measuretheDCVoltageof
the Power Supply while it is connected to the
Connecting Block. Put the negative lead of the
meterontheterminalmarkedGNDandthe
positiveleadontheterminalmarked12VDC(or
V).Youshouldgetareadingbetween11.5VDC
and13.0VDC.Ifnot,removethesupplyfrom
the Connecting Block and measure again -
this time directly on the 2.5mm coaxial plug.
Ifitreadsbetween11.5VDCand13VDC,the
Power Supply is most likely good. Reconnect
to the Connecting Block and proceed to Step
2. NOTE: In most cases this will indicate the
Power Supply is good but in some cases the
PowerSupplycanstillbebad(i.e.readsgood
when not plugged in but may not be able to
handlethecurrentloadofthesystem.)
2. VerifyEmitter.(283D
or286DBlinkStyle
ONLY)
Remove the Power Supply from the Connecting
Block and all Emitters from the output. Place a
jumper wire on the Connecting Block between
IRand+12V.ReconnectthePowerSupplyand
one Emitter. The Emitter should light bright and
solid. Repeat for all Emitters.
3. Verify IR Receiver. Remove the Power Supply from the Connect-
ing Block and all Emitters from the output.
Place a jumper wire on the Connecting Block
betweenIRSignalandGND.Reconnectthe
PowerSupply.Withaknowngoodhand-held
remote, shoot a constant IR Command at the
IR Receiver and verify the Talkback LED on the
IR Receiver ashes.
