KP 1
Step One – Prepare and Install the Wiring
You will need to prepare an appropriate length of CM- or CP-rated Category 3 or
Category 5 UTP, 8-pin, 8-conductor wiring. For runs over 250 feet, thicker CL2/CL3,
4-pair, 22AWG wire may be required to preserve signal integrity.
Connect the KP 1 to the PA 4000 using standard T568B Straight Through wiring.
Looking at the connector with its clip down and the wires coming out of the connector
toward you, numbered from left to right, the typical pin assignments are as shown in
Wiring Chart 1 and Figure 1.

holes accept the screws supplied with your Decora-style cover plate to attach it to
the KP 1.
Wiring Chart 1
™ Mounting Screw Slots – Use the supplied machine screws to attach the KP 1 to
an electrical junction box or plaster ring using these slots.
£ RJ-45 Connector – Insert one end of the RJ-45 connector for the cable connecting
the KP 1 to the PA 4000 into this left-facing jack. When the other end of the cable is
plugged into the appropriate jack on the PA 4000, the cable carries control signals gen-
erated by the KP 1 and the signals received by the optional IR sensor to the PA 4000,
and a +12 Volt power supply from the PA 4000 that powers the optional IR sensor,
when installed.
¢ 3-Pin IR Sensor Terminal Block – When installing an optional IR sensor, connect
it to the appropriate terminals. Connect the sensor’s three conductors to the Ground, IR
Signal Output and +12V DC terminals by slightly unscrewing each of the set screws
shown, inserting the bare wire end into the downward-facing hole under the set screw,
then tightening the set screw. The terminal block is internally connected to the RJ-45
Connector £.

Figure 1
Either the striped or solid color standards may be used, depending on the type of cable
being installed. Make certain that the same color wire is connected to the same pin
number at each end of the wire. Make sure that the twisted pairs of wires consist of
those attached to pins 1 and 2, pins 3 and 6, pins 4 and 5, and pins 7 and 8.
When attaching the connectors to each end of the cable, strip the outer insulation
jacket about 1-1/2" to 2" from the end. The cable is constructed of four twisted pairs
of wires. Flatten the wire ends to prepare them for insertion into the connector. Then
trim the wire ends to approximately 1/2" in order to leave as little untwisted wire as
possible. Fully insert the wire into the connector. Carefully crimp the connector in accor-
dance with the connector manufacturer’s instructions, making sure that each wire is
securely fastened in the connector and that no insulation is caught in the connector. If
using stranded conductors, make sure that there are no loose strands.

IR Sensor Cutout – If you will be installing an optional IR sensor, punch out this
cutout. See the detailed installation instructions in the next section.
Before making any connections to the PA 4000, be certain that it has been turned off
and unplugged from the AC outlet.
Home-run the cable from the KP 1 to the PA 4000. Insert the RJ-45 connector on the
cable into the RJ-45 Connector £ on the back of the KP 1 until it clicks into place.
The connection to the PA 4000 and appropriate configuration of the PA 4000 are
described in Step Four.

Step Two – Install an Optional IR Sensor
If you are installing the optional IR sensor, you also need to prepare the sensor’s ribbon
cable. The recommended Xantech 490-00 Micro Link comes with a 7-foot long, 3-con-
ductor ribbon cable. Trim the ribbon cable to 3 or 4 inches. Strip the wire ends 1 to
1-1/2 inches, then fold each bare end over itself twice and twist it. This creates a slightly
thicker wire to connect to the KP 1‘s IR Sensor Terminal Block 4. Break out the
IR Sensor Cutout 5 on the front of the KP 1 by gently pressing out, and insert the
Micro Link sensor through the hole from the front, cable end first. Install the sensor’s
nut on the threaded body of the sensor before connecting the ribbon cable to the
KP 1’s terminal block. Tighten the nut to secure the sensor in its cutout.

Step Three – Install the KP 1 In the Wall
Although the KP 1 is designed to fit into a standard single-gang electrical junction box
or plaster ring, always check the fit before cutting into a wall. Follow these guidelines
for optimal placement of the KP 1:
d Remote Keypad Inputs
e Bridge 1 Amplifier Mode Switch
f Bridge 2 Amplifier Mode Switch
g Power Control Mode Switches
h Volume/Output Level Controls
CAUTION: THE ELECTRICAL JUNCTION BOX IN WHICH THE KP 1 IS MOUNTED
MUST BE DEDICATED TO LOW-VOLTAGE CONTROL SYSTEM APPLICATIONS. MAKE
SURE THAT NO AUDIO/VIDEO OR AC MAINS WIRING PASSES THROUGH OR TER-
MINATES IN THIS BOX!
Step Four – Connect the KP 1 to the PA 4000
If you install the optional IR sensor, avoid placing the KP 1 in an area subject to poten-
tial interference with the IR signal.
Locate the KP 1 at least 4 inches from a dimmer switch, or install it inside a metal box
rather than plastic, as the dimmer switch may generate electronic noise that might
interfere with the KP 1.
The KP 1 may be installed in a multi-gang junction box with other low-voltage controls.
Please refer to Figure 3 for guidance in installing the KP 1 into a junction box and
attaching a Decora-style cover plate.
• When the PA 4000 is used in the Normal mode, feeding four pairs of speakers, con-
nect the cable from each KP 1 to the Remote Keypad Input d corresponding to
the proper speaker channel for that room.
• When the PA 4000 is used in one of the Bridged modes, connect the cable from the
KP 1 to the Remote Keypad Input d corresponding to the lower numbered jack
for the pair of channels being bridged. Thus, when Output Channels 1 and 2 are
bridged, connect the KP 1 cable to the Remote Keypad Input d connector for
Channel 1. When Channels 3 and 4 are bridged, connect the KP 1 cable to the
Remote Keypad Input d connector for Channel 3.
• The proper Remote Keypad Input d connections are determined by whether
the amplifier channels are used in their Normal mode or if they are bridged. Use of a
separate input source for Channel 3 does not impact the keypad connections.
• When a KP 1 is connected to any Remote Keypad Input d, the Power Control
Mode Switch g for that channel must be placed in the far right position, under
the words “ON/KEYPAD” to enable the KP 1’s Power Button 3 to turn on the
PA 4000.
Gently place the KP 1 in the junction box or plaster ring and attach it by inserting the
supplied mounting screws through the Mounting Screw Slots ™ of the KP 1
until it is aligned correctly and tighten the screws.
Attach a Decora-style cover plate (not included) by placing the screws provided
with the cover plate through the plate’s holes and into the KP 1’s Cover Plate
Screwholes ¡. Hand-tighten the screws so that the cover plate is secure, taking care
so as not to overtighten and break the cover plate. Although any color or compatible
style of wall plate may be used with the KP 1, the KP 1 itself should not be painted,
in order not to cover the printed button labels.

When the optional IR sensor is installed, connect the PA 4000’s IR Remote Control
Output a to the IR input jack on the rear panel of the component to be controlled.
IMPORTANT: When a KP 1 is used with any channel on the PA 4000, DO NOT connect
a remote sensor or other device to that channel’s Remote IR Sensor Input c
unless you are using multiple, cascaded PA 4000 amplifiers and KP 1’s with IR sensors,
as explained below.
Setting Turn-On Volume Level Limits
The PA 4000 is equipped with a turn-on volume level limiter in order to prevent
possible disturbances or damage to equipment. Normally, when any channel pair of the
PA 4000 is turned on, it will play at the volume setting in use at the last listening
session. However, the level will automatically be limited to either the factory-preset limit
of –12dB, or to a user-determined limit. The KP 1 allows you to set or reset the volume
level limit from the remote location.
The PA 4000 will process and forward IR commands received from a Remote IR
Sensor Input c or a Remote Keypad Input d in the order in which they are
received. For example, when four KP 1’s with optional IR sensors are used with four
separate channels and two rooms send an IR command to control the same AVR at the
same time, the second signal received by the PA 4000 will be held until the first
sender’s command has been forwarded to the AVR for processing.
Two people are needed to complete this procedure, as adjustments must be made to
the KP 1 and PA 4000 at the same time.
1. With source material playing, move the Power Control Mode Switch g for the
channel being adjusted to the middle “MUSIC SENSE” position.
2. Use the KP 1 in the remote room to set the volume level to the desired turn-on vol-
ume limit – that is, the loudest desired turn-on level – by holding down the Power
Button 3 while simultaneously adjusting the Volume Controls 4.
3. After releasing the keypad buttons, return the Power Control Mode Switch g
for the channel being adjusted to the “ON/KEYPAD” position.
The PA 4000 is also capable of being used with compatible multiroom-equipped
Harman Kardon A/V receivers, using the KP 1 commands to power the AVR’s multiroom
output on or off, while controlling the volume using the PA 4000. To enable this fea-
ture, slide the PA 4000’s MR On/Off Command Switch b to the left so that it is
over the word “ON.” You must connect the PA 4000’s IR Remote Control Output
a to the IR remote input of the AVR in order for this function to work.
To reset the Turn-On Volume Level Limit to the factory preset of –12dB:
1. With source material playing, move the Power Control Mode Switch g for the
channel being reset to the middle “MUSIC SENSE” position.
2. Simultaneously press the KP 1’s Power and Volume II Buttons 34.
3. After the KP 1’s buttons have been released, return the PA 4000’s Power Control
Mode Switch g for the channel being reset to the “ON/KEYPAD” position.
Notes on Using KP 1 with Cascaded PA 4000’s:
1. When multiple PA 4000 amplifiers are cascaded together, each amplifier may use
separate KP 1’s even though all are fed with the same audio source. Connect the
KP 1’s to each amplifier as described above.
2. When IR sensors are used with multiple amplifiers, daisy-chain the IR Remote
Control Output a of each PA 4000 to one of the Remote IR Sensor Inputs
c of the PA 4000 immediately prior to it in the audio signal chain. However, note
that if an IR command is transmitted simultaneously from any of the downstream
amplifiers and from the KP 1 connected to the channel used for the Remote IR
Sensor Input c, the two commands will be garbled.
3. When multiple, cascaded PA 4000’s are used with a Harman Kardon A/V receiver
that has multiroom-control capability, it is recommended that you slide the
MR On/Off Command Switch b for each PA 4000 in the system to the
“OFF” position. Otherwise, when the last channel of any PA 4000 in the system is
turned off, that PA 4000 will signal the AVR to turn off, regardless of the status of
the other PA 4000’s in the system.
Troubleshooting
If your PA 4000 is not responding to button presses of the KP 1:
• Check the wiring for the cable connecting the KP 1 to the PA 4000. Make sure it is
Straight Through T568B cable, as described in Step One.
• Make sure the PA 4000 has been plugged in and is powered on.
• Make sure that all audio components are properly connected to the PA 4000 and
sending an audio signal to the PA 4000.
• Make sure that a remote control is not simultaneously sending signals to an IR sensor
that has been connected to the PA 4000’s Remote IR Sensor Input c for the
same channel as the KP 1.
If the component intended to receive commands from an optional IR sensor installed in
the KP 1 is not responding:
• Make sure that the component is plugged in and its master power switch is
turned on.
• Check the connections between the IR sensor and the KP 1’s IR Sensor Terminal
Block ¢.
• Check the connection between the PA 4000’s IR Remote Control Output a
and the IR remote control input of the component to be controlled.
• Make sure that another remote control is not simultaneously sending signals to an IR
sensor connected to the PA 4000’s Remote IR Sensor Input c for the same
channel as the KP 1.
Operation
Turn on the PA 4000 by pressing its power switch. This will cause the Standby indicator
for the channel pairs selected using the Power Control Mode Switches g
to light.
Turn the PA 4000’s channel pairs on or off in response to presses of the corresponding
KP 1’s Power Button 3.
Adjust the initial reference output levels for your system using your receiver or
preamp/processor’s controls. Do not use the Volume/Output Level Controls h
on the back of the PA 4000.
For subsequent listening sessions, you may raise or lower the volume levels in the
remote listening location by pressing the KP 1’s Volume I or I 4 buttons.
When an optional IR sensor has been installed, at any time during the listening session,
point the transmitting end of the previously selected component’s remote control
toward the sensor mounted in the KP 1, and press the remote’s buttons to transmit the
desired command to the PA 4000, which forwards the command to the component.
If your component is equipped with an IR remote output that is connected to one or
more additional components, these may also be controlled using the sensor mounted
in the KP 1.
