1.) Line Outputs (Left & ight) - These are dual RCA line outputs to go to additional amplifiers or
to powered sub-woofers. The white one is for left channel and the red one is for right channel. These
outputs will react to the volume controllers for each zone. Any changes made to these will follow
through to these outputs.
If you need additional speakers, say for a deck or large family room and require more power than
onboard, simply take these outputs and plug into the larger amp. If you want to run sub-woofers in
a zone, you can use powered sub-woofer systems or an additional amp to power them as in the above
e planation.
2.) Speaker Connectors - These connectors are where the speaker connections for each zone are
made. First determine which individual wire is ground (negative) and the other being the signal
(positive) of your speaker wire. The detachable speaker connectors are labeled as L- (left negative);
L+ (left positive); R- (right negative); R+ (right positive). There are small set screws on this connector
to allow solderless connections to be made. We suggest using a straight blade Jewelers screwdriver
to easily make this connection.
These speaker outputs are rated at 20 watts RMS a side into an 8 ohm load. Stay within that ohm
rating. This will be more than adequate power for most of the in-wall speakers on the market.
These connectors are then duplicated for the additional five zones and are identical in nature.

4.) Source #1 ight Input ( ed) - This RCA input will accept any standard line level source such
as CD, Receiver, Tuner, DSS, TV audio and more. It connects the right channel.
5.) Source #1 Left Output (White) - This RCA output will send a line level signal out, an e act copy
of that source signal, from the signal plugged into the left channel of source #1 inputs. It is used for
stacking additional KHS6640 units together. This provides an ultra clean audio distribution amplifier
for signal clarity.
6.) Source #1 ight Output ( ed) - This RCA output will send a line level signal out, an e act copy
of that source signal, from the signal plugged into the right channel of source #1 inputs.
These connectors are then duplicated for the additional five sources and are identical in nature.

7.) Master Output - This connector allows the party mode to apply to multiple units if additional
units are added.
8.) Master Input - This is for the party mode controller. This controller should be located near the
unit and sources. It will override all zone controllers and select a source which will then play in all
zones. This mode is used for playing the same background music in all zones such as during a party.
The individual wall controllers still have the ability to select a different source after the party mode is
engaged. It uses a standard 8 pin RJ-45 connector.
9.) Individual Zone #1 Controller - This connector hooks up the wall controllers used in zone #1.
The signals from this wall controller control all the functions in zone #1. It uses a standard 8-pin RJ-
45 connector.
This connector is duplicated for the remaining 5 zones and function e actly the same.
PAGING/VOLTAGE CONT OL SECTION
10.) Audio Inputs - This is an audio sensing circuit and accepts the signal from an e ternal phone
system, or a pre-amplified microphone (i.e.: a mi er output), that has the capability of sending a page
signal from the master phone unit. The signal from this phone system will mute whatever source is
playing in all zones and allow the person speaking to page into all zones simultaneously. When the
signal is disengaged, the music will return to the previous level. Even zones that are not currently
on will open and allow the announcement to be made. Inside the unit is a master DIP type switch
which allow the installer to turn off the paging and doorbell override. This is especially suited for a
nursery. Pin 1 is for signal and pin 2 is for ground.
11.) Switch Inputs - This input is designed for older systems like intercoms that require a push to
talk latch mode contact before the audio signal can pass through. This is a hard bypass of the
audio sources. This can act as a whole house mute as well.
12.) Doorbell A Input - This input takes the signal from the contact closers from the front doorbell
transformer. When engaged, the source signal mutes and a distinctive chime (on board) plays through
the speakers. It will even play through zone speakers that arent on unless locked out.
13.) Doorbell B Input - Same as above but with a separate distinctive chime sound so you can
differentiate between the doors.
14.) Control Voltage Output - This output sends a constant 5 volt D.C. signal out to trigger ancillary
equipment when the unit is powered up. When the unit goes into the sleep mode, this voltage stops.
15.) Control Voltage In - This allows an e ternal sub system that sends a control voltage output to
this system to power up the unit from the sleep mode. This signal can be from 5 to 12 volts D.C.
The front panel power switch must be on for this to work.

# Use Category 5 8-conductor cable. It is not necessary for it to be shielded but be careful with
your cable runs. Avoid running a tight parallel with A.C. wiring. Be careful if stapling the wire to secure
it in place.
# Use high quality RJ-45 connectors and make sure you use a high quality crimp tool. The crimp
of the RJ-45 connectors is crucial in making the system work properly.
# Avoid tight or sharp turns near the ends of the RJ-45 connections to the controller or main
units. This can put e cessive strain on already small wires.
# Note when stacking multiple units: Audio sources connect via the distribution outputs. Wall
controllers combine via the Master Controller Out jack. Make a short jumper and connect to the second
units Master Controller In jack to allow the party mode master controller to access all zones. For
the IR Emitters, we strongly suggest using a Y adapter for the emitters that attach directly from the
sources and then to the second units IR outputs. This allows the source specific functionality to be
utilized by the second KHS6640. An additional controller can be run per zone by using a RJ-45 Y
adapter before the main unit.

KHS6640 INSTALLATION MANUAL

Page 1
KHS6640 Installation Manual
ecommended Cables:
Category-5 or Category-3 (4 twisted pair stranded), shielded or unshielded.
16-4 or (2) 16-2 speaker cables.
To keep the installation process as simple as possible for first time users, please follow these simple steps. These instructions
are written assuming that you are using the KHS6S controller. If you have the KHS6D controller, there are additional steps
involving teaching the controller IR commands.
Please refer to the KHS6640 Reference Manual for additional steps.
Section 1: Installation of Controller Cables and Speaker Cables.
1. Controllers should be located between wall studs. Locating controllers beside light switches is OK as long as the Cat-5
cable and AC wiring (rome ) are not bundled together and in their own bo . Each controller cable is home run between
each zone and the KHS6640 unit.
2. The ends of the Cat-5 cable are terminated with RJ-45 crimp on connectors (unkeyed). The proper wiring is the same
as standard phone company wiring: pin 1 to pin 8, pin 2 to pin 7, pin 3 to pin 6, pin 4 to pin 5,...etc. (see diagram below).
Cable testers are available from your local distributor.
3. Each speaker cable is also home run between each speaker and the KHS6640 unit. One pair of 6-8 ohm speakers per
zone is recommended. The speaker wires are attached to the 4-pin terminal blocks located in the back of the 6640 (these
are easily removable for ease of installation). Please observe proper polarity and left-right orientation.
4. All controllers and speakers can then be hooked up to their proper cables but not to the KHS6640 yet.
Section 2: Installation of the 6640 unit.
1. Place the 6640 in its permanent position in a rack or on a shelf. This unit generates large amounts of heat so please
remember to allow for adequate ventilation. The top clearance must be at least 1 inch (25mm).
2. Attach the AC power cord to the unit and plug the cord into the wall.
At this point the Power switch should be off. The Standby LED should be on but the On LED should be off.
3. Select which device will be source 1 and attach the audio outputs from it to the audio in terminals on the KHS6640 using
standard RCA cables. At this point place this source into play so that you will have audio to monitor.
4. Now attach the speaker connector for zone 1 to the KHS6640 (you decide which room will be which zone, and you should
write these assignments down for future reference).
5. Now press the Power button in to activate the KHS6640 (you should now see both the ON and the STANDBY LEDS
lit on the KHS6640).
6. Now attach the zone 1 controller to the zone 1 controller input on the KHS6640.
7. Now go to zone 1 controller. If the source 1 equipment is playing you should see two LEDs lit on the controller. The red
led that indicates the KHS6640 is powered up and 1 of 6 green LEDs that indicate which source is selected (if the green
LEDs are not lit, try pressing the mute button. This button mutes the source audio in this particular zone). Select the proper
source by pressing the corresponding button on the left of the controller. Press the volume up button to adjust the listening
level.
8. If you do not have sound, please review steps 1-7. If you do have audio please attach the remaining sources to the
KHS6640. If all sources are playing, you should now be able to select whichever source you want to listen to. A more detailed
description of controller operation is in the KHS6S operation manual.
9. Once you are comfortable with the operation of one zone you can proceed with wiring the other zones in the same way.
Section 3: Infrared epeater:
The KHS6640 has a built-in IR repeater system. This works by sensing any IR commands issued by an IR remote in any
zone and passing it through the Cat-5 cable and into the KHS6640 unit. From here it goes to the emitter outputs on the back
of the KHS6640. Any IR emitters plugged into the jacks will flash depending on which source is selected and which jack
that emitter is plugged into. The jacks labeled Source Outputs 1-4 will flash only when that particular source is selected.
The jacks labeled Sum Outputs A-D will flash when any source is selected.
1. Plug an emitter into Source 1 emitter out. Attach the flasher end to the face of the source equipment, making sure to
cover the IR sensor window.
2. You should now be able to select Source 1 on the keypad and, using that sources remote, control that source. Make
sure you point the remote at the rectangular IR window located at the top of the KHS6S.
*SPECIAL NOTE*
IR receivers in consumer electronics operate at different modulation frequencies. The most common is 38khz (kilohertz).
However, some satellite receivers operate at 56khz and some equipment operates at 32khz. Still other equipment is not
even compatible with this type of IR system. The KHS6640 will work with the majority of consumer audio/video equipment.
However, some models will not operate. It is up to the installer to determine compatibility.

Master In/Out:
The master controller input will accept a seventh KHS6S controller. This controller will then become a master control for
the entire system. If Source 1 is selected on this controller, all zones will switch to Source 1.
If volume up is pressed, all zones will go up and visa versa volume down will lower all zones. If mute is pressed, any zones
active will be muted.
The Master Out jack can be connected to the Master In on a second KHS6640 to allow master control of 2 units (12
zones).
Individual rooms then can override this and return to a local zone mode. This way individual zones can be changed to suit
the listener in a particular zone.
Unit On:
When the On LED is lit, there is a +5v DC applied to these pins that can be used to control any equipment such as relays
or digital switches. This voltage is switched off when the Power button is out or the KHS6640 is in the sleep mode such
as with no sources playing.
Trig On:
By applying +5v to +12v DC to these pins, the KHS6640 can be temporarily awakened. If no sources are present, the
KHS6640 will return to the sleep mode when the voltage is removed.
Using Multiple KHS6640 Units:
Up to 3 KHS6640 units may be wired together to provide 18 zones of listening pleasure. First connect all sources into the
first KHS6640 and use the Source Outs to connect to the Source Ins on the second unit. Then use the Source Outs on
the second unit to connect into the Source Ins on the third unit. Ne t, using Y-adapters (2-1/8 plugs to 1- 1/8 jack), connect
all emitter outputs of the KHS6640 to proper source emitters. Lastly, any connections made to page/doorbell status connectors
must also be made to the other KHS6640s.
Adding More Audio Power to the KHS6640:
If you need more audio power in a zone, simply attach an RCA cable in between the Line Out jacks and the inputs of an
e ternal power amplifier. This allows virtually unlimited volumes to be obtained. (Multiple outdoor speakers are a prime
e ample).
Section 4: Special Wiring Schemes:
The following connections are made to the KHS6640 via the 12 pin terminal block located on the back of the unit. Cat-5
wire or doorbell wire is perfectly suitable for all of these connections.
1. Page/ Doorbell Status:
Paging: The 6640 has two ways to allow e ternal paging to be amplified through it. The jacks labeled Audio Input will
accept any audio signal and will mute the sources and play the page audio automatically. The page sensitivity and level
are adjustable via trim pots located inside the KHS6640 (see fig. 1, page 3). Additionally, there are two pins labeled Mute
Input. When a DC voltage (+5v to +12v) is applied to these pins the source audio will mute and remain muted until the
voltage is dropped. Using an e ternal voltage for the page mute function will still allow an audio page to be amplified through
the system and may be advantageous when dealing with a noisy phone line (See diagram page 4).
Doorbell: The KHS6640 has two built-in and distinctly different doorbell sounds (ding and ding dong). Either doorbell can
be triggered by attaching wires from the houses doorbell transformer (switch side) to the terminals on the KHS6640 labeled
Doorbell A or B. Any voltage from 5v to 24v AC or DC will trigger the doorbell. This allows this feature to be used with
most types of e isting doorbells. Doorbell volume can be adjusted via a trim pot located inside the KHS6640 (see fig. 2,
page 3). The paging and doorbell features can be further customized in each zone. You can disable the page/doorbell
feature in a zone by setting both slide switches on that zone board to Off. This might be of use in a nursery, for instance.
You can set a zone to only mute the sources, but not play the page or doorbell by setting Switch to On, but setting audio
to Off. Finally, you could set Switch to Off and set Audio to On. This would allow the page or doorbell audio to mi
with the source audio (see fig. 3, page 3).
Telephone Entry Systems:
The KHS6640 is well suited to be integrated into a telephone entry system. With these systems you can page from any
phone in the house through the KHS6640 system. You can also trigger the doorbell or mute the system in some or all zones.
Please consult their owners manuals for operation. In the case of the Panasonic phone entry system using the KX-T30865
Doorphone, you must use the KHSPDA-1 to supply the necessary voltage to cause the 6640s internal doorbell to chime.
(See Pages 4 and 5 for the wiring diagrams of the most popular models.)

The KHS6D controller is designed to learn and store IR codes for virtually any piece of audio/video
equipment. This enables the individual programming and use of multiple functions for all of your source
components.
Programming Individual Functions
1) Press the learn button on the controller. The left, red Clone/Learn LED will begin flashing.
2) Press the source device button to be programmed.
3) Press the numeric or function key you wish to program on the right side of the controller. The red
Clone/Learn LED will stop flashing and glow continuously.
4) Hold the source remote control IR emitter 1 to 2 from the IR Sensor on the controller and press
the corresponding function key on the source remote. After a short period of time, the right, green OK
LED will glow indicating the acceptance of that command. At this point the controller will return to a
flashing red LED. It is now ready to be taught the ne t command for that source. (A solid red and green
LED simultaneously indicates an error with that command. Should this occur, clear it and try reentering
that function.)
5) Repeat steps 2-4 for the ne t desired function.
6) When all the desired functions for a particular source have been programmed, we suggest you reset
the keypad.
7) Repeat steps 1-6 for the remaining functions.
(All of the numeric and function keys will learn any ir code. Functions programmed into the controller
are solely at the discretion of the installer.)
Cloning
The has a cloning feature that will allow you to down load the information stored in one controller to
up to five additional controllers within an installation.
Once one of the controllers is programmed, go to the other controllers and press the Clone RX button.
Then return to the programmed controller and press the Clone/TX button. The green LED will remain
lit while the cloning process is in progress. When the process is complete, the green LED will turn off.
This should take about 8 minutes. It is a good idea to then reset all of the controllers.
Now all the controllers share identical information. The nonvolatile memory will remain regardless of
whether the controllers are plugged into the system. Using the Clear button will clear the controller
memory. To erase an entire page of memory, simply press the Clear button and then a Source Device
button. By pressing a source device button, the Clear button and one of the programmed function
buttons will erase a single function. Once cleared, a controller or individual function can be reprogrammed.
NOTE:
It is important to avoid issuing any IR commands or allowing any e ternal IR interference during the
cloning process. This will result in corrupted information being sent to the receiving controllers.
Should a controllers programming be corrupted, it may be necessary to completely clear a controller
to factory condition. This is done by cloning an unprogrammed controller to the corrupted controller.
Once this is done, that controller can then be re-cloned.

The KHS6D has 16 programmable macro memories. It will automatically transmit a series of 20
commands deep.
To enter the macro mode - press macro and the either the 0 through 9 buttons OR the device source
keys (1-6). You can insert a delay time from 1 to 99 seconds between steps (the default is .5 sec.) to
suit their specialized needs. To program in time delays, press the appropriate button and hold it from
1 to 99 seconds then input the ne t command.
Here is an e ample of how to set a macro.
The list of things you want to accomplish are:
1.) Power on CD1
2.) Put CD player in disc change mode.
3.) Select disc 10.
4.) Select play mode for CD player.
Press Learn then the M button to enter the macro learning mode. The Red LED should begin flashing.
Then press the CD1 source device button on the left side of the controller. The following functions will
then be grouped as a macro under the CD1 source button.
The following selections are made on the right side of the KHS6D dual controller. See diagram page
7.
1.) Press PWR button
2.) Press the button programmed for disc select
3.) Enter 1 and 0 on the numeric keypad
4.) Press the button programmed for disc enter
5.) Press the button programmed for play
Press the learn button or wait 15 seconds for it to return to normal. The red LED should turn off.
To utilize the macro mode, press the M button (it will only wait for 2 seconds for a second button to
be pressed) then press either numeric button (0-9) or source button (1-6) to engage a pre-programmed
macro.
To clear a macro out of memory, press the CLEAR then the M buttons and then the key with the
memory you wish to erase. It is a permanent erase, so make sure you are careful. If no key is pressed
within 15 seconds, the unit will e it the clear mode and return to normal operation.
NOTE: All macro commands must come from individual commands already programmed in the KHS6D.
They cannot come from the sources wireless remote.

P OG AMMING A WI ELESS EMOTE
USING THE KHS6S O KHS6D WALL CONT OLLE

Can I control volume and source selection with a wireless remote?
Yes, the KHS6S and the KHS6D controllers have a built-in IR emitter that will teach learning remote
the Kustom IR codes for volume, source selection, and mute.
How do I control I if I am using more than one 6640 amplifier?
The best solution is to use Y cords with two 1/8 male ends going to a 1/8 female end. This works
with the 4 source outputs as well as the 4 summed outputs.
Can I use more than one controller within a single zone?
Yes, the controllers can be tied together via a cat. 5 Y cord or an RJ45-Y adapter. We suggest using
only two controllers within one zone. It is also possible to control two zones with one controller.
Can I use more than one pair of speakers within a single zone?
The 6640 is intended to be used with two 8 ohm speakers per zone. It is equipped with line level preamp
outs for each zone. You can line out to any e ternal amplifier using standard RCA cables. This makes
it possible to power additional speakers, or a powered subwoofer for surround sound systems.
Do I have to have all zones playing music to be able to hear the doorbell and page?
No, the page and doorbell features will work regardless of the status of the zones. You can, however,
use internal switches on each zone to defeat the doorbell and page, or allow the doorbell and page
without muting the system.
Can I program functions into a macro other than my audio equipment?
The 6D controller will learn and store any IR code in its memory. Once an IR command is programmed,
that can then be used as part of a series of macro commands. It is important to note that the 6D can
only do macros on commands that have already been stored into the controller's memory.
Do I need to have a backup for the memory in case of a power outage?
No, the 6D controller has a non-volatile memory that will retain its memory once the controller has been
programmed.
How do I utilize the doorbell and page features?
The doorbell and page can be wired with simple two-conductor doorbell wire or standard twisted pair
wire such as Cat. 5 or Cat. 3. The doorbell can be lined off of the e isting doorbell transformer, or from
the doorbell strike on the phone system. Since this feature utilizes a voltage to trigger an internal
closure, a 9-volt battery will trigger the doorbell chimes. The page function can be used in two different
ways. The simplest method is to take the audio line out from your phone system directly to the audio
in on the 6640. The 6640 is designed to sense the incoming signal and mute the system until a signal
is no longer present, at which point it will return to normal operation. It may be necessary to adjust the
sensitivity on the page/doorbell board of the 6640 to compensate for additional noise in the phone line.
An alternative solution to eliminate sensitivity problems between the 6640 and the phone system is to
add a second power supply (this can be a typical "wall wart") to one of the contact relays on the phone
system and from there to the mute input on the 6640. This will mute the system regardless of an
incoming audio signal, and will remain muted until the phone is hung up.
What if none of the lights on the controller come on?
It could be that the POWER button is not depressed on the KHS6640. Ne t verify that you have a
source plugged in and playing. Remember that the 6640 will go into standby mode after appro imately
2 minutes if no incoming signal is detected. If both of these conditions have been met then you probably
have an incorrectly wired Cat-5 cable. The correct pin assignment from end to end is: 1 to 8, 2 to 7,
3 to 6, 4 to 5, 5 to 4, 6 to 3, 7 to 2, and 8 to 1.
What does it mean if the red power LED is lit on the controller, but none of the source LEDs
is lit?
This condition indicates that the controller is muted. Press the mute button to turn off the mute in
that zone at which point one of the source LEDs should light. If this doesnt solve the problem, and
