KHS 6640 Installation Manual
Recommended Cables:
Category-5 or Category-3
(4
twisted pair stranded), shielded or unshielded.
164
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
KHSGS
controller. If you have the
KHSGD
controller. There are additional steps
involving teaching the controller ir commands.
Please refer to the KHS-6640 Reference Manual for additional steps.
Section 1: Installation of Controller Cables and Speaker Cables.
1. Controllers should be located between wall studs and at the same height as light switches. Locating controllers beside light
switches is o.k. as long as the Cat-5 cable and AC wiring (romex) are not bundled together and in their own box. Each controller
cable is “home run” between each zone and the KHS-6640 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
S,...etc.
(see
fig.1).
Cable testers are
available from your local distributor.
3. Each speaker cable is also “home run” between each speaker and the KHS-6640 unit. One pair of 6-8 ohm speakers per zone
is recommended. The speaker wires are attached to the green 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 KHS-6640 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.
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 be off.
3. Select which device will be source 1 and attach the audio outputs from it to the audio in terminals on the KHS-6640. 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 KHS-6640 (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 KHS-6640 (you should now see both the “ON” and the “STANDBY” LED’S lit
on the KHS-6640.
6. Now attach the zone 1 controller to the zone 1 controller input on the KHS-6640.
7. Now go to zone 1 controller. If the source 1 equipment is pla
that indicates the KHS-6640 is powered up and 1 of 6 green L
2
ing you should see two LED’s lit on the controller. The red led
D’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 l-7. If you do have audio please attach the remaining sources to the KHS-6640.
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
KHSGS
operation manual.
9. Once you are comfortable with the operation of one zone you can proceed to wire the other zones in the same way.
Section 3: Infrared Repeater:
The KHS-6640 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
KHS-6640
unit. From here it goes to the emitter outputs on the back of the
KHS-6640. Any IR emitters plugged into the jacks will flash depending which source is selected and which jack that emitter is
plugged into. The jacks labeled “Source Outputs
l-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 KHSGS.
*SPECIAL NOTE*
IR receivers in consumer electronics operate at different modulation frequencies. The most common is 38khz (kilohertz). However,
most 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 KHS-6640 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.
