SIX-ZONE AMPLIFICATION SYSTEM
MODEL KHS6640
A.) Power Switch - Left on, the KHS6640, when not being used, will go into a “sleep” mode, ready
to turn back on when an input signal is applied from any of the six sources. In the off position, the unit
will not function.
B.) On LED - with the power switch on, this LED indicates that the unit is powered up and “awake”.
C.)
Standby LED - this LED indicates that the unit is plugged into the wall and is in the “sleep” mode.
It remains on as long as the unit is plugged into the wall.
D.) Output Section - this section is the output section. It provides the speaker terminals and line
outputs.
E.) Distribution Section - this section is the line level input/output section. It provides the inputs from
your sources and the outputs for stacking additional units.
F.) Controller Section - this section is where the wall controller in each zone connect. This section
includes the “party” mode master controller input.
G.) Paging/Control Voltage Section - this section is the Paging and Control Voltage Input and output
section. It provides the inputs from your phone system, door bells (front and back). It also has a control
voltage input and output for the unit controlling or being controlled by additional equipment.
H.) Infrared (IR) Section - this is the IR section. It provides outputs for the IR emitters.
I.)
AC Power Cord -this
is where the AC power cord connects to the unit. It is a detachable 3 prong
I.E.C. plug.

OUTPUT SECTION

1.) Line Outputs (Left & Right) - 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 and hook those speakers up and
you are set to go.
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 above explanation.
2.)
Speaker Connectors -these
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.
DISTRIBUTION SECTION
3.)
Source #I Left Input (White) - this RCA input will accept any standard line level source such
as CD, Receiver, Tuner, DSS, TV audio and more. It connects the left channel.
4.) Source #I Right Input (Red) - 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 #I Left Output (White) - this RCA output will send a line level signal out, an exact copy
of that source signal, from the signal plugged into the left channel of source
stacking additional KHS6640 units together. This provides an ultra clean audio distribution amplifier
for signal clarity.

7.) Master IR Output
-
this connector allows the “party” mode to apply to multiple units if additional
units are added.
8.) Master IR 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.

10.) Audio Inputs
this is an audio sensing circuit and accepts the signal from an external phone
system or a pre-amplified microphone (i.e.: a mixer 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 and make
their announcement. 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.) Front Doorbell 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.)
Back Doorbell Input
-
same as above but with a separate distinctive chime sound so you can
differentiate between the doors.
14.) Control Voltage In
-
this allows an external 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.
15.) 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.

2 conductor jack is from the
IR
emitters and are “locked” source
specific. This is useful in the instance, if you have 2 or more of the same brand CD player, since the
same IR command will work on both, this ONLY sends the IR command to this particular source.
Nearly any brand of emitter will work. There are four source specific IR jacks.
This connector is duplicated for the remaining 3 zones and function exactly the same as the first one.

INSTALLATION NOTES
WIRING DIAGRAM FOR REMOTE ROOM CONTROLLERS
l
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.
l
Use high quality RJ-45 connectors and make sure you use a high quality crimp tool. The
connection of the RJ-45 connectors is crucial in making the system work properly.
l
Avoid tight or sharp turns near the ends of the RJ-45 connections to the controller or main
units. This can put excessive strain on already small wires.
l
Note when stacking multiple units: Audio sources connect via the distribution outputs and 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 then allows the source specific functionality
to be utilized by the second KHS-6640. An additional controller can be run per zone by using a
45
“Y”
adapter before the main unit.
