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. 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
explanation.
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.

3.) Source #1 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 #1 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 #1 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 #1 inputs. It is used for
stacking additional MDS-6 units together. This provides an ultra clean audio distribution amplifier for
signal clarity.
6.) Source #1 Right Output (Red) - This RCA output will send a line level signal out, an exact 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 exactly the same.

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. 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 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.

16.) Source Output #1 through 4 - This 1/8” 2 conductor jack is for the IR emitters and are “locked”
source specific. This is useful in for 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 outputs and function exactly the same as the first
one.
17.) Sum Output #1 through 4 - This 1/8” 2 conductor jack is for the IR emitters and are summed
across the IR buss. This will allow normal operation of different components that don’t share the same
IR commands. There are four sum output IR jacks.
This connector is duplicated for the remaining 3 outputs and function exactly the same as the first
one..

INSTALLATION NOTES
TO MCS-1 or MCS-2
WIRING DIAGRAM FOR REMOTE ROOM CONTROLLERS
# 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 AC 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 excessive 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 MDS-6. An additional controller can be run per zone by using a RJ-45 “Y”
adapter before the main unit.

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 (romex) are not bundled together and in their own box. Each controller cable is “home run” between each zone
and the MDS-6 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 d i a g r a m b e l o w ). Cable
testers are available from your local distributor.
3. Each speaker cable is also “home run” between each speaker and the MDS-6 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 MDS-6 (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 MDS-6 yet.

WIRING DIAGRAM FOR REMOTE ROOM CONTROLLERS
Section 2: Installation of the MDS-6 unit.
1. Place the MDS-6 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 MDS-6 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 MDS-6 (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 MDS-6 (you should now see both the “ON” and the “STANDBY” LED’S lit
on the MDS-6).
6. Now attach the zone 1 controller to the zone 1 controller input on the MDS-6.
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 MDS-6 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 MDS-6.
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 MCS-1 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 Repeater:
The MDS-6 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 MDS-6 unit. From here it goes to the emitter outputs on the back of the
MDS-6. 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 MCS-1.
*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 MDS-6 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.
Page 1
Master In/Out:
The master controller input will accept a seventh MCS-1 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 MDS-6 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 MDS-6 is in the “sleep” mode such as with
no sources playing.
Trig On:
By applying +5v to +12v DC to these pins, the MDS-6 can be temporarily “awakened”. If no sources are present, the MDS-6
will return to the “sleep” mode when the voltage is removed.
Using Multiple MDS-6 Units:
Up to 3 MDS-6 units may be wired together to provide 18 zones of listening pleasure. First connect all sources into the first
MDS-6 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. Next, using Y-adapters (2-1/8” plugs to 1- 1/8” jack), connect all emitter
outputs of the MDS-6 to proper source emitters. Lastly, any connections made to page/doorbell status connectors must also
be made to the other MDS-6’s.
Adding More Audio Power to the MDS-6:
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 external
power amplifier. This allows virtually unlimited volumes to be obtained. (Multiple outdoor speakers are a prime example).
Section 4: Special Wiring Schemes:
The following connections are made to the MDS-6 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 MDS-6 has two ways to allow external 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 MDS-6 (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 external 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 MDS-6 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 MDS-6 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
existing doorbells. Doorbell volume can be adjusted via a trim pot located inside the MDS-6 (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 mix with the source audio (see fig. 3, page 3).
Telephone Entry Systems:
The MDS-6 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 MDS-6 system. You can also trigger the doorbell or mute the system in some or all zones. Please consult
their owner’s manuals for operation (See Page 4 for the wiring diagrams of the ChannelPlus Door Tel.).

PROGRAMMING THE MCS-2 CONTROLLERS
The MCS-2 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 next 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 next 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 MCS-2 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 external 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.
Page 8
MACRO PROGRAMMING
The MCS-2 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 next command.
Here is an example 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 MCS-2 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 exit the clear mode and return to normal operation.
NOTE: All macro commands must come from individual commands already programmed in the MCS-2.
They cannot come from the sources wireless remote.

PROGRAMMING A WIRELESS REMOTE
USING THE MCS-1 OR MCS-2 WALL CONTROLLER
1) Remove the Decora cover plate, and controller face plate.
2) Place your wireless remote in learn mode.
3) Select the device bank button to program (i.e. TV, VCR, Tuner, Aux, etc.) on the wireless remote.
4) Select the button to be programmed on the learning remote. (i.e. 1-6, mute, or volume up and down)
5) While holding the wireless remote within 2" from the top, center, clear LED on the MCS-1 (this is the
controller IR emitter), press the command button on the MCS-1 Controller you wish to program into the
wireless remote.
6) The wireless remote should then accept the MCS-1 command.
7) Once you have programmed the source number, volume up and down, and mute functions. You
can then go to the memory bank on your wireless remote chosen for the MDS-6 system to change
volume, source, or mute the system from any zone in the house.
*Please Note:
When programming, it is best to hold the MCS-1 or MCS-2 button until the wireless remote has indicated
that it has learned the command.
Page 10
Standard Installation Questions for the MDS-6
Can I control volume and source selection with a wireless remote?
Yes, the MCS-1 and the MCS-2 controllers have a built-in IR emitter that will teach learning remote the
ChannelPlus IR codes for volume, source selection, and mute.
How do I control IR if I am using more than one MDS-6 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 MDS-6 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 external 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 MCS-2 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 MCS-2 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 MCS-2 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 existing 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 MDS-6. The MDS-6 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 MDS-6 to compensate for additional noise in
the phone line. An alternative solution to eliminate sensitivity problems between the MDS-6 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 MDS-6. 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 MDS-6. Next verify that you have a source
plugged in and playing. Remember that the MDS-6 will go into standby mode after approximately 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.
Page 11
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
you are using the paging and or doorbell hook-ups on the back of the MDS-6, disconnect these. If the
page audio inputs are causing the muting then try adjusting the page sensitivity pot in the inside of the
MDS-6 (see the owners manual). Sometimes it is necessary to “reset” the MCS-2 controller by pressing
the “reset” button on the controller.
When I am installing the MCS-2 controller, do I have to program each one individually?
No. The MCS-2 are equipped with a unique cloning feature. Once you have programmed one controller,
you then go to the other controllers in the house and press the “Clone RX” button. Then go back to
the programmed controller and press the “clone TX” button. The process then occurs automatically,
but you need to make sure that you are pressing the “clone TX” button before the others have timed
out, or reverted back to normal operation. In a large house, it may be necessary to do smaller groups
of controllers at one time. Future runs of the controllers will have an increased time out of 15 minutes.
Once I have programmed my MCS-2 controller, why does some of the source equipment not
work?
It is possible that the MCS-2 did not store all the commands properly. Try repeating IR commands with
the source remote through the IR window of the controller. If the commands pass through the system,
then go back to the controller and reenter the desired functions. If the source remote does not work
through the systems IR repeater, then you could have a defective emitter. If a different emitter does
not solve the problem, then possibly the modulation frequency of the source’s IR is well above 40kHz
or well below 40kHz. Either scenario is fixable by adjusting the IR frequency trim pot (see the owner’s
manual p.9).
I am not using the page or doorbell functions of the MDS-6, but my system has a tendency to
mute.
The MDS-6 amplifier is equipped with a sensitivity adjustment for the page mute function. It is located
on the page /doorbell board inside the unit (see the owner’s manual p. 9). This trim pot could be set
sensitive enough that external noise is triggering the audio sensing circuit. This can be remedied by
turning the sensitivity pot completely counter clockwise. An external solution is to place a short wire
jumper across the “Audio input” signal and ground on the 12 pin input located on the back of the unit,
thereby disabling the audio sensing circuit of the MDS-6 amplifier.
