Delta Installation - Quick Start Steps
1. Connect the Source Units to Delta
Plug RCA audio cables from each source device into the labeled RCA jacks at the back of the Delta
Controller. Ensure that right and left are connected correctly. Then connect the IR emitter leads for each
audio source into the appropriate connector on the back of the Delta Controller and run the optical end of
the emitter lead to the source device’s IR receiver window.
Attach the emitter by peeling and sticking the supplied adhesive patch on the emitter. If an on-board
tuner is pre-installed into Delta, you must also connect AM and FM antennas as shown in FIG. 1.

Although speaker wire is commonly used, you can also use CAT-5 or other paired wiring.
Please see the complete Delta Installation Manual for details.
3. Connect the Speakers to the Keypads
Speakers will be wired according to their positive and negative terminals, which are usually Red and
Black for each speaker. Once installed in their locations, the speaker wiring is typically run to the keypad
location and is connected into the connector on the left side of the keypad. Repeat this for each zone in
the system (up to six). There are alternative connection schemes for speakers directly to Delta or via
external amplifier.

Delta Installation - Quick Start Steps
4. Power Up and Test the Basic System Operation
Make sure the Delta Controller is plugged into the wall and the power switch on the back panel is in the
ON position. The Delta system should now be ready for initial testing.
To test the system connections, activate one source from a keypad. Begin by manually activating one of
the available audio sources such as the tuner and move through each zone and test that keypads respond
to the on/off, volume, and tone control commands and that the source can be heard in all zones on both
speakers.
We assume the programming has not yet taken place
The basic functionality of the Delta Controller (which means turning Delta on/off, volume up/down and
treble/bass/balance) are functions that can be performed without programming (FIG. 4).
Press any Source Key
for "ON"
FIG. 4 Power Up and Test the Basic System Operation
Use Keypad to adjust
Bass and Balance to begin settings
Press Vol+ and Vol -
If a tuner module has been installed, all of the basic tuner operations will also be able to function without
any programming so you will have sound for a test signal right away. The IR repeaters must be installed
and basic source component commands must be programmed to select and/or control any external
sources however. Until then, you will have to manually turn on and start the external source component if
used as a test source!
Turning a Zone ON
Pressing the Source key turns the system on in the room you are in and also turns that source on if it has
not been previously selected in another zone. The indicator next to the source will light Red. Through
Matrix’s own Dynamic Macro process, sources that are muted or paused will be turned off after they are
idle (not selected in any zone) for ten minutes. Press the active source button again to turn the zone off.
Volume Control
Control of the system volume is very intuitive because of discrete buttons for the Volume UP and
Volume DOWN command. When increasing or decreasing volume, the progression is in 3dB steps when
the volume is half (of maximum) or below. Above the halfway point, the progression drops to 1dB steps
so you can fine tune the adjustment without worry of overdriving speakers by surprise.
Delta Series Quick Start Guide

Delta Installation - Quick Start Steps
Tone Control
The tone control mode allows the user to adjust Bass, Treble, and Balance on a “per zone” basis. To enter
tone control mode, press VOL UP & VOL DOWN buttons simultaneously until LED’s begin to cycle in
a counter-clockwise motion.
This will enable the BASS and BALANCE settings first. At any time during adjustments, If you want to
return the settings to default, press and hold the centre keypad navigation button. When you are satisfied
with your adjustment, press (but not hold) the centre keypad navigation button to save the bass and
balance adjustment. This will take you to the treble and balance adjustment mode. Once again, once
adjustments are complete, press (but not hold) the centre keypad navigation button to return to normal
operation mode.
5. Basic Programming
The key to successful programming is to understand how each of the source components operates.
Programming and IR Capture take place on the front panel of the Delta Controller. Settings such as Bass,
Treble, and Balance functions are programmed from within any zone using the keypad. We suggest you
read this section carefully in its entirety BEFORE starting to program the Delta Controller. This will
allow you to obtain a general understanding of what you will see and what to expect when you go
through the programming exercise.
IR Learning Techniques
Programming techniques may need to be modified on a remote-by-remote basis. Some remotes may
need to be closer to or further away from the Delta Controller. Some may program better with quick key
presses and some with long key presses. Generally speaking, the audio source remote should be located
about 6-12 inches away from the IR receiver on the Delta Controller.
The path between the devices should be unobstructed with a clear line of sight.
Fluorescent light fixtures and bright sunlight may interfere with the learning process, so you may choose
to shade the IR receiver with a sheet of paper or other practical means. When possible use only
incandescent lighting during the programming session. During programming, distance between the
remote and the Delta Controller is also important. If the remote is too close to the unit the IR signal will
overload the learner. If it’s to far away, it might not learn due to weak signals strength. A bit of trial and
error will quickly get you to the correct distance.
Program Panel
The programming controls (also called the “navigational array”) and the IR receiver are located on the
front of the Delta Controller. The four directional buttons allow you to navigate through the menu
screens. The centre button is used to make selections (as if to press OK or ENTER).
Refer to the Programming the Delta System section on page 27 for detailed programming instructions.

Pre-Installation Precautions and Recommendations
The Matrix Delta system is extremely flexible. It can be installed in a number of configurations
depending on your audio needs. The capacity of a single unit is 6 independent zones and is typically
wired with at least one keypad located in each zone. In some cases it is desirable to operate a second set
of speakers within the same zone controlled by the same keypad. The Delta Controller will power 2 sets
of speakers as long as the impedance does not drop below 4 ohms. If you have two common zones such
as the Master Bedroom and Master Bathroom you can use the a single keypad and multiple analog
volume controls for independent control of the two areas while sharing the same source control
capability. Up to 2 Matrix keypads can also be connected in a zone as a with a single pair of speakers.
Each zone can be configured with either 2 pushbutton keypads (Numeric or Source),
or 1 LCD Keypad and 1 pushbutton Keypad, but not 2 LCD keypads.
See the Multiple Keypads in a Zone section on page 26 for details.
Note to Professional Installers
Wiring and Connections
AMX always recommends professional installation for our products. As with any entertainment product
in a home or commercial application, a Delta system installation will go much faster and more smoothly
if job plans are completed prior to the actual installation.
Accurate record keeping will assist not only in the installation, but also in training the client in the
operation of the system. This will also be a great tool for any future servicing issues that may arise.
We recommend that you make copies of the records and leave them behind with your client as well as
putting a duplicate copy in your client’s file. For the professional installer’s convenience, programming
worksheets are available at www.amx.com.
Installing Source Equipment
To meet airflow and cooling requirements, place each audio source on an individual shelf and allow a
minimum of 3” clearance on the sides and top of the unit. Stacking equipment is not recommended as
this presents situations in which airflow is restricted or component cooling may be impaired. The audio
source equipment and the Controller will generate small amounts of heat that must be dissipated to
extend component life and maintain performance.
Equipment should have adequate room in the rear for the cables to reside. If rear access, or a rack a
mounted structure has been provided then cable installation will be much easier.
Cabling Installation Instructions
Please be sure to check for any wiring restrictions required by the electrical code in your area.
This installation uses low voltage cabling similar to telephone and alarm wiring, and as such does not
commonly have very many restrictions on their installation. However rules may vary in different regions.
Please check with your local code enforcement official to determine if any specific conditions must be
met to comply with local electrical codes.
Delta Series Audio Controllers

Wiring and Connections
Cable Type
The Delta Controller is cabled using standard 4-conductor speaker cable originating at the Delta control
unit passing through the keypad and terminating at the speaker location. Matrix Audio Designs generally
recommends using a bundled 4 conductor 16 gauge stranded copper wire in a single continuous run. The
keypads also function with Cat 5 or basically any 2 conductor wire configuration that is not used for
other devices.
RF Interference
Shielded cable is generally not required for audio installations. Although the Delta Controller does
generate very low radio frequency emissions, it uses a digital signaling path during command entry.
There are normally no ongoing data communications in the circuit path. Communications only occur at
the time a command is issued from a zone. However many other systems do use microprocessor systems
where the cabling may be in close proximity such as telephone and security systems, and it is possible
for different systems to interfere with each other. If you face an installation where your cable runs are in
parallel to these types of systems you may consider shielded cable to the keypads. In this case ground the
drain wire by connecting it to the chassis of the Delta Controller.
Distribution Wiring
In general, wiring is installed in a single continuous run between the Delta Controller, the keypad and the
speaker location. Other cable routing options such as a home run to a common wiring distribution point,
integration with home automation systems, or split zone applications can be significantly different than
the general information presented here. These applications are left to the installer’s discretion and
experience, which is why Matrix Audio recommends installation by a professional. Examples of
common wiring options can be found in the “Controller Connections” section of this manual.
Considerations for New Construction Installations
It’s generally accepted to run the 2 and 4 conductor speaker cables inside walls, in the attic and between
the joists in the basement or crawl space. When installing cables within walls, drill the holes in the
middle of the studs to avoid having them damaged by screws or nails that could penetrate the cable. Use
metal nail guard plates where necessary to protect the cable from future construction damage or from
something like nails/screws that are installed to hang future pictures or shelving. When running cables in
the attic or crawl space, run them in such a way that they will be out of harm, where they will not be
stepped on, snagged, punctured, or could pose a safety hazard.
Do not run cable thru the return air path that utilizes the wall or ceiling space as the plenum.
Securing the Cables
We recommend using electrical cable straps to keep the installation neat and secure. We do not
recommend stapling the cables as a single misplaced staple can cause a short that causes trouble during
operations and set-up. Do not leave the wires lying in the dirt under the crawl space.
Neatness counts in a professional installation.
Keypad “Rough In” Locations
The keypad device itself will fit in a standard electrical box or new construction plate and you should
install 1 or 2 gang (as required) standard electrical boxes to accommodate them before the drywall has
been put into place. Keep in mind that because these are low voltage applications, plastic electrical boxes
are generally adequate for the keypad, but check local building code requirements to be sure. The high
voltage electricians on the job site will know which electrical box is appropriate and within code.These
emissions have been accommodated for in design and conform to RF emission standards.

Delta Series Audio Controllers
Wiring and Connections
Considerations for Existing Construction
For existing construction, successful implementation can be achieved by using retrofit electrical boxes
that do not require stud mounting or metal electrical frames which are commonly used for telephone and
cable installations. These “afterthought” low voltage electrical boxes can be placed in a standard opening
in the wall. Care must be taken when using these frames that they must not come in contact with the back
of the unit, or provide a shorting path at the cable connections.
When installing near other switches, make sure the boxes are dead level and lined up with existing
electrical boxes.
Running Wires in Existing Construction
A neat and careful installation in an existing construction application will increase the customer
satisfaction level as well as reduce the chance of service calls in the future. Run cables inside the walls
(wherever possible) to the attic, basement, or crawl space. Some installers cut the long straight section
from a coat hanger and chuck it into a drill to help establish a reference marker through ceilings and
floors up against the edge of a wall. The coat hanger wire is tough enough to drill through most materials
without snagging the carpet fibers. The wire is fairly unobtrusive and the length makes it easy to spot on
the other side. The small hole left behind is usually hidden by the carpet, or easily repaired. Holes in the
stud wall for the wiring can then be made by taking into account the width of the baseboard, drywall, and
half the stud (usually 1/2” + 1/2” + 1- 1/ 2 or 2- 1/ 2” from the pilot hole.)
If you must run wires in a room that is carpeted, you can carefully place the cables under the baseboard
or you can lift the edge of the carpet and place the wiring between the carpet’s tack strip and the wall. Be
careful going past doorways or across a walking path. A cable doesn’t seem too big until it’s tripped over
or causes an unsightly lump in the carpet, so please consider cable diameter where necessary. In some
cases when running wire under carpet or a threshold, you may discover that multiple 2 conductor speaker
wiring will sit flatter than a single bundled 4 conductor wire.
Marking the Cables
When running each cable, carry a fine tip permanent marker with you and mark both ends of the cable.
When you get to the keypad location, mark a couple of arrows on the cable to show you in which
direction the speakers are and in which direction the Delta Controller is. This will save you time,
eliminating the need to “Ohm-out” the cables later to find the one you’re looking for. A few additional
seconds spent during the wiring stage will save you hours of cable chasing later.
Existing Electrical Boxes for Keypads
Due to the varying manufactured sizes of electrical plates and boxes carefully mark a level and plumb
outline of the switch box using the box itself as a template and make a hole in the existing wall with a
drywall or reciprocating saw. Please be careful to ensure that the space you’re cutting into does not hide
any plumbing, electrical or heating fixtures that could be damaged or cause personal injury. Care must
also be taken when dealing with outside walls. The vapor barrier should be repaired if damaged.

Considerations for Outdoor Zones
Outdoor listening zone locations present some unique challenges, both for the wiring and for the control
keypad placement.
Outdoor Wiring
Special care should be taken when cables transit outside the structure. External cabling should run
through conduit (plastic electrical conduit works well) to protect it from the elements and small animals
that may wish to chew on the cable.You may wish to consider a qualified electrical contractor to install
electrical conduit for external applications. Cable and installation accessories to complete your
installation are not part of the system package but can be obtained at your local electrical supply house,
national home improvement centres, and even at most neighborhood hardware stores. These places may
also have a selection of cable that’s geared just for specific outdoor applications (such as “buried”
speaker cables).
Outdoor Keypads
Choosing the location of the keypad control device is perhaps the most important decision. It is not
recommended that keypads be installed in environments subject to extreme temperatures, or moisture.
Typically keypads are installed inside the home and beside the door adjacent to the outside music zone,
but this may not always be possible or practical.
Keypads that must be installed outside are installed at your own risk and should be installed in
weatherproof electrical boxes.
Keypads used outdoors should be safely mounted inside a weatherproof electrical box with a door
covering the keypad and adequate water barrier seals to protect the unit. Once again, the appropriate
weather proof enclosures can be obtained at your local electrical supply house, national home
improvement centres, and even at most neighborhood hardware stores. Be sure to check what is available
and plan your installation before doing the work with an outdoor zone because the materials you have (or
do not) have available could easily influence the choices you make to execute the installation.
Keypads installed outside must be inside a weatherproof box with a cover that seals
out moisture. Keypads returned to AMX for repair that are found to be corroded will
not be covered under the AMX Warranty.
Controller Connections
Source Unit to Controller Connections
Plug RCA audio cables from each source device into the RCA jacks provided on the back of the Delta
Controller. Ensure that right and left are connected correctly. The balance will be backward on that
source and the audio will not image properly if right and left are reversed. Then connect the IR emitter
leads for each audio source into the appropriate connector on the back of the Delta Controller and run the
optical end of the emitter lead to the source device’s IR receiver window.
Attach the emitter by peeling and sticking the supplied adhesive patch on the emitter.
Plug in the IR Emitters to the appropriate source number.
Strip and attach wiring to keypads on the appropriate zone output.

docking station with IR control and RCA outputs.

FIG. 5 Source Unit to Controller Connections
Source Input #1 is left open because the default is the internal AM/FM tuner.
The Delta Controller learns the IR commands for power on/off during the programming setup. Source
components are turned on when they are selected on the keypad. The source remains on until it has been
idle in all zones for a duration of 10 minutes, then Delta will automatically turn it off until it is selected
again.
Make sure that the IR emitter output is plugged into the same numbered IR port as
the source component input RCA jacks.
AM/FM Tuner Connections
The internal AM/FM tuner does not require any special programming or setup other than presets.
1. Connect a 75 Ohm adaptor and antenna to the FM coaxial plug.
2. Connect the two leads of an AM loop antenna to the AM spring clips.
3. Position both antennas as high as possible to allow for optimal station reception.

Wiring and Connections
Depending on the installation location, it may be necessary to use a powered FM
antenna to receive clear FM stations.
When an AM/FM tuner has been installed, input #1 will default to the internal tuner and the RCA input
jacks will not be active for source #1. If no internal tuner is installed, the source #1 inputs will be active.
Either way, Source#1 is activated by the top-left button on the keypads.
See “Using the Matrix Keypads” for more details on how to use the keypads.

Standard 4 Wire Keypad Connections
The standard installation of keypads to the Delta Controller is with 4 wires directly between the
Controller’s zone output and the keypad’s input (right side connector of the keypad), as shown in FIG. 7.
FIG. 7 Standard 4 Wire Keypad Connections
If the building was “pre-wired” for standard audio, this is the configuration they most likely intended. If
you wired (or will wire) the keypad locations yourself, this is the most common configuration.
When stripping cable for use with the Molex connector, only strip away about 1/4” (6mm) of the
insulation from each wire. The complete assembly should not have any bare wire exposed from the
bottom of the connector if possible. This is the safest, most reliable approach.

2 Wire Keypad Connections (Control Only)
In some retrofit configurations it is not feasible or possible to re-route the speaker cable through the
keypad. In cases such as this, it is possible to run a separate cable pair (CAT- 3 / CAT- 5 / CAT- 6 /
Twisted Pair / Other 2 conductor wiring) cable from the Delta Controller to the keypad device for control
purposes. This diagram shows the connections of the control signal path to the keypad and the speaker
connections directly to the Delta Controller (FIG. 8).

FIG. 8 2 Wire Keypad Connections
Keypad wiring uses just two conductors. These could easily be Cat 3/5/6 or generic 2 conductor wiring.
Use only the D (DATA) and G (GROUND) terminals for the output of this connection. Speakers connect
directly to the Delta Controller as shown in FIG. 8.
Speaker wiring connects directly to the Delta zone output. Left and Right speaker positives connect to
the L and R terminals respectively. Both speaker negatives connect to the G terminal (which will share a
connection with the G wiring to the keypad).

Multiple Keypads in a Zone
Certain situations such as large rooms or rooms with more than one common entrance may require more
than one keypad control to conveniently manage the zone. This configuration allows for 2 Matrix
keypads to be placed on the control circuit. Make sure that the second (AUX) keypad has the wire loop
cut so that it’s addressed to the Delta Controller as an auxiliary keypad, rather than a “MAIN” keypad
(FIG. 9).
Secondary Keypad wiring
Main Keypad wiring
FIG. 9 Multiple Keypads in a Zone
The main keypad wiring uses all four conductors and connects to speakers as normal. The
secondary keypad “taps off” of the D and G terminals of the main keypad input for a
secondary control point.
The secondary keypad must have the loop cut to configure it as the secondary (AUX) keypad.

Matrix Keypad plus Analog Volume Controls
In cases of split zones where more than one set of speakers are driven from the same zone output (such as
a master bath off of the master bedroom) it is sometimes desirable to place independent volume controls
in the split zones while retaining the Delta Keypad for source control and ON/OFF functions.
FIG. 10 shows the connections to a remote zone and “Autoformer” volume control devices.

Total impedance on the zone MUST NOT be below 4 Ohms!
The secondary analog volume control “taps off” of the L+, G and R+ terminals of the DELTA
CONTROLLER OUTPUT. The G terminal connects to both L- and R as shown. This allows
independent volume in each “sub zone” with the Delta Keypad being the source control and
ON/OFF switch.
The main keypad wiring uses all four conductors and then a secondary analog volume control
“taps off” of the L+, L-, R- and R+ terminals of the SPEAKER OUTPUT for the main zone.

Auxiliary Amplifier Configuration (Zone 1)
In some cases you may require more power for a given zone than the Delta Controller can provide.
FIG. 11 shows how to utilize the preamp RCA outputs on the Delta Controller for an external amplifier.
This may be useful when outdoor or large rooms make up the zone, or in situations where the number of
speakers will require a multi-channel amplifier to safely power them all.
FIG. 11 Auxiliary Amplifier Configuration
This configuration shows an external power amplifier connected to the “LINE OUT” connections on the
back of the Delta Controller. These connections are only available on Zone 1. The corresponding Zone 1
keypad would connect to the Delta Controller with only the D and G connections. The power amplifier
will handle the individual speaker connections which means the amplifier and the speakers can be placed
at distances from the Delta Controller not usually practical. It also allows an easy solution when you
simply need more power in the zone than the Delta Controller provides

Auxiliary Amplifier Configuration (Zones 2-6)
In cases where you require more power for a given zone than the Delta Controller can provide and it is
other than in Zone 1, use this diagram. It shows use of a Matrix LLC device designed to reduce the
“speaker level” output of the Delta Controller to “line level” so that it can drive an auxiliary amplifier.
This amplifier would typically be installed at the equipment rack (source end).
Remote Amplifier Configuration
In some cases, especially where the distance between the Delta Controller and the zone is unusually
long, such as another building on the property i.e. cottage-to-boathouse for example, it is sometimes
desirable to have a remote amplifier at the zone end. This diagram could also represent the Matrix LLC
device implemented so that there is a preamp level output available for a remotely mounted amplifier
elsewhere on the property. The main difference is the run of 4 conductor wire between Delta and the
Matrix LLC device (FIG. 12).
