SYSTEM OVERVIEW
The SpeakerCraft MZC-64 System consists of four subsystems. First, the Keypads, (EZ-Pad, IMKP, MODE 3.1, not included)
can be setup in a variety of configurations to meet virtually any client requirement. They are connected via convenient CAT-5
cablewithhomerunlengthsofupto1000’(305m),tothecentrallylocatedMZC-64Multi-ZoneAudioAmplierControl-
ler and source components. The MZC-64 contains the “brains” of the system, taking key location data (button presses) from
the keypads to trigger IR, RS232 and RS485 commands to control system functions and source components. Programming
is accomplished using EZ-Tools, a SpeakerCraft developed Windows® software system. A fourth item, the LTM-1.0 Learning
TestModule,isaninstaller’stool(notincluded)forlearningandteachingspecialIRcommandsthatarenotincludedinthe
EZ-Tools Command Library.
KEYPAD CONFIGURATIONS
EZ-PAD
One keypad option for MZC-64 system control is the SpeakerCraft EZ-Pad System. EZ-Pads can be configured in single,
double or triple-gang configurations as shown in Figure 1. (Decorator style cover plates are not included. Screw-less “Snap-
On” type cover plates can also be used. Each keypad module must be ordered separately.)
Each keypad comes with a set of factory installed “default buttons” plus a good variety of additional buttons for changes
to the default configuration. The default buttons can be easily changed to meet the needs of any installation. Additional
buttons are available separately for purchase. See the SpeakerCraft Catalog and Price Sheet for the latest availabilities or call
SpeakerCraft Customer Service.

IMKP
Another option for MZC-64 System control are the SpeakerCraft IMKP Series Keypads. The IMKPs are a Euro-Design version of
the EZ-Pads that have similar functionality in a mechanical package that fits European style in-wall junction boxes. They are
available in 2 and 3 gang configurations and each includes a SpeakerCraft IR Receiver with ANS. See: IMKP-2.1/IMKP1.1
Installation Instructions for additional information. IMKP-2.1/IMKP1.1 Installation Instructions can be downloaded from
www.speakercraft.com.
MODE 3.1
The third, and best option for MZC-64 system control is the SpeakerCraft MODE 3.1. MODE 3.1 is a graphic display keypad
thatcombinestheconvenienceandcongurabilityofEZ-Pad/IMKPstylehardkeyswithgraphic‘VirtualButtons’thatcan
be created in EZ-Tools for any function imaginable. In addition MODE 3.1 displays metadata from the MZC as well as iPod
(when controlled with a SpeakerCraft MODE Base), SpeakerCraft Tuners and MODE Jukebox. MODE 3.1 requires a special
mounting bracket and bezel both of which are included with MODE 3.1. See: MODE 3.1 Installation Instructions for
additional information. MODE 3.1 Installation Instructions can be downloaded from www.speakercraft.com.

EZ-Pad Features
1. MKP-1.0/MKP-1.1 SOURCE/FUNCTION BUTTONS – Any of this set of eight buttons can be programmed as a
Source Select or transport/function button for the MZC-64. One of the eight must always be designated as a Source
Button. When the system is off, all buttons have a background green color. When a source button is pressed, it turns to
a low-level red color to show the active source and the system is on in that zone. (Backlight Timeout can be set in EZ-
Tools for EZ-Pad and IMKP. MODE 3.1 Backlight is configured in the MODE Keypad Settings Menu.)
2. KEYPAD EXPANSION TERMINAL – This 16-pin header terminal is used to inter-connect EZ-Pad modules for expansion
as needed. A 3-connector ribbon cable is packed with each NKP-1.0 and FKP-1.0 module for making these connec-
tions.
3. ADDRESS SWITCH – An unique hex address must be set for each Master Keypad when connected on a common
bus within a single zone. Unique addresses are not required zone-to-zone (one keypad per zone). It provides up to 16
addresses (0 to F).
EZ-PAD FEATURE DESCRIPTIONS
EZ-Pads come in four basic modules as shown. The MKP-1.0 and MKP-1.1 are Master Keypads and one must be used in each
MZC-64 Zone using a keypad. The MKP-1.1 features a built-in IR receiver and has one less function button than the MKP-1.0,
but are otherwise identical. The NKP-1.0 Numeric and FKP-1.0 Function key modules may be thought of as “slaves” to the
Master Keypad (they will not work alone), providing more buttons for additional numeric and function commands. MKPs,
IMKPs, and MODE 3.1s will all work right out of the box for basic functions such as Source Select /ON, Volume/Mute and
OFF. Configuration of advanced features and source control requires programming with EZ-Tools.

sourcecomponents,whenusingmultipleMZC-64’sinexpandedsystems.i.e.IfusingtwoMZC-64s,theSOURCEIR
OUTS on the MZC Slave unit would connect to the appropriate SOURCE IR LOOPS on the MZC Master unit to pass
Source IR commands between controllers from expanded zones. The IR OUTS on the Master connect to IR EMITTERS
attached to the source components for source IR control from all zones. POLARITY: TIP=SIGNAL; SLEEVE=GND.
17. IR OUT (Source) — Six, 3.5mm mini jacks, one per Source, output IR commands to external common source com-
ponents. When a source is selected, from a keypad or remote control, IR commands are routed directly to that source.
This allows selective control of multiple same-brand, same-model source components (multiple Satellite Receivers, DVD
Players etc). POLARITY: TIP=SIGNAL; SLEEVE=GND.
18. L & R LOOP (Source Left/Right Audio Loop) — Twelve, RCA jacks, two per Source, provide buffered left and right
line-levelaudiooutputsthataretypicallyusedtoloopSourceAudiosignalstoadditionalzoneinputsonSlaveMZC-64’s
in expanded systems. i.e. The L & R LOOP on the MZC Master would connect to the appropriate L & R INPUT on MZC
Slave 1. Slave 1 would then loop to Slave 2, etc. These outputs can also be used to drive local components, such as a
local surround receiver, when not used for expansion.
19. L & R INPUT (Source Left/Right Audio Input) — Twelve RCA jacks, two for each Source, provide left and right line-
level audio signal inputs for up to six external common source components.
20. IEC TYPE AC MAINS RECEPTACLE AND FUSE — One, Standard IEC 3-conductor AC line cord receptacle, connects to

1. MOUNTING HOLES — Two, keyholes, use these holes to mount the EPR-1.0 to any flat surface (usually to the studding
in the wall behind the EZ-Pad or the in-wall speakers).
2. “AMPLIFIER” EZ-CONNECT TERMINALS — Four, spring-loaded terminals connect to the amplifier L & R speaker
level output terminals. WIRE GAUGE: 14 to 28 AWG.
3. “SPEAKERS” EZ-CONNECT TERMINALS — Four, spring-loaded terminals connect to the L & R terminals on the room
speakers. WIRE GAUGE: 14 to 28 AWG.
4. RELAY COIL LEADS — This 12" (305mm) 2-conductor lead connects to the +Relay and –Relay terminals on the back
oftheEZ-Pad.Itcanbeextendedtoanylengthrequired(2000’with24AWGwire).Maintainproperpolarity.Whenthe
designated MUTE key on the connected keypad is pressed, the EPR-1.0 relay opens, thus muting the audio. The selected
source button on an EZ-Pad/IMKP will blink at a slow rate to indicate the muted condition. MODE 3.1 will display a red
MUTE at the top of the LCD.
The EPR-1.0 EZ-Pad Speaker Muting Relay Module allows local speaker muting in any room with an EZ-Pad. Example: An
MZC-64ZonePRE-OUTfeedingamulti-channelamplierforsub-zoneexpansion.Eachoftheadditional‘rooms’wouldutilize
one stereo pair speaker-level output from the multi-channel amp, have a keypad for system and source control and each
keypad would have an EPR-1.0 to mute the local speakers. All rooms in the zone would have the same ON/OFF status and
play the same source. Individual room mute could then be controlled either from a keypad or an appropriately programmed
IR Remote. EPR-1.0 is also fully compatible with IMKP and MODE 3.1.

SYSTEM PLANNING AND INSTALLATION
SYSTEM PLANNING
With all of the flexibility and options of a MZC-64 System, careful planning can save time and money for both the installer
and homeowner. A few EZ steps can help in managing this process.
1. KNOW THE PRODUCT AND ALL OF ITS CAPABILITIES — This will help in making suggestions to the homeowner
for incorporating features they may want. It will also help in being able to combat feature capabilities, or inadequacies,
of a competitive product that another Installation Company may be proposing.
2. KNOW THE HOMEOWNER — Spend some time in the home if possible, and get a feel for how the prospective client
is going to want to use the system. If the home is in the planning stage, be sure to get involved with the architect to as-
sure proper allocation of space for system components, ventilation and access to the system for service (a closet with rear
access to the system connections is ideal whenever possible).
3. DOCUMENT EVERYTHING — Whendiscussingthesystemwiththeprospectiveclient,writedownalloftheir‘wants’
in terms of how they want the system to work. Do they want doorbell paging? Do they have lots of parties and want to
‘group’zonesincommonareas?Willtheyneedanexternalhigh-poweredamplierforthepatio/poolarea?
Write everything down and review it with the homeowner to define specific system features and functions. Suggest
options for future upgrading or expansion of the system, such as additional wire infrastructure, for adding rooms to the
system long after the walls have been sealed. Use the results of the review to create a formal proposal.
4. LEAVE PRODUCT INFORMATION — Leave the client with Brochures for the MZC-64, SpeakerCraft Speakers, Ampli-
fiers and Accessories that will be specified in the proposal. (Packaging it all in a nice folder or binder is a nice touch.)
Confirm a date to review the formal proposal.
5. CONTRACT THE JOB — Get back to the prospective client with a professional, formal proposal. (There are some good
systemplanningandproposalsoftwarepackagesthatcanreallyhelpmanagethiswholeprocess.)Reviewtheir‘wants’
and show how they have been implemented in the overall system design. Inform the homeowner as to how the instal-
lation will be done. Phase 1, pull wire. Phase 2, install speakers and components. Phase 3, system programming and
tweaking. (Tying payments to the different installation phases is also something to consider. Spreading the payments can
help defuse potential sticker shock for the homeowner and also help manage cash flow for the Installation Company.)
If all is acceptable to the homeowner, have them sign the proposal as a formal contract and set a start date for work to
begin. (Having the homeowner sign the proposal as a contract can help avoid problems during installation in that the
system and work to be done is defined. Anything not defined in the contract is extra.)
6. DOCUMENT THE SYSTEM FOR INSTALLATION — If using one of the planning and proposal software packages
available from third parties, this part of the process will already be done. If not, carefully document the system for whole-
house wiring. Show all runs of CAT-5 for control, coax for video, two-pair 18-14AWG stranded for speakers and addi-
tionalwiresfordoorbell/paging,andanythingelseinthesystemthatneedstohavewirepulledthroughthewalls.Don’t
leaveanythingout.Thepersonpullingthewireisn’tnecessarilythesamepersonthatsoldthesystem,soifthesystem
hasn’tbeenproperlydocumented,criticalfeaturewirecomponentscouldbeleftout.
Detail what components will be installed in each room, and where they will be installed, including the control system,
speakers, TV/Video Display and any other sub-system interfaces by room, by component, by brand and by model. Be
sure the person pulling the wire has this information to cross reference the wires pulled and to where.
7. DOCUMENT SYSTEM FUNCTIONALITY — Document all system functions by system, by zone, by source and any
special features that have been included. Be sure to include functions such as how the system turns on when the first
source is selected, and how it turns off when the last zone shuts down. Include all special functions such as switch
closures for lifts and screens and EPR-1.0 mute commands for zones with multi-channel amps for sub-zone expansion.
Include Tuner preset preferences if applicable. Include Paging functions. All system functions should be detailed. The
persondoingthesystemprogrammingisn’tnecessarilythesamepersonwhosoldthesystemorpulledthewire.Besure
everyone involved in the installation and setup knows what the system is and how it is supposed to work.

MZC-64 Hardware Installation Instructions Page 15
8. ACQUIRE ALL SYSTEM COMPONENTS — Set up the system, and program and test all functions before tak-
ing the electronics to the job site. This can save valuable time in assuring that all system components work and the
system is functioning as designed. Connecting and testing the system prior to installation will also help assure that all
parts and pieces that will go into the system are in hand, so time is spent on the job site and not running around town
shopping for parts or not being able to finish the installation while waiting for an air shipment of a ten dollar part.
9. HEAD-END CONSIDERATIONS — The system head-end should be in a convenient, central location that provides
easy access for the user, to be able to load discs, video tapes etc. The location should also be accessible for service and
ideally would have either have rear access to the system connections or a pull-out rack that allows access to system
connections. All system wire runs should terminate at the head-end. There should be sufficient mounting space for all
system components and the wires and cables that connect them. Leave plenty of room for airflow for proper ventilation
or system components could be damaged. Too tight of a space that does not leave room for system wiring or a poorly
dressed system can cause thermal problems. Wires jumbled in around system components can act as an insulator or
block free airflow which can damage the components from overheating. Incorporate a proper ventilation system using
cooling fans (SpeakerCraft ESC-1) for systems with external amplifiers or other components that generate excess heat.
When possible, leave extra space for future expansion of the system for additional zone and source components.
10. ZONE CONSIDERATIONS — Identify all room components and their locations. Typically, a keypad would be mounted
near the entry to a room. If the room orientation of where the TV/Monitor and speakers are located leaves the keypad
behind the user, an additional IR receiver on the same wall as the TV and speakers will help make controlling the system
more user friendly. Be sure to include an appropriate wire run for the IR receiver. Additional wire runs for controlling lifts,
screens and drapes should also be considered. Try to avoid mounting keypads and IR receivers in locations that will be
exposed to direct sunlight. Leave extra wire at keypad and in-wall speaker locations so these components can be easily
removed without pulling on wires and possibly have them fall down inside the wall, should service be necessary.

SYSTEM INSTALLATION
WIRING
Once the system has been defined and the contract signed, work can begin. The first part of the system to be installed is the
wiring infrastructure. With all of the flexibility and options of a MZC-64 System, maintaining clear, accurate documentation of
the location (the house) and the system will help in managing a smooth installation. Always be sure to pull and test the wires
needed for the system as specified, and always consider pulling extra wire for fall-back in the event something gets damaged
during drywall installation. Beyond that, pulling additional wire to rooms not specified in the system can help down the road,
should the homeowner decide to add rooms to the system at a later date, or increase flexibility within already active rooms.
There are certain types of wire that are default requirements and there are others that are used for the system optional fea-
tures.
KEYPADS
SpeakerCraft EZ-Pads have seven-position spring clip terminals for wire connections. Five of these terminals are used for
connection to the MZC-64 Keypad Terminals. CAT-5 can be used with or without RJ45 connectors on the keypad end,
but must be terminated with a RJ45 plug on the MZC end. Be sure to follow the color coding pin-outs for the keypad
connections and use the pin-out for the RJ45 connection to the MZC as shown in section: EZ-Pad Configuration. Stan-
dard wire can also be used for retro-fit installations provided there are at least 5 conductors available. Use of SpeakerCraft
RJA-1.1 RJ45 to Wire Pin Adaptors is recommended for EZ-Pad connections. See: IMKP Installation Instructions and

EZ-PAD CONFIGURATION
1. As received from the factory, the MKP-1.1 EZ-Pads have a preinstalled set of buttons that may not match the system
being installed. To change the source and function button arrangement, release the tabs, Figure 11, and remove the
decorator insert panel, exposing the key buttons. (Figure 12.)IMKP and MODE 3.1 buttons can also be changed.
See: IMKP Installation Instructions and MODE 3.1 Installation Instructions for additional information.
Figure 12
Remove Decorator Insert Panel
Figure 11
Release Tab
2. Starting with the Zone 1 MKP-1.1 (Master Keypad), and using
the extra buttons supplied, if needed, move and place the
source and function buttons in an arrangement matching the
system being installed. (Refer to Figure 13) When finished,
replace the decorator insert panel over the buttons, being care-
ful to see that the buttons align correctly with the panel open-
ings. Press the panel down until the tabs “snap” into place.
3. Repeat these steps for each of the other zone Master Keypads.
Note that each zone can have its own unique configuration,
however, it is best to keep them as similar as possible to simplify
system programming and operation.
4. Repeat steps 1-3 to configure the buttons on the Numeric and
Function keypads (not included) as needed.
NOTE: The Numeric and Function keypads will not work on their own. They must be connected to a Master Keypad
using the 3-Connector Ribbon Cable included with each NKP-1.0 and FKP-1.0. The cable is symmetrical so it can be
connected with the red striped side up or down, to best fit the configuration. Figure 14 shows it connected so that
the MKP Master Keypad will be to the right of the NPK Numeric and FKP Function keypads when mounted, whereas
Figure 15 places the MKP to the left.
