Page 30 MZC-88 Installation Instructions
HEAD-END
The MZC-88, external source components, and additional amplifiers will typically be installed at the System Head-End. They
can be mounted on shelves in a wall unit, entertainment center or closet, or rack mounted in a standard 19” rack mount
system. Source components such as DVD/CD players and VCR’s should be installed so the user has easy access for loading
discs and tapes.
Though heavy, the MZC-88 (and additional amplifiers if used) should be mounted at the top of the equipment rack so heat
generated by the controller will not affect the other system components. This will also allow cooler air to rise up through
the equipment rack with the hottest devices exhausting out the top. Use cooling fans such as the SpeakerCraft ESC-1.0 rack
cooling sysetm, to push/pull air through the equipment rack if temperatures exceed the specifications of any of the system or
source components. Properly exhaust hot air into an attic space or outside the structure. (Be aware of and comply with any
building codes that may apply to ventilation.)
Always leave adequate space between system and source components for airflow. Failure to do so can cause damage to the
components from overheating. Never block the vent holes on the top or bottom of the MZC-88. Blocking the vent holes will
cause the controller to overheat. Never remove the MZC-88 Controller’s feet when shelf mounting. This will block the vent
holes on the bottom of the unit and will cause the controller to overheat. When using multiple MZC-88s in a system DO NOT
stack the MZC-88 Controllers directly on top of each other. Leave at least 3-4” between controllers, and if rack mounting, use
at least one, double rack-space vent panel between controllers to assure proper airflow.
The KCM-1.0 can be mounted on the shelf behind the controller, or on a cabinet or closet side wall as space allows. Mount-
ing the KCM-1.0 behind the controller can help maintain ‘bundled’ zone control, video and speaker wires for neat wire
management, given sufficient shelf space behind the MZC-88, (approximately 4-6”). Be sure to leave enough space for the
MZC-88 to be removed for service if needed.
INSTALLATION
CONNECTIONS - HEAD END
This section provides information for connections to a single MZC-88 Controller. See Section: EXPANDED SYSTEMS for
information on connections to multiple MZC-88’s in expanded systems. All system and source components should be installed
before making any connections. To prevent electrical shock and possible damage, be sure all components are disconnected
from AC power while making connections.
KEYPADS
1. Connect each keypad run to the appropriate EZ-PAD Zone on the KCM-1.0. When not using RJ45 connectors, be sure
to maintain consistent color code when making connections . When using RJ45 connectors, be sure the recommended
RJA-1.1 adaptor pins are oriented properly. See Sections: WIRING and EZ-PAD CONFIGURATION for additional informa-
tion.
2. Connect the SCSI cable to the 8-ZONE KEYPAD OUTPUTS terminal on the KCM-1.0 and 8-ZONE KEYPAD INPUTS terminal
on the MZC-88 Rear Panel.
EXTERNAL SOURCE COMPONENTS
AUDIO/VIDEO
1. Connect the L & R line-level audio and COMPOSITE video OUT of each external source component to the appropriate
L & R line-level audio and composite video SOURCE IN on the MZC-88 Rear Panel. Use quality A/V RCA-RCA cables with
gold connectors.
EMITTERS (SOURCE)
1. Carefully attach a SpeakerCraft IR Emitter (Models: IRE-0.5, 1.0, 2.0, 3.0, 4.0) over the IR eye on the front panel of each
external source component to be controlled via infrared.
2. Carefully pull the emitter wire to the back of the MZC-88. Do not block accesses for discs and tapes. Do not pinch emitter
wires between components.
