Page 26 MZC-66 Hardware Installation Instructions
Keypads should typically be located near a door or entry point to a room. Avoid mounting keypads, IR receivers, volume
controls or any other control devices in areas of high moisture such as sinks, showers, bathtubs etc. Care should be taken to
avoid mounting Keypads and IR receivers in locations subject to direct sunlight. Sunlight can interfere with system operation
and, in time, cause deterioration to the keypad and trim plate materials.
WARNING: Never mount a keypad, IR receiver or volume control in the same J-box as high voltage devices. This can affect
system performance and is a violation of electrical codes in some areas. (Be aware of local electrical and building codes.
These codes can affect the type of J-boxes permitted, mandate wire specifi cations and regulate other aspects of the installa-
tion that may not pass inspection if necessary.)
INSTALLATION - ZONES
CONNECTIONS - ZONES
KEYPADS
1. Connect each Keypad cable run to the appropriate Zone Keypad. When not using RJ45 connectors, be sure to maintain
consistent color code when making connections . When using RJ45 connectors, be sure the RJA-1.1 Adapter pins are
oriented properly. See Sections: Wiring and EZ-Pad Confi guration for additional information. Also see: IMKP Instal-
lation Instructions and MODE 3.1 Installation Instructions for additional information on connections to those
models.
2. Install each Keypad into a proper low-voltage J-box and fi nish with an appropriate trim plate (Not included with EZ-Pad).
SPEAKERS
DIRECT SPEAKER CONNECTION TO MZC-66 OR AMPLIFIER
1. Connect Zone Speakers L+,L-/R-,R+ OUTPUTS from the MZC-66, or an external amplifi er, to the appropriate Zone
Speaker pair.
2. Strip approximately
1
⁄4 inch (6mm) of each lead and twist the stripped ends so there are no loose strands that can cause
shorts.
3. Connect as appropriate to the L+,L-/R-,R+ Terminals on each speaker.
4. Visually check for loose ends. Lightly pull the wire to confi rm connection.
5. Install speakers into dry-wall cut-outs or SpeakerCraft InstaLLock™ New Construction Brackets (if used) as appropriate.
1. Connect the MZC-66 L&R Zone Pre-out to the L&R line-level audio IN on the two-channel amplifi er to be used
(SpeakerCraft BB2125). Use a quality stereo RCA-RCA audio cable with gold connectors.
2. Set VC/NVC Switch to VC (Variable output. Zone volume will be controlled with a keypad or IR remote.)
SUB-ZONE EXPANSION, MULTI-CHANNEL AMPLIFIER - NVC, FIXED OUTPUT
1. Connect the MZC-66 L&R Zone Pre-out to the L&R line-level Main Bus IN on the multi-channel amplifi er to be
used (SpeakerCraft BB1235). Use a quality stereo RCA-RCA audio cable with gold connectors.
2. Set VC/NVC Switch to NVC (Fixed output. Sub-zone volume will be controlled with in-wall volume controls.)
ZONE IR OUT
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 a
dedicated zone source component to be controlled via infrared.
2. Carefully pull the emitter wire to the back of the MZC-66. Do not block accesses for discs and tapes. Do not pinch the
emitter wire between components.
3. Connect the 3.5mm mini plug to the appropriate Zone IR Out jack.
120V 60Hz 1.8A
1. Use the included IEC three-conductor power cord to connect the MZC-66 to an Unswitched 120V AC Outlet.
CAUTION: Do not connect AC power until all system connections have been made and confi rmed and the system is
ready for operation.
