EXPANDED SYSTEMS
Up to four MZC-66s can be “daisy-chained” together to create systems with up to 24 Zones. The fi rst MZC-66 in the chain is
referred to as the Master and the subsequent MZC-66’s are referred to as Slaves. System Zone numbers correspond to the
MZC-66 Master and Slaves as follows:
MZC-66 Master Zones 1-6
MZC-66 Slave 1 Zones 7-12
MZC-66 Slave 2 Zones 13-18
MZC-66 Slave 3 Zones 19-24
A CAT-5/RJ45 CABLE MUST BE USED TO LOOP SYSTEM FUNCTION DATA AND METADATA BETWEEN THE MZC-
66 MASTER AND SLAVES.
MZC-66’S CANNOT BE DAISY-CHAINED TOGETHER WITH MZC-64’S OR MZC-88’S IN THE SAME SYSTEM!
All External Common Source Components get connected to the Source Inputs on the Master. The external source
audio and video signals are then looped from the Master to the Slave MZC-66’s for audio and video distribution to expanded
zones. External Source IR control is looped in a reverse direction from the highest numbered Slave back to the Master and
output from the Master to the external sources via IR emitters.
Phone/Video Paging signals require an audio/video distribution amp to feed the telephone audio and/or camera video
signals to each of the MZC-66 Master and Slaves. The Doorbell/Status Trigger Inputs must be looped to trigger all MZC Master
and Slave Page Inputs.
The Common IR Out and Common Status Out jacks must be looped for control of common IR or voltage controlled devices.
In an Expanded System, when connecting MODE Base(s) and MODE Jukebox(es), it will be necessary to add at least
one SpeakerCraft RSA-1.0 to create a RS485 bus from one of the MZC Expansion Ports. (Refer to Figure 17) This will provide
two-way communication with iPod(s) and Jukebox(es) for Serial Control to the devices and metadata return to the MZC for
display on MODE Keypads.
INSTALLATION
Additional space should be allocated for installation of each additional MZC-66. Leave at least 3-4 inches above and below
each Controller for proper air fl ow for cooling. Mounting MZC-66s at the top of an equipment cabinet is recommended to
reduce source components exposure to excess heat. Use cooling fans (SpeakerCraft ESC-1) when necessary.
CONNECTIONS AND CONFIGURATION
KEYPADS
1. Connect Keypads and IR receivers to the appropriate MZC-66 EZ-Pad Zone terminals. Maintain proper polarity and check
all connections prior to powering up the system. (Refer to Figure 18)
AUDIO/VIDEO External Common Source Components
1. Connect one, quality, RCA-RCA stereo A/V patch cable from 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 INPUT
on the MZC-66 MASTER.
2. Connect one, quality, RCA-RCA stereo A/V patch cable from the LOOP OUT on the MZC-66 MASTER to the same num-
ber SOURCE INPUT on the next MZC-66 Slave in the chain. (Master to Slave 1, Slave 1 to Slave 2, etc.)
3. Repeat Steps 1-2 for all external common source components. (Refer to Figure 17)
IR-External Common Source Components
1. Connect one 3.5mm mini-mini patch cable (SpeakerCraft PTP-1) from the IR OUT of the last Slave, (Slave 3 if using 4
MZC-66s) to the same source number IR LOOP jack on the next MZC-66 in the chain (Slave 3 to Slave 2, Slave 2 to
Slave 1, Slave 1 to Master) for each external common source component to be controlled via IR.
2. Connect an IR emitter to the SOURCE IR OUT on the MASTER and attach to the appropriate source component over
the IR eye of that component.
