5. DOORBELL/STATUS IN 1 & 2 – Two, 3.5mm mini jack trigger inputs work in conjunction with the PHONE and VIDEO PAGE IN
jacks, items 3&4. When triggered, the Page Inputs can be turned on in selected zones as programmed in
EZ Tools. If Paging
is not required, these jacks can also be programmed as STATUS INPUTS for power management of Source or Zone
components.
POLARITY: TIP= +V; SLEEVE=GND. INPUT VOLTAGE: 3-30V AC or DC to trigger the ON condition. Voltage must
drop below 1V AC or DC for OFF.
6. CONTROL PORT – One, 3.5mm 4-circuit mini jack used for all Controller and Keypad programming. It also accommodates
factory firmware upgrades in conjunction with the
FIRMWARE UPGRADE ON/OFF SWITCH.
See:
EZ Tools MZC Programming
Instructions for additional information. This port also serves as a bi-directional RS-232 serial interface allowing the MZC-66
system to be controlled by external devices.
7. FIRMWARE UPGRADE ON/OFF SWITCH – One, two position switch enables the MZC-66 Control Port for Firmware Upgrades. See:
EZ Tools MZC Programming Instructions
for additional information.
8. COMMON IR OUTPUT – One, 3.5mm mini jack outputs all IR commands from IR sensors and Keypads regardless of zone origin.
POLARITY: TIP=SIGNAL; SLEEVE=GND.
9. HI/LO SWITCH – One, two position switch, sets high or low IR power output to the Common IR Output jack. Set to the LO
setting when driving standard low power emitters (SpeakerCraft IRE-1.0, 2.0, 3.0 and 4.0). Set to
HI when driving a high power
emitter (SpeakerCraft IRE-5.0 Blaster) for teaching IR commands into learning remotes.
HI OUTPUT: 110mA; LO OUTPUT: 13mA.
CAUTION:
The
HI
position will smoke low power emitters!
10. COMMON STATUS OUT – One, 3.5mm mini jack will go high (+12V DC) when any zone is turned ON and will go LOW (under 1V
DC) when the last zone is turned OFF.
POLARITY: TIP=+12V DC; SLEEVE=GND. MAX OUTPUT: 100 mA at 9.5V DC.
11. VIDEO OUTPUTS – Six, RCA jacks provide a dedicated composite video output, one for each Zone. 75 ohm outputs provide
matched line impedance for high quality video over RG6 coax for lengths up to 500 feet.
12. IEC TYPE AC MAINS RECEPTACLE AND FUSE – One, Standard IEC 3-conductor AC line cord receptacle, connects to included AC
power cord. Also houses the rear panel replaceable AC mains fuse (T5AL 250V).
13. L, R & V LOOP (Source Left/Right Audio/Video Loop) – Eighteen, RCA jacks, three per Source, provide buffered left and right
line-level audio and composite video outputs that are typically used to loop Source Audio signals to additional zone inputs
on Slave MZC-66’s in expanded systems. i.e. The L, R, V LOOP on the MZC Master would connect to the appropriate L, R, V
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.
14. L, R & V INPUT (Source Left/Right Audio/Video Input) – Eighteen RCA jacks, three for each Source, provide left and right line-
level audio and composite video signal inputs for up to six external common source components.
15. IR LOOP – Six, 3.5mm mini jacks, one per Source, provide connections for an IR signal path for external common source
components, when using multiple MZC-66’s in expanded systems. i.e. If using two MZC-66s, 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.
16. IR OUT (Source) – Six, 3.5mm mini jacks, one per Source, output IR commands to external common source components.
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.
17. IR OUT (Zone) – Six, 3.5mm mini jacks, one per zone, provides dedicated Zone IR output for exclusive control of a specific
zone component. (i.e., a dedicated satellite receiver or DVD player, that cannot be controlled from any other zones).
POLARITY: TIP=SIGNAL; SLEEVE=GND.
18. VC/NVC –
Six, two-position switches, one per zone, switch the PRE-OUT jacks to
VC
- internal Volume Control (variable, zone
volume controlled by keypads or IR remote) or
NVC
- No Volume Control (fixed, zone volume controlled by in-wall volume
control or volume control on an external device such as an A/V Receiver). In either case, the tone control action remains
available for room “EQ” settings.
19. L & R SPEAKERS – Six, removable screw-down connectors, one terminal per zone, provide quick connection of the internal
amplifiers to Zone stereo speaker pairs.
WIRE GAUGE: 14 to 24 AWG.
20. EZ-PAD – Six, removable screw-down connectors, one per zone, connect zone keypads to the MZC via CAT5 or better. Standard
five conductor wire (24-14AWG, stranded, non-sheilded) can also be used in retro-fit applications. Allows runs of up to 1000’. See
section:
Keypad Connections
for additional information.
21. L & R PRE-OUT – Two, RCA jacks, one pair per Zone, provide left and right line-level audio outputs for driving external high-
power/audiophile two-channel amplifiers in large or outdoor zones or a critical listening zone, or driving a multi-channel
amplifier for additional rooms, (sub-zone expansion) where needed.
