MZC-88 Installation Instructions Page 33
4. Set the HI/LO switch to LO.
IR BLASTER
1. Appropriately position a SpeakerCraft IR BLASTER (Model: IRE-5.0) to saturate an area of common source components to
be controlled via infrared.
NOTE: This application is not recommended if there is any duplication of source components (multiple same-brand,
same-model DVD players or Satellite Receivers, etc) or zone-specific devices that could be affected by Blaster output.
2. Carefully pull the Blaster wire to the back of the MZC-88. Do not block accesses for discs and tapes.
3. Connect the 3.5mm mini plug to the COMMON IR OUT jack.
4. Set the HI/LO switch to HI.
COMMON STATUS OUT
1. Connect to the 12V or CONTROL IN terminal on a device such as a switched power strip, that is to be activated when
any zone in the system is ON.
2. Terminate and connect to the controlled device as appropriate.
3. Connect to the COMMON STATUS OUT using a 3.5mm mini plug. POLARITY: TIP=+12VDC; SLEEVE=GND.
STATUS IN
1. Connect the 3-30V control voltage OUT from a sensing device or other component control out to any of the STATUS IN
jacks to trigger an event for source power management or other system function.
2. Terminate and connect the device end as appropriate.
3. Connect to one of the STATUS IN jacks with a 3.5mm mini plug. When using the Status In jacks for power management
of external common source components, it is suggested that the Status In jack number match the source input number
to help simplify connections and programming. POLARITY: TIP=+12V; SLEEVE=GND.
4. Repeat steps 2-3 for all external common source components that require power management (i.e. they do not have
discrete IR ON/OFF codes.)
NOTE: The Status In jacks will not function without proper configuration in EZ-Tools.
ZONE PRE-OUT
1. Connect to the L&R line-level audio IN on an external high-power or multi-channel amplifier as needed for large rooms or
sub-zone expansion. Different applications require proper setting of the associated VC/NVC SWITCH. Some applications
will utilize the on-board zone pre-amp volume control (VC-variable, zone volume controlled by keypads or IR remote)
while others will use in-wall volume controls (NVC-fixed, zone volume controlled by in-wall volume control or the volume
control on an external device such as an A/V Receiver). See Section: External Amplifiers for additional information.
HIGH-POWER, TWO CHANNEL AMPLIFIER - VC, VARIABLE OUTPUT
1. Connect the MZC-88 L&R ZONE PRE-OUT to the L&R line-level audio IN on the two-channel amplifier 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-88 L&R ZONE PRE-OUT to the L&R line-level Main Bus IN on the multi-channel amplifier 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 dedi-
cated zone 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 the
emitter wire between components.
3. Connect the 3.5mm mini plug to the appropriate ZONE IR OUT jack.
120V 60HZ 3A
1. Use the included IEC three-conductor power cord to connect the MZC-88 to an UNSWITCHED 110V AC outlet.
CAUTION: Do not connect AC power until all system connections have been made and confirmed and the system is
ready for operation.
