COMMON STATUS OUT
The Status Out jacks from multiple MZC-88s can be paralleled and looped using standard 3.5mm (
1
⁄8”) Y adaptors for 12 Volt
DC control of a common device when any zone in the system is turned on.
NOTE: This application requires standard Y adaptors. DO NOT use the SpeakerCraft SAC-1.0 Y adaptor. The SAC1.0 has
‘steering’ diodes that will interfere with the signal path in this application.
1. Daisy-chain the Y adaptors to the Common IR OUTS on all MZC-88’s in the chain as shown in Figure 26.
2. Connect a trigger wire to the Y adaptor assembly as shown in Figure 26.
3. Terminate the trigger wire as appropriate. Maintain proper polarity. Check connections prior to powering up the system
- Improper connection of a voltage trigger can damage system components.
4. Connect the trigger wire to the device to be triggered.

MZC-88 INTERNAL TUNER SETUP
The MZC-88 has two built-in AM/FM Tuners that allow programming of up to 10 AM or FM Stations per Tuner per Zone. Each
Zone’s presets require programming by Tuner and by preset. That is, all presets in all zones are individually set. This ultimately
allows tremendous flexibility in that different users can have different favorite stations programmed in different zones. One
zone may be all rock stations, while another is a mix of jazz and classical while another might be a mix of news, talk, sports
and a variety of music stations. Tuner Presets can only be programmed from the MZC-88 Front Panel controls. Programming
the keypads for control of the tuners must be done in EZ-Tools.
With two tuners, up to two different stations can be playing in two different zones at the same time. The tuners can be
setup for priority lockout so that the first zone to select a tuner has exclusive control until that zone selects another source or
is turned off. In priority lockout, other zones can select and monitor a ‘locked’ tuner, but cannot control it until it is released.
With no priority configuration to the tuners, any zone can select and control either tuner at any time.
