DOORBELL/STATUS
Loop the Doorbell/Status Trigger Inputs using standard 3.5mm (
1
⁄8”) Y adaptors to simultaneously trigger the Page Inputs
(Doorbell/Status IN) on multiple MZC-66’s.
NOTE 1: This application requires standard Y adaptors. DO NOT use the SpeakerCraft SAC-1.0 Y Adapter. The SAC-1.0
has ‘steering’ diodes that will interfere with the signal path in this application.
NOTE 2: These inputs will not function without proper confi guration in EZ-Tools.
1. Terminate the Trigger Source wire with a 3.5mm mini plug. POLARITY: TIP=+V, SLEEVE=GND.
2. Connect Trigger Source to a Y adaptor as shown in Figure 20.
3. Daisy-chain the Y adaptors to all MZC-66’s in the chain as shown in Figure 20.

COMMON IR OUT
The Common IR Out jacks from multiple MZC-66’s can be paralleled and looped using standard 3.5mm (
1
⁄8”) Y adaptors for
IR control of a common device (not connected to one of the Source Inputs) from any MZC-66 in the chain.
NOTE: This application requires standard Y adaptors. DO NOT use the SpeakerCraft SAC-1.0 Y Adapter. The SAC-1.0
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-66s in the chain as shown in Figure 21.
2. Connect an IR emitter to the Y adaptor assembly as shown in Figure 21. Set the LO/HI Common IR Out Switch
to LO.
3. Attach the IR emitter to the device to be controlled over the IR eye on that device.
