Niles Audio ZR-4 manual Connect the Global 12V OUT, Connect the HT Home theater Sync if Needed

Page 18

CONNECT THE GLOBAL 12V OUT

The Global 12V Out triggers an external device whenever a Zone is turned on. A common use would be to turn on a 12V trigger-equipped Niles Systems Integration Amplifier connected to the Zone 4 pre-out jacks. The Global 12V out can also be used to trigger a Niles AC-3

Voltage-Triggered AC Power Strip to automate power turn-on and turn-off of connected sources.

CONNECT THE HT (Home theater) SYNC IF NEEDED

If the ZR-4 MultiZone Receiver Kit is going to share audio source components with a separate home theater system, it is important to use the HT (home theater) sync connector. A voltage signal from the home theater receiver allows the ZR-4 MultiZone Receiver to know that the home theater receiver is on and that the ZR-4 MultiZone Receiver should not go into standby, even if all of its zones are shut off, until this voltage signal is no longer present. Use a 3.5mm tip-positive connector (FG00933). One end connects to the HT Sync port on the ZR-4 MultiZone Receiver, the other end to a trigger output (or similar) on the home theater receiver. If a trigger output is not available on the home theater receiver, an alternate is the Niles CS12V Current Sensing 12V Trigger (FG01173). When the power cord of the home theater receiver is connected to the current sensing outlet on the CS12V and the receiver is turned on, the CS12V sees the additional current draw and sends out a 12V trigger via the 3.5mm to 3.5mm cable.

CONNECT EXTERNAL CONTROL IF NEEDED

The ZR-4 MultiZone Receiver can be externally controlled in two ways: RS-232C and IR.

RS-232C

The ZR-4 MultiZone Receiver is equipped with RS-232C serial communication. This allows the receiver to be monitored and controlled by an external control system such as the Niles iC2, or similar control and automation products. The RS-232C jack uses a 3.5mm stereo plug with standard TRS (Tip, Ring, Sleeve) configuration of Transmit, Receive, and Ground. This may require the installer to custom-make the RS-232C control cable. Most RS-232C control systems use a male DB9 connector, a female DB9 connector, or a 3.5mm stereo jack.

Manufacturers can provide a protocol document (usually from their Tech Support Department), which will have the necessary information to custom build the RS-232C control cable. (Figure 15)

IR In

The ZR-4 MultiZone Receiver can also be controlled by a programmable/learning IR remote control system. Use the IR control port to connect a Niles IR Sensor to receive the IR signals from the IR remote control.

Connect THE MAIN POWER CABLE

The ZR-4 MultiZone Receiver is equipped with an IEC Power Receptacle. A supplied, removable power cable is attached to this two-pin Power Receptacle and then plugged into an AC wall outlet. This is the AC power disconnect for the ZR-4 MultiZone Receiver and should remain accessible during use. A surge suppression device from a top-quality manufacturer such as Panamax® is recommended to protect the equipment from potentially harmful power surges and spikes.
