MULTI-ROOM SYSTEM CONTROLLER RMZ-955

Installation: RMZ-955 Controller

This section covers all hardware installation and configuration issues related to the RMZ-955 controller, including wiring con- nections for AC power, source connections, speaker connec- tions, pre-amp connections, data cable connections to the remote zones, Infrared control connections, and special features such as the paging feature. The next section of the manual (see page 12) covers similar topics related to the installation, wiring, and hardware configuration of the zone control devices – the RSM-901 Sensor/Display and the RKP-901 Keypad.

For the sake of simplicity, these two sections cover the installa- tion of a basic 4-zone system with a single RMZ-955 controller, since this is the most typical system configuration. There is a separate section Installation: Multi-controller Systems (page 15) that covers installation, wiring, and configuration topics related to larger, more complex systems with multiple RMZ-955 control- lers.

The switched outlet provides the mechanism for “powering up” or “powering down” all of the source components from the re- mote zones. We recommend plugging the AC power cords from the source components into the switched outlet on the back of the RMZ-955.

Rotel RLC-900 AC line conditioner/switcher

We strongly recommend the use of the RLC-900 AC line condi- tioner/switcher to improve both the performance and convenient operation of all system components. The RLC-900’s benefits in- clude increased protection from AC power line surges and im- proved system AC power management for proper turn-on and turn-off sequences.

To incorporate the RLC-900, follow these steps:

a)Plug all system source components into the RLC-900’s “Digital Equipment” or “Accessories” outlets as appropriate.

b)Plug the RMZ-955’s AC power cord into the RLC-900’s “UNSWITCHED” outlet.

AC Line Connections

AC for the RMZ-955

Plug the RMZ-955 controller/amplifier into an unswitched AC source only, i.e. a wall outlet. It is essential for proper system op- eration that the RMZ-955 be plugged into a constant source of AC power, since it has “stand-by” circuitry that must receive power for full control from any zone at any time.

We recommend a powerline filter as the RMZ-955 contains a number of microprocessor ICs that may benefit from the extra protection afforded by a quality filter/surge protector.

AC for Source Components

The RMZ-955 has two rear panel AC convenience outlets, one switched and the other unswitched. These may be used to sup- ply power for components used with the RMZ-955. Each outlet carries a maximum load rating of 100 watts.

Unswitched AC outlet: The RMZ-955’s Unswitched AC outlet supplies AC current whenever the RMZ-955 is plugged into a live AC source. This outlet is NOT controlled by the setting of the RMZ-955’s front panel power switch.

Switched AC outlet: This outlet provides a mechanism for con- trolling AC power to other components, such as source compo- nents. When the RMZ-955’s front panel switch is Off, the switched AC outlet is also off. Even when the front panel switch is turned On (i.e., when the RMZ-955 first powers up to “Standby” mode), the switched outlet remains off until the RMZ-955 receives a zone activation command from one of the remote zones. The switched AC outlet then remains on until the front panel power switch is turned Off or the RMZ-955 receives a “system shutdown” command from a remote zone.

c)Plug the RLC-900’s “Control Cord” into the RMZ-955’s SWITCHED outlet.

d)Plug the RLC-900’s “Main Power” cord into an unswitched AC outlet such as a wall receptacle, etc.

When a system activation command is sent from a remote zone, the RLC-900 turns on all source components automatically.

Special AC features

Some source components power up in a standby mode when AC power from a switched outlet turns them on. These components require a separate command to fully activate them. The RMZ-955 has a built-in software function, called “power toggle” that can handle this “power up” sequence, if necessary. This feature is fully described in the System Set-up & Programming section of this manual on page 22.
