MULTI-ROOM SYSTEM CONTROLLER RMZ-955

tions which allow linking additional RMZ-955 controllers for large systems. Depending on the design of the associated compo- nents, these pass-through source connections may alternatively be used to “share” source components with a separate home theater or audio system.

Placement

Place the RMZ-955 on a stable surface in an equipment rack or cabinet. Note that the RMZ-955 is slightly deeper than most source components (tuners, CD players, cassette decks, etc.) and should not generally be placed on top of these units.

Connections:

Make sure that you have enough room to run all the connecting cables and dress them appropriately behind the RMZ-955. Al- though we’ll explain each connection fully in following sections of this manual, glance through the following list of possible con- nections and decide how much space you’ll need.

a) Four pair of RCA interconnects – one pair from each source.

If the RMZ-955 is on an open shelf, the emitter’s signal must first travel to an IR-reflective surface (an opposing wall, for example) and then to the source component.

Keep total IR signal travel to 40' or less. Remember that it must travel to a hard reflective surface and back again.

b)Eight heavy gauge speaker cables (two for each zone).

c)Four six-conductor + shield data cables, each terminated with the proper IDC strip connector.

d)One shielded RCA to RCA interconnect for RC-5 remote control code connection.

e)One pair of RCA to RCA interconnects to power amplifiers from each corresponding zone’s “Pre-out” terminals.

f)Up to four mini-plug (3.5 mm) cables from the RMZ-955’s “Infra Red” outputs to remote IR transmitters.

g)Four more pair of RCA to RCA interconnect cables – one each to the appropriate input of the next RMZ-955 in large multi-control- ler systems.

Note: If an RSM-901 sensor display is located in the same room as the RMZ-955 controller, it is essential that the output form the front-panel IR flood emitter NOT reach the RSM-901 sensor. IR loop problems can cause intermittent operation.

IR Repeater Jacks

The RMZ-955 also has four rear panel IR output jacks for use with industry standard IR repeaters (made by Xantech and oth- ers). The use of these external repeaters on each source compo- nent is ideal in situations where output from the front panel flood IR emitter is blocked from the source components by a door, full depth shelf, etc. It is also an ideal solution when the front panel flood emitter output could reach an RSM-901. When IR repeaters are used, the front-panel flood emitter can be easily disabled.

h)Additional loudspeaker connections as required for systems us- ing more than one RMZ-955 controller/amplifier.

i)3.5 mm to 3.5 mm cable for AC “link” connections as required for systems using more than one RMZ-955 controller/amplifier.

j)Up to six “TX-FORM” terminal block jumper wires needed when cascading multiple RMZ-955 controller/amplifiers.

We STRONGLY RECOMMEND that you attach a tag or strip to each cable and wire to identify it (e.g. “To Input 3 from tape deck.”). This will help in troubleshooting as well as make future service calls or system add-ons much less frustrating.

IR Flood Emitter

The RMZ-955 has a high intensity front panel IR flood emitter de- signed to transmit commands from the remote zones to the ap- propriate source component. Although exact performance will vary, this high power transmitter has an effective operating range of approximately 40' under normal conditions.

System Wiring Considerations

Data Cable and Connectors

The data path between the RMZ-955 controller/amplifier and RSM-901 sensor/displays and RKP-901 keypads must be made with cable with six insulated conductors plus a foil and/or braided outer shield. We recommend a Belden 9536 equivalent for best results. The RMZ-955 system data connectors work only with cables using 24 gauge conductors. Make sure that all data cables conform to this requirement.

Data cable termination is via industry-standard 6 pin IDC connectors made by Methode and others. (The Methode part number is 1300-106-424.) Data cable connection instructions are found in the Installation section of this manual (see page 9).
