MULTI-ROOM SYSTEM CONTROLLER RMZ-955
6
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.
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.
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.
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.

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