Getting Started
The Rotel RMZ-955 Multi-Room Control System distributes audio
signals from a single set of source components to as many as
four separately controlled remote zones or listening areas. The
centrally located RMZ-955 controller/amplifier contains source
selection, microprocessor controlled communications circuitry
and independent preamplifier/power amplifiers for all zones.
Controlling the Remote Zones
Users can select either of two ways to control remote zone op-
eration. The first is the RR-952 hand held remote. This generates
infrared (IR) control pulses read by the wall-mounted RSM-901
sensor/display. The RSM-901 sensor/display then transmits com-
mands to the RMZ-955 through hard-wired connections.
The second method uses the wall-mounted RKP-901 keypad to
transmit commands directly to the RMZ-955. The RKP-901 is also
hard-wired to the RMZ-955 controller/amplifier.
Users can select a combination of sensor and keypad operation
for any zone. The system accepts inputs from up to three sensor/
displays and three keypads (for a total of six input devices) per
zone.
System Flexibility
The Rotel RMZ-955 Multi-Room Control System is exceptionally
flexible. In addition to the RMZ-955 controller/amplifier, a simple
two zone system might include just one RR-952 hand held con-
troller/RSM-901 IR sensor/display combination for one zone and
one RKP-901 keypad in the second.
In a more elaborate configuration, a single RMZ-955 accepts
commands from four separate zones via twelve IR sensor/dis-
plays and twelve keypads.
Up to four RMZ-955 controllers can be linked together for a sys-
tem with as many as sixteen independent zones.
System Highlights
• Keypad or handheld remote operation of source components. No
programming required – built-in codes for Rotel and other popu-
lar components.
• Single button operation for source selection and “play”.
• Full user control, including system standby from any zone.
• Built-in Paging input with muting in selected zones.
• Near-universal Infra-red repeating system. Remote control avail-
able even when a zone is not active.
• Alarm clock function with independent wake-up in each zone.

The RMZ-955 Controller/Amplifier is the heart of the RMZ-955
Multi-Room Control System, featuring:
• Four separate microprocessor-controlled stereo preamplifier/
power amplifier sections, one for each remote zone
• RCA inputs for up to four sources
• “Loop through” RCA outputs which allow multiple RMZ-955 con-
trollers to be linked together for large systems up to 16 zones.
• RCA line level preamp outputs for use with external amplifier
systems. These outputs can be internally configured to provide a
variable level signal or a fixed level signal.
• Screw-type quick connect speaker outputs
• Control data input for each zone is via industry-standard 6 pin
Methode connectors
• 3.5 mm stereo jack “AC Link” connections for full system control
from any zone in large, multi-controller systems
• RCA output jack for RC-5 remote control protocol components
• High power front panel IR flood emitter to transmit remote zone
commands to associated source components
• Four mini-plug IR repeater outputs
• Two polarized AC convenience outlets with 100 watts capacity
each: one switched to allow easy remote control of total system
power if desired, the other unswitched
• Front panel LED indicators for Power On/Off, zone status, com-
mand pulse processing

System Planning
The RMZ-955 is designed to be used as a stand-alone control
center for a multi-zone distribution system using dedicated
source components. It features loop-through source connec-

5
RR-952 IR Remote Control
The RR-952 infrared remote control serves a dual purpose. In ad-
dition to providing dedicated pushbuttons for the most needed
functions of both the RMZ-955 controller/amplifier and source
components, it also serves as a quick set-up tool during initial
configuration.
The RR-952 has a special high intensity IR transmitter. In con-
junction with the system’s sensitive receiver modules, this trans-
mitter assures reliable operation under a wide variety of
conditions.
RSM-901 Sensor/Display
The wall-mounted RSM-901 Sensor/Display receives commands
from the RR-952 hand held remote and, after processing to en-
sure maximum data integrity, sends these codes to the RMZ-955
controller/amplifier.
In addition, the RSM-901 provides continuous system status in-
formation (source, time, volume setting, etc.) at each remote lo-
cation with a dot matrix display. Also available is a
programmable alarm function.
You’ll find details of the display in the Set Up and Operation sec-
tions of this manual.
NOTE: An RSM-901 connected to the Zone A data input MUST be
used during initial set-up.
RKP-901 Keypad
The RKP-901 is a wall-mounted keypad for convenient remote
operation of the entire system. The keypad can be used as a
stand-alone control device, although it is most functional when
installed with the RSM-901 sensor-display. Its 12 key design is
the optimum balance between flexibility and simplicity, providing
single-key control of the system and source components (select-
ing and starting a CD player, for example). In addition, the
RKP-901 allows total system shut-down from a remote location. It
mounts conveniently in a standard single width wall box or in a
dual width box with a RSM-901 sensor/display. (see page 25)
RSM-901/RKP-901 Combination
Mounting both the sensor/display and keypad in one double-
width wall box carries several advantages. It simplifies the in-
stallation. It also focuses the user on one location in each zone,
i.e. walk to the keypad or aim the hand held remote control at the
same wall-plate.

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.

Cassette Deck
AM/FM Tuner
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).

Speaker Cables
Unshielded two conductor 18 gauge
(AWG) speaker wire is the minimum
acceptable standard for connections
between the RMZ-955 controller/
amplifier and zone loudspeakers. Par-
ticularly long runs may call for use of
heavier wire.
○○○○○○○○○○○○○○○○○○○○
Zone Configuration
Basic Zone Complement
Each remote zone must include at
least one control device and a pair of
loudspeakers. The control device may
be a RR-952 hand held remote and an
RSM-901 sensor/display combination.
Or it can be a RKP-901 keypad, either
stand-alone or with a RSM-901.
Remember that the RSM-901 sensor/
display also provides useful visual
clues to total system operation and ad-
ditional convenience features. Most
zones will use multiple control devices,
with the combination of one RSM-901
sensor/display, one RKP-901 keypad,
and one RR-952 being the most com-
mon.
The RSM-901 sensor/display reads in-
frared signals generated by the RR-952
hand held remote and, after translating
them into a digital code that is highly
resistant to interference, sends them
to the RMZ-955 controller/amplifier.
The RKP-901 simply translates key
pushes into digital code before send-
ing them to the controller/amplifier.
Loudspeakers
These will vary with installation
requirements and user expectations.
The RMZ-955’s amplifier sections are
optimized for impedance loads of four
ohms or higher.

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.
○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○
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.
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.
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.

Source connections
The RMZ-955 has four pair of RCA inputs for four source compo-
nents, as well as four pair of RCA “loop-through” outputs that
can send the source signals to other components.
Source inputs
Connect LINE LEVEL sources (CD player, tuner, etc.) to the
RMZ-955’s rear panel inputs as follows.
Using shielded RCA-RCA cables, connect the source’s output to
the corresponding source input on the RMZ-955. Connect analog
outputs from the source components as indicated to assure
clear operation with both the RR-952 hand held remote and the
RKP-901 keypad:
Tuner ➠ RMZ-955 Input 1
CD player
➠ RMZ-955 Input 2
Tape deck / DSS Satellite
➠ RMZ-955 Input 3
CD2 / VCR / DVD / LD
➠ RMZ-955 Input 4
Make sure to observe correct channel continuity from source to
RMZ-955. The RMZ-955’s RCA inputs are labelled for easy identi-
fication with Left Channel connections on the top row and Right
Channel connections on the bottom row.
Note 1: The RMZ-955 does not accept a phono cartridge’s output
directly. If required, use a separate phono preamp (such as
Rotel’s RQ-970BX) to boost phono signal to line level.
Note 2: Use only FIXED LEVEL source outputs to the RMZ-955.
Source outputs
Each source input on the RMZ-955 has a matching pair of “loop-
through” output RCA jacks. The primary use of these “loop-
through” outputs is to pass the signal from each source
component to additional RMZ-955 controllers in large multi-zone
systems (see page 15 for details on installing large systems).
In some cases, these “loop-through” outputs may alternatively
be used to “share” the source components with a separate
home theater or audio system. If the source is shared by another
system, connect each pair of RMZ-955 source outputs to the
appropriate inputs of the main system’s preamplifier as shown in
the hook-up illustration.
Note: The source sharing does not work with all combinations of
components. Specifically, home theater and audio systems with
micro-processor controlled source input switching may result in
problems such as interference or “mixing” between shared
sources.

Speaker Connections
The RMZ-955 is supplied with eight quick-connect screw termi-
nal plugs for speaker connections – one twin-terminal plug is
used for each speaker, two for each zone. Make the wire con-
nections from a speaker to a quick-connect plug and then insert
the plug into the appropriate receptacle on the back panel of the
RMZ-955, as illustrated.
Strip back each speaker wire’s insulation by 1/4 inch. Insert the
bare wire into one “slot” on the quick-connect plug and secure
by tightening the corresponding clamping screw. Repeat for the
other conductor, making sure that there are no loose strands of
wire which could cause a short. Repeat for the second speaker
in zone one and then continue with the other zones.
Remember to observe proper polarity when connecting all loud-
speakers. The amplifier’s “+” output should connect to the
proper speaker’s “+” terminal. “Out of phase” loudspeaker hook-
ups (where one speaker in a stereo pair is inadvertently con-
nected “+” to “-” and vice versa) may not be immediately
noticeable but will not be as pleasing as a properly connected
stereo pair. BE CAREFUL AND BE PATIENT.

The long runs from amplifier to speaker typically found in multi-
zone installations demand heavy gauge, low resistance speaker
wire. Small diameter wire reduces effective amplifier power and
adds substantial distortion to the audio signal. Avoid problems by
following these minimum recommendations:
Under 150' ➠ 18 gauge wire
150' - 300'
➠ 16 gauge wire
Loudspeaker runs over 300' are discouraged.
○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○
Preamp outputs
Two RCA jacks (Left and Right Channel) labeled “Pre-out” pro-
vide line level outputs for each of the four zones. These are pri-
marily used for systems with external power amplifiers driving
speakers in one or all of the remote zones.
Each zone’s preamp output is fully buffered and may be used ei-
ther independently or along with the RMZ-955’s internal amplifi-
ers to provide additional flexibility for demanding installations.
If a zone requires additional amplification, use standard RCA-
RCA shielded interconnects from these outputs to a separate
power amplifier’s unbalanced line inputs as shown in the hook-
up illustration on the preceding page. Connect the left channel
“Pre-out” jack to the left channel input on the power amplifier
for that zone; then repeat for the right channel connections.
Variable vs. Fixed Level
As delivered, the preamp outputs are configured to provide a
variable level output, i.e. the volume level of the signal can be
adjusted with a volume control in each zone. Alternatively, the
pre-amp outputs for one or more zones can be converted to pro-
vide a fixed level line drive signal, i.e. a signal that is always at a
fixed gain (0.25dBV below that of the source component). This
may be useful in certain custom applications.
Converting the pre-amp outputs to fixed level operation requires
removing the top cover of the RMZ-955 and locating the four
“line driver” plug-in modules. Looking from the front of the unit,
these are small vertical circuit boards located in front of the heat
sink. They are labeled Zone A through Zone D, from left to right.
Notice that the modules are printed circuit boards that plug into
the main board. Each module has two rows of “pins”, one on the
bottom (which is plugged into a socket as delivered from the fac-
tory) and the other pointing up. To reconfigure from variable level
pre-amp outputs to fixed level pre-amp outputs, simply remove
the module from the socket on the main circuit board, rotate it
180 degrees, and reinsert it in the same socket using the row of
pins on the opposite end.

less of which set of header pins you use. Also note that the pins
and the socket are labeled 1 — 15. Pin 1 is always inserted into
Socket 1, etc.
Note You can configure each of the four zones independently, by
rotating just its module. Some zones can be configured as vari-
able outputs, while others are reconfigured as fixed outputs by
reorienting some or all of the modules.

Data cable connections
Data communication to and from the RMZ-955 controller and the
remote zones’ RSM-901 sensor/displays and RKP-901 keypads is
by 6 conductor shielded cable.
Note: One, and only one, data cable runs from the RMZ-955 to
each zone. Multiple sensor/display and keypad combinations in
one zone should be wired via series connections detailed in the
section on Zone Connection Strategies (page 15).
We recommend the use of Belden 9536 cable or the equivalent.
The Methode data connectors supplied with the RMZ-955 only
accept cable with 24 gauge conductors.
Using cable with a foil and/or braided shield is absolutely essen-
tial in maintaining data integrity over the long runs between the
controller/amplifier and a zone’s control code generating de-
vices. Make sure that the shield is firmly connected at both the
RMZ-955 and at any command device terminal.
We recommend that you run each zone’s data cable and speaker
cables together to save time. There is absolutely no performance
penalty for doing so.
PROPER DATA CABLE TERMINATION IS CRITICAL. All connec-
tions for RMZ-955 and the remote zone’s RSM-901 sensor/dis-
plays and RKP-901 keypads use the color code shown in the
following illustration:
DATA CONNECTOR
WIRING CODE
Pin 1• black & shield
Pin 2• white
Pin 3• red
Pin 4• brown
Pin 5• blue
Pin 6• green
Connections are made
in the same order at
both ends of the cables.
1 2 3 4 5 6
The supplied Methode connectors need to be crimped to lock to
the data cable’s 24 gauge conductors.
Note: Do not use a screwdriver, metal ruler or knife blade to
“crimp” these connections. You may think these tools will work
but you will be mistaken. USE THE DEDICATED CRIMPING TOOL
SPECIFICALLY DESIGNED FOR THESE CONNECTORS. This tool is
available from Rotel.
• Strip about 1.5" of the outer cable insulation using a sharp knife.
Separate the outer shield from the conductors and trim it off
flush with the outer insulation, being careful not to trim off the
shield or “drain” wire.
• DO NOT strip insulation off the six individual conductors as the
connector automatically makes contact with the conductor core
when crimped.
• Place the shield or “drain” wire into slot 1 of the connector.
Then, place the BLACK conductor immediately on top of the
drain wire in slot 1, hold them both in place and push the crimp-
ing tool handle until you hear a slight “click.” Both conductors
should now be locked into slot 1. The rachet action of the crimp-
ing tool ensures proper connection. The clicking sound tells you
that the connector slot contacts have pierced the conductor’s
insulation.
• Continue the process following the color code guide above until
all other conductors are locked in the appropriate connector
slots. Remember that slot 1 is the ONLY ONE to get the drain
wire and a conductor. All other slots receive only a conductor.
After attaching the cable conductors to the connector, insert it
into the appropriate zone’s 6 pin data terminal on the RMZ-955’s
rear panel. Be careful to center the connector over the terminal
pins before inserting.
The maximum cable length for guaranteed operation is 300'.
Longer lengths may be practical in some installations with low
RF (radio frequency) and EMI (Electro-Magnetic Interference).

Infrared Control System
The RMZ-955’s IR system provides extensive control flexibility
accepting remote control codes generated by keypads and/or
hand-held remotes, relaying them to the system controller, and
passing them along to the source components via a front-panel
flood emitter or individual remote IR emitters plugged into the
rear panel. However, please note the following points:
The IR codes generated by the RR-952 hand held remote are
RMZ-955 “system specific” codes and ARE NOT the same codes
generated by a source component’s own controller, even for
functions that appear identical such as “CD play,” for example.
In other words, you can not use the RR-952 to directly control a
Rotel CD player but must use it through an RSM-901 sensor/dis-
play from a remote zone.
The RMZ-955 IR control system does the following:
• An RSM-901 sensor/display receives the remote’s code se-
quence and translates it into proprietary 5 bit digital code.
• This digital code travels over the data cable to the RMZ-955
controller/amplifier.
• The RMZ-955’s translator card restores the code’s original con-
figuration (when required) and sends it to both the IR flood emit-
ter and the rear panel IR outputs for use by the appropriate
source component.
In addition to passing RMZ-955 system codes, the IR system will
pass ALMOST any IR code sequence from an RSM-901 to a
source component. (These few exceptions use a non-standard
IR transmission frequency.) This allows you to control transport
functions of a VCR from a remote zone, for example, with the
VCR’s dedicated hand held remote.
Front Panel IR Flood Emitter
The RMZ-955 features a front-panel flood emitter for sending IR
codes to the source components own front-panel IR sensors.
Note: It is essential that the output of the front-panel flood emit-
ter NOT be allowed to reach an RSM-901 sensor/display. This
could result in an IR loop and unstable system operation includ-
ing “lock-up”
RMZ-955s are shipped with the front panel IR flood emitter en-
gaged. However, there may be applications (system installations
on open shelves in very large, bright rooms, for example) where
the IR flood emitter might interfere with proper source compo-
nent operation or will not be particularly effective in communi-
cating control pulses. Or, there may be systems where an
RSM-901 display/sensor located in the same room as the RMZ-
955. In these cases, disable the front-panel flood emitter and use
individual IR emitters connected the RMZ-955’s rear panel and
placed over each source components IR sensor.
To disable the IR flood emitter, remove the jumper wire between
screws 2 and 3 of the TX FORMAT terminal block located on the
lower right hand side of the RMZ-955’s rear panel.

IR flood emitter. One required
for each source component.
NOTE: There is a very low intensity red LED mounted behind the
emitter’s window which flashes whenever it is transmitting IR
codes. Use this LED to verify the emitter’s operating status.
Rear Panel IR Repeaters
In many system configurations, the most reliable, trouble-free
means of passing IR control codes to the source components is
with individual IR emitters, one for each source. Use these op-
tional repeaters in situations where the RMZ-955 will be located
some distance away from the source components or where the
IR flood emitter may have difficulty transmitting reliable source
control data. Disable the flood emitter when using the optional IR
remote emitters.
The RMZ-955 rear panel has four paralleled 3.5mm mini-plug
sockets labeled “TX OUTPUTS.” They accept standard “stick on”
IR emitter like Xantech’s Video Link 282-00. Plug a repeater into
one of the sockets and place it over the source component’s IR
sensor. Repeat for the other three sources.
Note: Some source components, such as some Rotel sources, al-
low a direct connection from a 3.5 mm rear panel IR emitter con-
nection to a matching 3.5 mm connection on the source
component, eliminating the need for stick-on IR emitters.

Paging Input
The paging input allows announcements to be made over the
system, and, if required, for Zones to be momentarily muted, in
conjunction with a doorbell or a phone system.
The paging feature needs to be activated from an external
source via the “paging trigger” RCA-type input jack on the back
of the RMZ-955. Any device which shorts the trigger input will
cause the controller to enter its paging mode. For example, a
doorbell, a phone system , or a keyed announcement micro-
phone system could provide this control.
The “Paging Audio In” RCA jack is connected to the audio output
of the announcement system (phone or microphone amplifier).
The “Paging Audio Output” jack can be connected to the Paging
Audio Input on a second controller (in a large multi-controller
system) or to the RCA input of an external amplifier.

RSM-901 Mounting
The RSM-901 Sensor/Display mounts in a single-width wall box
or in a double width box with the RKP-901 keypad.
PLACEMENT SUGGESTIONS: Exact placement will vary with
each installation but we strongly recommend AGAINST place-
ment where the RSM-901 will be exposed to direct sunlight, pow-
erful fluorescent illumination or the output of a high intensity
spotlight, etc. These light sources contain high levels of infrared
energy themselves and may cause intermittent operation by
saturating the RSM-901.
Note: Avoid infrared “loops” by making sure that an RSM-901
sensor/display is not placed where it might pick up signals from
a source component’s IR repeater or the RMZ-955’s IR front
panel flood emitter.
Lastly, make sure that each RSM-901 is on a relatively uninter-
rupted “line-of-sight” path to all likely locations from which the
hand held RR-952 remote might be used. You’ll find the RSM-901/
RR-952 combination much less susceptible to signal interference
than other IR remote control links, but planning will ensure de-
pendable operation under an even wider variety of conditions.

Note that each RSM-901 has two data terminals labeled “In” and
“Out” respectively. Connect the remote zone end of the data
cable from the RMZ-955 to the “Out” connector on the RSM-901.
The “In” connector is used to “daisy-chain” additional RSM-901
display/sensors or RKP-901 keypads in the same zone. See
Zone
Connection Strategies
on page 15 for details.
A number of configuration settings must be made using the
switches and jumpers on the back of the RSM-901. These are de-
tailed below.
Battery Enable
Each RSM-901 has a rechargeable back-up battery which main-
tains the clock and configuration information when power to the
controller is switched off. When fully charged, the battery will
then maintain the configuration information for several weeks.
The battery must be enabled when the RSM-901 is installed. To
enable the battery, place the jumper JP1 to link the two pins as
shown in the illustration above.
Note: After initial installation, leave the RMZ-955 turned on con-
tinuously for a few days to ensure that the battery is charged.
Zone Configuration
Each RSM-901 must be configured or “addressed” as being in
Zone A, Zone B, Zone C, or Zone D. You select the proper zone by
setting Switches 1 & 2 on the DIP switch shown in the illustra-
tion. Use the following settings:
Zone Switch 1 Switch 2
A (default) OFF OFF
B OFF ON
C ON OFF
DONON
Source Component Labels
Each RSM-901 must be configured to display the correct label for
each source component. It always displays “Tuner” for source
input 1 and “CD” for source input 2. However, source input 3 can
display “Tape” or “Sat” depending on the setting of Switch 3 and
source input 4 can display “CD2”, “VCR”, “Ld”, or “DVD” de-
pending on the setting of Switch 4 and Switch 5. Use the follow-
ing settings:
Source Input 3 Switch 3
Tape (default) OFF
Sat ON
Source Input 4 Switch 4 Switch 5
CD2 ON ON
VCR ON OFF
LD OFF ON
DVD (default) OFF OFF
Note: Remember to set these switches on all RSM-901s.
Master/Slave Configuration
Each RSM-901 must be configured as a Master or Slave by set-
ting Switch 6. Because it is possible to have more than one
RSM-901 in any zone, follow the simple rules to ensure that the
required functions are available:
Each zone used in a system must have a Master RSM-901. In a
zone with more than one RSM-901, only one must be set as a
Master and each other must be set as a Slave. The Master must

System Reset
After changing any of the above configurations, reset the
RSM-901 by pressing the RESET switch (SW1). This is essential
to allow the new setting to take effect.
Source Component Set-up
After installation, refer to System Set-up and Programming (page
21)
for configuring the proper data codes for source component
operation.
Remember that an RSM-901 connected to the Zone A data cable
terminal MUST be used for initial set-up, particularly in systems
where non-Rotel source components are included.
Note: After completing the installation and component set-up,
power down the system, wait approximately 30 seconds, and
then power it up again. Test all functions.

RKP-901 Mounting
The RKP-901 keypad mounts in a wall box in the same manner as
the RSM-901 sensor/display. There are no restrictions on where
the RKP-901 can be located. Common sense and user conve-
nience should be the determining factors. Alternatively, the
RKP-901 can be mounted in a double-width wall box with an
RSM-901 sensor/display. This is the most sensible arrangement
from an installation viewpoint (fewer cable runs) but may not be
practical in all rooms.

RKP-901 Data Connections
RKP-901s do not need to be set for particular zones or configured
as Master/Slaves because they do not display zone or system
status information.
Data cable terminations and connections are made the same
way as previously detailed. As does the RSM-901, each RKP-901
has two data terminals (“In” and “Out”) located at the bottom of
its circuit board. Connect the “Out” terminal, either to the “In”
terminal of an RSM-901 in the zone, or to the RMZ-955 controller
if the zone does not have a RSM-901.

Zone Connection Strategies
Each zone will support up to three RSM-901s and three
RKP-901s. All of the command devices for one zone should con-
nect to each other in serial fashion using their appropriate cir-
cuit board-mounted “In” and “Out” terminals.
Each RSM-901 signals when it receives and processes a com-
mand. This happens regardless of whether the command was
generated by a keypad or a hand held remote. However, a key-
pad located “downstream” of a sensor/display will
not trigger
that sensor’s command processing indicator.
Whenever possible, we suggest that you configure each zone so
that all keypads are “upstream” from all sensor/displays. Al-
though not always practical depending on the zone configura-
tion, this arrangement will reduce user confusion.
Regardless of other considerations, we suggest that you always
wire an RSM/RKP double wall box so that the RSM is located
“downstream” from adjacent RKP (i.e., between the RKP and the
RMZ-955 controller/amplifier). This assures that the sensor/dis-
play always signals the user when the adjacent keypad is used.
Installation is the first step towards enjoying an RMZ-955 system.
Proper set-up ensures that the RMZ-955 will function optimally
with all associated source components and provide total system
control.
Installation: Multi-controller Systems
Each RMZ-955 provides independently controlled audio distribu-
tion from four sources to four separate zones. To satisfy the re-
quirements of more elaborate systems, up to four RMZ-955s can
be cascaded to build a system with as many as 16 independent
zones. Under these circumstances, all RMZ-955 controller/ampli-
fiers share one set of four source components.
When system complexity calls for more than one RMZ-955, we
have no cautions about stacking controller/amplifiers on top of
each other. As long as there is sufficient room to allow relatively
unrestricted air flow, heat should not be a problem.
In most respects, installing a multi-controller system is no differ-
ent than a single controller system. Source input connections,
speaker output connections, data cable connections to the re-
mote zones, and other configuration steps are essentially the
same. Review
Installation: RMZ-955 Controller (page 5) for com-
plete information.
There are, however, some additional considerations and installa-
tion steps required for a system with multiple RMZ-955 control-
lers. These steps all deal with the need to link the controllers:
a) AC connections for fully-integrated system control
b) Sharing four sources among all controllers
c) Passing IR commands from one controller to the rest
d) Linking special features like system-wide paging
All hookup instructions in this section assume that Zones 1-4
will be handled by the first RMZ-955 (called “A”), Zones 5-8 by
the RMZ-955 immediately above it (“B”), Zones 9-12 by third
unit (“C”), and Zones 13-16 by the top unit (“D”). In most cases,
we do not illustrate all four controllers, as additional controllers
are merely added in the same fashion as the second or third con-
troller.
There is no functional distinction between the first RMZ-955 and
additional controllers in a system. However, for convenience and
simplicity, we assume that the first controller will handle some
additional responsibilities, such as source inputs and sending IR
signals to the sources. This approach makes it easy on the in-
staller, particularly when starting with a single RMZ-955 and later
expanding with additional controllers. Essentially, the work done
installing a single RMZ-955 remains unchanged and additional
zones are handled by “add-on” RMZ-955 controllers.

AC Power
Multiple controller systems require handling AC connections in a
way that allows any zone to “power up” or “power down” the
system. In other words, there must be a provision for zones con-
nected to additional RMZ-955 controllers to control the system’s
switched AC outlets.
A special feature of the RMZ-955, called “AC Link” simplifies the
installation of multi-controller systems with a simple control line
connection between units for AC control.
AC Connections
Plug all RMZ-955 controllers into unswitched AC outlets, provid-
ing a constant AC supply.
Plug all source components into the switched outlets located on
the rear panels of the RMZ-955 controllers. As in a single-con-
troller system, the recommended approach is to use a Rotel RLC-
900 power conditioner/switcher in conjunction with the first
RMZ-955’s rear panel outlets. This allows the first RMZ-955 to
handle all AC switching for the system.
With the “AC Linking” feature, it is also possible to plug source
components into any switched outlet on the rear panel of any
RMZ-955. All of these outlets are controlled in unison. When the
system is “powered up” from any zone, the switched outlets on
the first RMZ-955 and all other controllers are turned on. When a
“power down” command is sent, all RMZ-955’s go into standby
and their rear panel switched outlets are turned off.
AC Link
Unified AC control in multi-controller systems is achieved by a
special “AC Link” connection from the first RMZ-955 to the sec-
ond and so on down the line. This connection uses standard 3.5
mm stereo mini-jacks at both ends of a 3-conductor cable.
Note: It is essential to use a stereo mini-jack for the “AC Link”
connection between controllers (such as Radio Shack #274-389).
Do not substitute a mono 2-conductor cable.
To make the connection, plug one end of the 3.5 mm stereo cable
into the 3.5 mm jack labeled “Link Out” on the first RMZ-955.
Then plug the other end of the cable into the jack labeled “Link
In” on the second RMZ-955. Then link the second RMZ-955 by
connecting its “Link Out” to the third RMZ-955’s “Link In” jack
with another cable. And, so on until there is an “AC Link” con-
nection between all RMZ-955 controllers.
External 5V Trigger: Once you have completed all of the “AC
Link” connections, the “Link Out” connector on the last RMZ-955
is still available. This jack can provide a +5V D.C. control voltage
that could be used to activate external devices in an elaborate
custom system. When the Rotel system is activated from any
zone, this control signal goes to +5V. When the total system
“power down” command is given from any zone, the RMZ-955
controllers go into Standby mode, the rear panel switched AC
outlets are shut off, and this control signal goes to 0V.
This external trigger requires the same 3.5 mm stereo mini-jack
as the “AC Link” connections. The “tip” of the connector carries
the +5V DC control voltage.
Manual AC Override
There is a provision to manually override the “AC Link” control of
the switched outlets. While not common, there may be custom
system configurations where being able to manually power up all
of the switched outlets and components connected to them.
To enable the manual override, connect Pin 1 and Pin 6 of the
rear panel TX FORMAT jumper block with a jumper wire. As long
as these two pins are connected, the switched AC outlets on all
RMZ-955’s will be powered on. When the two pins are uncon-
nected, control of the AC outlets will revert to standard control
from the zones, depending on whether the system has been acti-
vated from a zone or not.
In practice, the manual override jumper described above would
be replaced with a simple single-pole switch connected be-
tween Pin 1 and Pin 6 of the “TX-FORM” block. When the switch
is closed, manual override is active. When the switch is open,
activation of the AC outlets reverts to standard zone control.
To manually turn on all
switched AC outlets, connect
pins 1 & 6 with a jumper
or closed switch

For automatic system
control of switched AC
outlets, remove jumper
or open switch
TX-FORMAT
123456
Note: In multi-controller systems, Pin 6 must be connected from
the first controller to the Pin 6 on the next, and so on daisy-
chainging all RMZ-955s to enable the manual override.

Source Connections
Multi-controller systems share the same four source compo-
nents. Therefore, it is necessary to pass the signal from each
source to all of the RMZ-955 controllers in a system.
Connect all sources to the first RMZ-955 per the instructions as
shown
