1、1 RMZ-955 MULTI-ROOM SYSTEM Installation 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,

2、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 operati

3、on 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 ar

4、e 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 t

5、he 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.

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

INSTALLATION: RMZ-955 CONTROLLER MULTI-ROOM SYSTEM CONTROLLER RMZ-955 12 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: O

9、ne, 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 Method

10、e 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 zones control code generating de- vices. Make sure t

11、hat the shield is firmly connected at both the RMZ-955 and at any command device terminal. We recommend that you run each zones 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 f

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 SPECI

14、FICALLY 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

15、 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 plac

16、e 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 conductors insulation. Continue

17、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, inse

The maximum cable length for guaranteed operation is 300. Longer lengths may be practical in some installations with low RF (radio frequency) a

19、nd EMI (Electro-Magnetic Interference). 13 Infrared Control System The RMZ-955s 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

20、 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 components own controller, ev

21、en 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

22、receives the remotes 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-955s translator card restores the codes original con- figuration (when required) and sends it to both the IR flood em

23、it- 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

24、you to control transport functions of a VCR from a remote zone, for example, with the VCRs 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 th

25、e 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 installa

26、tions 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 ro

27、om as the RMZ- 955. In these cases, disable the front-panel flood emitter and use individual IR emitters connected the RMZ-955s 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

28、located on the lower right hand side of the RMZ-955s rear panel.

Use this LED to verify the emitters operating status. Rear Panel IR Repeaters In many system configurations, the mos

31、t 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

32、 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 Xantechs Video Link 282-00. Plug a rep

33、eater into one of the sockets and place it over the source components 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 co

34、mponent, eliminating the need for stick-on IR emitters. INSTALLATION: RMZ-955 CONTROLLER MULTI-ROOM SYSTEM CONTROLLER RMZ-955 14 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 pho

35、ne 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 anno

36、uncement 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-cont

37、roller system) or to the RCA input of an external amplifier.

39、Each Zone has an internal micro switch which is used to set the paging function ON/OFF for that zone. These switches are accessed by removing the top cover of the RMZ-955 by a qualified technician. Make sure that the AC power line is disconnected before removing the cover. ZONE AZONE BZONE CZONE D P

42、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 o

43、f 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 sour

44、ce components IR repeater or the RMZ-955s 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. Youll find the RSM-901/ RR-952 combination much less susce

45、ptible to signal interference than other IR remote control links, but planning will ensure de- pendable operation under an even wider variety of conditions.
