22、e RSS-900 answers the dilemma faced by many audiophiles who want the flexibility and convenience of a multi-speaker, multi- room system without having to sacrifice sound quality. The RSS-900 provides a switchable set of “Direct” speaker connec- tions to ensure the speakers in the primary listening l

23、ocation re- ceive an unaltered signal. In addition five other switchable sets of connections are provided. These outputs have impedance com- pensation that allows any combination of speakers, or all the speakers, to be switched on. These outputs also have inductor coils connected to them to countera

24、ct the effects of excess ca- pacitance that can result from long, multiple runs of speaker wires. This additional circuitry ensures that your amplifier will produce the best possible sound, regardless of which speakers are switched on. The RSS-900 is straightforward in its installation and operation

25、. If you have experience with other stereo systems, you shouldnt find anything perplexing. Simply connect the associated components and enjoy. A Few Precautions Please read this manual carefully. It provides complete informa- tion on how to connect the RSS-900. Please contact your autho- rized Rotel

26、 dealer for answers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments. Save the RSS-900 shipping carton and all enclosed packing mate- rial for future use. Shipping or moving the RSS-900 in anything other than the original packing material may resul

27、t in severe damage. Fill out and send in the owners registration card packed with the RSS-900. Also be sure to keep the original sales receipt. It is your best record of the date of purchase, which you will need in the event warranty service is ever required. Note: The RSS-900 does not require AC po

28、wer to operate. DO NOT attempt to connect it to the AC mains supply! 6 SPEAKER SELECTOR RSS-900 Associated Components The RSS-900 is designed for use with amplifiers that can produce as much as 200 watts per channel. (See the information in the fol- lowing section regarding ventilation.) The amplifi

29、er should be ca- pable of handling 4 ohm impedance loads. NOTE: If speakers that have a minimum impedance of less than 4 ohms are connected to the RSS-900 the impedance the amplifiers receives may be less than 4 ohms. Check the instruction manual for your speakers for this information. If you are un

30、sure about whether or not a certain combination of speakers can safely be used with the RSS-900 and your amplifier consult your authorized Rotel dealer. Placement Place the RSS-900 on a firm flat surface where it will be free from excessive dust, heat or cold, moisture or high humidity, or expo- sur

31、e to direct sunlight. Do not allow any foreign objects to fall into the ventilation holes of the RSS-900. Like many audio components that handle high-level signals, the RSS-900 produces some heat during normal operation. Do not place anything on top of the RSS-900 or allow the vent holes in the top

32、of the cabinet to be blocked. There should be at least 3” (75mm) of room above the RSS-900 to allow for heat dissipation. Cables Because as many as 6 pairs of speakers may be connected to the outputs of the RSS-900, the wires from the amplifier output to RSS-900 input should be heavy gauge (12 AWG)

33、speaker wire. Slightly lighter gauge wire may be used to connect the RSS-900 to the speakers. High quality, high performance wire will frequently improve the sound of a system. Consult your authorized Rotel dealer for advice about the best wires to use with your system. Connection Note: Turn off the

34、 power to all the components in the system be- fore you make any signal connections. Polarity/Phasing and Proper Channel Connection The polarity the positive/negative orientation for every con- nection between the amplifier and the RSS-900, and between the RSS-900 and the speakers, must be consisten

35、t so all the speakers will be in phase. If the polarity of one connection is mistakenly re- versed, bass output will be very weak and stereo imaging de- graded. All wire is marked so you can identify the two conductors. There may be ribs or a stripe on the insulation of one conductor. The wire may h

36、ave clear insulation with different color conduc- tors (copper and silver). There may be polarity indications printed on the insulation. Identify the positive and negative conductors and be consistent with every connection. Note: All speaker wire consists of many small strands of wire. When making c

37、onnections to the terminals of the amplifier, the RSS-900, or the speakers, twist these strands into a tight bundle and secure all the wires in the terminal. There must not be any loose strands of wire from one terminal that could touch the other. This will cause a short circuit. It is also very imp

38、ortant to be sure that the left and right channels do not get reversed. Work carefully and be sure that the proper channels are connected at every amplifier, RSS-900 and speaker connection point. Input From Amplifier 3 (See the connection diagram Figure 2) Use heavy duty speaker wires to connect the

39、 output of the ampli- fier to the input of the RSS-900 as shown. Direct Speaker Output Connection 4 Connect the speakers in your primary listening location to the out- put terminals labeled “Direct”. These outputs do not have the im- pedance matching and capacitance control components that the other

40、 outputs (1-5) have. This provides you with the convenience of being able to turn the main speakers in your system on and off, while ensuring that the signal to them is not affected by extra cir- cuitry. Speaker Output Connections 1 5 5 Connect the secondary speakers in your system to the outputs la

41、- beled 1 through 5. These outputs have impedance matching and capacitance control components that allow the amplifier to safely drive any combination of speakers. 7 Speaker On/Off Switches See Figure 1 for switch identification. Direct Speaker Switch 1 This switch turn on and off the speakers conne

42、cted to the Direct outputs. Push in the top of the rocker switch to turn the speaker on. Push in the bottom of the rocker switch to turn the speaker off. Speaker Output 1 5 Switches 2 These switches turn on and off the speakers connected to the corresponding outputs. Push in the top of the rocker sw

43、itch to turn on the speaker connected to that output. Push in the bottom of the rocker switch to turn off the speaker connected to the output. English Troubleshooting Most difficulties in audio systems are the result of incorrect con- nections, or improper control settings. The RSS-900 is a passive

44、device with no power supply or components that are likely to fail. If you encounter problems, it is probably the result of another component in the system. If the problem does involve the RSS-900 it is probably a matter of improper connections. No Sound If one or both channels is not producing sound

45、, check to see if other speaker outputs are functioning properly. If the problem is isolated to one set of speakers it is probably the result of improper connections to the RSS-900 or the speakers. If all the speaker sets in the system are experiencing the same problem check another signal source. I

46、f neither channel is pro- ducing sound check the tape monitor switches on the preamplifier (or integrated amplifier, or receiver) to be sure they are properly set. If the problem persists check the connections between the preamp and power amp (if appropriate) and the connections be- tween the speake

47、r outputs and the RSS-900 inputs. Be sure there are no loose strands of wire causing a short circuit between the connection terminals at either the amplifier outputs or the RSS- 900 inputs. Distorted Sound There is almost nothing that involves the RSS-900 that could pro- duce distorted sound. Such p

48、roblems are almost certainly the re- sult of problems elsewhere in the system. In rare instances a loose strand of speaker wire that is barely touching the other wire or terminal can cause an intermittent crackling noise. This is easy to check and eliminate as a possible source of the problem. 082 O
