In addition to installation and operating instructions, it provides valuable information on various

24、 RDA-986 system configurations as well as general information that will help you get optimum performance from your system. Please contact your authorized Rotel retailer for answers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments. Save the RDA-986

25、shipping carton and all enclosed packing mate- rial for future use. Shipping or moving the RDA-986 in anything other than the original packing material may result in severe dam- age that is not covered by the warranty. Be sure to keep the origi- nal sales receipt. It is your best record of the date

26、of purchase, which you will need in the event warranty service is required. Placement Use common sense when placing the RDA-986 in a cabinet or when stacking other equipment. Make sure that the shelf or cabi- net can support its weight. Do not stack heavy components on top of the RDA-986. Avoid plac

27、ing the unit where it may be subject to excessive heat such as on top of a large power amplifier or near a heat register. For best performance, avoid placing the unit where it may be subject to vibration, such as near a speaker. AC Power and Control AC Power Input 12 Your RDA-986 is configured for t

28、he proper AC voltage in the coun- try where you purchased it (either 115 volts or 230/240 volts). The AC line configuration is noted on a decal on the back panel. Note: Should you move your unit to another country, it may be possible to reconfigure it for use on a different line voltage. Do not atte

29、mpt to perform this conversion yourself. Opening the enclo- sure of the RDA-986 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information. The RDA-986 should be plugged directly into a 2-pin polarized wall outlet or into the switche

30、d outlet on another component in your audio system. Do not use an extension cord. Be sure the power switch on the front panel of the RDA-986 is turned off. Then, connect the supplied power cord to the AC power receptacle on the rear of the unit and the AC power outlet. If you are going to be away fr

31、om home for an extended period of time such as a month-long vacation, it is a sensible precaution to unplug your RDA-986 (as well as other audio and video compo- nents) while you are away.

33、_ 5 Getting Started Thank you for purchasing the Rotel RDA-986 DTS Surround Adaptor. The RDA-986 is a high-quality outboard digital processor for decoding discrete DTS 5.1 channel surround sound encoded Laser Discs and Digital Video Discs. The RDA-986 accepts an en- coded DTS digital signal, decodes

34、 it, and sends six discrete ana- log surround sound audio signals to the 5.1 channel input on a surround sound processor or other system controller. With its pre- mium components, Balanced Design, and robust construction, the RDA-986 will provide years of enjoyment in your system. The RDA-986 is sim

35、ple to operate. Other than a power switch, there are no front panel controls or switches. The unit senses when a DTS signal is present and engages the decoding circuitry automatically. The RDA-986 also provides pass-through digital outputs and ana- log inputs to provide full flexibility in a number

36、of system configu- rations. For example, a second outboard decoder (such as Dolby Digital) can be connected to the analog inputs of the RDA-986. When a DTS signal is present at the digital input, the RDA-986 will decode it and send the signal to the outputs. When no DTS signal is present, the RDA-98

37、6 will pass the signal from the analog inputs to the outputs. 3 DTS SURROUND ADAPTOR RDA-986 Power Switch 1 and Power Indicator 2 The power switch is located on the front panel of your RDA-986 Surround Adaptor. To turn the unit on, push the switch in. The LED indicator above the switch will light, i

38、ndicating that the unit is turned on. To turn the RDA-986 off, push the button again and re- turn it to the out position. Digital Signal Connections The RDA-986 features two standard digital inputs (optical or co- axial) which receive a digital data stream from a DTS-compatible LaserDisc or DVD play

39、er. In addition, a pass-through digital output connector (coaxial) can be used to send the raw digital data stream to another processor, such as a Dolby Digital decoder. Digital Inputs 5 and 7 The RDA-986s digital inputs accept a digital signal from your LaserDisc or DVD player. Two types of digital

40、 inputs are available an optical input connection and a 75 ohm coaxial input connec- tion. Select the type of connection that best matches the output connector on your video disc player or other source component, using either a standard optical digital cable or a standard 75 ohm coax digital cable.

41、Digital Input Selector Switch 6 A two-position switch located between the digital inputs selects the appropriate digital input connector, either optical or coax. If you connect your video disc player to the RDA-986s optical input, place this switch in the left position (labeled OPTI). If you use the

42、 coax input, slide this switch to the right position (labeled COAX). Coaxial Digital Output 8 The digital output connector is used to pass the unprocessed digi- tal signal from the digital input through to another processor. For example, the same DVD player might be used to play both DTS en- coded a

43、nd Dolby Digital encoded surround sound material. A DTS encoded signal will be decoded by the RDA-986 and the resulting 5.1 channel analog signal sent to the surround sound processor. A Dolby Digital encoded signal will be sent, unprocessed, from the digital output to the digital input of a Dolby Di

44、gital decoder for pro- cessing. This pass-through feature allows you to use the RDA-986 with an outboard Dolby Digital decoder or with a surround sound processor that includes built-in Dolby Digital decoding. Connect the digital output connector to the digital input connector on your Dolby Digital d

45、ecoder or directly to your surround sound processors digital input, if it has built-in Dolby Digital decoding. DTS Indicator 3 and Signal Indicator 4 There are two LED indicators on the RDA-986 front panel which indicate whether a signal is present at the digital input. The SIG- NAL indicator lights

46、 whenever a digital signal from a source com- ponent is sensed by the digital inputs. The DTS indicator lights if that digital signal is DTS encoded. Analog Signal Connections The RDA-986 has 5.1 channel analog output connections for send- ing decoded DTS information (six discrete channels: left fro

47、nt, right front, center, left rear, right rear, and subwoofer) to the sur- round processor or system controller. In addition, the RDA-986 features a 5.1 channel analog pass-through input, which can be used to accept a decoded 5.1 channel signal from another out- board decoder, such as Dolby Digital,

48、 to the surround processor, thus simplifying connections in an elaborate system. 25-pin Analog Output 10 The most convenient analog output connection is the rear panel 25-pin connector. This is a standard DB-25 connector which car- ries all six channels of decoded analog signal in a single cable. If

49、 you are using a surround processor which has a matching DB-25 input, such as all Rotel surround processors, this will provide a convenient, simplified output connection. Simply connect the out- put to the matching 5.1 channel input on your surround processor using a standard female-to-male DB-25 audio connector. RCA Analog Outputs 11 The RDA-986 also provides six RCA output connectors for use with surround sound p
