Rear Panel: Digital Inputs 40
The RSX-965 features a complete D/A conversion capability which accepts digital input signals from source components such as CD players, satellite TV receivers, and 5.1 channel Dolby Digital or DTS signals from DVD and Laser Disc players. The D/A automati- cally senses and adjusts to the correct sampling rates.
These digital inputs are available for VIDEO 2 (coaxial), VIDEO 3 (coaxial), VIDEO 4 (optical), and AUX/VIDEO 5 (optical).
To use the digital inputs, connect the appropriate cable (optical or coaxial) from the digital output of your source component to the corresponding DIGITAL INPUT on the RSX-965. Make sure that if you have connected the analog signals from a source to VIDEO 2, that you also connect its digital output to VIDEO 2, etc.
Even when using digital connections, you should still make the analog input connections described above. The analog connec- tion is necessary should you wish to record from that source com- ponent to an audio tape deck or VCR.
5.1 Channel Audio Input 39
This female DB25 25-pin input connects six discrete channels of analog information from an outboard processor in a single cable.
Many external adaptors provide a choice of RCA or DB25 outputs. We suggest that you use a DB25-to-DB25 cable to reduce the number of cables and to insure proper channel-to-channel conti- nuity. If your external adaptor does not have a DB25 output, you will need to purchase a multi-RCA to DB25 adaptor cable from your authorized Rotel dealer. Make sure to observe proper chan- nel continuity. See Figure 4 for DB25 pin assignments.
Speaker Outputs 43
The RSX-965 has five built-in amplifiers, two for the front (right and left), one for the center channel, and two for the rear sur- round speakers (right and left). On the back panel are five pairs of binding posts, one pair for each speaker, which accept bare wire, connector lugs, or banana type plug connectors (except in the Eu- ropean Community countries where their use is not permitted).
Each pair of connectors is color-coded for polarity: red for the positive connection and black for the negative connection. All speakers and all speaker wire is also marked for polarity. It is es- sential for proper performance to maintain this polarity at all speaker connections. Always connect the positive terminal of each speaker to the corresponding red speaker terminal on the RSX-965 and the negative speaker terminal to the corresponding black connector on the RSX-965.
Each pair of connectors is also clearly labeled as FRONT LEFT, FRONT RIGHT, REAR LEFT, REAR RIGHT, or CENTER. It is equally essential that you connect the each of the five speakers to the proper terminal on the RSX-965.
Route the wires from the RSX-965 to the speakers. Give yourself enough slack so you can move the components to allow access to the speaker connectors. If you are using banana plugs, connect them to the wires and then plug into the backs of the binding posts. The collars of the binding posts should be screwed in all the way (clockwise). If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip back the insulation from the end of each conductor. Be careful not to cut into the wire strands. Unscrew (turn counterclockwise) the binding post col- lars. Place the connector lug around the binding post shaft, or in- sert the bundled wire into the hole in the shaft. Turn the collars clockwise to clamp the connector lug or wire firmly in place.
Note: Be sure there are no loose wire strands that could touch adjacent wires or connectors.
