Input Signal Connections

The RA-932 has conventional RCA type input connectors, the type found on nearly all audio equipment.

Note: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections.

Phono Input 11 and Ground Wire Connection 10

[See Figure 3 for phono input connection illustration.]

Plug the cable from the turntable into the appropriate left and right phono inputs. Most turntables also have a “ground” wire. Connect it to the screw terminal to the left of the Phono inputs. It will help prevent hum and noise.

Line Level Inputs 12

[See Figure 2 for line level input connection illustration.]

The CD, Tuner, and Aux inputs of the RA-932 are all “line level” in- puts. These are for connecting components such as CD players, Hi Fi or NICAM Stereo video cassette recorders, tuners for audio or video, Laser Disc players or the analog output from a CD ROM drive. Figure 2 shows a CD player connected to the CD inputs. Other components are connected in the same way.

The Left and Right channels are clearly labeled and should be connected to the corresponding channels of the source compo- nent. The Left RCA connectors are white, the Right connectors are red. Use high quality RCA cables for connecting input source components to the RA-932. Ask your authorized Rotel dealer for advice about cables.

Recorder Connections 13

[See Figure 2 for recorder connection illustration.]

The Tape inputs and outputs can be connected to any record/ playback device that accepts standard line level analog input and output signals. Typically that will be a conventional tape recorder.

When connecting a recorder to the RA-932 remember that the outputs of the recorder must be connected to the tape inputs of the RA-932. Similarly the tape outputs of the RA-932 must be con- nected to the inputs of the recorder. As with other sources be sure to connect the Left and Right channels of each device to the proper channels on the associated components. Use high quality connecting cables to prevent loss of sound quality.

Speaker Outputs 14 and 15

[See Figure 2 for speaker connection illustration.]

The RA-932 has two sets of speaker outputs, labeled MAIN 14 and BI-WIRING 15 . Both sets of speaker outputs are “live” at all times. They are wired in parallel. The combined minimum imped- ance load for the speakers connected to the RA-932 must be at least 4 ohms. If only one pair of speakers is connected, virtually any speaker may be used. However, if two pairs of speakers are connected, all the speakers should have an impedance of 8 ohms or higher. S ee your authorized Rotel dealer if you have any ques- tions.

Speaker Wire Selection

Use insulated two-conductor stranded wire to connect the RA-932 to the speakers. The size and quality of the wire can have an au- dible effect on the performance of the system. Standard speaker wire will work, but can result in lower output or diminished bass response, particularly over longer distances. In general, heavier wire will improve the sound. For best performance, you may want to consider special high-quality speaker cables. Your authorized Rotel dealer can help in the selection of cables for your system.

Polarity and Phasing

The polarity – the positive/negative orientation of the connections – for every speaker and amplifier connection must be consistent so all the speakers will be in phase. If the polarity of one connection is reversed, 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 have 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 speaker and amplifier connection.
