NO USER-SERVICEABLE PARTS INSIDE REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. WARNING: There are no user serviceable parts inside. Refer all servicing to qualified service personnel. WARNING: To reduce the risk of fire or electrical shock, do not expose the unit to moisture or water. [. . . ] Opening the enclosure of the RA-932 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information. If you are going to be away from home for an extended period of time such as a month-long vacation, it is a sensible precaution to unplug your amplifier (as well as other audio and video components) while you are away. Placement Like all audio components that handle low-level signals, the RA-932 can be affected by its environment. Avoid placing the RA-932 on top of other components. Also avoid routing audio signal cables near power cords. This will minimize the chance it will pick up hum or interference. The RA-932 generates heat as part of its normal operation. The heat sinks and ventilation openings in the amplifier are designed to dissipate this heat. The ventilation slots in the top cover must be open. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating. Remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support it. We recommend installing the RA-932 in furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components. Power Indicator 2 and Power Switch 3 Push in the Power Switch button to turn the RA-932 on. It will help prevent hum and noise. 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 audible 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. 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" inputs. 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. [. . . ] To listen to a tape recording, or to monitor a recording in-progress with a tape recorder that provides that function, set the control to the "Tape" position. The Volume control is a standard control. Turn the control clockwise to increase the volume, or counterclockwise to decrease the volume. The volume of the RA-932 can also be controlled with the small remote control that is provided with it, the RR-AT91. Press the right side of the area labeled <VOLUME> to increase the voume level.
