RA-1062Stereo Integrated Amplifier
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-1062 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.
The RA-1062 is supplied with an RR-AT94 remote control and must be placed where the infrared signal from the remote can reach the front panel Remote Sensor.
Cables
Keep power cords, digital cables, and audio cables away from each other. This will minimize the chance of the audio signal cables picking up noise or interference from the power cords or digital cables. Using high quality, shielded cables will also help to prevent noise or inter- ference. If you have any questions see your authorized Rotel dealer for advice about the best cable to use with your system.
Remote Control
The RA-1062 includes an RR-AT94 remote control that operates many of the controls of the RA-1062. In addition, the remote operates basic features of some Rotel CD players, DVD players, and AM/FM tuners.
Audio Controls 
The RR-AT94 duplicates the basic audio func- tions of the RA-1062 front panel. When a function is available on both the front panel and the remote, a number (see front panel illustration) and a letter (see remote control illustration) are shown in the instructions. For example, to change the volume level, you can either turn the control on the front panel or use the buttons on the remote. When only one identifier appears, that control is avail- able only on the front panel or the remote, but not both.
CD Functions 
The PLAY, STOP, PAUSE, TRACK 
and 
, RANDOM buttons, and NUMERIC keys (0-10) operate many Rotel CD players after the CD button on the remote has been pressed.

DVD Functions 
The PLAY, STOP, PAUSE, and TRACK ±, buttons operate Rotel DVD players, after the AUX1 button on the remote has been pressed.
Tuner Functions 
The BAND, TUNING, and additional tuning feature buttons operate Rotel tuners, after the TUNER button on the remote has been pressed.
Remote Sensor 
The remote sensor receives infrared signals from the remote control. Do not cover or block the sensor. It must be unobstructed or the remote control will not work properly.
The operation of the remote sensor can also be affected if it is exposed to bright sunlight or certain types of lighting (such as halogen lights) that emit infrared light. In addition remote control functions may not work reliably if the batteries in the RR-AT94 are weak.
NOTE: To use the remote, aim it at the remote sensor on the front panel of the RA-1062.
Remote Control Batteries
Two UM-4/AAA size batteries (supplied) must be installed before the remote control can be used. To install the batteries, remove the cover on the back of the RR-AT94. Install the batter- ies as shown in the illustration in the battery well. Test the control for proper operation, then replace the cover. When the batteries become weak the remote control won’t operate the RA-1062 consistently. Installing fresh batteries should eliminate the problem.
NOTE: Remove the batteries from the re- mote if it will not be used for a long period of time. Do not leave run down batteries in the remote control; they can leak corrosive chemicals which will damage the unit.
Speaker Outputs
See Figure 3
The RA-1062 has two sets of speaker outputs, labeled SPEAKER A and SPEAKER B. The speaker outputs are controlled by the switch on the front panel.
Speaker Impedance
If only one set of speakers will be used at any given time, the speakers may have an imped- ance as low as 4 ohms. If there are times when both the A and B speakers will be used, all the speakers should have an impedance of 8 ohms or more. Speaker impedance ratings are less than precise. In practice, very few loudspeakers will present any problems for the RA-1062. See your authorized Rotel dealer if you have any questions.
Speaker Wire
Use insulated two-conductor stranded wire to connect the RA-1062 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 degraded. 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 conductors (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.
