Recording Selector Control 7

Front panel only

Turn the front panel control 7to select the input signal that goes to the record outputs. When you are not recording, set the control to Off. This minimizes the chance of interference from other components in the system.

Having a separate Recording and Listening selector adds a significant degree of flexibility in how you can use the RC-1550. For example by selecting CD with the Record Selector and selecting Tuner with the Listening Selector you can record a CD onto a tape while listening to the tuner.

If you have a three-head recorder or a DAT recorder that allows simultaneous read and write operation, you can monitor the recording by setting the LISTENING control 8 to the Tape 1 or Tape 2 position.

Note: If you select TAPE 1 with the RECORDING control 7, the recording signal will only be available at the TAPE 2 recording outputs. To copy a tape from one tape recorder to another, connect the source recorder to the TAPE 1 inputs and outputs and set the RECORDING control to Tape 1. Connect tape recorder you are copying to to the Tape 2 inputs and outputs.

Controlling Other Components

In addition to operating many of the controls of the RC-1550, the RR-AT94 remote control can operate basic features of some Rotel CD players, DVD players, and AM/FM tuners.

CD Functions DG

The / PLAY, . STOP, , PAUSE, { } TRACK and, RANDOM buttons, and NUMERIC buttons (0 - +10) operate many Rotel CD players after the CD button on the remote has been pressed.

DVD Functions DG

The / PLAY, . STOP, , PAUSE, { } TRACK and RANDOM buttons operate Rotel DVD players, after the AUX1 button on the remote has been pressed.

Tuner Functions F

The BAND, TUNING < >, and additional tuning feature buttons (PTY, TA, TP, etc.) operate Rotel tuners, after the TUNER listening button on the remote has been pressed.

Note: By default, the RR-AT94 operates the Rotel RT-1080/RT‑1082/ RT-1084 tuners. The remote can be reprogrammed to operate the RT‑940AX tuner. This programming only needs to be done once:

To program for the RT-940AX: press the POWER button and the 2 button simultaneously.

To program for the RT-1080/RT‑1082/RT-1084: press the POWER button and the 1 button simultaneously.

Troubleshooting

Most difficulties in audio systems are the result of incorrect connections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RC-1550, refer to the suggestions for the following conditions:

Standby Power Indicator Is Not Lit

The Standby Power Indicator should be lit whenever the RC-1550 is plugged into the wall power outlet. If it does not light, test the power outlet with another electrical device, such as a lamp. Be sure the power outlet being used is not controlled by a switch that has been turned off.

Fuse Replacement

If another electrical device works when plugged into the power outlet, and the Standby Indicator still will not light when the RC-1550 is plugged into the wall outlet, it indicates that the internal power fuse may have blown. If you believe this has happened, contact your authorized Rotel dealer to get the fuse replaced.

No Sound

Check the signal source to see if it is functioning properly. Make sure the cables from the signal source to the RC-1550 inputs are connected properly. Be sure the Listening Selector is set to the proper input. Check the power amplifier for power and proper operation. Check all the wiring between the RC-1550 and the power amplifier, and the power amplifier and speakers.

Remote Control Code Conflicts

Rotel uses the same IR remote control codes for all its audio products. In systems that have multiple Rotel products, the IR control codes of a remote control that is supplied with one product may interfer with the control codes of another product. The RR-AT94 and the RC-1550 can be set to alternate control codes to prevent such conflicts.

To change the IR codes of the RR-AT94, press the Phono button and the 2 button at the same time. To change the IR codes of the RC-1550, point the RR-AT94 at the RC-1550 then press and hold the 2 button for 5 seconds. The LED in the volume control will flash to indicate the IR code has changed.

Note: After changing the remote codes for the remote control and the preamplifier as described above, the remote control will no longer operate the Rotel tuners. To return the RR-AT94 IR code to the default setting, press the Phono button and the 1 button at the same time. To return the IR code of the RC-1550 to the default setting, point the RR‑AT94 at the RC‑1550 and press and hold the 1 button for 5 seconds. The LED in the volume control will flash to indicate the IR code has changed.

Resetting the IR codes

Should you need to reset the IR code, press the MUTE button A on the RR-AT94 remote control for more than 5 seconds while pointing it at the RC-1550. The unit will return to default condition and the Listening CD LED 8 will turn on to indicate the IR code is reset. Contact your authorized Rotel dealer for further information.
