STEREO CONTROL AMPLIFIER RC-971

Listening Selector 8

The setting of the Listening Selector controls which of the input signals goes to the main outputs and onto the power amplifier – or, more simply, which source is heard.

Recording Selector 7

The setting of the Recording Selector controls which of the input signals goes to the record outputs. When you are not recording, the Recording Selector should be set to the Off position to mini- mize the chance of interference from other components in the system.

Having a separate Recording and Listening selector adds a sig- nificant degree of flexibility in how you can use the RC-971. For example by setting the Record Selector to CD and the Listening Selector to Tuner you could record a CD onto a tape while listen- ing to the tuner.

There is no Tape 2 position on the Recording Selector. Conse- quently, if you wish to duplicate (“dub”) a recording from one re- corder to another, the source unit must be connected to Tape 1 input. Set the Recording Selector to Tape 1. Connect the unit re- cording the signal to the Tape 2 output.

Phones Output 3

The Phones output allows you to connect headphones for private listening. This output accommodates standard stereo phone (1/4”) plugs. If your headphones have another type of plug, such as a 1/8” mini-plug, you will need an adapter plug. Contact your autho- rized Rotel dealer, to get the correct adapter plug. Note: Plugging in a set of headphones does not cut off the signal to the outputs. The power amplifier will continue to receive a signal and the speakers will continue to play.

Most difficulties in audio systems are the result of incorrect con- nections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the control settings, deter- mine the cause of the fault and make the necessary changes. If you are unable to get sound from the RC-971, refer to the sugges- tions for the following conditions:

Power Indicator Is Not Lit

The Power Indicator should be lit whenever the RC-971 is plugged into the wall power outlet and the Power Switch is pushed in. If it does not light, test the power outlet with another electrical de- vice, 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 Power Indicator still will not light, 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 re- placed.

No Sound

Check the signal source to see if it is functioning properly. Make sure the cables from the signal source to the RC-971 inputs are connected properly. Be sure the Listening Selector is set to the proper input. Check the power amplifier for power and proper op- eration. Check all the wiring between the RC-971 and the power amplifier, and the power amplifier and speakers.
