Front Panel Controls

Volume Control
7
The Volume control is actually two separate controls. The smaller
inner knob controls the right channel, the larger outer knob con-
trols the left channel. The control knobs are "friction connected",
so both controls normally operate together. Turn the controls
clockwise to increase the volume, or counterclockwise to de-
crease the volume.
The two controls can be operated separately by holding one con-
trol knob while turning the other. Normally this is necessary only
to compensate for channel balance problems in the program ma-
terial.
Tone On/Off Switch
When the Tone Switch is in the Off position the Bass and Treble
Control (Tone Control) circuits are bypassed to ensure the purest
possible sound. Leave the Tone Switch in the Off position unless
you want to use the Tone Controls. Turn the Tone Switch to the On
position if you want to adjust the Tone Controls.
Bass and Treble Controls
When the Tone Switch is in the On position, turning the Bass and
Treble Controls adjusts the tone balance of the sound. Turn the
Controls clockwise to increase the bass or treble output. Turn the
Controls counterclockwise to decrease the bass or treble output.
A properly set up high-performance audio system produces the
most natural sound with little or no adjustment of the tone con-
trols. Use these controls sparingly. Be particularly careful when
turning the controls up (clockwise). This increases the power out-
put in the bass or treble range, increasing the load on the ampli-
fier and speakers.

Listening Selector

9
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

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 RA-971MKII.
For example by setting the Record Selector to CD and the Listen-
ing Selector to Tuner you could record a CD onto a tape while lis-
tening 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.

Troubleshooting

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 RA-971MKII refer to the sug-
gestions for the following conditions:

Power Indicator Is Not Lit

The Power Indicator should be lit whenever the RA-971MKII 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 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, but the Standby Indicator still will not light when the
RA-971MKII is plugged into the wall outlet, it indicates that the in-
ternal power fuse may have blown. If you believe this has hap-
pened, 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 RA-971MKII inputs are con-
nected properly. Be sure the Listening Selector is set to the proper
input. Check the wiring between the RA-971MKII and the speak-
ers.
