When the SPEAKER REMOTE button is at OFF, the sound
from the speakers connected to the REMOTE SPEAKERS
terminals is cut off and you can adjust the headphone
volume with the VOLUME control.
If a speaker system is connected to the DIRECT SPEAKERS
terminals, however, the sound from those speakers cannot
be cut off, so listening through the headphones only is
impossible.
To listen through the headphones alone, do not connect
any speakers to the DIRECT: SPEAKERS terminals.
(4) Speaker Remote Button
Press the button to activate the speaker system connected
to REMOTE speaker terminals on the rear panel. Release
the button OFF to cut off sound from remote speakers.
(5) Tone Controls
Two separate tone controls regulate bass and treble respec-
tively: knob labeled BASS is for low frequency range and
TREBLE for high frequency range.
Rotate the knob clockwise to boost the response, and coun-
terclocawise to cut it.
(6) Balance Control
In the central position, sound is produced in equal level
from both speakers, while turning it to the right decreases
the sound from the left speaker, and turning it to left
decreases the sound from the right speaker.
(7) Tone Selector
With the selector at OFF, the signals do not pass through
the tone control circuit (in order to prevent deterioration of
the tone quality). Therefore the tone controls do not function,
but this unit provides superior tone quality. If the listening
room acoustics are extremely lively or dead and no adjust-
ment is possible by rearranging the furnitures or the speakers,
set this selector to ON. You can then adjust the tone with
the tone controls.
At the MONO position, all the signals are output in mono,
and the tone controls are active.
(8) Tape Monitor Selector
Used to listen to a signal supplied from the tape deck. Set
the selector to TAPE position for the signal from a tape
deck connected to TAPE terminals on the rear panel.
Be sure to set this selector to SOURCE when listening to
a source selected by the input selector.
(9) Function Selector
Select the program source to play or record.
PHONO: Turntable connected to the PHONO terminals.
CD: CD player connected to the CD terminals.
TUNER: Tuner connected to the TUNER terminals.
AV/AUX Video. cassette recorder or video disc recorder
connected to the AV/AUX terminal. Use this selector with
the Tape Monitor selector at the SOURCE position.
(10) Volume Control
This knob requlates the volume level. Rotate the knob
clockwise to raise the volume level, and counterclockwise
to reduce it. When the knob is tuned fully counterclockwise,
no sound is produced. Always have the volume control set
to minimum before you turn on power.

through TAPE MONITOR OUT terminals on unit's rear
panel. Put the tape deck in the record mode to record the
signal. During recording, operation of Volume control, and
Tone Control will have no effect on the signal being sent
through TAPE MONITOR OUT terminals.
Playback With AV/AUX Equipment
The RA-820AX permits connection of one audio-visual or
auxiliary components.
There are one set of audio inputs for a stereo AV component
such as a video disc player or a TV.
This system allows high performance operation for optimal
sound quality such as digital sound from a Hi-Fi video
disc player.
Alternatively the inputs can be used for connection with
an audio equipment such as another compact disc player.
HUM AND NOISE
In any high fidelity installation, hum may be caused by the
interconnection of a turntable, tuner and amplifier, and
speakers as the result of wiring, different grounding or
locations of components.
If hum is experienced with your unit, disconnect everything
but the speakers from the unit. Plug in the turntable and
if hum or howling appears, move the turntable away from
the speakers as much as possible.
Note hum may also be induced by defective cable connec-
tions or by running the cables too close to strong Ac field.
When your unit picks up noise during the reception of
..broad-casts, causes. are mostly due to external objects
-such as fluorescent lamps and house appliances using
motor or thermostat, or others that may induce the noise.
Either relocating the unit away from the noise sources or
using an improved outdoor antenna may readily solve the
problem. In the event you cannot find the cause consult
your dealer or a qualified electrician. `
VOLTAGE SELECTION
Not available for U.K., Canada and Scandinavia
The unit is a variable voltage equipment that can run on
120V, 220V or 240V power supply. Your unit should already
be preset at the proper voltage for use in your area.
However, if you move to an area where the power supply
voltage is different, consult your dealer.
