LINE VOLTAGE SELECTOR SWITCH
Only multi-voltage models are provided with this
switch. U.S., Canadian, European, U.K., and Austra-
lian models are not provided with this switch,
Mains voltages in Saudi Arabia are 127V and 220V
only. Never use this model with 110V setting in
Saudi Arabia.
You will find the line voltage selector switch on the rear pan-
el. Before your model its shipped from the factory, the switch
is set to the power requirements of the destination; neverthe-
less, you should check that it is set properly before plugging
the power cord into the AC outlet. If the voltage is not properly
set, or if you move to an area where the voltage requirements
differ, adjust the selector switch as follows. Before adjust-
ing, disconnect the power cord.
1, Use a medium-size screwdriver.
2. Insert the screwdriver into the groove of the selector
switch and turn it so that the power voltage marking of
your area points to the arrow

Power flows continually to this outlet, regardless of whether the
equalizer is switched ON or STANDBY. Electrical power consump-
tion of the connected equipment should not exceed 100 W. The
equalizer should be disconnected by removing the mains plug
from the AC wail socket when not in regular use, e.g. while on
vacation.
NOTE:
Do not connect appliances with high power consumption
such as heaters, irons, or television sets to the AC OUTLET in
order to avoid overheating or fire risk.
This can cause the equalizer to malfunction.

@) POWER Switch (POWER STANDBY/ON)
When this switch is set to the ON position, power is supplied
to the unit’s main circuits (the spectrum analyzer frequency
display light.) The unit's power switch is geared to selecting
the transformer’s secondary and so even at the STANDBY
position, the unit's circuitry will work as long as the power
cord is connected to the AC power outlet.
Disconnect the power cord from the AC power outlet when
you do not plan to use the unit for a long period of time.
(2 LEFT CHANNEL spectrum analyzer
Displays the amplification of the output signal compensated
with this instrument.
(3) EQUALIZER indicator
@ TAPE MONITOR indicator
@® RIGHT CHANNEL spectrum analyzer
Displays the amplification of the output signal compensated
with this instrument.
@) EQUALIZER CONTROLS
These are equalizer controls for the bands 60 Hz, 150 Hz,
400 Hz, 1 kHz, 2.4 kHz, 6 kHz and 15 kHz.
When the equalizer switch has been set to ON, these controls
may be adjusted. When a control is raised upwards from the
“OQ” position, the frequency band corresponding to that con-
trol will be emphasized; when the control is lowered, the fre-
quency band will be attenuated. These controls can be used
independently for right and left channels.
(D EQUALIZER Switch
When this switch is pressed, the EQUALIZER indicator lights
and its functions become operative. When pressed once
again, this indicator goes out and its functions become in-
operative. Use this switch in the following manner:
ON: When using the equalizer to add sound compensation
to program sources (FM broadcasts, records, tape
playback, etc.).
OFF: When not using the equalizer, normal play back or
recording program sources will be performed without
compensation.
NOTE:
Even when performing playback without using the functions of
this component, if the power switch is OFF, and the equalizer
switch is OFF, there will still be sound. The unit’s tape monitor
switch can also be switched ON or OFF. {TAPE MONITOR in-
dicator will not light. }
@ TAPE MONITOR Switch
When this switch is pressed, the TAPE MONITOR indicator
lights. When pressed again, the indicator goes out. Use this
switch in the following manner:
ON: When using the tape deck connected to the equalizer’s
tape terminals to play back with or without adding
sound compensation.
OFF: When using the components (tuner, turntable, tape
deck) connected to the stereo amplifier to play back
music with or without adding sound compensations,
NOTE:
Pressing the TAPE MONITOR switch ON/OFF during recording
will cause breaks in the recording. To avoid this, do not press the
tape monitor switch while recording.
NOTE:
tn order to protect your speakers from damage resulting from
excessively large inputs, whenever increasing high-frequency
sounds over a wide range, be sure not to raise your ampilifier’s
sound volume too high.

<ARB1121>

USING THE EQUALIZER CONTROLS
The graphic equalizer divides the music source into a number of
frequency bands and boosts or attenuates the level at each of the
frequencies, enabling much finer sound quality adjustments than
ordinary tone controls and sound field compensation.
Some examples of operation are given below.

FREQUENCY RESPONSE
The frequency response of a phono-cartridge or speaker has
peaks and dips in the high range and low range. It can be made
flat by adjusting finely the controls on the graphic equalizer.

2] IMPROVING THE ACOUSTICS OF THE
LISTENING ROOM
The ideal listening room is one where the transmission frequency
response is flat. in actual fact, however, the acoustics vary 2
depending on the effects of the structure of the room and its fur-
niture, and on the listening position.
12
<ARBI121>
glenor saxphone |
Although there is minimal treble attenuation in a listening room
surrounded by hard walls and windows and having a bare floor,
the bass sounds are reflected to a great extent.
in rooms like these, turn up the 150 Hz control sfightly.
in a room surrounded by drapes and with carpets on the floor,
there is minimal reflection of the sound and both the bass and the
treble are absorbed,
in rooms like these, turn up the 60 Hz control slightly and turn up
the frequency controls above 2.4 kHz graduaily.
The above examples are extremely general.
The acoustics undergoes a change in accordance with the fur-
niture in the listening room, the height of the ceiling and the listen-
ing position, among other factors.
Play the music and try operating each of the controls to produce
the best effect.
[3] COLORING THE REPRODUCED SOUND
All instruments and vocals have their own frequency band, as
shown in the figure.
By moving the controls up or down, the volume of the in-
struments preferred can be boosted or other instruments can be
attenuated.
For instance, it is possible to boost the 60 Hz frequency and give
the bass drum a greater “punch” or boost the 1 kHz frequency
and position the vocals st the front. When the 6 kHz frequency is
boosted, the cymbals and “high hat” sound much clearer.
Instruments and vocals have a great many harmonic components
along with the fundamental frequency band and so you can have
lots of fun operating the 7 controls to achieve the sound of your
choice.
NOTE:
In order to protect the speakers from damage resulting from
power overload, do not excessively increase the stereo
amplifier’s volume level when boosting the treble range on this
unit.

USING THE EQUALIZER CONTROLS
OPERATIONS
(4) RECORDING TECHNIQUES USING THE
GRAPHIC EQUALIZER
Coloring the sound of vocals or instruments
The sound of vocals and instruments can be colored at will by
operating the controls. For instance, when the 400Hz, 1kHz and
2.4kHz controls are raised and the other controls flowered,
people's voices sound as if heard on a telephone.
Preventing howl during mixed play
Any irritating howl during play can be prevented by lowering the
knob corresponding to the frequency band in which the how! oc-
curs.
Noise can be reduced during recording and playback
When the high-range controls are boosted in step fashion during
recording and then lowered in reverse fashion during playback,
tape hiss and other high-range noise can be reduced.
