Thank you for selecting the Technics
Hi-Fi
Speaker
System
SB-CS65.
To
obtain maximum
satisfaction from all
of its many features as well as the lon-
gest possible service, be sure to first
read these instructions carefully.
INSTALLATION OF YOUR SPEAKER
SYSTEM
The sound reproduced by a speaker system iseasily
influenced by such factors as room acoustics and
the place where it is placed in the room. Before final-
ly deciding upon the place where the speaker sys-
tems are to be placed, please carefully read the fol-
lowing information.
e In general, if a speaker system is placed on the
floor, near a corner or near a wall, the level of the
bass sound will be increased by the reflections of
the sounds from the wall and floor. Consequent-
ly, itis possible to adjust the bass sound to some
extent
by changing
the distance
between
the
speaker systems and the wall and/or floor. Deter-
mine the location of the speaker systems which
gives the best sound
reproduction,
therefore,
depending
upon
the actual
conditions
of the
room in which they are to be used.
e lfthespeaker system faces toward a hard wall ora
glass door or window,
it is recommended
that
curtains or similar material be used in order to
prevent undesirable resonance and sound reflec-
tion, especially of the treble sound.
e Vibrations
from
the speaker
systems
may
be
transmitted to a record player, causing acoustic
feedback
("howling").
For
best
results,
the
speaker systems should not be placed near the
record player, and should never be placed on the
same table or shelf as the record player. Itis often
very effective, in order to prevent "howling", to
place a thick piece of felt beneath the speaker
systems and the record player.
CONNECTING
THE SPEAKER
SYSTEM
e
Be sure to turn off the power of the amplifier be-
fore connecting the speaker systems to it.
e The impedance of this speaker system is 8 ohms.
Be sure that the load impedance of the amplifier
to be used is 4 - 16 ohms.
e When connecting speaker wires to the amplifier,
be sure that the left and right connections and the
plus and minus connections are made correctly.
m—h
. Twist the core of the tip of the wire.
2. Push the knob on the terminal and insert the wire
into the terminal
hole until the core cannot be
seen. (Do not insert the insulation part.)
3. Release
the knob
and confirm
that the wire is
- connected properly.
Be sure that the core wires don't touch each other.
POWER-HANDLING
CAPACITY
The power-handling capacity of this unit isindicated
in the specifications, and is determined according to
the temperature increase of the voice coils.
e lf the amplifier to be used has an output power
which exceeds the power-handling
capacity of
this unit, be sure that the amplifier's volume con-
trol is set so that excessive input is not applied to
the speaker system.
e Even if the amplifier to be used has an output .
power
which
is less than the power-handling
capacity of this unit, the output of the amplifier
will become distorted and excessive input will be
applied to the speaker units, especially for the
middle and high frequencies, if the input signals
to the amplifier are too large or the amplifier
volume level is too high. Also note that higher-
than-normal power is applied to the speaker sys-
tems
if the tone controls of an amplifier or a
frequency equalizer are used to raise the level of
bass and/or treble sounds. When adjusting the
volume
level, therefore, do so with great care:
confirming that amplifier output is not distorted.
e
Thepower-handling
capacity of this unit is set for
reproduction of ordinary music. If an oscillator or
test record is used to produce a continuous signal
such as a sine wave, etc., a signal exceeding 2
watts must never be applied. Usually, 1 watt of
sine wave
is enough
to test a speaker system
when an oscillator or test disc is used.
e If the following special types of signals are ap-
plied to the speaker system, be sure to reduce the
volume level of the amplifier.
1. Interstation hiss on the FM broadcast band.
2. Output fróm a tape deck during fast forward or
rewind.
3. Acoustic feedback from a microphone or an elec-
tric musical instrument.
