CONNECTION OF SPEAKER
CABLES
Depress the push-terminal and insert the speaker cable
from the amplifier into the terminal hole. The plus side is
marked red and the minus side marked black.
(-) Black
<♦) Red
Notes :
• The cable which fits in the hole of the push-terminal,
should have a diameter not larger than 7/64' (2.6
mm). To ensure proper fit to the terminal, a cable
diameter of less than 5/64" (2 mm) is recommended.
• The sheath of the speaker cable should not be
inserted into the terminal hole.
• When the speaker cable is of a stranded type, the
core conductor should be twisted before inserting it
into the terminal hole.
PROTECTION CIRCUIT
• The speaker has a protection circuit. When an exces¬
sive input is applied to the speaker, the protection cir¬
cuit is activated to attenuate the input level.
• When the protection circuit is activated, the sound
pressure level of the woofer is sharply reduced and
tweeter is cut off. In this case, turn down the volume
control of the amplifier and wait until the protection
circuit of the amplifier and wait until the protection
circuit is automatically reset(about 2 to 20 seconds).
• If, during operation of the protection circuit, the ampli¬
fier volume level is not reduced or it is increased after
the sound has become low, the protection circuit will
operate repeatedly, which may damage the speaker.
POWER HANDLING CAPACITY
The maximum input to the speaker is 140W (continuous
program). Care should be taken not to apply excessive
input or abnormal signals to the speaker.
• When using a high output amplifier, be careful of set¬
ting the amplifier volume control to avoid excessive
input.
• Even when an amplifier with maximum output of less
than HOW is used, if the input signal is too large or
the volume control is set to too high position, the
amplifier output may be distorted, possibly damaging
the speakers, Special care should be directed to the
amplifier input and output levels.
• When bass and treble levels are increased by the tone
control, loudness
control or equalizer of the amplifier, a large power may
be applied to the speaker.
So all controls should be set with care.
• When the following special signals are applied to the
speaker system, a large current flows into the speaker
which may result in damage to the voice coil even
when such signals are below the maximum input level.
In this case, be sure to turn down the volume control
of the amplifier.
1. Inter-station noise in FM broadcast.
2. High frequency noise during fast-forward or
rewind operation of a tape deck.
3
Feedback from microphones or electronic musi¬
cal instruments.
4. Shock noise caused when the power switch of the
amplifier or condenser microphone is turned on or
off, or at connection and disconnection of the
input/output terminals.
5, Continuous high of low frequency signal devel¬
oped from an oscillator or electronic musical
instrument (music synthesizer).
