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.

(-1 Black

(+) Rad

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 140W is used, if the input signal is too large or

the volume control is set to loo 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).
