4. CONNECTIONS

WARNING: To prevent the risk of electric shock, do not connect the loudspeaker or

adjust the power selector with the amplifier switched on.

The loudspeaker is designed to be connected to constant-voltage audio lines at 70 V or 100 V.

1. The white wire of the loudspeaker connects

to the positive amplifier output, the black

loudspeaker wire connects to the negative

amplifier output.

2. Use a suitable tool to crimp the two

supplied wires to the ends of your audio

line conductors. Insulate the joints.

3. Using a small flat screwdriver, rotate

the power selector switch to the desired

setting. The specifications section on the

next page shows the power settings for the

three CLA loudspeakers.

4. If your system does not need to reproduce

low frequencies, set the 400 Hz Low Cut

switch to the ON position. This will reduce

the output levels of the frequency range

below 400 Hz.

Precautions

• Before using the loudspeaker, carefully check that all the connections have been

made correctly to make sure there are no accidental short circuits that could

cause electrical sparks.

• Check if your power amplifier’s constant output voltage is 70 V or 100 V, and find

the rated power output.

• The sum of the operating power values of all the loudspeakers connected to the

audio line must not exceed 80 % of the amplifier’s output power.

Verify that the connections to all of your loudspeakers are made correctly “in

phase.” When different loudspeakers reproduce the same frequencies but with

phase differences, there may be sound cancellation. Loudspeakers are often

situated in adjacent positions and the sound waves interact with each other.

If a loudspeaker is connected incorrectly; i.e., the polarity of the audio line

conductors is inverted, the audio signals are transmitted with differences in

phase and correct reproduction is therefore jeopardized. Most notably, the bass

response may suffer.
