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.
