CLOUD 4 and CLOUD 6 – Installation Guide

Action

Make sure the amplifier channel is being fed an input

signal (preferably via a "signal input" indicator on the

amp).

Check that the amplifier channel's volume is turned

up.

Connect the speaker and cable, which had no output

to another amplifier channel, making sure an input

signal is fed to the new amp channel. If you then get

output, the problem was the amplifier channel. If not,

then the problem may be in the cable or speaker.

Replace the cable(s) connecting the loudspeaker

system and amplifier.

Check all cabling for proper connector contact. A bad

connection can result in intermittent contact or

dramatically increased resistance, which in turn can

cause reduced output or noises unrelated to the

signal.

Check the power tap setting under the speaker grille

to ensure the setting is appropriate for the installation

and amplifier chosen.

Since loudspeakers cannot generate these sounds by

themselves, you may have a faulty electronic device,

or a faulty ground in the signal chain.

When two speakers are hooked up out of polarity, the

low frequencies cancel each other out. Make sure that

the " + " and " – " from the amplifier output are not

crossed on one or more of the speakers.
