12. Troubleshooting Guide

Symptom

Possible Cause

Action

No Output From Speakers

Broken Speaker Cables(s)

Check the electrical continuity of

 

 

the loudspeaker cables, and

 

Amplifier

replace if necessary.

 

Check the gain controls on the

 

 

 

 

amplifier are turned up.

 

 

Be sure the amplifier is receiving

 

 

an input signal (check the

 

 

“signal” indicators on the amp).

 

 

Connect the loudspeaker cable

 

 

which has no output to another

 

 

amplifier channel you know is

 

 

working, make sure signal is fed

 

 

to the new amplifier channel. If

 

 

output is obtained from the

 

 

loudspeakers(s) then the

 

 

problem is with the amplifier

 

 

channel or input signal leads. If

 

 

this is not the case then the fault

 

 

may lie in the cabling or the

 

 

loudspeaker.

Intermittent Output

Poor Connection

Check the loudspeaker cabling

 

 

has a good electrical connection

 

 

with amplifier outputs and

 

 

loudspeaker inputs. A bad

 

 

connection can increase

 

 

resistance which will substantially

 

 

reduce the output, or make

 

 

“cracking” noises which are

 

 

unrelated to signal content

 

 

If using multi-strand loudspeaker

 

 

cable, be sure no strands of

 

 

cable are causing short circuits

 

 

between the positive and

 

 

negative terminals of the

 

 

amplifier outputs and/or

 

 

loudspeaker inputs.

Poor Low Frequency

“Out of phase” connection

When two speakers are

Output

 

connected “out of phase”, the low

 

 

frequencies will virtually be

 

 

cancelled out. Check the

 

 

connections at the

 

 

amplifier/speaker paying

 

 

attention to polarity. (see section

 

 

4).

Irregular sounds such as

Poor system grounding

Check and correct system

buzzing and humming

 

grounding.

emanating from the

 

 

loudspeaker

Faulty electronic device in

The speaker cannot generate

 

the signal chain

these sounds on its own. It is

 

 

most likely there is a fault with a

 

 

piece of electronic equipment in

 

 

the signal path.
