TROUBLESHOOTING GUIDE

Should you have a problem with your VERIS 2 loudspeaker(s), find the symptom and follow the associated
WHAT TO DO instructions below. Please note that a particular symptom may have several possible causes.
SYMPTOM
High distortion, low output,
or no output from any or all
drivers.
Distortion from the
loudspeaker at higher
volume levels.
Distortion from the
loudspeaker at moderate to
high volume levels.
Low or no output from the
low-frequency driver.
Low or no output from the
low-frequency driver.
Low or no output from the
mid-frequency driver
(applies to three-way
systems only).
Low or no output from the
high-frequency driver.
Low volume level.
Low volume level.
No sound.
No sound or very low
volume.
Noises from the
loudspeaker (buzzes or
rattles).
Noises from the
loudspeaker (buzzes or
rattles).
Sound cuts in and out at
high levels.
Sound cuts in and out.
Sudden 6 dB loss in sound
level.

SERVICING VERIS 2 LOUDSPEAKERS

Any driver service required can be accomplished from the front of the enclosure by removing the screws
around the edge of the grille. Crossovers and connections may be accessed by removing the rear connector
plate. For warranty repair, contact Community directly or ask us for the location of your nearest Authorized
Service Center.
PROBABLE CAUSE
Faulty connection to the
loudspeaker.
Possible solder joint failure
on crossover card.
Too little amplifier power.
Driver is malfunctioning.
Low-frequency driver,
crossover, or amplifier is
malfunctioning.
Mis-wired NL4 -compatible
locking connector.
Mid-frequency driver,
crossover, or amplifier is
malfunctioning.
High-frequency driver,
crossover, or amplifier is
malfunctioning.
System gain is too low.
Signal or speaker wire
connection is shorted.
Amplifier is not on
or loudspeaker is
disconnected.
No audio signal.
Grille or hardware is loose.
Driver is malfunctioning.
The crossover protection
circuits have been
activated.
Bad connection.
The crossover protection
circuits have been
activated.

WHAT TO DO
Using an ohmmeter, check the continuity of the wiring to the
loudspeaker. If the wiring is OK, remove the input panel and
check all solder joints on the crossover and the wiring to the
drivers. Visually inspect solder joints as cold joints may only
malfunction under high current. Repair as needed.
If the power rating of the amplifier is too low, it will clip at higher
volume levels. Reduce the volume level or use a more powerful
amplifier.
Using a sine wave oscillator or wide range program at moderate
levels, listen to each driver to isolate the problem. Replace as
needed.
Test and replace as needed.
Check wiring and correct as needed.
Test and replace as needed.
Test and replace as needed.
Check to make sure that the audio signal to the amplifier is high
enough to drive it properly. Check all volume/level controls and
gain switches in the system including the amplifier input
attenuator.
Make sure the signal and input wire connections inside all system
connectors are not shorted or open. Even one small wire strand
shorting the +/– signal terminals together anywhere in the
system can cause this problem.
Check that amplifier is turned on and that loudspeaker is properly
connected to the amplifier.
Check that all the audio equipment in the signal chain is powered
on and that all gain controls are in the proper position.
Make sure the front grille screws are securely seated and that any
external mounting hardware is tightened or secured from
vibrating.
Using a sine wave oscillator or wide range program at moderate
levels, listen to each driver to isolate the problem. Replace as
needed.
This usually means that the loudspeaker is being constantly
overdriven and the crossover protection circuits are reducing the
power to the loudspeaker as a protective measure. Reduce the
volume level to the loudspeaker.
Check all connections and cabling for shorts or loose connections.
Even one small wire strand shorting the +/– signal terminals
anywhere in the system can cause this problem.
This usually means that the loudspeaker is being constantly
overdriven and the crossover protection circuits are reducing the
power to the loudspeaker as a protective measure. Reduce the
volume level to the loudspeaker, to restore full dynamic range.
