12 IN CASE OF DIFFICULTY

Should you have a problem with your Community R1 loudspeaker, find the symptom and follow the associated

“What To Do” instructions. Be aware that a particular symptom may have several possible causes. Please

refer to the appropriate section in this manual if you need more detailed information.

SYMPTOM PROBABLE CAUSE WHAT TO DO

No sound. Equipment is turned off. Check and make sure that all equipment in the audio signal path is

turned on. When turning on any piece of equipment, the amplifier

should be not be turned on until all equipment before it is turned on.

No sound Bad or open connection Make sure the signal and input wire connections for all connectors

in the system and to all terminal screws are properly connected or

soldered. Make sure all wire and cables are intact and not severed

or damaged.

No sound Crossover or all the drivers

have completely failed

This would be an unusual cause but could occur with severe abuse

or an adverse amplifier failure. All other possibilities should be

explored before assuming this is the cause. If it is, replace or repair

the failed components.

No sound or very low volume. System control is turned

down.

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.

Low volume level. System electronic gain is too

low.

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.

Low volume level. Signal or speaker wire

connection is shorted

Make sure the wire connections inside all system connectors are not

shorted. Even one small wire strand shorting the +/- terminals either

before or after the amplifier can cause this problem.

Volume level drops and comes back. The crossover protection

circuits have been activated.

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, which is normal.

Reduce the volume level to the loudspeaker.

Sound cuts in and out. Bad connection. Check all connections an cabling for shorts or loose connections.

During high output operation the

volume drops suddenly and does not

come back.

The crossover protection

circuits have “given up”.

This usually means that the loudspeaker was continually overdriven

for an extended period and the protection relays have “fused” in

their protect mode. The crossover must be repaired.

Distortion, low volume, or no volume

from any or all drivers

Cold/open solder joint on the

crossover or faulty wiring

connection.

Using an ohmmeter, check the continuity of the crimp connectors,

all solder joints on the crossover and the wiring to the drivers. Also

visually inspect solder joints as cold joints may only malfunction with

higher current than an ohmmeter supplies. Repair as needed

Distortion from the loudspeaker at

higher volume levels.

Too little amplifier power. If the amplifier being used is too low power, it will clip at higher

volume levels. Reduce the volume level or use a more powerful

amplifier equal to the loudspeaker’s “Program” power rating.

Distortion from the loudspeaker at

higher volume levels.

Driver is malfunctioning. Using a sine wave oscillator or wide range program at moderate

levels, listen to each driver to isolate the problem. Repair or replace

as needed.

No volume for the bass frequencies. Low frequency driver or

crossover is malfunctioning.

Using an ohmmeter, measure the resistance of the input cable (with

the amplifier disconnected). If the meter does not read ~7 ohms,

the LF driver may not be working. Repair or replace as needed.

Low or no volume for the high

frequencies.

High frequency driver or

crossover is malfunctioning.

While right in front of the loudspeaker, listen at low level for high

frequencies. If some are heard and are not distorted, it is probably a

crossover problem. If distorted or no sound is heard, the HF driver

may not be working properly. Repair or replace as needed.

Noises from the loudspeaker (buzzes

or rattles).

Grille or hardware is loose. Make sure the front grille screws are firmly tightened; that any

external mounting hardware is tightened or secured from vibrating

(especially if chains or wires are used in the mounting).

Noises from the loudspeaker (buzzes

or rattles).

Driver is malfunctioning. Using a sine wave oscillator or wide range program at moderate

levels, listen to each driver to isolate the problem. Repair or replace

as needed.
