Troubleshooting

5 Troubleshooting

This section lists potential problems with the system, indicates possible causes, and

suggests corrective action. This list does not include every possible problem, but it does

represent some of the more common situations that may occur. If individual components

fail to work, refer to troubleshooting sections in the manufacturers’ manuals. If the

problem persists, contact Daktronics for assistance.

Note:

Be sure to power on the announcer’s rack and cabinet breakers. Make sure all

connections from source to the cabinet are complete.

Sound Cabinet Troubleshooting

Symptom/Condition

Possible Cause

Potential Solution

Poor sound quality from

cabinet (distortion)

Poor source material (CD or

MP3 with heavy compression

or distorted material)

Use high quality audio files

(.wav).

Clipping audio at source

(announcer’s rack) output

Bring source level down below

clip.

Blown driver in cabinet

Play test tones to verify

defective equipment.

Audio from cabinet is

intermittent

Amplifier modules within

control enclosure are

overdriven into protect mode

Reduce source output level.

No full-range audio

One or more outputs muted

Ensure no outputs are muted.

Microphones sound muddy;

too much bass

Subwoofer set too high

Select a different amplifier

preset (low or lowest).

Resistance Check

Check the resistance (ohms) of the lines with an analog or digital multimeter at the back

of the amplifier in the rack and/or at the audio junction box. Compare to the values

shown below. Remember to disconnect opposing cables prior to measuring resistances.

1�

Measure output wires on back of amplifier

(disconnect harness from amplifier).

a�

If measurements match the diagram, this

indicates everything is wired correctly, there is a

solid connection, and the internal crossover in

the speaker is working.

b�

If measurements do not match, proceed with

the next step.

+ YEL

- ORG

+ RED

- BLK

+ BLU

- BRN

+ WHT

All Outputs =

+ WHT & - BLK
