Permissible sound pressure level limits
Exposure to extremely high noise levels may cause permanent hearing loss.
Individuals vary considerably in their susceptibility to noise-induced hearing loss, but nearly everyone
will lose some hearing if exposed to intense noise for a sufficient length of time.
Earplugs or protectors to the ear canals or over the ears must be worn when operating this
amplification system to prevent permanent hearing loss, if exposure is in excess of the following
permissible limits provided by the United States Occupational Safety and Health Administration
(OSHA):
Duration (consecutive) Sound level (dbA), slow responses
8 hrs 90
6 hrs 92
4 hrs 95
3 hrs 97
2 hrs 100
1.5 hrs 102
1 hr 105
30 min 110
≤15 min 115
Cleaning products

B Negative (-) connections
3. Connect the negative and positive speaker wires from the speaker to the corresponding
terminals on the amplifier
.
4. Turn on the amplifier and verify that the speaker is receiving an input signal by playing a test
signal through the system.
Mounting the LA3i on an S115 or S215
subwoofer
To install the LA3i loudspeaker and a S215 subwoofer on a platform, use the BKT-LA2/LA3i and BKS-

Troubleshooting
For assistance with common issues, refer to the following troubleshooting topics.
If you cannot resolve your issue with the information provided, contact Christie Technical Support.
The speaker does not function
The speaker is connected to the amplifier, but is not producing any sound.
Resolution
• Verify that the speaker is receiving an input signal from the amplifier.
• Verify that the circuit breaker for the main circuit to the amplifier is closed.
• Verify that amplifier is powered on and attenuators or gain controls are at nominal settings.
• If open, reset the circuit breaker. If the AC mains breaker continues to open, check the voltage
and amperage of the circuit.
• Verify that the speaker wires are correctly connected to the input terminals on the speaker and
the terminals on the amplifier.
The speaker sound is degraded
The speaker is receiving a signal and sound is being output, but it is distorted.
Resolution
• Visually inspect the speaker for deterioration or holes.
• Ensure that the input signal to the amplifier is clean.
• Verify that attenuators or gain controls on amplifies and any audio processors are at nominal
settings.
• Verify that the speaker wires from the speaker are securely connected to the terminals on the
amplifier.
• Verify that the speaker wires are correctly connected to the input terminals on the speaker.
• Verify there are no loose or missing screws. Replace all screws you removed during
installation.
• Have an authorized dealer complete an audio test (for example, pink noise, frequency sweeps,
and content and program material).

There is audible noise from speaker
The speaker is producing audible noise when the amplifier driving it is powered on.
Resolution
• Mute channels, one at a time, to isolate the problem.
• Verify that all line-level cables in the signal chain are in good condition.
• Ensure that the input signal to the amplifier is clean.
• Reroute audio cables away from AC power and lighting cables.
• Verify the correct gain structuring of B chain, input levels, and output levels of source devices
and amplifiers.
