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
Clean the components with the following Christie approved products.
• Clean, dry, microfiber cloth

Installation
To install the speaker, complete the following procedures.
Connecting the speaker wires
Once the speaker is installed, connect the speaker wires to the amplifier.
Notice. If not avoided, the following could result in property damage.
• Always turn off and disconnect the amplifiers from power before making audio connections or
servicing a speaker.
1. Install the speaker according to the mounting instructions provided in this manual.
2. Connect the speaker wire to the positive (A) and negative (B) terminals on the back of the
speaker.
If creating crimped spade lug terminations, use a #8 spade lug (P/N: 145-159106-XX).
A Positive (+) connections
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.
Ceiling mounting the LS2C speaker
To install the loudspeaker on the ceiling, use the appropriate bracket.
1. Remove the four pre-installed M8 button head screws on the back of the loudspeaker.
2. Attach the following bracket to the back of the loudspeaker using the four M8 button head
screws.
• Ceiling mount MM-3RDX-18 (P/N: 111-683209-XX)
3. Alternately, use a properly weight rated and sized U-bracket connected with the two M8
mounting points located on the sides of the loudspeaker.

2. Attach one of the following brackets to the back of the speaker using the four M8 button head
screws.
• Wall tilt bracket BKTW-LSxS (P/N: 145-179108-XX)
• Wall mount bracket MM-024 (P/N: 111-681207-XX)
3. Alternately, use a properly weight rated and sized U-bracket connected with the two M8
mounting points located on the sides of the loudspeaker.
4. Mount the speaker to the wall using the manufacturer documentation provided with the
bracket.
Using the BKTW-LSXS bracket with Christie
loudspeakers
The -01 version of the BKT-LSXS bracket was designed for use with the LS Series surround
loudspeakers. After a minor field modification is performed, the bracket can be safely used with this
model.
When installing Christie Vive Audio speakers and speaker mounting brackets, use a backup safety
system such as a prefabricated safety cable.
Warning! If not avoided, the following could result in death or serious injury.
• Always install all legally required safety straps or cables.
Use experienced certified professionals when installing mounting and rigging equipment. Improperly
installed speakers can result in property damage, personal injury, death, or liability to the installer.
To modify the BKT-LSXS to accept the larger M8 mounting bolts used for this model, using a
suitable metal drill bit no larger than 9mm (23/64”), expand the four mounting holes.

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.
