Introduction
The Christie Vive Audio LS1/LS2 Line Source speakers are designed for screen channel or corner
surround use in small to medium sized auditoriums.
Hardware attachment points on each speaker allow for multiple installation options. They are four-
way, bi-amplified type, with separate inputs for low-frequency and mid-high frequency and require the
use of an electronic crossover and two separate amplifier channels.

Maintenance safety
The following guidelines apply when maintaining the speakers.
Caution! Failure to comply with the following could result in minor or moderate injury.
• Only clean the components with Christie approved products.
Notice. Failure to comply with the following may result in property damage.
• Always turn off and disconnect the amplifiers from power before making audio connections or
servicing a speaker.
• Any changes to the product not approved by Christie will void the warranty.
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 speaker components with the following Christie approved products.
• Clean, dry, microfiber cloth

Installation
Complete the following procedures to install the speaker.
All images shown in the installation instructions are of the LS1 speaker; however, these instructions are
identical for the LS2 speaker.
Mounting the speakers on a platform
Use the BKT-LSX tilt bracket to install the speaker on a platform. The tilt bracket is included in the box
with the speaker.
The instructions provided are for mounting the speaker to the platform in a vertical position. To mount
the speaker horizontally, contact Christie Technical Support.
Positioning the speaker behind a perforated screen
When installing speakers behind a perforated projection screen, the optimal distance from the top-
front of the speaker to rear of projection screen is 150 mm (6 inches) once the laser alignment
procedure is complete. This distance provides the best possible speaker performance behind a
perforated screen.
If this distance is not practical due to site conditions, maintain a distance of no less than 100 mm (4
inches) and no more than 300 mm (12 inches) between the top-front of the speaker and rear of the
perforated screen, to avoid deterioration of audio performance.

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).
