Safety Information

• Read this information thoroughly before installing or operating a speaker.

• Read these instructions.

• Keep these instructions.

• Do not install near any heat sources such as radiators, heat registers, stoves, or other devices
(including amplifiers) that produce heat.

• Do not use this apparatus near water.

• Do not install the speaker near water where the electrical components can be exposed to
moisture. Do not place objects containing liquids, such as vases, on the product.

• Clean only with a dry cloth.

• Do not overpower or underpower speaker systems.

• Use only in accordance with manufacturer’s specifications and installation guidelines.

• 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 sufficiently intense noise for a sufficient time. These are the
permissible noise level exposures specified by the United States Occupational Safety and Health
Administration (OSHA):

Duration (Consecutive) Sound Pressure Level (dbA), Slow

Responses

8 hrs 90

6 hrs 92

4 hrs 95

3 hrs 97

Safety Information

Duration (Consecutive) Sound Pressure Level (dbA), Slow

Responses

≤15 min 115

• According to the OSHA, any exposure in excess of the above permissible limits could result in
some hearing loss. 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 described limits.

• Two people are required to safely lift and install the speaker.

• Speakers and speakers mounted to brackets must be affixed to a suitable structure following all
local safety standards and regulations.

• Always install all legally required additional redundant safety straps or cables.

• Install the minimum number of rigging wires (refer to Installation for more details) that are
required to suspend the speaker. Observe load ratings and all applicable local safety codes.

• Only use attachments or accessories specified by Christie.

• To reduce the risk of system damage, turn off the power amplifier and then disconnect the
speaker wire before performing a repair or maintenance.

• All servicing must be completed by qualified service personnel. Servicing is r eq u i red when the
apparatus has been damaged in any way. For example, liquid has been spilled or objects have
fallen onto the apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.

• Changes or modifications to the product not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

020-101264-03 Rev. 1 (02-2017)

Introduction

This user manual provides speaker installation, troubleshooting, and specification information.

Speaker overview

The LA5 articulated coaxial ribbon line array speaker is designed for use as part of a screen channel in
auditoriums with approximately 500 or more seats, or for use as a corner surround speaker in
auditoriums with approximately 500 or more seats when paired with two S215 subwoofers and tri­amped.

It may also be used for a range of other applications, where vertical coverage and maximum throw
distance are appropriate.

The speaker contains an internal passive crossover, allowing it to operate with a single channel
amplifier. Multipl e hardware attachment points on the speaker allow for multiple installation
options.

• Allow speakers exposed to extremely low temperatures to warm for a minimum of one
hour before playing them at typical application levels. Failure to comply may result in
equipment or property damage.

• Speaker wire affects sound quality. Make sure the speaker wire quality and gauge are
appropriate for your application.

Complete the following procedures to install the speaker.

Connect the speaker wire

Notice. Failure to comply with the following may result in property damage.

• The amplifier must be turned off and unplugged before you start this procedure.

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

Troubleshooting

Caution! Failure to comply with the following could result in minor or moderate injury or
damage.

• Do not service the speaker. All servicing must be completed by qualified service
personnel.

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 power from the amplifier.

• Verify that the circuit breaker for the main circuit to the amplifier is closed.

• Reset the circuit breaker. If the AC mains breaker continues to open, check the voltage and
amperage of the circuit.

• Verify that the negative and positive speaker wires from the speak er are correctly connected to
the terminals on the amplifier.

The speaker sound is degraded

The speaker is powered on and sound is being produced, but it is distorted.

Resolution

• Visually inspect the speaker for deterioration or holes.

• Reduce the output level of the source.

• Verify that the negative and positive speaker wires fro m the speake r are securely connected to
the terminals on the amplifier.

• Verify that there are no missing screws. Replace all screws that you removed during
installation.

Christie Vive Audio LA5 Speaker User Manual 14
020-101264-03 Rev. 1 (02-2017)

Troubleshooting

• Have an authorized dealer complete an audio test (for example, pink noise, frequency sweeps,
and content and program material).

There is speaker noise or hiss

The speaker is producing static noise or hiss when powered.

Resolution

• Mute channels, one at a time, to isolate the problem.

• Verify that the cables are in good working condition.

• Reroute audio cables away from AC power and lighting cables.

• Verify correct gain structuring of B Chain and input and output levels of source devices and
amplifiers.

•Check the polarity.

AES refers to the AES2-2012 standard. IEC refers to the IEC 60268-5 standard. Maximum continuous SPL is
calculated based on sensitivity and AES power handling. IEC short-term power is tested using IEC pink noise with a
9 dB crest factor. The crest factor was specifically increased to reflect real life parameters of digital cinema
soundtracks. Maximum peak SPL is calculated using peak voltage during the IEC short-term power test.

c

Averaged in the 500 Hz-16 kHz range, at -6 dB. Screen scattering effect results in a slight increase of coverage at
high frequency.
