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
2 hrs 100
1.5 hrs 102
1 hr 105
30 min 110

Safety Information
Vive Audio LA2 Speaker User Manual 5
020-101262-02 Rev. 1 (10-2016)
• 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 required 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.

020-101262-02 Rev. 1 (10-2016)
Introduction
This user manual provides speaker installation, troubleshooting, and specification information.
Speaker overview
The LA2 articulated coaxial ribbon line array speaker is designed for use as part of a screen channel in
auditoriums with approximately 150 to 250 seats, or for use as a corner surround speaker in
auditoriums with approximately 250 to 350 seats when paired with an S215 subwoofer and bi-amped.
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. Multiple hardware attachment points on the speaker allow for multiple installation
options.

Troubleshooting
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 speaker 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 from the speaker are securely connected to
the terminals on the amplifier.
• Verify that there are no missing screws. Replace all screws that you removed during
installation.
• Have an authorized dealer complete an audio test (for example, pink noise, frequency sweeps,
and content and program material).
Caution! Failure to comply with the following could result in minor or moderate injury.
• Do not service the speaker. All servicing must be completed by qualified service
personnel.

Troubleshooting
Vive Audio LA2 Speaker User Manual 14
020-101262-02 Rev. 1 (10-2016)
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.
•Checkthepolarity.

aMeasured at distances of 4m and 8m, in free field and on ground plane. Sensitivity is calculated based on measured
SPL response averaged in the 200 Hz-5 kHz range and scaled back to 1 m.
bAES 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.
cAveraged in the 500 Hz-16 kHz range, at -6 dB. Screen scattering effect results in a slight increase of coverage at
high frequency.
