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 |
≤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 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.

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. Multiple hardware attachment points on the
speaker allow for multiple installation options.

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 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).
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.

146 dB peak
System coverage| 120° horizontal dispersion, 50° vertical dispersion
Sensitivitya, 1 W/1 m| 103.5 dB (mid-frequency), 102 dB (high-frequency)
Recommended amplifier power| 1500 W – 2150 W (FTC) @ 4 Ohms / Christie CDA3 or
Christie CDAS (depending on application)
Rated impedance| Mid-frequency: 4 Ohms
High-frequency: 3 Ohms (linear impedance through entire audio band)
a Measured 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-3 kHz range and scaled back to 1 m.
b 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.
