Introduction
Introduction
X8 live monitoring enclosure
The X8 is a coaxial system designed for live monitoring and short throw sound reinforcement applications with minimum
visual impact. The X8 features a 1.5" diaphragm compression driver coaxially loaded by an 8" low frequency transducer
in a bass-reex cabinet. The L-Vents laminar vented ports reduce turbulence and port noise at high levels to increase LF
efciency.
The X8 operates from 60 Hz to 20 kHz. The coaxial transducer arrangement and its partial horn produce a 100°
axisymmetric directivity output with a smooth tonal response free of secondary lobes over the entire frequency range.
The internal passive crossover network uses custom lters. The L-Acoustics amplied controllers L-Drive parameters ensure
the linearization and protection of the transducers.
How to use this manual
The X8 owner's manual is intended for all actors involved in the system design, implementation, preventive and corrective
maintenance of the X8 system. It must be used as follows:
1. Read the technical description for an overview of all system elements, their features, and their compatibilities.
• Electro-acoustical description (p.11)
• Rigging system description (p.13)
2. Prepare the system conguration. Consider the mechanical limits and the available acoustical congurations.
• Mechanical safety (p.22)
• Loudspeaker congurations (p.23)
3. Before rigging the system, perform mandatory inspections and functional checks.
• Inspection and preventive maintenance (p.27)
4. To deploy the system, follow the step-by-step rigging instructions and refer to the cabling schemes.
• Rigging procedures (p.37)
• Connection to LA amplied controllers (p.67)
The Corrective maintenance (p.68) section contains the operations authorized for the end user.
Performing another operation exposes to hazardous situations.
