JBL VLA C125S Compact Line Array Module

Key Features

Compact line array module optimized for permanent install applications
Advanced technology component transducers for low weight and high output
Outdoor IP55 rated enclosure for protection from dust and water
Comprehensive rigging points for creating a line array configuration
Fiberglass box construction and weatherized components
Dual 15” transducers

The Variable Line Array (VLA) Compact Series is a family of three loudspeaker array modules designed to fill the needs of system designers for applications requiring a more compact line array solution with weather protection for stadia and arenas or any
other project in need of compact line arrays. The VLA Compact Series consists of three loudspeaker array modules:

The C2100, a dual 10” full range speaker with a 100° horizontal coverage pattern
The C265, a dual 10” full range speaker with a 65° horizontal coverage pattern
The C125S, a dual 15” subwoofer

The modular design concept provides the system designer the ability to build large line array systems for larger venue applications or to design smaller line array systems for use as distributed clusters in arenas, domed stadiums and larger performance spaces, including large houses-of-worship.

VLA Compact is designed specifically for permanent installation applications where even coverage, intelligibility, and high sound pressure levels are required.
VLA Compact modules are based on the same advanced engineering used in the highly successful VLA Series line array systems. VLA Compact utilizes the same concept as VLA by providing large format horn-loaded modules with different horizontal horn coverage patterns (100° & 65°). This modular concept provides the designer the flexibility to optimize the horizontal pattern of the line array system by incorporating the appropriate module within the array while still maintaining the vertical directivity.
The VLA-C125S uses JBL proven technology components, featuring dual 15” Differential Drive® transducers.

Enclosures feature multi-layer reinforced fiberglass and steel end-panels. Grilles are zinc plated, powder coated 14-gauge perforated steel with an acoustically transparent black grill cloth backing, a hydrophobic mesh underlayer, and a waterproof rail system.
The rigging system is inherent to the design of the system. Inter-box angles are selected when the array is assembled. Other accessories include a rigging frame, pull-back bar, and a cardioid kit.

JBL continually engages in research related to product improvement. Some materials, production methods and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
