The al-4 Subcompact Line Array System utilizes advanced technologies to extract unparalleled performance from an ultra-compact package. With cutting-edge technologies such as a beryllium compression driver, Kevlar/Neo low-frequency transducers, and precision amplification and DSP, the highly scalable al-4 system brings pristine sound quality and coveted line array performance to more applications than ever before.

Features :
- al-4 elements make it easy to scale al-4 arrays for various applications (one rental inventory serves a variety of applications)
- Fly up to 24 al-4 elements from a single fly-bar
- 90° horizontal coverage angle per al-4 element
- VUE designed 1-inch exit neodymium compression driver with Truextent® beryllium diaphragm
- VUE designed dual 4-inch Kevlar cone neodymium woofers
- Compact and lightweight – each al-4 element is 5.47 x 19.90 x 10.28 inches (H x W x D) and 19.2 lbs.

 
The al-4 Line Array System is made up of the al-4 Acoustic Element, the rack mount V4 Systems Engine, which provides amplification, DSP and system control and the al-4SB flyable isobaric subwoofer, along with a wide range of accessories for suspension and transportation. The system is sold in standard blocks, with eight al-4 Acoustic Elements and a single V4 Systems Engine (designed to power up to 8 al-4 elements) comprising a single block. Multiple al-4 blocks can be combined to address larger applications.

The al-4 by itself produces flat response down to 90 Hz, for applications where extended low-frequency response is required, the al-4 can be arrayed with the al-4SB. It is also fully compliable with the full family of VUE subwoofers so you’re sure to have the output and bandwidth you need for virtually any application requirements. Flexible suspension options allow flying, ground stacking, attachment to a lighting grid and pole mounting on stands or atop VUE subwoofers.
Truextent® Beryllium

The al-Class line arrays use VUE-designed compression drivers with a Truextent® beryllium diaphragm in the center. Beryllium surpasses both aluminum and titanium thanks to an extremely high stiffness / mass ratio, which drastically reduces mechanical deformation (rupture) and shifts the resonance frequencies outside the audible range.
The net result is a more defined HF at much higher SPL than more conventional materials.

Infinitely Scalable
Each “block” of the al-4 subcompact line array system includes eight al-4 acoustic elements and a single V4 Systems Engine Scalable by adding or removing al-4 acoustic elements or by combining multiple al-4 blocks.
Flying accessories, ground stack and optional pole accessories available.
Unlike other compact line array systems that have fixed vertical coverage, the al-4 function works more like full-scale line array systems, with vertical coverage limited only by the number of elements in the array rather than the physical limits of the cabinet design. . This flexibility allows the al-4 inventory to lease a variety of uses. From small one-man shows to more complex productions, climbing up or down is simply a matter of adding more elements to the matrix.
For applications where extended low frequency is required, the al-4 is fully compatible with a variety of VUE subwoofers. Flexible suspension options allow for flight, ground stacking and pole mounting on stands or on top of VUE subwoofers.

- Compact 2U rack mount chassis
The compact V4 Systems Engine is a 2-in / 4-out configuration that provides four amplifier channels, more than enough for two to eight-element al-4.
Inside each V4 chassis are four dedicated amplifiers that provide two channels at 1600W each for low frequency and two channels at 550W each for high frequency.
In addition to amplification, V4 Systems Engine also manages all system processing and management functions, including speaker protection and system-optimized alignment of EQ, tempo and crossover functions. Rear panel signal connections include two XLR and AES / EBU inputs, with a pair of NL4 connectors for speaker outputs
