The ALA-1 Series is designed to provide extremely high
fidelity, controlled pattern, and uniform coverage in smalland medium-sized venues such as houses of worship,
auditoriums, and screening rooms. This easy to use
system takes the difficulty out of designing and installing
with line arrays.
The main array (ALA-1) incorporates four metal-alloy
woofer cone drivers featuring the pioneering voice-coil
guidance system by NEAR, utilizing a unique Ferrofluid in
the magnet gap. Nearly 20 years of proven performance in
the field makes this woofer design the highest definition
and most reliable driver on the market. Listeners will
experience realism and musical detail unlike any other
compact line-array loudspeaker they have ever heard.
The Long-Throw module (ALA-1LT) increases the array
length by 50%, focusing this extra energy to augment and
extend the performance of the ALA-1 for longer distances.
Both models (ALA-1 & ALA-1LT) also use horn-loaded high
frequency metal dome drivers for added clarity and detail
in the upper ranges, without the harshness of traditional
high-frequency units. Like the woofers, each high
frequency unit incorporates Ferrofluid for increased
thermal capacity, better damping, and longer life in harsh
environments.
The Down-Fill module (ALA-1DF) increases vertical coverage
below the main array greatly improving articulation in
front row nearfield listening areas often eliminating the
need for stage-based front fill speakers.
When the application requires high-output low-frequency
energy, the ALA-1S is a perfect partner to the rest of the
ALA system. Its unique mounting bracket allows the full
ALA-1 Line Array to be suspended and tilted. A neodymium
driven 12-inch woofer provides high output and extended
bass for music and video productions. Combined with the
other ALA modules, the full system represents the most
cost-effective way to achieve a true professional-quality
system with unmatched realism.

Processor Notes:
The DLC24 Digital Loudspeaker Controller is a digital engine with an
analog surface. It combines the most advanced technology available
with intuitive interfaces to provide the key elements that ensure
optimal loudspeaker system performance and management in a variety
of live sound and fixed installation applications.
The controller provides factory-set equalization curves to smooth the
response, protect limiting, and active crossovers (for bi-amplified
models and subwoofers). XLR Connector inputs and outputs are
standard on the DLC24 Digital Loudspeaker Controller.
The ALA-1 is a 4 element line array, pre-articulated and fixed in a single
enclosure. The preset vertical coverage creates a 10 degree high output
zone at the top of the array to better reach the back of the average
venue. Sound Pressure Level below this high output on axis zone
gradually decreases towards the bottom of the array. Because the
listening area covered by the bottom of the array is generally closer to
the speaker and the Sound Pressure Level from the speaker is reduced
in this area, Sound Pressure levels will remain very consistent from the
back of a venue to the front.
When a greater vertical coverage angle is required to cover audience
areas at the front of the venue, the ALA-1DF (Down-Fill) module may be
added, increasing vertical coverage by 15 degrees. If higher Sound
Pressure Levels are desired, because of the use of the venue or because
of its depth, the ALA-1LT (Long Throw) module may be added. This module
increases the on axis level by 3 dB and the vertical coverage by 5 degrees.
The relative level of each module has been preset so a complete array
including the LT and DF can be connected to a single amplifier channel.
