Following in the footsteps of the highly successful K1
system for large stadium tours and outdoor festivals, L-ACOUSTICS announces the
official North American debut of its new K2 line source array loudspeaker
system at InfoComm 2014 featuring PANFLEX™ technology.
The successor to L-ACOUSTICS’ industry-changing
V-DOSC® system, K2 offers K1 performance in a rescaled package that makes it
flexibly well-suited for both permanent installation and touring applications,
from theatre to stadium productions. The primary system components include:
K2
full-range element with PANFLEX™ horizontal steering, operating from 35 Hz to
20 kHz
K1-SB
low-frequency element reinforcing LF contour down to 30 Hz or LF throw down to
35 Hz
SB28
low-frequency element extending the operating bandwidth down to 25 Hz
LA4X
/ LA8
amplified controllers or LA-RAK
touring rack fitted with three LA8
Boasting an unprecedented performance/weight ratio,
sophisticated and fast captive rigging system and exceptional sonic
performance, the K2 line source benefits from L-ACOUSTICS’ Wavefront Sculpture
Technology® (WST). Inter-element angles can be set with laser-like
accuracy up to a generous 10 degrees allowing the optimization of the vertical
coverage with SPL smoothly spread across the audience.
K2 employs L-ACOUSTICS’ new PANFLEX, a unique
horizontal steering technology that combines mechanically adjustable fins with
DSP algorithms effective from 300 Hz. Four different settings are possible: two
symmetric (70° or 110°) and two asymmetric (90° as 35°/55° or 55°/35°).
Narrowing or widening the horizontal directivity can serve many purposes: adapt
to the width of the listening area, fit long and short distance coverage/SPL
requirements, reduce or extend overlapping areas, and avoid reflecting
surfaces.
By combining WST and PANFLEX L-ACOUSTICS exclusively
addresses the control of directivity in both vertical and horizontal planes. As
a result, K2 can match the complex shape of any audience geometry with ideal
sonic performance and minimum noise pollution.
Thanks to its three-way quad-amplified design and full
range capability, the K2 enclosure can be deployed as a standalone line source.
For applications demanding extreme LF impact (contour mode), or maximized LF
projection (throw mode), K2 can be arrayed with its dedicated and flyable K1-SB
LF extension. The K2 system can also address applications with demanding
infrasonic reproduction when combined to the SB28 subwoofer. Before
installation, any system configurations can be acoustically and mechanically modeled
with L-ACOUSTICS’ SOUNDVISION 3D simulation software.
For touring applications, K2 can be associated to the
LA-RAK, a universal distribution platform for power, audio signals and network
that facilitates cross rental between rental companies. LA-RAK houses three LA8
amplified controllers and can be flown onto a K2 array. Other applications can
feature LA8 amplified controllers. For high-end installation projects, K2 can
also be driven by the LA4X amplified controller. The scheme authorizes fully
discrete DSP treatment per section and maximum power headroom for the best
possible sonic performance.
With its dedicated factory
presets, the LA8/LA4X amplified controller constitutes an extremely advanced
and precise drive system for the enclosures. All L-ACOUSTICS amplified
controllers feature the L-DRIVE thermal and over-excursion protection circuit.
Up to 253 LA8/LA4X amplified controllers can be
connected together via the Ethernet-based L-NET protocol. LA NETWORK MANAGER
software allows online remote control and monitoring of all the connected units
via a user-friendly and intuitive graphic interface and features the Array
Morphing EQ. This exclusive tool allows the engineer to quickly adjust the
tonal balance of the system to reach a reference curve or to ensure consistency
of the sonic signature.
