SYSTEM
The L-ACOUSTICS
®
K1 system has achieved international recognition and is today the prime choice of engineers for
the largest stadium tours and outdoor festivals. Its sonic performance, its fully integrated system package and its rider
friendliness are considered as the industry benchmarks. With K2, L-ACOUSTICS
package. The K2 system flexibility makes it suited to both permanent installation and touring applications, from theatre
to stadium productions.
The main system components are as follows:
K2, full-range element, with adjustable horizontal directivity, 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
The 3-way quad amplified design, the transducers resources are among the characteristics giving K2 an exceptional
ability to perform in many applications and with a record-breaking performance/weight ratio. Any on-site deployment
can be easily and quickly achieved thanks to an extremely ergonomic, fast and captive rigging system.
A K2 line source utilizes the unrivalled characteristics of Wavefront Sculpture Technology
set with laser like accuracy up to a generous 10˚, allowing the optimization of the vertical coverage with SPL smoothly
spread across the audience. Horizontally, the K2 coverage pattern can be adjusted to sector and match any audience or
specific room geometries. Four different settings are possible: two symmetric (70° or 110°) and two asymmetric (90° as
35°/55° or 55°/35°).
Thanks to its 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 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 which 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.
Thanks to dedicated factory presets, the LA8/LA4X amplified controller constitutes an extremely advanced and precise
drive system for the enclosures. All L-ACOUSTICS
excursion protection circuit.
Up to 253 LA8/LA4X amplified controllers can be connected together via the Ethernet-based L-NET protocol. The 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.
