L-Acoustics Launches LA4X Amplified Controller

OXNARD, California -- L-ACOUSTICS is pleased to announce the addition of the LA4X to its amplified controller series.

The LA4X amplified controller is based on a four-input by four-output architecture combining the benefits of self-powered speaker packages with the flexibility of outboard DSP and amplification. The speaker management and amplification for L-ACOUSTICS systems can operate in three different connectivity modes.

"With LA4X, L-ACOUSTICS speakers can virtually be considered as powered speakers, at the same time maintaining the versatility in amplification resources typical of the separated amplification approach," says L-ACOUSTICS Marketing Director Stéphane Ecalle.

A "green" product, the LA4X relies on a universal switch mode power supply suitable for mains from 90V to 265V. The SMPS features Power Factor Correction, which maximizes the amplifier efficiency and takes advantage of nearly 100 percent of the electrical power available with a very high tolerance to unstable mains. Class D amplification circuits ensure the LA4X energy-efficiency for minimal heat dissipation. LA4X delivers 4 x 1000W RMS power at 8 Ohms (or 4 Ohms) with record hold times.

The LA4X inputs are available in analog or digital format. Four cascaded 24-bit A/D converters at the front-end yield a groundbreaking encoding dynamic of 130 dB. AES/EBU digital inputs operate with sample rate converters from 44.1 kHz to 192 kHz. Fallback functions make the creation of redundant audio paths possible.

A dedicated engineering approach combining IIR and FIR filters generates perfectly linearized phase curves and significantly improved impulse responses.  The pool of 8 IIR and 3 FIR filters, the Array Morphing tool and the 1000 ms of delay per channel allow the amplified controller to act as an EQ station and cover the room tuning tasks without the need for external processing. The L-DRIVE protection system carries out a dual analysis of signal level in real-time and RMS.

The design of complex systems is made possible by the integration of the L-NET Ethernet-based network. Thanks to its high-speed data transfer protocol of 100 Mbit/s, up to 253 units can be controlled and monitored in real-time by the LA NETWORK MANAGER software.

For third party management solutions, L-ACOUSTICS provides SNMP support to facilitate the integration via third party control and monitoring systems. As a certified member of the CRESTRON and AMX partner programs, L-ACOUSTICS also provides software modules allowing control integration into their automation systems for the convenience of ultimate technology lifestyle in cultural and event centers, universities, houses of worship and sport facilities.

L-ACOUSTICS is a leading innovator and manufacturer of high-performance loudspeakers, amplifiers and signal processing devices for touring and installed sound markets. Known around the globe for pioneering and championing the modern line array loudspeaker concept with V-DOSC, the company has received numerous accolades for its K1, KUDO, KARA, KIVA, ARCS, XT coaxial loudspeaker systems and SB line of subwoofer enclosures, all powered and processed with the LA4 and LA8 amplified controllers in fulfillment of a "total system approach." Product distribution and customer service for the USA is handled by L-ACOUSTICS' subsidiary in Oxnard, California.
