The L-ACOUSTICS LA4X amplified controller is based on a four-input by four-output matrix architecture and uses a universal switch mode power supply suitable for mains from 90V to 265V. A “green” product, the power supply features something they call “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 4x1000W 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.
