The LA4X is a high-performance, 4x4 amplified controller designed for professional audio applications, offering exceptional power efficiency, advanced signal processing, and seamless integration with L-Acoustics loudspeaker systems. Engineered for both active and passive setups, this compact 2U rack-mount unit delivers up to 1800 watts per channel at 4 ohms or 1000 watts at 8 ohms—ensuring robust performance across diverse acoustic environments. With its Class D amplification architecture and universal switch-mode power supply featuring Power Factor Correction (PFC), the LA4X supports worldwide mains voltages from 100V to 240V, making it ideal for touring, fixed installations, and live event production globally. This intelligent amplifier integrates dual SHARC 32-bit DSP processors running at 96 kHz sampling rates, enabling precise digital signal management with minimal latency—just 0.84 ms in low-latency mode. The flexible 4x4 routing matrix allows dynamic input-to-output configuration, while built-in linear phase EQ tools (including 8 IIR and 4 FIR filters) provide deep control over frequency response. Advanced features like array morphing, air absorption compensation, and L-DRIVE system protection ensure optimal loudspeaker performance and long-term reliability under demanding conditions. Key technical highlights include Milan-certified AVB networking for high-speed, low-latency audio transport, AES/EBU digital inputs with sample rate conversion, and analog inputs via balanced XLR connections. Its comprehensive I/O setup includes two 1 Gb/s etherCON ports for networked control, four female XLRs for switching between analog and AES3 signals, and four male links for daisy-chaining multiple units. For speaker connectivity, the LA4X provides two 4-point speakON® terminals and one 8-point CA-COM connection, supporting various loudspeaker configurations in line arrays, point-source arrays, or distributed sound systems. Ideal for sound engineers seeking precision, scalability, and cost-effective amplification solutions, the LA4X excels in scenarios requiring multiple loudspeakers driven efficiently from a single chassis. Whether deployed in concert venues, corporate events, theaters, or outdoor festivals, this unit combines the flexibility of traditional powered controllers with the benefits of self-powered speaker technology—offering improved power density, reduced cabling complexity, and enhanced system stability. Users praise the LA4X for its intuitive interface, reliable performance, and consistent sonic quality across complex setups. Many highlight how its integrated loudspeaker management tools simplify tuning and reduce setup time, especially when deploying large-scale line array systems. The inclusion of real-time monitoring and protection mechanisms makes it a trusted choice among professionals managing high-power audio installations worldwide. Common questions often revolve around compatibility with passive speakers, ease of integration into existing networks, and whether the unit supports multi-room distribution. The LA4X seamlessly handles passive enclosures using its four independent channels and offers robust support for Dante-compatible systems through Milan-AVB protocols. Its lightweight yet durable design—weighing just 19 kg and fitting neatly into standard 2U racks—makes it highly portable for touring crews and permanent installations alike. In summary, the LA4X stands out as a versatile, future-ready amplified controller that merges cutting-edge DSP capabilities with energy-efficient amplification. It's an essential tool for modern audio professionals who demand accuracy, scalability, and reliability in their sound reinforcement systems.
