Transducers work at full performance and the SPL output is more than doubled. Furthermore, we improved the power supply section with a tripled current level on fast transients, for a level of detail usually achieved only in high-end studio monitors.\u003c\/p\u003e\u003ch3\u003eFaster and more powerful\u003c\/h3\u003e\u003cp\u003eThe 4K amplifier is an essential part of HDL 50-A reengineering effort. The 4000 W RMS Class-D power operates at very low impedance producing a quick and detailed transient response, while the high damping factor improves sound quality and detail. The HDL 50-A 4K power section is tailored to the transducers and the cabinet design to reach excellent efficiency, low distortion and high signal-to-noise ratio. The amplifier module features a solid machined aluminum structure that stabilizes the amplifier during transportation. The control panel on the back adjusts volume, bypass, delay, presets and advanced functions. The signal input preamplifier features a double opto isolation to avoid noise and ground loops.\u003c\/p\u003e\u003ch3\u003eDSP Processing\u003c\/h3\u003e\u003cp\u003eNew generation DSP handles processing inside the cabinet and allows for the adjustment of Cluster size and HF projection. The low-latency 32 bits DSP section deploys a remarkable amount of processing power for live performances with straight-forward control and monitoring of individual sections of the module, including the onboard inclinometer and transducer performance via RDNet. An entire set of protections preserve product life and reliability. All settings are controllable by the encoder on the rear of the cabinets or using the integrated RDNet remote management. The easy-to-access control panel allows for simple optimizations of the module.\u003c\/p\u003e\u003ch3\u003eNETWORKED CONTROL AND MUCH MORE\u003c\/h3\u003e\u003cp\u003eRDNet is an advanced platform for integrated monitoring and control of sound systems - from small live and installed setups to massive arena systems. Based on a robust networked architecture, RDNet combines system control, line array design, and comprehensive audio measurements into a single powerful software package. Engineers and technicians can intuitively manage every device on the network, from individual components to multiple groups. The platform provides full DSP control of compatible devices, with flexible configuration tools for perfectly tuning the system response at maximum speed. Users have real-time access and oversight of all key settings from a centralized interface.\u003c\/p\u003e\u003ch3\u003eV-shaped symmetrical design\u003c\/h3\u003e\u003cp\u003eThe symmetrical design of the cabinet produces identical left \/ right coverage.
