{"product_id":"hdl-28-a","title":"RCF HDL 28-A Active Two-Way Line Array Module","description":"\u003cp\u003eThe RCF HDL 28-A is a compact bi-amped 2-way active touring system for a wide range of applications, both indoors and outdoors, with an emphasis on vocal intelligibility. It features two 8-inch woofers and an impressive 3-inch titanium compression driver. The time coherent waveguide is the result of in-depth research and design. Following the HDL 30-A philosophy, the HDL 28-A shares the composite material cabinet, the zero-degree phase and ultra-linear amplitude response. The built-in 2200 watt class-D amplifier delivers excellent playback clarity and up to 135 decibels SPL max. The RCF HDL28-A features state of the art RCF transducers with lightweight neodymium magnets. Considering its acoustical power, it has a remarkably low weight for easy handling and flying. The HDL 36-AS is the ideal flyable bass complement for the HDL 28-A array system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2200W Two Way Amplifier\u003c\/li\u003e\n\u003cli\u003e135 dB Max SPL\u003c\/li\u003e\n\u003cli\u003e48 kHz, 32 bit DSP processing\u003c\/li\u003e\n\u003cli\u003eRDNet Networked Management\u003c\/li\u003e\n\u003cli\u003e2 x 8\" Neodymium Woofers, 2.5\" voice coil\u003c\/li\u003e\n\u003cli\u003e1.4\" Titanium Compression Driver, 3.0\" voice coil\u003c\/li\u003e\n\u003cli\u003eExclusive FiRPHASE technology on-board\u003c\/li\u003e\n\u003cli\u003e750 Hz Crossover Point\u003c\/li\u003e\n\u003c\/ul\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\u003eThe acoustic beauty of the symmetry\u003c\/h3\u003e\u003cp\u003eThe symmetrical design of the cabinet produces identical left and right coverage. The component positioning and special DSP crossover filtering of the HDL 28-A take care of the constant directivity without spots of break up or attenuation. The specially-designed front baffle provides coplanar woofers, controlled LF dispersion and a central space to host the 4PATH waveguide. The heavy-duty front grille is powder coated. A special transparent-to-sound foam backing inside helps to further protect the transducers from dust. For weatherproof capabilities, a rain cover is available.\u003c\/p\u003e\u003ch3\u003ePowerful class D amplifiers\u003c\/h3\u003e\u003cp\u003eRCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. HDL amplifiers deliver a ultra-fast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the HDL amplifiers present SMPS power supply section to produce maximum output and minimum weight.\u003c\/p\u003e\u003ch3\u003ePRECISION SYSTEM DESIGN AND SIMULATION\u003c\/h3\u003e\u003cp\u003eRDShape is a 3D sound system design and acoustic-simulation platform for RCF and TT+ Audio speakers and subs.
