The RCF HDL 28-A is a compact and high-performance 2-way active line array system, designed for small and medium-sized events that require clear, powerful audio and a quick, easy setup. This system features two 8-inch neodymium woofers and a large 3-inch titanium compression driver, providing excellent sound reproduction and remarkable vocal clarity. The HDL 28-A uses advanced transducer technology and a 2200W Class-D amplifier to deliver crystal-clear audio and a maximum sound pressure level of up to 135 dB. It is perfectly suited for a wide range of applications, both indoors and outdoors, with an emphasis on high intelligibility and extended frequency response.
Engineered for efficiency and clarity, the HDL 28-A incorporates RCF's FiRPHASE technology, ensuring zero-degree phase distortion and a linear amplitude response. The system's time-coherent waveguide plays a crucial role in achieving exceptional vocal intelligibility and a controlled dispersion pattern, minimizing spots of breakup or attenuation. The DSP system onboard offers tailored processing with a 750 Hz crossover point for optimal performance and clarity across the frequency spectrum. With 48 kHz, 32-bit DSP processing, the system ensures pristine sound quality and allows for precise tuning in both high and low-frequency ranges.
As part of RCF's innovative approach, the HDL 28-A utilizes a well-crafted composite material cabinet that is both lightweight and durable. This design allows for easy handling and fast setup, reducing the time required for transportation and assembly. Additionally, the symmetrical cabinet design ensures identical left and right coverage, with a horizontal coverage angle of 100° and a vertical coverage angle of 15°. The system's versatility is further enhanced by its advanced rigging concept, allowing for seamless integration into J-shaped or spiral arrays. The hardware is compatible with quick, reliable rigging setups, and up to 20 HDL 28-A modules can be fastened to a single flybar.
RDNet compatibility is a standout feature of the HDL 28-A, offering remote monitoring and control via a proprietary network protocol. RDNet enables users to adjust parameters such as EQ, delay, and level for each connected device within the system. This allows for flexible and efficient sound management in live performance environments, ensuring optimal performance regardless of the venue size. The DSP processing also allows for precise management of the system's presets, with additional subwoofer configuration options available for enhanced bass response when paired with the HDL 36-AS subwoofer.
The HDL 28-A's performance is complemented by RCF's continued development of high-quality transducers. The system uses lightweight neodymium magnets in both the woofers and the compression driver, providing high efficiency and minimal distortion. The powerful Class-D amplifier ensures excellent dynamic response, delivering both fast transient response and consistent output across the entire frequency range. The subwoofer's setup, integrated with RDNet, provides a complete, scalable solution for demanding sound reinforcement needs.
