The 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 HDL 28-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.
MONITORING AND MANAGEMENT NETWORK
The new version of RDNet offers comprehensive improvements. The audio system is now configurable in Groups of boxes or in the new Array clusters, the Air Compensation and Cluster Size processes are now more precise and controllable, as well as the FiRPHASE filter gain. Subwoofers configuration is now faster, even in complex EndFire configurations.
The RCF HDL 28-A features state-of-the-art RCF transducers with neodymium magnets. RCF’s experienced engineering teams have specially developed and matched each component — starting from the power supply through the input board to the amplifiers and transducers right up to the complete HDL 28-A System

The advanced rigging concept derives directly from its big brothers:
the RCF HDL 30-A and HDL 50-A. The integrated mechanics are both fast and reconfigurable, allowing the system engineer to create J-shaped and spiral arrays. The hardware is designed for easy and fast setup. The angle can be adjusted on the ground before the system is hung and slipped automatically into the correct position as the array is pulled up. Up to 20 HDL 28-A modules can be fastened on a single flybar.
