The black HDL 6-A Active Line Array Module from RCF is a 2-way active line array module designed for live sound reinforcement and installed sound applications. Powered by a 1400W 2-channel class-D amplifier, it features two 6" neodymium woofers for a solid bass reproduction and a 1.7" voice coil compression driver mounted on a precise 100 x 10° waveguide. The powerful DSP processes the sound including crossover, phase correction, limiting, and protection. The system accept female XLR input connectors and line-level signals from a mixing console or other signal source. The output XLR male connector provides a loop-trough for speaker's daisy chaining. The volume knob controls the volume of the power amplifier. The control ranges from maximum attenuation to the maximum level (maximum output).
