HCL-804A comes with 8×4″ midwoofers and 24×0.75″ tweeters. The coaxial transducers with 3 tweeters in an “array within an array” design, allowing smoother off-axis response and wider high frequency directivity. Built-in 8-channel DSP engine and high-performance class D digital amplifier can control each array element with high precision in a programmable manner. It can be separate into two independent beams to control vertical beam angle and width, beam splitting point and sidelobe suppression. It provides simultaneous input of analog audio and AES/EBU digital audio signals to achieve hot backup. System setting and monitoring are all carried out via standard Ethernet, which is efficient and convenient.
