RCF HDL 28-A

ACTIVE TWO-WAY LINE ARRAY MODULE

• 2200W Two Way Amplifier
• 135 dB Max SPL
• 48 kHz, 32 bit DSP processing
• RDNet Networked Management

The RCF HDL 28-A is a compact, bi-amped, 2-way active touring line-array system engineered for a wide range of indoor and outdoor applications, with a strong focus on outstanding vocal intelligibility. Designed to deliver powerful, precise sound in a lightweight form factor, it is ideal for touring professionals, live events, and fixed installations.

Equipped with dual 8-inch woofers and a high-performance 3-inch titanium compression driver, the HDL 28-A ensures exceptional clarity and definition across the frequency spectrum. Its advanced, time-coherent waveguide is the result of extensive research and development, providing consistent coverage and accurate phase alignment.

Built on the proven design philosophy of the HDL 30-A series, the HDL 28-A features a rugged composite enclosure, zero-degree phase response, and an ultra-linear amplitude response for natural, distortion-free sound reproduction. A powerful 2200-watt Class-D amplifier delivers impressive output levels, achieving up to 135 dB SPL while maintaining excellent audio clarity.

The system utilizes state-of-the-art transducers from RCF, incorporating lightweight neodymium magnets to reduce overall weight without compromising performance. Despite its high acoustic output, the HDL 28-A remains remarkably easy to handle, transport, and fly.

For extended low-frequency performance, the HDL 36-AS serves as the ideal flyable subwoofer companion, perfectly complementing the HDL 28-A array system for full-range, high-impact sound reinforcement.
