HA-4000 - 4000W power amplifier

Product Description

Built on advanced Class-H topology, the HA 4000 dynamically adjusts the supply voltage to its output devices, optimizing energy efficiency while minimizing heat dissipation. This innovative design significantly reduces power consumption compared to traditional Class AB amplifiers, ensuring exceptional audio quality with ultra-low distortion (<0.5%) and a frequency response spanning 20 Hz to 20 kHz. Its outstanding signal-to-noise ratio of over 100 dB guarantees pristine sound reproduction across all frequency ranges. Designed for versatility, the HA 4000 supports dual independent single-ended outputs, parallel outputs, and single-channel bridge mode, making it suitable for a variety of professional applications, from large-scale live events to high-fidelity permanent installations.

With a damping factor greater than 200, the HA 4000 ensures precise control over low-frequency drivers, delivering tight, impactful bass and exceptional clarity. Safety and reliability are at the core of the HA 4000’s design. It features a robust set of protection mechanisms, including safeguards against short circuits, RF interference, and on/off muting, ensuring the safety of both the amplifier and connected systems. Its temperature-controlled cooling system, with internal heat sinks and variable-speed dual fans, maintains consistent performance even under the most demanding conditions. The HA 4000 offers seamless connectivity with speakON connectors, binding post terminals, and XLR input and loop-thru connections, ensuring compatibility with a wide range of professional audio setups. Despite its immense power, the amplifier is designed for ease of use and installation, with compact dimensions (88 x 482 x 239 mm) and a durable build weighing 23.1 kg.
