HA-1500 - 1500W power amplifier

Product Description

Leveraging advanced Class-H topology, the HA 1500 dynamically adjusts the supply voltage to the output devices, minimizing energy dissipation while maintaining optimal performance. This design significantly reduces power consumption compared to traditional Class AB amplifiers, making it ideal for high-power applications. With ultra-low distortion (<0.5%) and a frequency response of 20 Hz to 20 kHz, the HA 1500 delivers outstanding clarity and fidelity across all audio ranges. Designed for versatility, the HA 1500 supports dual independent single-ended outputs, parallel outputs, and single-channel bridge mode, ensuring compatibility with a wide range of professional audio setups. Its signal-to-noise ratio exceeding 100 dB and damping factor greater than 200 provide precise low-frequency control, making it an excellent choice for bass-heav applications and high-fidelity sound reproduction. To ensure safe and reliable operation, the HA 1500 features comprehensive protection mechanisms, including safeguards against short circuits, RF interference, and on/off muting. A robust cooling system with internal heat sinks and variable-speed dual fans ensures consistent thermal management, even during prolonged high-demand use.

The HA 1500 is equipped with speakON connectors, binding post terminals, and XLR input and loop-thru connections, enabling seamless integration with professional audio systems. Despite its high power, the amplifier maintains a compact design with dimensions of 88 x 482 x 227 mm and a weight of 12.0 kg, offering portability and space efficiency in rack-mounted setups
