HA-900

The HA 900 is part of the HA Series, a high-performance 2U rack-mount amplifier line designed for both installation and live portable audio applications. With an output of 350 W per channel at 8 ohms, 450 W per channel at 4 ohms, and up to 900 W in bridged mode, the HA 900 delivers the power and reliability required for medium to large sound systems, ensuring exceptional audio clarity even under demanding conditions.

Using advanced Class-H topology, the HA 900 dynamically adjusts the supply voltage to the output devices, ensuring energy efficiency while minimizing heat dissipation. This innovative design reduces power consumption compared to traditional Class AB amplifiers, making it an optimal choice for high-power applications. The result is low distortion (<0.5%) and exceptional audio quality across a frequency response of 20 Hz to 20 kHz, with a signal-to-noise ratio exceeding 100 dB. The HA 900 offers flexible operating modes, including dual independent single-ended outputs, parallel outputs, and single-channel bridge mode, making it adaptable for a wide range of audio setups. The amplifier is engineered with a damping factor greater than 200, ensuring precise control over low-frequency transducers, which is particularly beneficial in music applications demanding tight, accurate bass reproduction. To safeguard the system and connected components, the HA 900 features a comprehensive set of protection mechanisms, including safeguards against short circuits, RF interference, and on/off muting. Its robust cooling system, featuring internal heat sinks and variable-speed dual fans with front-to-back airflow, ensures optimal performance and reliability, even during extended use in challenging environments. The HA 900 is equipped with speakON connectors, binding post terminals, and XLR input and loop-thru connections, ensuring seamless integration with various audio systems. Its durable construction and compact dimensions (88 x 482 x 239 mm) make it suitable for rack-mounted configurations, while its 12.0 kg weight provides stability and portability.
