2-CHANNEL AMPLIFIER 250W 4 Ohm 2U - 230 V
HA 500 is part of the HA series, a line of professional 2U rack amplifiers designed for audio applications in both fixed installations and for portable live use. With a power of 150 W per channel at 8 ohms, 250 W per channel at 4 ohms, and up to 500 W in bridge mode, it is the ideal choice for small to medium-sized systems requiring reliability and sound power in a compact format.
Thanks to its advanced Class-H topology, the HA 500 dynamically adjusts the power supply voltage to the output devices, ensuring it never exceeds the necessary value to support the signal excursion. This design minimizes energy dissipation, improves efficiency at all power levels, and significantly reduces consumption compared to traditional Class AB amplifiers. The result is exceptional audio quality, with extremely low distortion, optimized for high-power applications.
The HA 500 supports various operating modes: independent single outputs, parallel outputs, and mono bridge mode, making it extremely versatile for a wide range of configurations. With a frequency response from 20 Hz to 20 kHz, a signal-to-noise ratio greater than 100 dB, and a total harmonic distortion of <0.5%, this amplifier ensures exceptional sound clarity and vocal intelligibility even in challenging environments.
To protect the amplifier and connected systems, the HA 500 integrates an advanced set of protections, including protection against short circuits, RF interference, and on/off muting, as well as a temperature-controlled variable-speed fan cooling system with front-to-back airflow. This ensures optimal operating temperature and consistent performance, regardless of environmental conditions or workload.
Equipped with speakON connectors, screw terminals, and XLR inputs/outputs, the HA 500 seamlessly integrates into mobile and fixed systems. Its compact and lightweight design (88 x 482 x 239 mm, 9.6 kg) optimizes rack space and ensures reliable and durable performance.
