Description
Product description
The HA 500 is part of the HA Series, a high-performance 2U rack-mount amplifier line designed for both installation and live portable audio applications. Delivering 150 W per channel at 8 ohms, 250 W per channel at 4 ohms, and up to 500 W in bridged mode, the HA 500 is an ideal choice for small to medium-sized systems requiring reliability and powerful sound in a compact form factor.
Leveraging advanced Class-H topology, the HA 500 dynamically adjusts the supply voltage to the output devices, ensuring it never exceeds what is required to support the signal swing. This design minimizes energy dissipation, enhances efficiency at all power levels, and significantly reduces energy consumption compared to traditional Class AB designs. The result is exceptional audio quality with low distortion, optimized for high-power applications.
The HA 500 supports multiple operating modes, including dual independent single-ended outputs, parallel outputs, and single-channel bridge mode, making it versatile for a wide range of setups. With a frequency response of 20 Hz to 20 kHz, a signal-to-noise ratio of over 100 dB, and ultra-low total harmonic distortion (<0.5%), this amplifier ensures outstanding audio clarity and vocal intelligibility, even in demanding environments. To protect both the amplifier and connected systems, the HA 500 incorporates a suite of advanced safety features. These include protection against short circuits, RF interference, and on/off muting, alongside a temperature-controlled variable-speed fan cooling system with front-to-back airflow. This design maintains optimal operating temperatures, ensuring consistent performance regardless of environmental conditions or output demands. Equipped with speakON connectors, binding post terminals, and XLR input and loop-thru connections, the HA 500 integrates seamlessly into mobile and permanent setups. Its slim and lightweight design (88 x 482 x 239 mm, 9.6 kg) maximizes space efficiency in rack-mounted configurations while ensuring durable performance.
