HA-500 - 500W power amplifier

Product Description

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.
