VONYX VDA500 2 x 250W 1U PA Amplifier

The VONYX VDA500 is a compact two-channel Class-D PA amplifier delivering up to 500W of stereo output. Designed for small to medium venues, musicians and studio applications, it provides silent operation in a lightweight format.

Its 1U housing suits standard 19-inch rack installation and weighs 2.6kg, making it practical for both fixed systems and mobile setups. Connectivity includes combination XLR and 6.3mm jack inputs, along with NL-4 speaker outputs.

The amplifier produces 250W per channel at 4 ohms or 180W per channel at 8 ohms, with a frequency response of 20Hz to 20kHz. An LED VU meter provides a clear visual indication of overload.
