Electro-Voice PA4150L Power Amplifier

The Electro-Voice PA4150L power amp combines outstanding audio performance, exceptional reliability and secure operational safety in a compact 2RU chassis design.

All models in the PA Series provide several protection circuits which not only prevent the power amplifier itself but also the connected loudspeaker systems from being damaged. These protections include Dynamic Audio Limiters, Inrush Current Limiter, Short Circuit Protection and Thermal Overload Protection. All PA-Series power amps feature different hi-pass filters with switch selectable cut-off frequency to attenuate unwanted low-frequency signals. Infinitely variable low-noise high performance fans guarantee absolute thermal stability while keeping fan noise to a minimum.

Direct “flow-thru” chassis design allows for a smooth flow of air from front-to-rear, which allows trouble-free operation even in smaller amp-racks. Compact high density power supply units with low-leakage toroidal transformers provide extensive headroom far above the listed power rating. Premium phoenix style screw-lock connectors prevent accidental disconnection resulting in a more secure connection of audio signal and speaker cables.
