The half rack AV Series is built to meet the rigorous demands of high quality commercial, industrial and Pro Audio sound installations. Low cost, lightweight and convection cooling make this Class AB amplifier flexible enough for a broad range of applications requiring compact quiet amplification. Like all Stewart products, the AV50 is designed for sonic accuracy, high efficiency, low power consumption and extended duty cycles. In addition to rack mounting, the AV50 has the option of being pole mounted with projection systems. The AV Series allows bridging to mono for increased power and will also accept unbalanced signals by way of 1/4" TRS input connectors.
