The Stewart Audio AV25 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 D amplifier flexible enough for a broad range of applications requiring quiet amplification.

With an extremely compact form factor, the AV25 allows amplification to be located in places off limits to normal amplifiers without compromising sound or power. Like all Stewart products, the AV25 is designed for sonic accuracy, high efficiency and extended duty cycles. Signal Sense Power Technology™ (SSPT™) ensures the amplifier is only powered when there is a signal present, saving energy and extending product life.
