The sub compact CVA25-1 25V 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 CVA25-1 25V allows amplification to be located in places normally off limits to standard amplifiers without compromising sound or power. The Plenum rating (UL 2043) and remote volume control further compliment the recessing options. Our Signal Sense Power Technology™ (SSPT™) ensures the amplifier is only powered when there is a signal present, saving energy and extending product life. Like all Stewart products, the CVA25-1 25V is designed for sonic accuracy, high efficiency and extended duty cycles.
