The sub compact CVA50-1 Priority PA is designed to meet the demanding operational and budgetary environment of the classroom market. The typical classroom has two amplification requirements, local sound reinforcement, and school wide paging which are usually two separate systems. The CVA50-1 Priority PA has a built in priority 25V paging input which eliminates the need for redundant speakers and upstream amplification saving costly installation labor and hardware. A compact form factor, plenum rating (UL 2043), multiple inputs (plus 25V PA) and remote volume control make this amplifier ideal for today's classroom design. 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 CVA's are designed for sonic accuracy, high efficiency and extended duty cycles.
