The sub compact CVA50MX-1 is built to meet the rigorous demands of high quality commercial, industrial and Pro Audio sound installations. Its versatile design allows for maximum application flexibility while still maintaining the compact, lightweight form factor of Stewart Audio's CVA Series of amplifiers. The CVA50MX-1 includes an adjustable gain microphone input with a configurable ducking setting allowing the speaker to easily talk over any other channel. With its variety of inputs and the ability to output into either a 4/8Ω setup or a constant voltage
distributed speaker setup, the CVA50MX-1 is an all-in-one solution for any application.
Like all Stewart products, the CVA50MX-1 is designed for sonic accuracy, high efficiency and extended duty cycles through the use of our Signal Sense Technology™.
*CVA50MX-1: When a signal is applied to input 1, inputs 2-4 will be ducked as per the setting of the "duck" control. The level for each input channel is set with the corresponding control. The master volume control and remote volume set the level of all inputs including input 1.
