VIO ALC HD/SD Automatic Digital Amplitude Controller

The VIO ALC is a new product for HD/SD-SDI embedded audio amplitude control. The VIO ALC adopts advanced automatic amplitude processing and advanced technology for reducing and eliminating audio noise. It automatically keeps valid audio data within a required range. The VIO ALC is useful for dealing with amplitude problems in various occasions such as audio jumping between different programs.
