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.
? Advanced FPGA + DSP processing technology
? Based on ITU-R BS1770 standard
? Supports 480i 60, 576i 50, 720P,1080i and 1080P resolutions
Supports SDI signal with embedded audio
Up to 8 channels of audio processing with embedded audio
Supports signal loop-out when powered off
Unique noise reduction technology. Amplitude control of only valid data.
Two control modes: auto mode for automatic control of audio amplitude, manual mode for customize adjustment of audio gain
