The VP-551X Scaler/Switcher from Kramer is a versatile, professional presentation scaler/switcher for 4K60 4:4:4 HDMI, VGA, and composite video signals. This unit scales the video and provides options to use the embedded HDMI audio or to select the companion audio channel from one of ten analog audio input signals. After processing and scaling, the embedded AV signal is sent to the HDMI and the HDBaseT outputs simultaneously. The audio is also sent to a balanced stereo audio output, S/PDIF digital output, and a pair of loudspeakers.
