Kramer Electronics The VP-731 is a 9-input scaler/switcher for analog video, digital video, balanced stereo and S/PDIF audio signals. It up or down-scales composite, s-Video (Y/C), component video (YUV), HDMI, computer graphics video and JPEG files to a selectable computer graphics video or HDTV output resolution on one HDMI and two 15-pin HD outputs. It includes a power amplifier to drive loudspeakers. The unit provides glitch-free switching between sources through FTB (fade-thru-black) switching technology. The VP-731 is the same as the VP-730 with the addition of Ethernet control.
