There’s a choice of four inputs, but only one can be used at a time:
RGB SCART
RGB JP21
DSUB (VGA-style RGBHV or RGBs)
RCA RGBs jacks
The device can handle both NTSC and PAL signals (toggled via a switch on the side) and has an “RGB Adjust” switch to lower the signal voltage for certain scenarios that are too bright.
Can output two sets of S-VIDEO and two sets composite video at the same time
