Todd –
I mean no offense with this post, but I can see that you have little experience with this stuff. A reference loop appears on devices that have GENLOCK INPUTS, with a looping input. The Horita BSG-50 (and others) send a black signal that locks the genlock inputs.
I mention all of this, becuase the Horita requires that you TERMINATE the looping input (of the AJA I/O or AJA K3-Box for example). If you DO NOT TERMINATE the input (with a 75 ohm BNC terminator), it will appear that the Horita BSG-50 is not working. YOU MUST TERMINATE THE LOOPING INPUT. If you loop from VTR to VTR, to I/O to Kona, to something else, the last item in the line MUST BE TERMINATED. This can be the 75 ohm ON switch on a Sony VTR, or it can be a 75 ohm BNC connector that you put on the back of the AJA I/O. If you say “aah screw it, I don’t need it” – THE HORITA WILL APPEAR AS IT IS DOING NOTHING and you will get poor results.
If you say “well, how come AJA doesn’t give you a terminator with the I/O box”, etc. – it’s like saying how come audio mixers don’t come with cables, how come VTR’s dont’ come with tapes. When you get into this business, you have to buy lots of little stuff.
