| Reference loop
• | | | |
Hi,
I'm connecting a Kona LH (using the KL-Box) to a betacam UVW-1800. I'm also using a Horita BSG-50 to feed the reference. I just want to make sure my setup is ok, regarding the reference loop.
Here is what I've done :
1- Horita out to ref loop in the KL-Box
2- ref loop of the KL-Box to the REF video input of the betacam.
Here is where I have a doubt, should the 75ohm switch be turn on or off on the betacam or should I loop it back to the Horita.
Also for the XLR analogue inputs, should I flip the switch to 600ohm or to 1k ohm, when connected to the Kona?
Last question, for the RS-422 connection I'm using a stealth serial port connected by USB in the MacPro, would I gain anything by using the RS-422 connection from the KL-Box instead?
Thank you,

On and don't loop back as the BSG50 is output only.

Leave it @ 600 (switch to on).

Performance and perhaps accuracy.
Set analog color space on in and out on your Kona Control Panel to betacam.

#1 - make believe the Stealth port does not even exist. Use only the AJA RS422 port.
# 2 - if you have anything unterminated when using a Horita BSG-50, it will not work. You MUST have the termination switch ON for this to work.
These are the cables that you want to hookup - don't ask, just do what I say -
Black from BSG-50 to Beta 1800 Ref video input
Black from BSG-50 to Beta 1800 VIDEO INPUT (I know that you are using analog component to work, but send black into the composite video input - just do it)
Black from BSG-50 to Kona REFERENCE input, and TERMINATE the input with a 75 ohm BNC terminator.
Dont' forget - forget using the stealth serial port.
