About Loop Thru
The HD/RGB IN connector (D-sub) and HD/RGB IN connector (BNC) for any
particular channel are linked internally within the unit. So, for example, if analog
component signals are input to the Channel 1 HD/RGB IN connector (D-sub), the
same signals are output from the Channel 1 HD/RGB IN connector (BNC). This
function is called “Loop Thru.”
Using Loop Thru, you can monitor the video output of each video input on a
television monitor, or even use the connections for multiscreen output.
However, the following precautions must be observed.
• Set the TERMINATOR 75
Ω
switch to on when Loop Thru function is not used
When not using Loop Thru, some devices will not function properly unless the
TERMINATOR 75
Ω
switch is set to ON.
• Using more than one pass with Loop Thru may result in attenuation of the video
With three or more V-440HDs connected using Loop Thru, the video signal becomes
more attenuated the further down the signal path the V-440HD is.
When using identical video with three or more V-440HDs, be sure to use a
commercially available video multiplexer.
