Rack-mounted screens

[Corabar Steve]

Why can't you just put a simple phono splitter in the video feed?

My plan as detailed above would need a 3 way split (one to each screen & one to the output socket) What worries me is would a 3 way split cause too much signal degradation. As the karaoke machine we have has 2 outputs, putting 2 inputs on the case seemed the most logical thing to do (& worry about whether I can link it to additional TVs at a later date)

What sort of splitter did you have in mind?

If you are using phono (RCA) plugs for the composite video input then one of these: http://www.cables4all.co.uk/phono-rc...ated-503-p.asp

To save on cabling if you just have one video input to your screens you could always use the second output from your karaoke machine for the third (and fourth) output if you decided to double up.

Any advantage of that over something like these?

if YOu were wanting to split the signal inside the case, why not just solder 2 cables to the back of the din plate and have one yellow rca on the end of each one for each tv, this wil do exactly the same as the above splitter be cheaper and less to go wrong rattle loose and come undone, you could also then if you wanted run a patch internally to the second socket so uou have a tv out too .
ive split the signal from my av amp at home 4 times from comp video and it works absolutly fine

No, they will work also. If the split feeds were 10's of meters long then you would need to have an active splitter but you shouldn't have a problem with such short runs.

They are through sockets there was no soldering involved. I don't really do soldering as the experience with the Powercons showed.

Very impressive, it's a shame that I can't see them in action as early as I wanted to

You cant split a video signal with a simple passive splitter because the levels will be all wrong. A video signal is terminated by a 75ohm resistor and by connecting two monitors in parallel you will be reducing that to 37.5 ohms and the 1v p-p signal will drop significantly.

At best, you will see a noticable drop in brightness and the colour will appear deeper, at worst the picture will become unstable or even resort to a blue mute screen if the TV does that in the absence of a signal.

Professional monitors have video in and out and have a switchable termination so you can loop through multiple monitors with just a single termination on the last monitor.

What you need to do the job properly is something like these...

A picture is indeed worth a thousand words. I had completely misunderstood the concept as described to me ( it was my fault ).

An excellent setup there, I'm mightily impressed. Food for thought.
