Using a LCD Monitor Behind a Mic

Posted: Fri Oct 26, 2007 6:50 pm

I have a 4'x4' vocal booth. I was going to install a lcd monitor on the wall (behind the mic) so that I can drop lyrics onto it from the control room, to make it easy to pound out song after song. also, I can link it to a camera, and use it as a window. The vocal booth is far away.

Does a LCD Flat Panel monitor give off any noise that will effect a recording? I will put acoustical foam around it, so that all of the sound from the vocalist doesn't just bounce off the screen and come back.

Unless you are unlucky with your choice of LCD monitor, you shouldn't have a problem with electrical noise. Some monitors emit low level continuous acoustic sounds, and also clicks and creaks from the plastic case as the monitor heats up. It would be wise not to run the mains and video down the same cable conduit as the microphone signal.

I think your idea is great in theory but not in practice. You're going to create a nice flat surface right behind your mic that (in all likelihood) will cause a slap-back echo on every vocal track, especially if the singer is within a foot or 2 of the monitor in order see the words.

I think a better approach would be to create a stand (adapt a music or mic stand) with a monitor mount and a connection in the wall rather than the monitor itself. You could alter the angle depending on the height of the singer and put the monitor off-axis to prevent the direct slap back.

The camera idea is a good one, and one that is used regularly.

Another problem is if the booth is, like you said, far away you will lose video signal through DVI cable. I think that approx. 6 meters (20’) is maximum length for standard DVI. For longer line you will need some kind of DVI amp.

Another mic stand, piece of paper and the pen – still works for me Cool
