hey guys I have an old rta from the 1980's
2709B 1/3 octave real time analyzer n.e.i

i cant find a manual on it anywhere and i have no idea how to use it properly
 
There's no real particular use for it... You can hook it up to a home stereo if you want pretty lights...
 
well if there really is not a use for it why did the recording studios from th70's through the 80's use them?
so far I know its to tell you where your problems are in acustics anyhow
 
you should look it up google if you really think thats all you do for it

You can use them to tune a room to some extent, yes (although I wouldn't use a 31-band unit), you can use them to find feedback in monitors and what not if you don't have an ear for it -- But for the most part, studios had them because they had pretty flashing lights on them.

They used them because they didn't have anything better. RTAs are time blind. That is, they can't tell a direct path from a reflected path. A measured response could be the true sound of a speaker or it could be the result of a reflection interacting with the direct sound.

RTAs are good for determining the frequency of feedback during a live event. In that situation it doesn't matter as much why there's feedback, it only matters what frequency it is so you can grab the appropriate slider on the graphic eq.
