So I am currently attempting to route my vocals to a dry aux track that I can then send to a stereo us for reverb, but everytime I do the tracks have input echo on them and when i turn it off they are muted!can someone please help>!

This may get moved to the Sonar forum....
 
A screen capture of the track and bus strips (Console View) might help others troubleshoot.
 
I use Photobucket and a freeware capture program.  In case you're not familiar with doing this, here's a link regarding posting screen captures in these forums:

Apply the reverb to the aux track instead. If you really want to send it to a stereo bus then send it normally as you would any other track.

That is how aux tracks work. You have to enable the input echo. I use them like that with no problems and also use sends from the aux track to reverb or delay buses. hth
