How do I monitor vocals when recording through headphones without an echo.

Hi
 
I have Sonar 8.5 Producer and would like help from you friendly people on how to record vocals and to hear them through the headphones. So far I use a button that gives a delayed echo so when my artist sings his vocal appears late and throws his concentration. The sound card I use is a m audio 1010lt and my mixer is behringer xenyx 2222, can anyone help Im desperate?

which driver mode are you using and what is your reported latency?

using the INPUT ECHO button to hear the vocals as you record them will have a delay/echo based on the latency of the system.  reduce your latency and you reduce the echo heard for direct monitoring.

I use a headphone amp/mixer and outboard effects. the headphone amp/mixer enables you to route the signal with effects to the singer and the dry signal to Sonar.

You problem is the lack of a headphone output on the delta. So use your mixer for monitoring.
You mixer has a few options for sending the mike to the delta without sending the playback. You can use a submix buss, or an auxillary out, But this sometimes can be contaminated.   listen carfully for cross buss bleed. Myself I would use the insert jacks.  You can get a clean feed from the Mike buy patching the INSERT jack on the back of your mixer. Push a 1/4 cable only to first click. This steals the signal from the pre amp gain stage only. You could keep them patched like this to a bunch of channels. Looks like you would have 8.

That  term "input echo" is actually quite distracting. Very, very many beginners confuse it for reverb and get lost. They assume that the latency they hear, the "echo", is supposed to be there and don't know where to look for the answer for low latency monitoring.

happens all the time
