John Froton said:Yeah .. headphones plugged into the camera via RCA connection will get a better quality sound to monitor than headphones plugged into the mini-jack of the camcorder.
Just get a phono jack to 2 RCA cable (Y cable) if you are using quality headphones like the Sony MDR-7506
The main benefit of the preamp/mixer in between the mic and camera is that they are generally superior to the built in preamps in the camcorder and in addition they give you the ability to mix and match levels from more than one source into the audio track.
it wouldnt work good , you need a headphone amp , this solution works best with external mixer
