Hi Ty and all. I currently use a SD 302 and Sony 7506 headphones. I also supply the same to camera operators I work with , insures we are monitoring with the same quality. My question is I would like to had more headphones for others to listen on the set. How would I do this ? I see Sound Devices makes a HXE headphone monitoring unit but in reading the specs on it it says it only takes a line level signal. Since I send a mic level to some cameras at times I don't think this would work. Any ideas or solutions for me other than moving up to a 442 which I think has two outputs that can be set to line or mic?
