A lot of productions still use a ' single system ' workflow mostly small budget shoots and documentary etc where the field mixer mixes multiple sources onto 2 channels on the camera . Good for speedy and efficient workflow , if the mix is good ! <| sep |> Glad I bought the SHP 9500 s for $ 50 a couple days ago instead of waiting to see if the HD 598 SE went to $ 100 like the Cs were listed for BF . I got some headphones that people compare to HD 598 SE and a Boompro mic for less than the HD 598 s would be if they had gone on sale . I feel content now . <| sep |> You don ' t have to have any money , Just get out there , walk away for a while from the misery . I did this last year when I was so , so down didn ' t buy anything , but for several hours I felt so great .
