Hello! I would like to know which shotgun mic is more noisy (self noise) in practise? Here are some specs: 1.AUDIO TECHNICA AT 875 R with signal noise ratio 74 db sensivity 30mv/pa 2. RODE NTG2 with signal noise ratio 76 db sensivity 15mv/pa Lets take look at sensivity. So we need to double signal from RODE (so increase noises a lot) to achieve as good results in signal level as AT right? So theorytical RODE is a lot more noisy? Or im wrong?
