hello there.



if a handheld vocal mic has a polar chart like this one

http://www.audio-technica.com/cms/wired_mics/b8f2c39b7aa5fc9c/index.htm



is it not giving a false reading off its off axis rejection as it has an added ring (worth 5db's) i.e. at 120% and at 1kHz the mic is not 30 db's down but in fact 25? because with the added ring your not actually counting from directly behind its on axis point at 0%





if so it it the same case with this mic





Link removed



at 2000Hz the mic isn't down by 30db's but 25 for the same reason as the first mic?





thanks

it shows the relative sensitivity at various frequencies and positions around the capsule



most sensitive directly in front and at all the freqs

least sensitive at 1k at both 120 and 240 deg



looking at the back of the mic is difficult to gauge the other freq because they have use the dotted line and not continuous coloured lines
