![]() the modern DIN ‘peak flux’ of 250nWb/m reads +4VU. I personally favour aligning mechanical meters to the old ‘0VU = 160nWb/m’ standard is it makes them waggle much further into the useful range on typical material. If it’s -1VU then the deck is aligned to 250nWb/m = 0VU which makes 160nWb/m read -4VU. If it’s at/near +3VU then the deck’s alignment is likely 160nWb/m = 0VU. It is one standard by why have only one method of measuring it when you can have two! You can infer the chosen meter alignment by where the Dolby mark on the meters (if they have one) is located. The one fixed point in cassette is the Dolby level of 200nWb/m (ANSI) aka 218nWb/m (DIN). what magnetic flux level corresponds to the 0 mark on the meter. Steady state signals should read much closer to one another subject to… music) I would expect the mechanical meter to under-read by a good 5dB or so depending upon material (bass heavy or highly compressed material will have less of a difference). There are at least two factors going on here.įirst off mechanical VU meters vs quasi-peak reading electronic meters (unless emulating a mechanical meter) will not read the same on dynamic material (ie. ![]() You’re sort of comparing apples to oranges.
