5 | Reference Level Adjust

EN
With the Reference level menu option of the setup menu, the analog refe-
rences (input level, dBu/0 dBFS relation) of MM3 MusicMeter can be ad-
apted to local requirements by software. The physical calibration adjusted
at RTW (see 7 | Calibration chapter) shall be unchanged not to lose the
absolute dBu referencing.

5.1 | Input level

MM3 MusicMeter has been calibrated at RTW in the way that a DIN5
scale reads 0 dB, if a reference level of +6 dBu is present and the analog
reference level setting of MM3 MusicMeter is set to +6 dBu. The soft-
ware will automatically adjust the reference level according to the chosen
country during initial boot up. With a scale change like for instance a
British scale this would mean an automatic referencing to +8 dBu for
display "6". With a VU instrument for example with the country selection
US it would automatically be +4 dBu for 0 dB on display. The reference
level setting of +6 dBu on MM3 MusicMeter can be adjusted in steps of
0.1 dBu.
