Meters
�
6 LED meter is calibrated 0dBFS = +22dBu (the maximum level which can
be correctly converted by the optional internal A/D converter before
overload occurs). The meter calibration points are as follows:
Meter panel calibration value in dBFS / Equivalent dBu value
0dBFS / +22dBu
-2dBFS / +20dBu
-6dBFS / +16dBu
-12dBFS / +10dBu
-18dBFS / +4dBu
-42dBFS / -20dBu
