First function layer
• Level
(First layer, button/key 1 – toggle function linked to Level Var)
This function features the
dBu converted values
of the
reference levels of the analog inputs and outputs and the
calibration levels of the test signal generator which can be
adjusted in the
Reference Levels menu.
The factory settings for the
Calibration Reference Le-
vels
adjusted in dBFS are:
• –20 dBFS RMS
• –18 dBFS RMS: EBU adjustment level (–3 dBu)
• –9 dBFS RMS: Maximum allowed signal level
pursuant to EBU, 0 dB on the
peak meter (LMPSL) (+6 dBu)
The resulting dBu values depend on the selected
Re-
ference Level Standard
which is also adjusted in the
Reference Levels menu, so the button/key 1 can display
different values.

vel var
, see below) in 1 dB steps.

(First layer, button/key 3 – toggle function linked to Level)
This function selects the variable output signal level set
with the buttons/keys

dBu value of Calibration Reference Level 2 set in Refe-
rence Levels
menu (see also
